Abstract
A handle assembly for actuating an end effector includes a feedback mechanism for providing an audible and/or tactical response to indicate to the user that the handle assembly is fully actuated. The feedback mechanism may include a hammer member configured to strike a surface of the handle assembly to create the audible and/or tactical response.
Claims20
A handle assembly, comprising:
- a housing defining a longitudinal axis;
- a trigger operably coupled to the housing and movable to cause actuation of the handle assembly;
- a drive member movable within the housing from an initial position to an advanced position in response to actuation of the trigger;
- and
- a feedback mechanism in operable engagement with the trigger, the feedback mechanism including a torsion spring having a hammer portion, wherein upon complete actuation of the handle assembly the hammer portion of the torsion spring strikes a surface to create at least one of an audible or a tactile response.

A handle assembly, comprising:
- a housing defining a longitudinal axis;
- a trigger operably coupled to the housing and movable to cause actuation of the handle assembly;
- a drive member movable within the housing from an initial position to an advanced position in response to actuation of the trigger, the drive member including a ramp portion;
- and
- a feedback mechanism including a hammer member in selective engagement with the ramp portion of the drive member, wherein upon complete actuation of the handle assembly, the hammer member disengages from the ramp portion and strikes a first pin to create at least one of an audible or a tactile response.

A handle assembly, comprising:
- a housing defining a longitudinal axis;
- a trigger operably coupled to the housing and movable to cause actuation of the handle assembly;
- a drive member movable within the housing from an initial position to an advanced position in response to actuation of the trigger, the drive member including a ramp portion;
- and
- a feedback mechanism including first and second pins disposed within the housing, and a spring member secured to the drive member, wherein the spring member is configured to engage the first pin during the actuation of the handle assembly and disengage from the first pin upon complete actuation of the handle assembly.
