    Abstract: An endoscopic instrument is provided and includes a housing including an elongated shaft assembly extending distally therefrom. The elongated shaft assembly includes inner and outer shaft members. The inner and outer shaft members are removably coupled to the housing and the outer shaft member is movable with respect to the inner shaft member. An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

    Abstract: A surgical instrument a reusable component and a disposable component selectively separable from and engagable with the reusable component. The disposable component includes an end effector and a mechanical actuator operable to induce mechanical movement of the end effector. The reusable component is configured for providing electrosurgical energy to the disposable component when engaged with the disposable component. A physical mating feature is configured to maintain engagement between the reusable and disposable components when the reusable and disposable components are engaged, and an electrical mating feature is configured to transmit electrical energy between the disposable and reusable components when the disposable and reusable components are engaged. All mechanical motion resulting from operation of the mechanical actuator may be contained within the disposable component.
