Forceps suitable for gripping body tissue or organs including a pair of jaws the gripping force of which can be adjusted. The forceps include an operating rod providing with axially spaced angularly offset cams which are selectively engagable by rotating the control rod with longitudinally slidable link assemblies separated by compression springs of differing stiffnesses. Rotation of the control rod to a particular angular position determines whether no spring or one or more springs are connected in series to determine the gripping force exerted by the forceps when the control rod is axially displaced. A control rod actuating lever is locked in position by means of a locking device.
