Abstract
An electrosurgical instrument for coagulating and/or cutting biological tissue which can be manufactured easily and economically and which allows a surgical intervention to be carried out easily and reliably The instrument includes two linked branches which can be moved toward one another, gripping devices at a proximal region of the branches or of the instrument for bringing the branches together, electrode parts at a distal region of the branches or of the instrument for grasping tissue and for conducting a high-frequency current through the tissue, current feed devices for feeding the high-frequency current to the electrode parts from a high-frequency generator, a switching device for activating the high-frequency current with the branches brought together, at least one spacing element to form a defined minimum spacing between the electrode parts, and at least one elastically deformable element, which is arranged at one of the branches or the gripping devices such that, on closing the branches and reaching the minimum spacing, at least one region of the gripping devices can be moved further in the proximal region for actuating the switching device. The instrument can also be carried out as a shaft instrument, wherein at least one electrode part is movable through a shaft in its extension direction.
