A surgical instrument has an ultrasonic blade that connects to a distal end of an ultrasonic waveguide. A clamp arm assembly is moveable from an opened position for receiving a tissue, toward a closed position for clamping the tissue. A clamp arm actuator connected to the clamp arm assembly directs the clamp arm assembly from the opened position toward the closed position. An outer sheath surrounds at least a portion of the ultrasonic waveguide. The outer sheath includes a cover removably received against a sheath body, and a sheath securement feature able to detachably couple the cover to the sheath body such that the cover can be detached from the sheath body for accessing the ultrasonic waveguide within the outer sheath.

Surgical instrument with removable portion to facilitate cleaning

A surgical instrument has a first modular assembly and a second modular assembly. The first modular assembly has a body, an ultrasonic waveguide, an ultrasonic blade connected to a distal end of the ultrasonic waveguide, and a coupling member that movably couples with the body. The second modular assembly has a clamp arm assembly with a first pivot coupling, a clamp pad assembly with a second pivot coupling, and a distal outer sheath that selectively couples to the body of the first modular assembly via the coupling member. The distal outer sheath has an interior surface that houses a portion of the ultrasonic waveguide, and this interior surface also houses the first pivot coupling and the second pivot coupling.
