    摘要： A surgical instrument includes a shaft defining a longitudinal axis therethrough and having an end effector assembly disposed at a distal end thereof. The shaft includes first and second shaft components that are releasably engageable with one another. A drive sleeve is disposed within the shaft and is longitudinally translatable relative to the shaft to transition the end effector assembly between a first state and a second state. The drive sleeve includes first and second drive sleeve components that are releasably engageable with one another. A coupling mechanism includes one or more shaft cantilever springs configured to releasably engage the first and second shaft components to one another and one or more drive sleeve cantilever springs configured to releasably engage the first and second drive sleeve components to one another.

    摘要： A surgical instrument includes a handle coupled to a source of electrosurgical energy. A pair of opposed jaw members is operatively coupled to a distal end of the handle such that the jaw members selectively move between open and closed positions. A base supported on one of the jaw members includes a mechanical mating feature and an electrically conductive region in electrical communication with the source of electrosurgical energy. A selectively removable seal plate includes a complementarily engaging a mechanical mating feature and an electrically conductive region positioned to contact the electrically conductive region of the base when the mechanical mating features of the base and seal plate are engaged. The complimentarily-engaging mechanical mating features include a pair of spaced protrusions and a pair of spaced recesses open to opposing sides of the base or the seal plate such that the seal plate may be twisted onto the base.

    摘要： A surgical instrument includes an elongated shaft having a proximal structural member and a proximal drive member that is selectively movable with respect to the proximal structural member. A modular end effector is removably coupled to the elongated shaft, and has a distal structural member and a distal drive member that is operatively coupled to a pair of jaw members. A separable joint is defined between the elongated shaft and the end effector. The separable joint includes laterally prominent and laterally indented portions of each of the proximal and distal structural members and of each of the proximal and distal drive members. The structural members are interlocked to resist longitudinal separation and permit lateral separation. The drive members are movable relative to structural members to move the separable joint to a locked configuration wherein the drive members prohibit lateral separation of the structural members.

    摘要： A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members includes a jaw frame including an engagement recess defined on each lateral side thereof and a replaceable component configured for slidable positioning about the jaw frame. The replaceable component includes an outer jaw housing having an engagement tang disposed on each lateral side thereof. The engagement tangs are configured to engage the engagement recesses of the jaw frame upon slidable positioning of the replaceable component about the jaw frame to secure the replaceable component to the jaw frame. The replaceable component includes an electrically conductive tissue sealing plate engaged to the outer jaw housing to define a tissue sealing surface.

One or both of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members includes a jaw frame and a replaceable component engageable with the jaw frame. The replaceable component includes one or more engagement members configured to engage a corresponding engagement member(s) disposed on the jaw frame to secure the replaceable component to the jaw frame. The engagement member(s) is transitionable from a new state to a used state, wherein, in the used state, the engagement member(s) is incapable of reengaging the corresponding engagement member(s).
