BLADE DEPLOYMENT MECHANISMS FOR SURGICAL FORCEPS

摘要

A forceps, comprising:
a first shaft member having a jaw member at a distal end thereof;
a second shaft member having a jaw member at a distal end thereof,
the first and second shaft members pivotally coupled to each other about a pivot to move the jaw members between an open position and a closed position;
a trigger disposed on the first shaft member;
a blade operatively coupled to the trigger such that rotation of the trigger translates the blade distally;
an interference member configured to prevent distal translation of the blade when the jaw members are in the open position; and
a protrusion disposed on the second shaft member and configured to move the interference member to permit distal translation of the blade when the jaw members are in the closed position.
