BACKGROUND
[0003] Ultrasound imaging can provide real-time two-
dimensional imaging of a patient's
body, which can be used to assist a healthcare professional to locate a region
to insert an invasive
medical device (e.g., a needle or a cylindrical instrument such a trocar,
etc.). Once the healthcare
professional locates the correct insertion point, the healthcare professional
may then begin the
medical procedure, such as insertion of a catheter, administration of a local
anesthetic, or removal
of tissue as in a biopsy. Determining at what orientation to insert the
invasive medical device to
ensure an unobstructed path to the target is challenging, as the ultrasound
monitor can only display
structures within the patient's body. It can also be difficult to tell what
path the medical device
will follow before the device enters the patient' s body. Furthermore, after
the medical device
enters the patient's body, it can be difficult to accurately track the path
and position of the medical
device on the ultrasound monitor. Using the needle as an example¨unless the
needle is positioned
exactly in-plane with the image, the needle may not be visible or may only be
partially visible,
which means that the needle location or, more importantly, the location of the
needle tip is not
precisely known. As such, the healthcare professional may make numerous
attempts to insert the
device before properly entering a tissue mass or penetrating a blood vessel.
Further, in the case of
a nerve, the healthcare professional can often only estimate the location of
the needle end if it is
not visible on the ultrasound image. As a result, patients may be injured or
made to suffer
unnecessary pain. From the healthcare professional's perspective, these
procedures can be time
consuming, and can expose the healthcare professional to liability. These and
other drawbacks
exist.
[0004] Accordingly, there is a need for improved systems,
methods, and devices that provide
guided instrument placement within the body.
SUMMARY
[0005] Aspects of the disclosed technology include systems,
methods and devices for guided
instrument placement. Consistent with the disclosed embodiments, an exemplary
device can
include an instrument guide device and a transducer system. The instrument
guide device can
comprise an instrument guide, an instrument guide insert, and an instrument
guide bracket The
instrument guide can include a first aperture, a magnet, and one or more
protrusions. The
instrument guide can be configured to secure at least one instrument. Further,
the instrument guide
CA 03139694 2021-11-26
WO 2020/264383 PCT/US2020/039938

can be adaptable to secure instruments of different sizes. Turning to the
instrument guide bracket,
the instrument guide bracket can be removably attachable to the instrument
guide when at least a
first protrusion of the instrument guide engages with at least a first opening
of the instrument guide
bracket.
[0006] The transducer system can comprise an ultrasound
probe bracket and an ultrasound
probe. The ultrasound probe bracket can include a first sensor, a transceiver,
and a processor. The
fir St sensor can be configured to determine a position of the instrument
guide device by wirelessly
tracking the magnet located in the instrument guide. That is, as the
instrument guide is moved
around a body, the first sensor tracks the magnet to determine the position of
the instrument guide
device. The ultrasound probe bracket further includes a transceiver that is
configured to receive
the position of the instrument guide device from the first sensor, and then
output the position to an
external device (e.g., a computing device). The ultrasound probe bracket can
further include a
cutout sized to allow the instrument guide device to fit within and a member
(e.g., snap features,
protrusions, cutouts, and/or spring-loaded inserts) that allows the instrument
guide device to
removably attach to the ultrasound probe bracket. In some examples, rather
than the cutout, the
ultrasound probe bracket can include a single or pair of protruding features
that provide attachment
to the instrument guide bracket. The ultrasound probe bracket can be sized to
fit around the
ultrasound probe and can be removably attachable to the ultrasound probe. The
ultrasound probe
can generate and send image information to the processor. Then, the processor
can generate
position data using the position of the instrument guide device and/or the
image information_
[0007] In some embodiments, the instrument guide can
include a plurality of instrument guide
inserts having different instrument sizes and/or gauges.
[0008] In some embodiments, the instrument guide can
include a single insert that can be
rotated to different positions to create different apertures sized to
accommodate different
instrument sizes and/or gauges.
[0009] According to some embodiments, the instrument guide
insert can be sized to fit within
the first aperture, wherein the at least one instrument is secured to the
instrument guide insert_
[0010] In some embodiments, a first insert can be
positioned into a second opening of the
instrument guide bracket from an exterior surface of the instrument guide
bracket. Also, the first
insert can be further positioned into the instrument guide along a central
axis such that the
CA 03139694 2021-11-26
WO 2020/264383 PCT/US2020/039938
4
instrument guide is rotatable along the central axis and that the first insert
induces friction that
causes the instrument guide to maintain its orientation.
[0011] According to some embodiments, the ultrasound probe
bracket is adaptable to fit a
plurality of geometries.
[0012] In some embodiments, in response to movement of the
instrument guidance system,
the instrument guide remains positioned in the same orientation as a first
instrument secured by
the instrument guide.
[0013] In some embodiments, a first instrument is removably
attachable to the instrument
guide when the first instrument is inserted within a second aperture
perpendicular to the instrument
guide's axis of rotation.
[0014] In some embodiments, the instrument guide includes a
rotation lock configured to allow
and prevent rotation of the instrument guide.
[0015] According to some embodiments, the processor of the
ultrasound probe bracket can
determine whether the instrument guide is attached to the instrument guidance
system. Also, the
ultrasound probe bracket can include a second sensor configured to provide
power and disengage
power to the instrument guidance device when the instrument guide is attached
or detached,
respectively. It should be noted that the first sensor can perform all or some
of the functions of
the second sensor and vice versa.
[0016] An exemplary method includes a computing device
receiving imaging data from an
ultrasound device, which the computing device can display. The computing
device can also
communicate with an instrument guide device to receive position data that
indicates an angle of
an instrument attached to the instrument guide device. The computing device is
preprogrammed
with: 1) the physical location of the instrument guide device's axis of
rotation relative to the
imaging surface of the ultrasound transducer; and 2) an algorithm to compute
the pixel distance
on the display corresponding to a physical metric in the ultrasound image
(e.g., centimeters) at any
given imaging depth. Then, the computing device can determine where the
trajectory of the
instrument should lie on the ultrasound image in real-time. The generated
image can then be
displayed on a screen of the computing device, for example, as a graphical
user interface (GUI).
[0017] In some embodiments, the ultrasound device can
receive the position data from the
instrument guide device and can generate the image overlay in a manner similar
or identical to that
disclosed above in reference to the computing device.

DETAILED DESCRIPTION
[0076] Some implementations of the disclosed technology
will be described more fully with
reference to the accompanying drawings. This disclosed technology can be
embodied in many
different forms, however, and should not be construed as limited to the
implementations set forth
herein. The components described hereinafter as making up various elements of
the disclosed
technology are intended to be illustrative and not restrictive. Many suitable
components that would
perform the same or similar functions as components described herein are
intended to be embraced
within the scope of the disclosed electronic devices and methods. Such other
components not
described herein can include, but are not limited to, for example, components
developed after
development of the disclosed technology.
[0077] It is also to be understood that the mention of one
or more method steps does not imply
that the methods steps must be performed in a particular order or preclude the
presence of
additional method steps or intervening method steps between the steps
expressly identified.
[0078] Reference will now be made in detail to exemplary
embodiments of the disclosed
technology, examples of which are illustrated in the accompanying drawings and
disclosed herein.
Wherever convenient, the same reference numbers will be used throughout the
drawings to refer
to the same or like parts.
[0079] FIG. 1 is a schematic of an exemplary system 100
used for instrument guidance. As
shown, the system 100 includes a computing device 110, an instrument guidance
device 120, and
an ultrasound device 130. The instrument guide device 125 can include a first
aperture, a magnet,
and one or more protrusions. In some examples, rather than the magnet the
instrument guide device
CA 03139694 2021-11-26
WO 2020/264383
PCT/US2020/039938
17
125 can include a sensing element (e.g., a potentiometer, a feature to engage
with a potentiometer,
an optical sensing element that can be used by an optical sensor, and/or a
capacitive sensing
element that can be used by a capacitive sensor). Further, the sensing element
can be contained in
an instrument guide insert that is attached to the instrument guide device
125. The computing
device 110 can include one or more processors 112, transceiver 114, and
display 116, among other
things. The computing device 110 can communicate with the instrument guidance
device 120
and/or the ultrasound device 130.
[0080] As one skilled in the art would understand, the
ultrasound device 130 can emit high-
frequency sound waves that, when a transducer of the ultrasound device 130 is
placed against a
body, reflect off body structures. The ultrasound device 130 can then receive
the waves and can
use the waves to create imaging data. Here, the ultrasound device 130 can send
the imaging data
in real-time to the computing device 110.
[0081] As shown in FIGs. 2A¨B, the instrument guidance
device 120 can include ultrasound
probe 121, ultrasound probe bracket 122, instrument guide device 125, first
sensor 123A, second
sensor 123B, ultrasound transceiver 124A, and ultrasound processor 124B. The
ultrasound
transceiver 124A can be located in ultrasound probe bracket 122 and can
transmit various data
including position data and a unique identifier for the ultrasound probe 121.
The first sensor 123A
and/or second sensor 1238 can be a magnetoresistive sensor, Hall effect
sensor, magnetic
potentiometer, and/or the like that can be configured to detect a magnetic
field and changes as the
magnetic field is rotated and/or translated.
[0082] Turning to use of the instrument guidance device
120, a user (e.g., a physician) can
place the instrument guidance device 120 near a portion of the body (e.g., the
neck) to approximate
an area to insert an instrument. The instrument guide device 125 of the
instrument guidance device
120 can hold one or more instruments of differing sizes, which can be
attributed to a multi-faceted
block which can rotate beside an open channel to create a closed channel of
variable size (shown
in FIG. 2C). Additionally or alternatively, the instrument guide device 125
can include a plurality
of disposable instrument inserts that are each designed to fit a specific
instrument guide, but each
has a consistent outer geometry to attach. Also, the instrument guide device
125 can include a
single instrument insert that includes a plurality of faces or a single
continuous face that when the
instrument insert is twisted, changes the size of a second aperture created
between the instrument
CA 03139694 2021-11-26
WO 2020/264383
PCT/US2020/039938
18
insert and the instrument guide device 125, which can allow for different
instrument sizes and/or
gauges to be used. In some examples, the instrument guide device 125 can be a
single disposable
instrument guide that accepts a plurality of instrument sizes. An instrument
inserted into the
instrument guide device 125 can be indirectly and/or removably attached or
attachable to the
ultrasound probe 121.
[0083] As the user moves the instrument guidance device
120, the magnet can change
orientation accordingly; however, the magnet can be in a fixed position in
rotating element of the
instrument guidance device 120, such that the magnet does not change the angle
and/or position
relative to the rotating element. The first sensor 123A can wirelessly track
the magnet, using for
example magnetoresistive properties that rely on the magnetic field, to
determine an orientation
(e.g., angle) and/or position of the instrument guide device 125. Then, the
ultrasound processor
124B can generate position data (e.g., angle and positioning values), which
can be in relation to
the surface of the ultrasound probe 121. More specifically, the first sensor
123A can send a voltage
within a range (e.g., 0-3.3 volts) corresponding to the angle of the magnet to
the ultrasound
processor 124B. The ultrasound processor 124B can convert this voltage to an
integer within a
range (e.g., 0-1023 for a 10-bit analog-to-digital conversion). Using the
transceiver 124A, the
instrument guidance device 120 can send the position data, using for example
Bluetooth
technology, to the computing device 110.
[0084] Furthermore, the second sensor 123B can provide
power to the instrument guidance
device 120 when the instrument guide device 125 is attached. Conversely, the
second sensor 123B
can disengage power to the instrument guidance device 120 when the instrument
guide device 125
is detached.
[0085] Referring to the computing device 110, the computing
device 110 can receive the
imaging data and the position data from the ultrasound device 130 and the
instrument guidance
device 120, respectively_ The computing device 110 can then generate an image
overlay using the
imaging data and the position data. The image overlay can project the position
data onto the
imaging data. Further, the computing device 110 can display the image overlay
on the display 116
of the computing device 110 or in some examples, the computing device 110 can
send the image
overlay to an external device and/or the ultrasound device 130 that displays
the image overlay.
Additionally or alternatively, the computing device 110 can project the image
overlay over a screen
CA 03139694 2021-11-26
WO 2020/264383
PCT/US2020/039938
19
of the ultrasound device 130, using for example lasers, or by placing a see-
through screen over the
screen of the ultrasound sound device 130. In other words, the position of an
instrument can be
mapped onto the imaging data that shows an image of the body. Thus, in real-
time, for example,
a healthcare professional can see the position of an instrument and a blood
vessel, which can
eliminate errors.
[0086] In some examples, the instrument guidance device 120
may need to be assembled prior
to use. The following embodiment refers to an instrument guide insert that is
used with the
instrument guide device 125 in place of the multi-faceted block (discussed
above). The instrument
guide insert can be positioned over the instrument guide device 125 and
pressed into the first
aperture, which may make a snapping noise when inserted. Next, the instrument
guide device 125
can be attached to an instrument guide bracket that contains holes that the
one or more protrusions
are sized to fit in. Then, ultrasound probe bracket 122 can be attached to the
ultrasound probe 121,
for example, by aligning the ultrasound probe bracket 122 with the ultrasound
probe 121 and
pushing upwards until a clicking/snapping noise is audible and/or a tactile
cue is felt. Additionally
or alternatively, the ultrasound probe 121 can be used to assemble the
ultrasound probe bracket
122 in a pivoting motion. After attachment, an ultrasound probe cover can be
placed over the
ultrasound probe bracket 122 and the ultrasound probe 121. Then, the assembled
instrument guide
device 125 can be attached to the ultrasound probe bracket 122 over the
ultrasound probe cover to
form a sterile barrier. hi some examples, the instalment guide device 125 can
attach to the
ultrasound probe bracket 122 via a magnetic attachment, an adhesive
attachment, a hook-and-loop
strips attachment, and/or the like.
[0087] Referring to the instrument guide insert, the
instrument guide insert can include the one
or more protrusions and/or one or more features that align with the one or
more protrusions and/or
the one or more features on the instrument guide device 125 such that the
instrument guide insert
snaps into pre-defined rotational positions as it is rotated to select
apertures (e.g., a set of apertures)
for different instrument sizes. Also, the instrument guide insert can be
rotated one way to close
the second aperture between the instrument guide insert and the instrument
guide device 125, and
rotated another way to open the second aperture between the instrument guide
insert and the
instrument guide device 125, such that the first instrument (e.g., the needle)
can be removed from
the instrument guidance device 120 in a direction perpendicular to the first
instrument's central
axis. The instrument guide insert and/or the instrument guide device 125 can
include a button
CA 03139694 2021-11-26
WO 2020/264383
PCT/US2020/039938
and/or a lever that can be actuated to open and close the second aperture
created between the
instrument guide insert and instrument guide device 125.
[0088] The ultrasound probe bracket 122 can include top
portion 122A and bottom portion
122B (shown in FIG. 3B) that can be joined together (e.g., snapped into place)
to form the
ultrasound probe bracket 122. In some examples, the ultrasound probe bracket
122 can be opened
about a hinge, fit around the ultrasound probe 121, and then closed together
while maintaining
alignment. In other examples, the ultrasound probe bracket 122 can include a
pin snap fit or a
latch to join members of the ultrasound probe bracket 122. Thus, the
ultrasound probe bracket 122
may fit the geometry of various sized ultrasound probes. Further, the
ultrasound probe bracket
122 can be split into a plurality of pieces (e.g., halves) and/or can be
opened and/or closed around
the ultrasound probe 121.
[0089] FIG. 4 shows a timing diagram of a method 400 for
instrument guidance (e.g., using
system 100). Thus, the method 400 can be performed by the computing device
110, the instrument
guidance device 120, and the ultrasound device 130. Further, each of the
aforementioned devices
may be in communication with one another to perform the method 400.
[0090] At 402, the ultrasound device 130 generates imaging
data, i.e., an ultrasound image of
a portion of a person's body. Then, at 404, the ultrasound device 130 sends
the imaging data to
the computing device 110. Next, at 406, the instrument guidance device 120,
using the first sensor
123A, can determine an angle of the instrument guide device 125 by tracking a
magnet that is
included within the instrument guide device 125. The instrument guidance
device 120 then
generates, at 408, position data based on the angle of the instrument guide
device 125. At 410, the
instrument guidance device 120 sends the position data to the computing device
110. The
computing device can, at 412, compute the pixel distance, for example on the
display 116 or the
ultrasound device 130, corresponding to a physical metric in the ultrasound
image (e.g.,
centimeters) at the present imaging depth.
[0091] Next, at 414, the computing device 110 can compute
how the position data should be
displayed at the present imaging depth given the pixel distance determined at
412. At 416, the
computing device 110 can generate an image overlay that projects the position
data onto the
imaging data, which can be displayed by the computing device 110, at 418. At
420, the computing
device 110 can send the image overlay to the ultrasound device 130 (as shown)
and/or an external
device.

[0092] FIG. 5 illustrates a flow chart of a method 500 for
instrument guidance. The method
500 is written from the perspective of the computing device 110 that can
communicate with the
instrument guidance device 120, the ultrasound device 130, and/or an external
device. Using the
method 500 can allow the computing device 110 to provide real-time imaging of
both a patient's
body and an instrument in relation to the patient's body.
[0093] At 505, the computing device 110 can receive imaging
data from the ultrasound device
130. The computing device 110 can also receive position data from the
instrument guidance device
120, at 510. At 515, the computing device 110 can determine pixel distance on
the display
corresponding to a physical metric (e.g., centimeters) in the ultrasound image
at the present
imaging depth. At 520, the computing device 110 can map a physical space in
the imaging data
onto a virtual display based on the pixel distance. Then, at 525, the
computing device 110 can
generate an image overlay that maps the position data (e.g., position of the
needle and a trajectory
of the needle) over the imaging data, such that the position of the instrument
is shown in relation
to the portion of the body being viewed by the ultrasound device 130. At 530,
the computing
device 110 can display the image overlay.

system configurations, including personal computers, smartphones, tablets,
hand-held devices,
multi-processor systems, microprocessor-based or programmable consumer
electronics,
networked PCs, minicomputers, mainframe computers, and the like. Embodiments
of the claimed
devices, systems, and methods are practiced in distributed computing
environments where tasks
are performed by local and remote processing devices that are linked (either
by hardwired links,
wireless links, or by a combination of hardwired or wireless links) through a
communications
network. In a distributed computing environment, program modules may be
located in both local
and remote memory storage devices.
[00103] An exemplary system for implementing various aspects of the described
operations,
which is not illustrated, includes a computing device including a processing
unit, a system
memory, and a system bus that couples various system components including the
system memory
to the processing unit. The computer will typically include one or more data
storage devices for
reading data from and writing data to. The data storage devices provide
nonvolatile storage of
computer-executable instructions, data structures, program modules, and other
data for the
computer.
[00104] Computer program code that implements the functionality described
herein typically
comprises one or more program modules that may be stored on a data storage
device. This program
code, as is known to those skilled in the art, usually includes an operating
system, one or more
application programs, other program modules, and program data. A user may
enter commands
and information into the computer through keyboard, touch screen, pointing
device, a script
containing computer program code written in a scripting language or other
input devices (not
shown), such as a microphone, etc. These and other input devices are often
connected to the
processing unit through known electrical, optical, or wireless connections.
[00105] The computer that effects many aspects of the described processes will
typically
operate in a networked environment using logical connections to one or more
remote computers
or data sources, which are described further below. Remote computers may be
another personal
computer, a server, a router, a network PC, a peer device or other common
network node, and
typically include many or all of the elements described above relative to the
main computer system
in which the devices, systems, and methods are embodied. The logical
connections between
computers include a local area network (LAN), a wide area network (WAN),
virtual networks

PCT/US2020/039938
(WAN or LAN), and wireless LANs (WLAN) that are presented here by way of
example and not
limitation. Such networking environments are conunonplace in office-wide or
enterprise-wide
computer networks, intranets, and the Internet.
[00106] When used in a LAN or WLAN networking environment, a computer system
implementing aspects of the devices, systems, and methods is connected to the
local network
through a network interface or adapter. When used in a WAN or WLAN networking
environment,
the computer may include a modem, a wireless link, or other mechanisms for
establishing
communications over the wide area network, such as the Internet. In a
networked environment,
program modules depicted relative to the computer, or portions thereof, may be
stored in a remote
data storage device. It will be appreciated that the network connections
described or shown are
exemplary and other mechanisms of establishing communications over wide area
networks or the
Internet may be used.
[00107] While various aspects have been described in the context of a
preferred embodiment,
additional aspects, features, and processes of the claimed devices, systems,
and methods will be
readily discernible from the description herein, by those of ordinary skill in
the art. Many
embodiments and adaptations of the disclosure and claimed devices, systems,
and methods other
than those herein described, as well as many variations, modifications, and
equivalent
arrangements and processes, will be apparent from or reasonably suggested by
the disclosure and
the foregoing description thereof, without departing from the substance or
scope of the claims.
Furthermore, any sequence(s) and/or temporal order of steps of various
processes described and
claimed herein are those considered to be the best mode contemplated for
carrying out the claimed
devices, systems, and methods. It should also be understood that, although
steps of various
processes may be shown and described as being in a preferred sequence or
temporal order, the
steps of any such processes are not limited to being carried out in any
particular sequence or order,
absent a specific indication of such to achieve a particular intended result.
In most cases, the steps
of such processes may be carried out in a variety of different sequences and
orders, while still
falling within the scope of the claimed devices, systems, and methods. In
addition, some steps
may be carried out simultaneously, contemporaneously, or in synchronization
with other steps.
[00108] The embodiments were chosen and described in order to explain the
principles of the
claimed devices, systems, and methods and their practical application so as to
enable others skilled

embodiments and with various
modifications as are suited to the particular use contemplated. Alternative
embodiments will
become apparent to those skilled in the art to which the claimed devices,
systems, and methods
pertain without departing from their spirit and scope. Accordingly, the scope
of the claimed
devices, systems, and methods is defined by the appended claims rather than
the foregoing
description and the exemplary embodiments described therein.
