    Abstract: A surgical instrument includes 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.

    Abstract: A surgical instrument includes a pair of jaw members moveable between a spaced-apart and an approximated position. A drive bar is translatable between a distal and a proximal position for moving the jaw members between the spaced-apart and approximated positions. A lever is moveable between an initial position and an actuated position for translating the drive bar between the distal and proximal positions. A sleeve disposed about the drive bar includes an annular track having a substantially radial segment(s) and a substantially longitudinal segment(s). A collar interdisposed between the sleeve and the drive bar includes a stop member(s) extending radially outwardly therefrom. The stop member(s) is engaged within the track and is translatable from a first position, wherein the stop member is positioned within the longitudinal segment, to a second position, wherein the stop member is engaged within the radial segment, to lock the lever in the actuated position.

    Abstract: A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.
