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.

Feedback mechanisms for handle assemblies

A handle assembly for actuating of a surgical end effector is provided. The handle assembly includes a friction reducing mechanism. The friction reducing mechanism may be mounted within a housing of the handle assembly and engage a drive member of the handle assembly. Alternatively, the friction reducing mechanism may be disposed on the drive member. The friction reducing mechanism instead or also includes a bearing member disposed between a trigger member and the housing of the handle assembly.
