ELECTROSURGICAL DEVICES

摘要

In various embodiments, a surgical instrument is disclosed. The surgical instrument comprises a handle assembly having a closure trigger, a closure actuator coupled to the closure trigger at a first pivot, and a closure spring. The closure actuator moves proximally on a longitudinal axis in response to actuation of the closure trigger. The closure spring applies a force vector to the closure spring tangential to the longitudinal axis. A shaft assembly is coupled to the handle assembly. An end effector is coupled to a distal end of the shaft assembly. The end effector comprises a jaw assembly comprising a first jaw member and a second jaw member. The first jaw member is pivotally moveable with respect to the second jaw member. At least one of the first and second jaw members are operatively coupled to the closure actuator.

1. A surgical instrument comprising:
a handle assembly comprising:
a closure trigger;a closure actuator coupled to the closure trigger at a first pivot, wherein the closure actuator moves proximally on a longitudinal axis in response to actuation of the closure trigger;a closure spring configured to apply a force to closure actuator at the first pivot, wherein the closure spring is compressed in response to movement of the closure trigger, and wherein a force vector of the force applied by the closure spring is tangential to the longitudinal axis; a shaft assembly coupled to the handle assembly; and an end effector coupled to a distal end of the shaft assembly, the end effector comprising:
a jaw assembly having a proximal end and a distal end, the jaw assembly comprising:
a first jaw member; anda second jaw member, wherein the first jaw member is pivotally moveable with respect to the second jaw member, and wherein the first jaw member is operatively coupled to the closure actuator.
