Abstract
A handle assembly for use with a surgical instrument includes a housing defining a contact wall, a movable handle, a plunger, a linkage, and a feedback mechanism. The plunger is disposed at least partially within the housing and defines a longitudinal axis. The linkage interconnects the movable handle with the plunger such that actuation of the movable handle results in longitudinal translation of the plunger relative to the housing. The feedback mechanism is configured to provide audible feedback to a user, and includes an indicator snap wire and a track defined by a wall of the housing. The snap wire is configured to move along the track in response to longitudinal translation of the plunger. The snap wire is configured to engage the contact wall of the housing to create a sound that is audible to a user when the movable handle has been actuated a predetermined amount.
