Abstract: A surgical instrument comprising two jaw portions, at least one of which is rotatably mounted via an axis of rotation at a distal end of a shaft and is connected via a traction cable or a push rod to a gripping portion at the proximal end of the shaft, wherein the jaw formed by the jaw portions is held in an open or closed position by means of a suspension when the instrument is at rest.

Abstract: A coagulation forceps with a tubular shaft and with two forceps limbs and, which can both be movable or of which one is fixed, are uncovered on the gripping surfaces that face one another and serve for gripping tissue to be treated. At the distal ends, they have end surfaces, which contact a common plane, and are insulated on their outer sides that face away from one another, and provision is made for current connections for connection to a radiofrequency generator or to a current source for bipolar coagulation. Here, not only the gripping surfaces, but also the distal end surfaces of the forceps limbs and are uncovered and these uncovered end surfaces can be connected to uncovered outer surfaces of the forceps limbs and continuing said end surfaces such that tissue contacted by the two end surfaces and/or the outer surfaces can also be coagulated in a bipolar manner.

Abstract: A high-voltage system has an insulation-gas filled metallic encapsulation which surrounds active parts to which voltage is applied. A first protective coating (3) is provided on the internal surface of the encapsulation, as it is on the external surface of the active parts. As a result, a high-voltage system is provided in which a reduction of the dielectric strength of the insulating gas paths cannot occur as a result of freely mobile particles (5). This is achieved by covering the first protective coating (3) at least partially with a second protective coating (4).
