Surgical instrument with actuator spring arm
First Claim
1. A handle assembly for use with a surgical instrument having an operative distal end portion comprising:
- a housing;
a drive element disposed at least partially within the housing and being longitudinally translatable with respect to the housing;
an actuator disposed in mechanical cooperation with the housing;
a spring arm disposed at least partially within the housing; and
a biasing element, a first portion of the biasing element coupled with the actuator, and a second portion of the biasing element coupled with the spring arm, wherein movement of the actuator translates the drive element distally from a proximal position to a distal position such that a portion of the drive element is in contact with the spring arm with the drive element in the proximal position and the drive element is spaced from the spring arm with the drive element in the distal position.

Abstract
A handle assembly for use with a surgical instrument having an operative distal end portion is disclosed. The handle assembly includes a housing, a drive element, an actuator, a spring arm, and a biasing element. The drive element is disposed at least partially within the housing and is longitudinally translatable with respect to the housing. The actuator is disposed in mechanical cooperation with the housing. The spring arm is disposed at least partially within the housing. The biasing element is for biasing the actuator. A first portion of the biasing element is disposed in mechanical cooperation with the actuator and a second portion of the biasing element is disposed in mechanical corporation with the spring arm. At least a partial actuation of the actuator distally translates the drive element from a proximal position where a portion of the drive element is in contact with the spring arm to a distal position where the drive element is not in contact with the spring arm.

10. A surgical instrument comprising:
-
a handle assembly; an endoscopic portion extending distally from the handle assembly; and an end effector disposed adjacent a distal end of the endoscopic portion and including a first jaw member and a second jaw member, the first jaw member being movable with respect to the second jaw member between an open position and an approximated position; wherein the handle assembly includes; a housing; a longitudinally translatable drive element; an actuator; a spring arm; and a biasing element , a first portion of the biasing element coupled with the actuator, and a second portion of the biasing element coupled with the spring arm, wherein at least a partial actuation of the actuator translates the drive element distally from a proximal position to a distal position such that a longitudinal surface of the drive element is in contact with the spring arm with the drive element in the proximal position and a proximal face of the drive element is in contact with the spring arm with the drive element in the distal position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
