Abstract

A bipolar medical instrument has a shaft and two jaw parts arranged at the distal end thereof. An axially movable force transmission element is disposed with the shaft and is surrounded by an isolating element. The isolating element is connected to at least one of the two jaw parts in an articulated manner. The two jaw parts are electrically isolated from one another and each provides an electrode to which high frequency current can be applied. A first electrical supply line is formed along the shaft via an electrically conductive first contact element to one of the two jaw parts. A second electrical supply line is formed along the axially movable force transmission element via an electrically conductive second contact element to the other of the two jaw parts. The first contact element is fixed at the isolating element surrounding the distal end area of the force transmission element.
