Abstract

A forceps includes a pair of jaw members movable relative to one another, one of the jaw members defining a blade channel therein configured to house a cutting mechanism. The cutting mechanism includes: a blade having camming slots defined along a length thereof and one or more blade springs operably associated therewith configured to bias the blade within the blade channel; and a blade cam including camming surfaces configured to operably engage the corresponding camming slots of the blade. The blade cam includes a proximal end operably coupled to an actuation rod configured to move the blade cam upon movement thereof. The actuation rod, upon movement thereof, moves the camming surfaces of the blade cam into engagement against the camming slots forcing the blade into the blade channel against the bias of the biasing spring to cut tissue therebetween.
