The end of the clamps are equipped with a chamfer for the matching applying forceps. Due to this chamfer the clamp is held securely by the applying forceps, so that it can be used in every level of movement without danger. The clamp opens by applying pressure to the forceps, when the pressure is lessened it closes. Clamp applying forceps are available with or without lock. By applying light pressure the lock clicks shut and thus holds the vascular clamp in half-opened position. After application of the clamp, the lock is opened by light finger pressure.
