摘要:
A multifunctional instrument for use in microinvasive surgery includes an operator hand grip, a multi-lumen tube fastened on the operator hand grip, at least two guide channels coaxially configured inside the tube, and surgical instruments that are displaceably and rotationally disposed in the guide channels. The instrument also includes a shaft at whose distal end one surgical working element each is disposed. The instruments can be displaced between a rest position, in which the respective working element is retracted into the tube, and a working position, in which the respective working element projects from the distal end of the tube. The instruments can be displaced into and out of the working position by means of a motor and at least one of the instruments can be rotated in its working position by means of a motor. The instrument can be controlled by means of an electronic control that controls at least the motor-driven displacement motions and rotational motions of the surgical instruments and the tube.
