Two stage trigger, clamp and cut bipolar vessel sealer
First Claim
1. A surgical instrument, comprising:
- a handle assembly comprising;
a trigger actuatable to a first position and a second position following the first position;
a push plate coupled to the trigger, wherein the actuation of the trigger rotates the push plate;
a clamp plate operably coupled to the push plate, wherein the actuation of the trigger to the first position rotates the clamp plate; and
a firing plate operably coupled to the push plate, wherein the actuation of the trigger between the first position and the second position 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; and
a second jaw member, wherein the 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; and
a cutting member deployable in response to the rotation of the firing plate.

Abstract
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.
