ABSTRACT:
A bipolar surgical grasping instrument with two grasping arms that are electrically insulated from one another. The two arms are pivotally mounted at the end of a tubular shank, and are coaxially pivotable in opposite directions by toggle lever elements that are activated by a push-and-pull rod displaceable in the tubular shank. The push-and-pull rod and the toggle lever elements of the two arms consist of electrically conducting material and are electrically conductively connected to one another. The first arm is electrically conductively connected to it associated toggle lever elements. The second arm is connected to its associated toggle lever elements via an insulating part, and the second arm is electrically conductively connected via a pivot bearing to the tubular shank. The first arm is rotatably mounted on the tubular shank and electrically insulated from the second arm and from the tubular shank.
