A forceps, comprising:a first shaft (12a) having a jaw member (120) at a distal end thereof；a second shaft (12b) having a jaw member (110) at a distal end thereof, each of the jaw members including an electrically conductive sealing surface (112a, 112b), the first and second shafts pivotally coupled to each other about a pivot (65) such that the jaw members are movable between an open position and a closed position；a trigger (45) disposed on the first shaft；a knife (85) operatively coupled to the trigger such that actuation of the trigger translates the knife distally through a knife channel (115) extending at least partially through at least one of the jaw members；an anti-deployment link (47) configured to prevent distal translation of the knife when the jaw members are in the open position, wherein movement of the jaw members to the closed position moves the anti-deployment link to permit distal translation of the knife； anda switch (50) disposed on one of the first and second shafts and configured to be depressed when the jaw members are in the closed position to control a supply of electrosurgical energy from an electrosurgical energy source to each of the electrically conductive sealing surfaces.
