Electrosurgical instrument for coagulating tissue, has deformable unit arranged on branch or gripping device such that area of gripping device can be moved to actuate switching device when branches are closed and minimum distance is reached

摘要

The instrument has gripping devices in a proximal zone of branches (20, 21) or the instrument to merge the branches. Electrode parts grip tissues and conduct a high frequency current through the tissues. A spacing unit (80) forms a minimum distance between the parts. An elastically deformable unit (100) is arranged on one branch or gripping device such that an area of the gripping device can be moved in the proximal region to actuate a switching device when the branches are closed and the distance is reached. The unit (100) is made up of polyether ether ketone or plastic or spring steel.
