摘要：
Various embodiments are directed to a surgical instrument comprising, a shaft, and an end effector. The shaft may be coupled to the handle and may extend distally along an longitudinal axis. The end effector may be positioned at a distal end of the shaft and may comprise first and second jaw members, a reciprocating member, a shuttle and at least one cam pin. The first and second jaw members may define first and second longitudinal slots and first and second cam slots and may be pivotable towards one another about a pivot point. The reciprocating member may be translatable distally and proximally parallel to the longitudinal axis and through the first and second longitudinal slots. A distal portion of the reciprocating member may define a blade. The shuttle may be translatable distally and proximally parallel to the longitudinal axis. The cam pin may be coupled to the shuttle and positioned within the first cam slot and the second cam slots.
