Medical instrument for dissecting tissue
First Claim
1. A medical instrument for dissecting tissue in the human or animal body, comprising:
- an elongated shaft having a distal end;
two jaw parts at said distal end of said shaft, said two jaw parts being movable relative to one another and configured to coact for dissecting said tissue, at least one of said two jaw parts being configured as an electrode which can be impinged upon by high-frequency current, wherein a further electrode which can be impinged upon by a high-frequency current is provided which can be optionally displaced from a retracted proximal position into a distal position adjacent to said two jaw parts in which position said further electrode forms in coaction with said at least one jaw part configured as an electrode one pole of an electrode arrangement for bipolar coagulation of said tissue.

Abstract
A medical instrument for dissecting tissue in the human or animal body has an elongated shaft and, at a distal end of said shaft, two jaw parts that are movable relative to one another and that coact for dissecting tissue, at least one of said jaw parts being configured as an electrode which can be impinged upon by high-frequency current. A further electrode that can be impinged upon by high-frequency current is provided, and can be displaced optionally from a retracted proximal position into a distal position adjacent to said jaw parts in which position it forms, in coaction with said at least one jaw part configured as an electrode, one pole of an electrode arrangement for bipollar coagulation of tissue
