US Patent 7513897 Coagulation tweezers with limiter opening

Coagulation tweezers (1) provided with two tweezers legs (2) and (3), with their mutual pivoting apart from each other being limited by a stop element (6) and a counter stop element (7). Here, the protrusion or head (10) of the stop element (6), during the opening or closing the legs (2) and (3) of the tweezers, is movable inside the counter stop element (7) in reference thereto, and is spaced apart a distance in the radial direction during its relative displacement or pivotal path movement in reference to the interior longitudinal cavity (12) of the counter stop element (7) so that during normal pivotal motions of the tweezers no friction develops by these stop elements.
