Patent ID: 7431720

Claim:
An actuation mechanism, comprising: a handle assembly including at least a first user-operable portion; an elongated body extending distally from the handle assembly; a first actuation member carried within the elongated body and extending to a distal end of the elongated body; wherein the first actuation member is moveable in response to movement of the first user-operable portion; an electrical supply line extending from the handle assembly to the distal end of the elongated body; and a coupling at the distal end of the elongated body for releasably coupling the elongated body in turn to a clamping head and an electrically-energizable head; wherein, when the elongated body is coupled to the clamping head, the first actuation member controls clamping of the clamping head, and when the elongated body is coupled to the electrically-energizable head, the electrical supply line electrically energizes the electrically-energizable head.
