Abstract: The invention relates to a forceps with two branches which can be pushed resiliently against each other, are connected to each other at one end by means of a connection section and have a resilient section distally adjoining the connection section, a grip section distally adjoining the resilient section and forceps legs distally adjoining the grip section. In order to afford the possibility of matching the spring force of the forceps to different operational aims, provision is made according to the invention for a support apparatus which is arranged on a branch in the region between the connection section and the grip section or in the proximal region of the grip section, which support apparatus extends transversely between the branches in the direction of the other branch and which is adjustable in terms its spacing from the other branch.

Abstract: An instrument for endoscopic surgery, with a housing having a grip element and a shaft-receiving element, the grip element having a fixed grip part and a pivotable grip part, and the shaft-receiving element being intended to receive and lock the proximal end of a tubular shaft, with a tool at the distal end of the shaft, and with an actuation member extending through the shaft and being longitudinally movable therein, or with a slide piece acting on the actuation member. The actuation member engages in the shaft-receiving element of the housing and is coupled to the grip part mounted pivotably on the housing, so that a pivoting of the grip part causes a longitudinal movement of the actuation member and an actuation of the tool. The grip element of the housing is rotatable relative to the shaft-receiving element of the housing about a rotation axis extending perpendicular to the shaft.
