An end effector for use with a surgical stapler includes a staple cartridge assembly movable relative to an anvil assembly. The staple cartridge assembly defines a plurality of retention slots and a cavity. The staple cartridge assembly includes a plurality of staples, a plurality of pushers, an actuation sled, a surgical buttress material, a suture, and an anchoring button. The actuation sled is configured for movement along a length of the staple cartridge assembly to sequentially engage the plurality of pushers to eject the plurality of staples through the respective plurality of retention slots. The anchoring button is configured to be received in the cavity of the staple cartridge assembly such that a portion of the suture is supported in the cavity to be severed by a knife blade of the actuation sled when the actuation sled is advanced distally.

A method and a tool assembly maintain a tissue gap between distal portions of an anvil and a cartridge assembly of a stapling device. In embodiments, the tool assembly includes a locking member that is supported on one of the anvil and the cartridge assembly and is movable from an unlocked position to a locked position to secure distal portions of the anvil and the cartridge assembly together. In the locked position, the locking member is engaged with the distal portion of the other of the anvil and the cartridge assembly to maintain a tissue gap between the distal portion of the anvil and the cartridge assembly.

A mesh deployment device is configured to place a surgical mesh on tissue retro muscularly. In particular, the mesh deployment device includes an arm assembly that is transitionable between a retracted configuration, in which, stationary and covering arms are in superposed relation such that the surgical mesh is supported by the supporting arm therebetween, and a deployed configuration, in which, the stationary, covering, and supporting arms are circumferentially spaced apart to support the surgical mesh thereon.

A surgical stapling device is provided which includes a first jaw supporting an anvil assembly and a second jaw supporting a cartridge assembly. The cartridge assembly supports a firing lockout assembly which includes a latch member having a blocking portion. The latch member is movable between a first position and a second position. In the first position, the blocking portion of the latch member is aligned with the stop surface of the drive member to prevent advancement of the drive assembly beyond an initial advanced position within the tool assembly and in the second position, the blocking member is misaligned with the stop surface of the drive member to permit subsequent advancement of the drive assembly within the tool assembly. In the retracted position of the drive assembly subsequent to firing of the surgical stapling device, the latch member is in the first position.

Side bite surgical suturing instruments or portions thereof for endoscopic, laparoscopic, endoluminal, and/or transluminal suturing facilitate the use of larger needles to get a bigger bite while suturing.

Surgical suturing instruments

A tool assembly includes a cartridge assembly or a heating assembly along with an anvil assembly, and a drive assembly. The drive assembly includes a working member and a laser probe that is pivotally supported on the working member and emits a laser beam. The laser probe is positioned between the cartridge and anvil assemblies such that the laser beam extends across a tissue gap of the tool assembly when the tool assembly is in the clamped position.

An end effector for a surgical stapling device includes an anvil, a multiple use loading unit, and an ejector assembly. The multiple use loading unit is pivotally secured to the anvil and includes a channel member defining a cavity and a staple cartridge received within the cavity. The staple cartridge has a distal portion having an angled lower surface. The ejector assembly includes an ejector button that is supported on the channel member and engages the angled lower surface of the staple cartridge such that movement of the ejector button from an advanced position to a retracted position in relation to the channel member lifts the distal portion of the staple cartridge from the cavity of the channel member.

End effector with staple cartridge ejector

A cartridge assembly of a surgical stapling instrument includes a housing having an arcuate configuration, a knife disposed within the housing, and a staple actuator configured to eject staples. A longitudinally-extending cutting edge of the knife is configured to advance through tissue after the staple actuator ejects all of the staples from the cartridge assembly.

Surgical stapling instruments

A loading unit for use with a surgical instrument includes a body configured for coupling to a surgical instrument and defining a longitudinal axis and having proximal and distal ends, and an end effector coupled to the distal end of the body. The end effector includes a staple cartridge assembly having a staple cartridge and an anvil assembly having an anvil plate. A drive assembly is at least partially disposed within the body. The drive assembly includes an actuator member having a roller engageable with at least one of the staple cartridge assembly or the anvil assembly. The roller is configured to rotate upon longitudinal movement of the drive assembly to facilitate movement of the drive assembly and relative movement of the staple cartridge assembly and the anvil assembly between open and approximated conditions.

Loading unit for a surgical stapling instrument

A surgical stapling apparatus includes an end effector having an anvil assembly and a staple cartridge assembly, and an anvil buttress retention system releasably disposed on the anvil assembly. The anvil buttress retention system includes an anvil buttress and a retention member including an elongated body looped around at least a portion of the anvil buttress with a free end of the elongated body extendable through a looped end of the elongated body in an untightened configuration such that the anvil buttress retention system is slidable relative to the anvil assembly. The free end of the retention member is movable relative to and through the looped end to a tightened configuration to secure the anvil buttress retention system to the anvil assembly.
