Abstract:
An electrosurgical forceps includes first and second shafts configured to rotate about a pivot to move jaw members between an open position and a closed position. A knife deployment mechanism is operably coupled to a knife and is configured to move the knife between a retracted position and an extended position. A knife lockout is configured to move between a first position wherein the jaw members are in the open position and movement of the knife from the retracted position to the extended position is prevented, a second position wherein the jaw members are in the closed position and movement of the knife from the retracted position to the extended position is permitted, and a third position wherein the jaw members are in the closed position and movement of the knife from the retracted position to the extended position is prevented.
