A cartridge assembly includes a channel and a removable assembly in releasable engagement with the channel. The removable assembly includes a cartridge body and a support plate. The cartridge body includes an engagement structure disposed adjacent a proximal end thereof. The support plate is configured to mechanically engage the cartridge body and includes an engagement structure disposed adjacent a proximal end thereof. The engagement structure of the cartridge body is configured for longitudinal alignment with the engagement structure of the support plate. The engagement structures of the cartridge body and the engagement structure of the support plate are configured to mechanically engage the engagement structure of the channel when the removable assembly is engaged with the channel.

Multi-use loading unit

A surgical apparatus having an electrical conductor with a strain relief is provided. A tool assembly is supported on a body portion and is articulable relative to the body portion. The tool assembly includes an identification assembly in electrical communication with a powered handle assembly. An electrical conductor extends from a connection assembly in the body portion to the identification assembly. The electrical conductor includes a strain relief portion for accommodating the articulation of the tool assembly relative to the body portion.

Surgical apparatus with conductor strain relief

An end effector of a surgical stapler includes first and second jaw members and a buttress releasably secured to the first jaw member. The first jaw member defines a first projection and a second projection distal of the first projection. The buttress defines a first slot and a first aperture distal of the first slot. The first slot is dimensioned to receive the first projection of the first jaw member, and the first aperture is dimensioned to receive the second projection of the first jaw member.

Structure for attaching buttress to anvil and/or cartridge of surgical stapling instrument

A surgical stapling apparatus includes a cartridge assembly defining a tissue contacting surface; an anvil assembly defining a tissue contacting surface; and a surgical buttress releasably secured to at least one of the tissue contacting surface of the cartridge assembly and the tissue contacting surface of the anvil assembly by at least one anchor. A loading unit includes a surgical buttress releasably secured to an anvil assembly and/or a staple cartridge secured thereto by at least one anchor, and a drive assembly including a knife blade, wherein movement of the drive assembly from a proximal position to a distal position results in the knife blade cutting the at least one anchor and freeing each surgical buttress from the anvil assembly and/or cartridge assembly.

Surgical stapling apparatus

A surgical stapler has a tool assembly including an anvil and a staple cartridge having a series of staples which are supported and configured to be rotatably ejected from the staple cartridge into the anvil to suture tissue. In embodiments, the surgical stapler includes a cartridge that supports a plurality of rotatable pushers. Each pusher supports a curved, substantially U-shaped staple having a single tissue penetrating distal leg portion and a proximal leg portion. The pusher is rotatable to drive the distal leg portion into an anvil to deform the staple into a substantially D-shaped configuration.

Endoscopic stapler and staple

A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.

Surgical stapler with small diameter endoscopic portion

A surgical stapling apparatus includes an actuating device including an elongated shaft. A tool assembly is disposed on a distal end of the shaft. The tool assembly includes a first jaw member supporting a cartridge assembly having a plurality of surgical fasteners, and a second jaw member supporting an anvil. The first jaw member is movable in relation to the second jaw member between a spaced position and an approximated position. One of the first or second jaw members includes a cantilever at a proximal end thereof. A firing cam bar assembly is slidably disposed within the tool assembly and includes a cam surface configured to engage the cantilever to move the first and second jaw member towards the approximated position and a distal end configured to deploy the plurality of surgical fasteners from the cartridge assembly.

Surgical apparatus

An end effector of a surgical stapler includes first and second jaw members and a buttress material. The first jaw member is moveable relative to the second jaw member. The first jaw member includes a contact surface, a first projection, and a catch. The catch includes first and second fingers distal of the first projection. The second finger is biased toward the contact surface. The buttress material defines a longitudinal axis. The buttress material is releasably secured to the first jaw member. The buttress material defines first, second, and third slots formed therein. The first projection of the first jaw member is received in the first slot of the buttress material. The first finger of the catch is received in the second slot of the buttress material.

Structure for attaching buttress material to anvil and cartridge of surgical stapling instrument

A cartridge assembly is disclosed. The cartridge assembly includes a channel and a removable assembly in releasable engagement with the channel. The removable assembly includes a cartridge body and a support plate. The cartridge body includes an engagement structure disposed adjacent a proximal end thereof. The support plate is configured to mechanically engage the cartridge body and includes an engagement structure disposed adjacent a proximal end thereof. The engagement structure of the cartridge body is configured for longitudinal alignment with the engagement structure of the support plate. The engagement structures of the cartridge body and the engagement structure of the support plate are configured to mechanically engage the engagement structure of the channel when the removable assembly is engaged with the channel.

A surgical apparatus including an electrical conductor with a strain relief is provided. A tool assembly is supported on a body portion and is articulable relative to the body portion. The tool assembly includes an identification assembly in electrical communication with a powered handle assembly. An electrical conductor extends from a connection assembly in the body portion to the identification assembly. The electrical conductor includes a strain relief portion for accommodating the articulation of the tool assembly relative to the body portion.
