Title (EN) SURGICAL INSTRUMENT
(FR) INSTRUMENT CHIRURGICAL
Abstract:
(EN) The invention relates to an instrument for surgery, in particular minimally invasive surgery. The instrument comprises means for feeding back a force which is exerted on the working element of the instrument to the operating element. These means comprise at least a first force sensor for measuring the force which is exerted on the working element, a control unit and a first actuator. On the basis of a signal which originates from the first force sensor, the control unit controls at least the first actuator in order to control the operating element. Furthermore, the means preferably comprise a first position sensor for measuring a position of the working element with respect to the frame. The control unit advantageously determines an impedance which the working element is subject to as a result of the presence of a tissue or the like, on the basis of which impedance the control unit controls at least the first actuator.
(FR) L'invention concerne un instrument utilisé pour des opérations chirurgicales, en particulier des opérations chirurgicales avec effraction minimale. Ledit instrument comprend des moyens servant à renvoyer la force qui est exercée sur l'élément de travail de l'instrument à l'élément d'actionnement. Ces moyens comprennent au moins un capteur de force, qui sert à mesurer la force qui est exercée sur l'élément de travail, une unité de commande et un premier actionneur. Sur la base d'un signal partant du premier capteur de force, l'unité de commande commande au moins le premier actionneur afin de commander l'élément d'actionnement. En outre, lesdits moyens comprennent, de préférence, un premier capteur de position, servant à déterminer la position de l'élément de travail par rapport à la carcasse. L'unité de commande détermine, de façon avantageuse, l'impédance à laquelle l'élément de travail est soumis en raison de la présence d'un tissu ou d'une substance analogue, et, sur la base de cette impédance, elle commande au moins le premier actionneur.
