Abstract

A medical instrument with a hollow shaft having at its proximal end a handle consisting of at least two gripping members and at its distal end a tool consisting of at lest two jaw members, where at least one jaw member of the tool is adjustable in relation to the at least one other jaw member of the tool for purposes of opening and closing by means of one rotatably shaped gripping member of the handle, and the at least one adjustable jaw member and the corresponding gripping member of the handle that serves to adjust the jaw member are connected to one another by means of two push-pull rods. In order to create a medical instrument that ensures a constantly sufficient transmission of power, it is proposed with the invention that the two push/pull rods are secured on contact points at intervals from one another above and below the pivot point of the adjustable jaw member on this jaw member in such a way that two straight lines each extending from the pivot point through one of the contact points form an angle (alpha+beta) of 110 to 160 degrees.
