摘要： Pincers used in endoscope surgery, including a proximal terminal structure and a tube serving as the pincers' stem affixed to the proximal terminal structure. A stationary handle is affixed to the terminal structure. A displaceable handle rests on the stationary handle and is fitted along the tube axis with a swivel seat. A pincers head bears the pincers arms and is detachably and rotatably connected to the distal tube end. An axially displaceable rod drives the pincers arms and is affixed irrotationally to the pincers head. The rod crosses the tube and rests in the swivel seat. The rod is situated in the region of the rotational connection, and exhibits, at least over the engagement zone running the length of its axial displacement, a rotationally asymmetric cross-section. The slider rests in a transverse clearance of the tube, and is fitted with an elongated slot passing the rod. The slot freely passes the proximally situated tube segment exhibiting a maximum-diameter circular cross-section and enclosing the rod's engagement zone in irrotationally locking manner in a gripping zone, which is offset in the sliding direction.

摘要： A bipolar endoscopic instrument including a tubular stem having a distal end and a proximal end. The stem distal end supports two jaws that are pivotable relative to one another. The proximal end of the tubular stem has a bipolar hf plug inserted therein at an acute angle to a push/pull wire. The plug applies a bipolar output of a high-frequency (hf) voltage source into the inside of the instrument. The inserted end of the hf plug is shaped such that the plug contacts are axially insulated from each other and each plug contact touches an electrically conducting contact element inside the instrument which, in turn, is connected in electrically conducting manner to one of the two jaws. A unit is present inside the instrument and includes the two contact elements and an insulator electrically separating the contact elements. The hf plug engages the insulator while a particular plug contact touches a particular contact element.
