A surgical kit includes a stapling device and a powered actuation assist detachably couplable to the stapling device. The stapling device includes an anvil half section, a cartridge receiving half section, and a firing assembly including an actuation knob movable along a length of the cartridge receiving half section. The powered actuation assist includes a motor assembly, a lead screw operatively coupled to the motor assembly, a knob connector coupled to the lead screw, a battery pack, and a first switch electrically coupled to the motor to activate the motor. The knob connector is configured to detachably engage the actuation knob of the stapling device to impart axial displacement to the actuation knob. Actuation of the motor assembly imparts rotation to the lead screw, which, in turn, causes axial displacement of the actuation knob of the firing assembly.

A shipping cover for a staple cartridge includes a body having an upper surface and a lower surface that is in close opposition to the staple cartridge when the shipping cover is secured to the staple cartridge. The shipping cover includes a latch that is received within a body of the staple cartridge to secure the shipping cover to the cartridge body. The latch is manually movable by a clinician to facilitate removal of the shipping cover from the staple cartridge.

Shipping cover for staple cartridge

A shipping wedge () for a staple cartridge includes a body (), an elongate fin (), at least one tooth (), and a knife stop (). The elongate fin () is supported on a bottom surface () of the body (). The tooth () extends from the bottom surface () on the proximal portion of the body () and is positioned to be received within a recess formed in the staple cartridge (). The knife stop () extends from a top surface () of the proximal end of the body and is positioned to obstruct movement of a knife bar () of the staple cartridge () when the shipping wedge () is attached to the staple cartridge (). A sled stop member () extends from the bottom surface () on the proximal portion of the body () of the shipping wedge () and is positioned to obstruct movement of an actuation sled of the staple cartridge ().

A surgical stapling instrument includes an anvil body defining a longitudinal axis, a cartridge body coupled to the anvil body, a staple cartridge releasably mounted relative to the cartridge body, a firing member mounted to the cartridge body and configured for longitudinal movement through the staple cartridge, and a lockout member supported by the cartridge body. The lockout member defines a single longitudinal slot for at least partial reception of the firing member. The lockout member is configured for movement from a locked position preventing longitudinal movement of the firing member to a release position permitting longitudinal movement of the firing member upon mounting of the staple cartridge to the cartridge body.

A surgical stapling apparatus includes a handle, an elongated body, a firing assembly, and a stapling assembly. The body extends from the handle and includes an engagement member rotatably supported on to a distal portion of the body. The engagement member defines an engagement slot and is axially movable about the body from a retracted position to an advanced position. The firing assembly includes a trigger, firing link, and pusher link. The pusher link is movably supported for distal translation through the body in response to actuation of the trigger. The stapling assembly houses a plurality of surgical staples and includes an outer shell having an engagement tab. The engagement member is rotatable relative to the body and the stapling assembly to releasably position the engagement tab within the engagement slot, thereby securing the stapling assembly at the distal end of the body.

A surgical stapling device includes a handle assembly, a central body extending distally from the handle assembly, and a head portion including an anvil assembly and a shell assembly. The shell assembly includes an annular knife having an inner surface and an outer surface and first and second angled surfaces defining a blade edge. The first angled surface defines an angle Swith a longitudinal axis of the stapling device and the second angled surface defines an angle Swith the longitudinal axis of the stapling device.

A surgical stapling device () having an indicator mechanism that is movable between first, second and third positions. The first position of the indicator () indicates to a clinician that the jaws of the surgical stapling device () have yet to be approximated. The second position of the indicator () indicates to a clinician that the jaws of the surgical stapling device () are approximated. The third position of the indicator () indicates to a clinician that the surgical stapling device () has been fired and is depleted of staples.

A surgical stapling apparatus () having an adjustable minimum tissue gap (G) is provided. The surgical stapling apparatus () includes a proximal handle portion (), an elongated central body portion (), a distal head portion (), an anvil assembly (), and an approximation assembly (). The approximation assembly () includes a drive screw (), a screw stop (), and a screw extension (). The adjustable minimum tissue gap (G) can be adjusted by selectively securing the screw extension () to the drive screw () using a first or second pair of openings () of the drive screw (). A method is also provided to determine the minimum tissue gap (G) of the surgical stapling apparatus ().

Surgical stapling apparatus

A loading unit () including a shipping member () is provided. The shipping member () is receivable on a distal end of the loading unit () in a first orientation to prevent movement of a pusher assembly () from a first to a second position and in a second orientation to effect separation of the loading unit () from a surgical stapling device ().
