ABSTRACT:
A coagulation clamp (1) has clamp jaws (4) and two projections (2bor2c, 2d) that impinge on these jaws directly or indirectly and that can be pivoted relative to one another on a common joint (2) with the aid of hand grips (3). The projections are insulated in the area of the joint and each connected directly or indirectly with a high-frequency terminal (HF). Here, the joint openings (6) are coated with an insulation that surrounds the joint axle (7) in the position of use, this insulation usefully being formed by a respective insulating sleeve (8). The joint axle (7) is made up of a sleeve (71) and an insert (72) that can be placed therein in telescoping fashion and that has a press-fit seating and that, on the side of sleeve (71) facing away from the insertion side, extends up to or into an opening (9a) of a termination (9) of this sleeve (71) and is fixedly connected with this sleeve termination (9), preferably being welded thereto. This results in a stable joint (2) that can absorb large forces. Because both the sleeve (71) and its insert (72) can protrude past the clamp jaw (4) externally with a respective stop or flange (12or13), lateral or shear forces can also be absorbed effectively.
