Vessel sealing instrument with stepped jaw |
摘要 |
A vessel sealer has a stepped jaw that allows the jaw to have an overall shape and a width that provides desired strength, shape, and functionality while permitting a smaller raised portion to apply the sealing pressure. The smaller area applying the sealing pressure allows an actuating mechanism to apply a clinically desired sealing pressure without exceeding the force or torque limitations of the actuating mechanism and can limit thermal spread during a sealing procedure. |
