TWO STAGE TRIGGER, CLAMP AND CUT BIPOLAR VESSEL SEALER

摘要

A surgical instrument includes a handle assembly and an end effector. The handle assembly includes a trigger, a push plate coupled to the trigger, wherein actuation of the trigger rotates the push plate, a clamp plate operably coupled to the push plate, wherein actuation of the trigger to a first rotation rotates the clamp plate, and a firing plate operably coupled to the push plate, wherein actuation of the trigger between the first rotation and a second rotation rotates the firing plate. The end effector includes a jaw assembly which includes a first jaw member and a second jaw member, wherein rotation of the clamp plate transitions the jaw assembly between an open configuration and an approximated configuration by moving at least one of the first jaw member and the second jaw member relative to the other one of the first jaw member and the second jaw member.

1. A surgical instrument, comprising:
a handle assembly comprising:
a trigger;a push plate coupled to the trigger, wherein actuation of the trigger rotates the push plate;a clamp plate operably coupled to the push plate, wherein actuation of the trigger to a first rotation rotates the clamp plate; anda firing plate operably coupled to the push plate, wherein actuation of the trigger between the first rotation and a second rotation rotates the firing plate; a shaft assembly comprising a proximal end and a distal end, wherein the shaft assembly is coupled to the handle assembly at the proximal end; and an end effector coupled to the distal end of the shaft assembly, the end effector comprising:
a jaw assembly, comprising:
a first jaw member; anda second jaw member, wherein rotation of the clamp plate transitions the jaw assembly between an open configuration and an approximated configuration by moving at least one of the first jaw member and the second jaw member relative to the other one of the first jaw member and the second jaw member; anda cutting member deployable in response to rotation of the firing plate.
