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.

The pivot element is likewise essentially made from biocompatible metal and attaches directly to the moving forceps leg. An insulating body electrically insulating the pivot element and the moving forceps leg from the fixed forceps leg is arranged on or fixed to the fixed forceps leg as a pivot support, on which the moving forceps leg is supported by the pivot element.

Abstract: In an electro-surgical instrument (1), two electrode surfaces (25, 27) are provided for a first electrode (15, 31, 32, 34, 36) having different sizes, each forming a pair of electrodes with electrode surfaces (26, 28) of a second electrode (14, 16, 33).

Here, the protrusion or head (10) of the stop element (6), during the opening or closing the legs (2) and (3) of the tweezers, is movable inside the counter stop element (7) in reference thereto, and is spaced apart a distance in the radial direction during its relative displacement or pivotal path movement in reference to the interior longitudinal cavity (12) of the counter stop element (7) so that during normal pivotal motions of the tweezers no friction develops by these stop elements.

Abstract: Bipolar scissors (1) with two curved shear blades (2, 3) are provided with insulation on each of the shear blades (2, 3), which is distributed on the two shear blades (2, 3) such that each of the shear blades (2, 3) is insulated only over a part of its length, however the insulation is continuous in this area, i.e. at each of the two shear blades (2, 3) only a single longitudinal area is coated in a lamellar and uninterrupted fashion with insulation (11, 12). The insulation (11, 12) of each of the shear blades (2) complements each other in the closed position of the scissors (11) such that the overall insulation essentially extends over the entire length of the two shear blades (2, 3). This way, each piece of the curved insulation follows the curvature of the shear blade, and in case of mounted insulating plates, there is little stress and the insulation can also withstand several autoclaving processes without separating from the shear blades (2, 3).
