Abstract

An ultrasonic surgical assembly includes a disposable ultrasonic waveguide, a reusable exterior body, and a cordless ultrasonic-movement-generation assembly removably disposed in the body and operable to generate ultrasonic movement of the waveguide when connected thereto. The assembly also includes a reusable and rechargeable battery disposed in the body, a disposable handle having both a waveguide attachment dock exposed to the environment and operably connecting the waveguide thereto and an aseptically sealable assembly dock exposed to the environment and shaped to connect the waveguide in the attachment dock to the assembly through the handle when the assembly is disposed in the assembly dock. The assembly further includes a disposable compartment door that is movably connected to the handle to selectively expose the assembly dock to the environment and has an open position, permitting entry and removal of the assembly respectively into and from the assembly dock, and a closed position, aseptically sealing the assembly dock from the environment.
