Abstract
A forceps that includes a housing, a cutting assembly, and an actuator. The housing has a shaft attached thereto that extends therefrom and is configured to support a pair of jaw members at a distal end thereof. The jaw members are movable to grasp tissue therebetween. The cutting assembly includes a spring element that has proximal and distal ends. The proximal end of the spring element is fixed to a boss disposed within the housing and the distal end of the spring element includes a cutting edge. The spring element is coiled at a proximal end thereof to create a spring bias against the boss. The actuator is operably coupled to the spring element and is configured to selectively advance the cutting edge of the spring element into the jaw members against the spring bias to sever tissue disposed therebetween.
