1. A handle assembly for use with a surgical instrument having an operative distal end portion, the handle assembly 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 for biasing the actuator, a first portion of the biasing element disposed in mechanical cooperation with the actuator and a second portion of the biasing element extending through an aperture in the spring arm, wherein movement of the actuator translates the drive element distally 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 spaced from the spring arm.

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. 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.

8. 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 from an open position to an approximated position, wherein the handle assembly includes; a housing; a longitudinally translatable drive element; an actuator; a spring arm; and a biasing element for biasing the actuator, a first portion of the biasing element disposed in mechanical cooperation with the actuator and a second portion of the biasing element extending through an aperture in the spring arm, wherein at least a partial actuation of the actuator translates the drive element distally from a proximal position where a lower surface of the drive element is in contact with the spring arm to a distal position where a proximal face of the drive element is in contact with the spring arm. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 18)

19. A handle assembly for use with a surgical instrument having an operative distal end portion, the handle assembly 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 for biasing the actuator, a first portion of the biasing element disposed in mechanical cooperation with the actuator and a second portion of the biasing element disposed in mechanical corporation with the spring arm, wherein movement of the actuator translates the drive element distally 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 spaced from the spring arm; wherein movement of the actuator from an actuated position to a non-actuated position translates the drive element distally from the proximal position where the portion of the drive element is in contact with the spring arm to the distal position where the drive element is spaced from the spring arm.

20. 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 from an open position to an approximated position, wherein the handle assembly includes; a housing; a longitudinally translatable drive element disposed at least partially within 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 for biasing the actuator, a first portion of the biasing element disposed in mechanical cooperation with the actuator and a second portion of the biasing element disposed in mechanical corporation with the spring arm, wherein at least a partial actuation of the actuator translates the drive element distally from a proximal position where a lower surface of the drive element is in contact with the spring arm to a distal position where a proximal face of the drive element is in contact with the spring arm; wherein movement of the actuator from an actuated position to a non-actuated position translates the drive element distally from the distal position to a further distal position where the drive element is spaced from the spring arm.
