Abstract
The invention concerns an electrosurgical instrument comprising two articulated limbs, which can be actuated in the manner of a cutting or a clamping tool. The instrument further comprises opposing electrode parts with coagulating surfaces at the distal ends of the limbs for grasping a vessel or tissue and for conducting a coagulating current through the vessel or tissue in order to cause it to coagulate, as well as current-supplying devices for supplying the coagulating current to the electrode parts from a HF generator. In addition, the electrode parts each have at least one clamping region, such that clamped tissue is pretensioned between the electrode parts in order that a cutting procedure can be carried out on the pretensioned tissue by means of a cutting instrument.
Claims18
Electrosurgical instrument including
- two articulated limbs, which can be actuated in the manner of a cutting or clamping tool,
- electrode parts with coagulating surfaces positioned opposite each other at distal ends of the limbs for gripping tissue and adapted to pass for a coagulating current through said tissue to cause its coagulation,
- current supply devices adapted to supply said coagulating current to said the electrode parts from a HF generator, and wherein
- at least one clamping region defined by each of said electrode parts that is adapted to claim said tissue whereby said tissue is pretensioned between said electrode parts and in order that a cutting procedure can be carried out on said pretensioned tissue by means of a cutting instrument.
