    Abstract: A shaft assembly of an apparatus for applying surgical clips to body tissue includes a pair of jaws movable between a spaced-apart position and an approximated position, an elongated spindle, a shaft, a slidable member, and a pusher bar fixed to the slidable member. The slidable member is movable through longitudinally-extending channels of the spindle and the shaft. The pusher bar is configured to load a distal-most surgical clip into the pair of jaws during distal movement of the slidable member, via distal movement of the spindle, and remain in a distally advanced position during approximation of the pair of jaws.

    IPC: A61B17/128

    Abstract: A handle assembly for use with a surgical instrument including a housing, a movable handle, a plunger, a first linkage, and a second linkage. The movable handle is pivotably mounted to the housing about a handle pin. The plunger is disposed at least partially within the housing. Distal translation of the plunger relative to the housing is configured to affect a function of the surgical instrument. The first linkage is disposed at least partially within the housing. A first portion of the first linkage is pivotable about the housing, and a second portion of the first linkage is slidable relative to the handle pin. The second linkage is disposed at least partially within the housing. A first portion of the second linkage is pivotable about the plunger, and a second portion of the second linkage is pivotable about a third portion of the first linkage.

    Abstract: A hub assembly for use with an endoscopic assembly of a reposable surgical clip applier includes an outer housing defining a channel therethrough, a driver gear slidably disposed within the channel, a transmission gear slidably and rotatably supported within the channel, and a display gear slidably and rotatably supported within the channel. Each of the driver gear, transmission gear, and display gear is configured for reciprocal movement within the channel. Distal advancement of the driver gear causes a corresponding distal advancement of the transmission gear and distal advancement of the transmission gear causes a corresponding distal advancement of the display gear. The transmission gear is caused to the rotated in a first direction during each distal advancement of the driver gear and the display gear is caused to be rotated in the first direction during a predetermined distal advancement of the transmission gear.

    Abstract: An auxiliary return system for use with a bipolar electrosurgical device includes a tissue guard defining an open proximal end, an open distal end, and a lumen extending therethrough between the open proximal end and the open distal end. A ground plate is disposed along an inner peripheral surface of the lumen and is operably coupled to a first end of a ground wire extending from the tissue guard. A coupling is included having a bore defined therein for receiving a cable from an electrosurgical device therethrough, the cable including active and ground leads. The coupling has a flange extending therefrom defining a receptacle therein configured to operably receive a plug connected to a second end of the ground wire. The receptacle is configured to provide electrical continuity between the ground lead disposed within the cable and the plug coupled to the ground wire which, in turn, provides electrical continuity to the ground plate.

    Abstract: A smoke evacuator for use with a surgical access device includes an evacuation ring having an inner peripheral surface defining one or more channels therein disposed in fluid communication with an operating cavity. A connection port is disposed thereon in fluid communication with the channel(s) and adapted to connect to a smoke evacuation system. The evacuation ring includes a profile having an inner flange that forms part of the inner peripheral surface of the evacuation ring and one or more lower flanges, the inner flange is configured to mechanically engage a rim of an access device and the lower flange(s) is adapted to mechanically engage a wound guard, wherein engagement of the inner flange of the evacuation ring atop the access device and engagement of the lower flange(s) with the wound guard secures the access device, the wound guard and the smoke evacuation ring within the operating cavity.
