The endoscopic instrument comprises two working parts provided at the distal end region of an elongate shank, of which at least one is pivotingly movable relative to the other, and is provided with handle at the proximal end region of the shank for actuating at least one of the working parts via an actuation rod running in the shank, wherein the working parts in the region of their pivoting mounting submit to a spring force for pressing these parts onto one another. For achieving an exact bearing force of the working parts on one another and an increased security against their damage during use of the instrument the shank at its distal end is provided with a fork-shaped holder with two resilient distal fork arms producing the pressing force onto the working parts, whose at least one fork arm comprises a receiver bore. The pivotingly movable working part is inserted in the intermediate space formed by the two fork arms and is provided with a projecting joint peg which pivotingly engages into the receiver bore of the allocated fork arm of the holder. |
