The invention relates to an instrument for the
manipulation of fine structures, said instrument
detecting hand tremor and compensating for this hand
tremor by effecting counter-movements of the working tip.
The main area of application will probably lie in the
field of microsurgery, since the operations performed in
said field can be made difficult by the hand tremor of
the operating surgeon. Here, the tremor is detected by
movement sensors, by repeated analysis of the position of
the handheld part (1) of the instrument, or by deriving
electromyographie signals from the forearm of the
operator. Intentional and unintentional movements are
differentiated from one another on the basis of one or
more criteria, such as movement amplitude, speed,
frequency and direction. To compensate for undesired
movements, signals are sent to an arrangement of
actuators (3) which cause deflections of the movable part
(4) of the instrument, which deflections at the tip of
the instrument compensate for the hand tremor. When the
instrument is used as a needle holder in surgery, the
actuators (3) can also be controlled by push button in
such a way that, by oscillations, they facilitate the
penetration of the suture needle into the area being
worked on.
L'invention concerne un instrument destiné à la manipulation de fines structures, sensible au tremblement de la main et le compensant par des mouvements opposés de la pointe de l'outil. Le principal domaine d'application de l'invention est la microchirurgie, du fait que les activités développées dans ce domaine peuvent être aggravées par le tremblement de la main de l'opérateur. La détection du tremblement de la main s'effectue par des détecteurs de mouvement, par analyse répétée de la position de la partie (1) de l'instrument tenue par la main, ou par dérivation de signaux électromyographiques de l'avant-bras de l'opérateur. Des mouvements, intentionnelle ou non, sont différenciés au moyen d'un ou plusieurs critères tels que l'amplitude, la vitesse, la fréquence et la direction du mouvement. Pour compenser des mouvements indésirables, des signaux sont envoyés à un dispositif d'acteurs (3) provoquant, sur la partie mobile (4) de l'instrument, des déviations compensant, à la pointe de l'outil, le tremblement de la main. Lorsque l'instrument est utilisé comme porte-aiguilles en chirurgie, les acteurs (3) peuvent être également commandés par pression sur un bouton, de manière à faciliter, par oscillation, la pénétration des aiguilles à coudre dans l'objet à traiter.
