Surgical coagulation clamp, to pass current through tissue for coagulation, has conductive clamping pad surfaces with non-conductive projections bearing against facing pad surfaces between facing projections

摘要

The surgical coagulation clamp (1) has clamping pads (5,6) moving against each other on a hinge pivot (4), with non-conductive projections (12,13) to make a contact with the conductive surfaces (7,8) of the facing pads and between the facing projections. Limit stops (9,10) bear against each other when the pads are closed, to ensure that the pad surfaces are parallel with a gap between them. The projections are of ceramic or thermoplastic materials. The electrically conductive surfaces of the pads are through a metal filling in one or more recesses.
