CA 02701514 2015-11-25
A Sleeve Type Fixing Method and Device for Anastomosis for Tubular Organs such
as intestines, stomach, esophagus etc.
Field of the invention
The present invention relates to an anastomosis method and device for tubular
organs such as intestines or stomach etc., particularly to a sleeve type
fixing method
and device for anastomosis such as for intestines, stomach, esophagus and
gallbladder
etc..
Background of the invention
Operations of intestines and gall blade etc. are common surgery operations,
especially after the total stomach removal, the intestines and esophagus must
be
anastommosis, but after anastomosis by existing anastomosis devices, it often
happens
complication such as leakage, anastomotic stenosis, reflux, hard food passing,
and the
existing anastomosis device has high cost.
Tubular type surgical staplers used in the art (such as CDH25TM anastomat,
Johnson & Johnson) is to evert the distal and proximal intestines and secured
them by
two row metal pins, after healed, a constriction ring without flexible
function is
formed, thus case complication such as leakage, anastomotic stenosis, reflux,
hard
food passing etc. after healing.
An elastic ring adapter for used in esophagus gastric-chamber, disclosed in a
china
invention with the publication number CNI036898, is particularly suitable for
use in
esophagogastroanastomotic operation after removal of esophageal and cardiac
cancers.
The applicator of the present invention has two applications: CN10132714 and
CN101243987, which provide well devices for intestines anastomosis, without
intestinal anastomotic leakage, anastomotic stenosis and foreign body residue
at the
anastomotic and with few reflux, smooth passing of the holding substance and
low
medical service cost, but the operation is complex and need long time for
surgery, and
the anastomosis is not well enough.

Summary of the invention
The object of the present invention is to provide a method and device for
anastomosis such as for intestines, stomach, esophagus and gallbladder, which
has
simple structure, simple operation and well fixation.
A sleeve type fixing method and device for anastomosis for tubular organs such
as for intestines, stomach, esophagus etc., comprises an inner ring and an
outer ring,
wherein said outer ring is made of elastic material, two intestines ends are
respectively sewed to said outer ring and inner ring, and fixed to the outside
of the
rings, both the outer ring and the intestine fixed on said outer ring are
overturned so
that the intestine is connected to the inside of the outer ring, the outer
ring and inner
ring and the adventitia of the intestines fixed on the rings are clamped
together.
Further, the upper portion of said ring is used for anastomose, the middle
portion
is used for connecting, and the lower portion is used for insertion, the
diameter of the
connecting portion is smaller than the insertion portion and anastomose
portion, the
outer ring is made of elastic material, the inside of the lower portion of the
outer ring
has an inwardly protruding ring, said protruding ring is clamp to the
connecting
portion of the inner ring.
Said insertion portion of said inner ring is provided with axial grooves so as
to
narrow the diameter of the insertion portion.
The bottom of the insertion portion is provided with barbs to prevent the
outer
ring to be separated.
Said insertion portion of the inner ring is provided with a flange around the
upper portion.
The sleeve type method for anastomosis for the intestines of the present
invention
is achieved by an anastomosis device which comprises an inner ring and an
outer
ring,the upper portion is anastomosis portion, the middle portion is
connecting portion
and the lower portion is insertion portion, wherein the diameter of the
connecting
portion is smaller than the insertion portion and anastomosis portion, and
said outer

CA 02701514 2010-04-23
ring is made of elastic material, the inside of the lower portion of the outer
ring has an
inwardly protruding ring, said protruding ring is clamp to the connecting
portion of
the inner ring; in operation, firstly one intestine is sleeved on the flange
of the
anastomosis portion of said inner ring and fixed, and overturn the outer ring
so as to
let the lower edge to overturn, then another intestine is sleeved on the outer
ring and is
fixed, then overturn both the outer ring and the intestine so that the
intestine is
connected in the inner edge of the outer ring, finally insert said inner ring,
the two
intestines are overlapped on the anastomosis portion of the inner ring and
outer ring.
The present invention is to fix the intestines to the outer ring, let the
intestine and
the outer ring to overturn inwardly to let the intestine to fixed in the inner
side of the
outer ring by the elastic material and structure of the outer ring, so as to
connect to
another intestine fixed on the inner ring, this operation is simple and has
well effect.
And is fit for anastomosis between intestines, intestine and stomach,
esophagus and
intestine, esophagus and stomach, bile duct and intestine etc..

Detailed description of the preferred embodiment
The above-mentioned and other features and advantages of this invention, and
the
manner of attaining them, will become more apparent and the invention itself
will be
better understood by reference to the following description of embodiments of
the
invention taken in conjunction with the accompanying drawings, wherein:
Embodiment 1
Referring to FIG1 to FIG.3, the anastomosis device comprises an inner ring 1
and an outer ring 2, the upper portion of the inner ring is an anastomosis
portion 13,
the middle portion is a connection portion 12 and the lower portion is an
insertion
portion 11, the diameter of the connecting portion 12 is smaller than the
insertion
portion 11 and the anastomosis portion 13, the outer ring 2 is made of elastic
material,
and the side wall of the outer ring 2 is provided with thread holes 21 set
according to
the sewing position of the intestines, the bottom of the outer ring is set a
protruded
ring 21, the protruded ring 21 is clamp to the connecting portion 12 of the
inner ring,
the lower edge of the connecting portion of the inner ring is formed a circle
or several
flanges 121. The insertion portion 11 of said inner ring has axial grooves
112, thus the
diameter of the insertion portion has a narrowed variable. The insertion
portion 11 has
barbs 111 which can prevent the outer ring to be separated.
The inner ring 1 can be made by food-grade hard plastic, and the height of the
inner
ring 1 is between 3-6mm.
4

CA 02701514 2010-04-23
The outer ring 2 can be made by nitrile-butadiene rubber, the height of the
outer
ring is between 3-6mm.
Referring to FIG.4 to FIG.8, in operation, firstly, an intestine 3 is sleeved
on the
outside of the anastomosis portion of the inner ring 1, the intestine can be
sewed in
the grooves of the connecting portion 12 of the inner ring by absorbable
thread 5, as
shown in 8-1, 8-2, overturn the outer ring 2 inwardly and let the inward
flange 21 to
be outward, then another intestine 4 is sleeved on the outer ring 2 and is
fixed by a
absorbable thread, then overturn both the outer ring 2 and fixed intestine 4
to let the
connecting end of the intestine 6 in the inner side of the outer ring 2,
finally insert the
inner ring 1, then two intestines are overlapped in the anastomosis portion,
the inner
ring 1, outer ring 2 and two intestines 3,4 are formed stable fixation
structure, the
serous membrane of the intestines are contacted with each other, and the width
of the
contacting area is about 0.4-0.5 cm. usually the inner ring 1 and outer ring 2
will be
automatically detached from the intestines in about 10 days, and discharged
out from
the anus, the intestine and the esophagus is healed in sleeve type, the
healing is
without intestinal anastomotic leakage, anastomotic stenosis and foreign body
residue
at the anastomotic and with few reflux, smooth passing of the holding
substance and
low medical service cost, .
Embodiment 2
In this embodiment, the outer ring is different from the embodiment 1, as is
shown in FIG10 and FIG11, the outer ring 7 is extended out a ring 71 in the
inner
side of the outer ring 7, the inner ring 1 has the same structure as
embodiment 1, so in
operation, the inner ring do not need to be overturned, the intestines are
sewed in the
outer ring 7 and then overturned, and the other process is the same as
embodiment 1.
