High frequency surgical instrument
First Claim
1. A high frequency surgical instrument comprising a handling part that has a guide channel that is open at at least one end and a holding element that is axially displaceably guided therein and on which a high frequency voltage acts, with the holding element being axially displaceable by means of an actuating part axially displaceable with respect to the handling part and being electrically conductively connected at its free connecting end to a preferably elastic cutting loop in such a way that, through axial adjustment of the actuating part, the cutting loop can be drawn to a varying degree into the guide channel, or into a tube which continues it outwardly, or can be pushed out of the guide channel, or out of the tube continuing it outwardly, whereby the loop size can be changed,wherein the two of the cutting loop are led to a common base which is in turn releasably connectable to a shaft that is guided in the guide channel or tube and forms the holding element and is so dimensioned that it is displaceable with the shaft within at least one of the guide channel and the tube, andwherein the shaft can be displaced forwardly in at least one of the guide channel and the tube to such an extent that its front connecting end is located adjacent to the front end of the guide channel or tube, respectively, such that the base can be either released from the connection end or connected to it.

Abstract
The invention relates to a high frequency surgical instrument comprising a handling part (11) which has a guide channel (12) which is open at at least one end and a holding element (13) which is axially displaceably guided therein and on which a high frequency voltage acts. The holding element (13) is axially displaceable by means of an actuating part (14) axially displaceable relative to the handling part (11) and is electrically conductively connected at its free end to a preferably elastic cutting loop (15) in such a way that, through axial adjustment of the actuating part (14), the cutting loop (15) can be drawn to a greater or lesser degree into the guide channel (12), or into a tube (16) which continues it outwardly, or can be pushed out of the guide channel (12), or out of the tube (16) continuing it outwardly, whereby the loop size can be changed. The design is such that the two limbs (15'"'"', 15") of the cutting loop (15) are releasably secured to a shaft (13) which is guided in the guide channel (12) or tube (16) and forms the holding element.

wherein the two of the cutting loop are led to a common base which is in turn releasably connectable to a shaft that is guided in the guide channel or tube and forms the holding element and is so dimensioned that it is displaceable with the shaft within at least one of the guide channel and the tube, and wherein the shaft can be displaced forwardly in at least one of the guide channel and the tube to such an extent that its front connecting end is located adjacent to the front end of the guide channel or tube, respectively, such that the base can be either released from the connection end or connected to it.
