Multifunctional instrument for use in microinvasive surgery
First Claim
1. Multifunctional instrument for microinvasive surgery having an operator hand grip (10), a multi-lumen tube (14) attached to the operator hand grip, at least two guide channels (16, 18, 20) formed in parallel in the tube, and surgical instruments (22, 24, 26) which are displaceably and rotatably mounted in the guide channels and comprise a shaft (220, 240, 260), on whose distal end is disposed in each case a surgical working element, wherein the instruments (22, 24, 26) can be displaced between a non-operative position, in which the respective working element is retracted into the tube, and a working position, in which the respective working element projects on the distal end of the tube, characterized in that the instruments (22, 24, 26) can be displaced into and out of the working position by means of a motor, at least one of the instruments (22, 24, 26) can be rotated in its working position by means of a motor, and an electronic control is provided to control at least the motor-driven displacement movements and rotational movements, wherein the tube (14) comprises two guide channels (16, 18) having a first diameter and one guide channel (20) having a second diameter which is larger than the first diameter, wherein the tube (14) further comprises at least one additional channel (70,72) which serves as a suction or rinsing channel, and wherein the at least one additional channels (70, 72) is formed adjacent to the guide channel (18) having the larger diameter.

Abstract
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.
