Abstract
The invention relates to an electrosurgical gripping instrument which includes a cutting section for cutting tissue without deformation. The cutting section can be deflected from an idle position for cutting purposes which brings it into contact with the tissue.
Claims17
An electrosurgical gripping instrument comprising:
- a first jaw and a second jaw, which can jointly perform a plier-like gripping movement, wherein the first jaw includes a first gripping surface that faces towards the second jaw and the second jaw includes a second gripping surface that faces towards the first jaw;
- a cutting wire that forms a conductive electrode, the cutting wire comprising:
- a cutting section with a first end and a second end, wherein the second end of the cutting section defines a distal-most end of the cutting wire and is rotatably fixated at a distal section of the first jaw via a hinge;
- and
- a pushing section;
- an operable tripping device;
- and
- a pushing device which, during operation of the tripping device, exerts a pushing force on the first end of the cutting section via the pushing section of the cutting wire, the pushing section being positioned between the first end of the cutting section and the pushing device, whereby the pushing force has at least one component in an axial direction,
- wherein:
- the cutting wire has an idle position in which the cutting section is arranged on a side of a plane between the first gripping surface and the second gripping surface, wherein the first jaw is on the same side of the plane, and
- the cutting section of the cutting wire laterally bends out in a direction transversal to the first gripping surface, and beyond the plane between the two gripping surfaces towards the second jaw when the tripping device is actuated.
