20180008264 · 2018-01-11 · ·

Disclosed is an end effector of a surgical linear stapler, which includes a staple cartridge, an anvil, a pusher unit, a driving wedge, a stabilizer unit and a blade unit, wherein the stabilizer unit is arranged on the staple cartridge while neighboring on the pusher unit and at least partially discharged from the staple cartridge by the driving wedge so as to hold tissue placed in between the staple cartridge and the anvil.

TREATMENT DEVICE
20180008265 · 2018-01-11 · ·

A treatment device includes: an operating section; an elongated insertion section connected to the operating section; a pair of clamp members provided at the distal end of the insertion section so as to be openable and closable relative to each other; a movable member that is moved so as to push staples relative to tissue sandwiched between the clamp members; and a coil member that is arranged so as to pass through the insertion section in the longitudinal direction and that transmits a pressing force from the operating section to the movable member.

Surgical stapler tool assembly to minimize bleeding

A cartridge assembly for a surgical stapling device includes a staple cartridge that includes a staple array that has a configuration to minimize blood leakage through a staple line formed by the staple cartridge.

Knitted tissue scaffolds

Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.

11707277 · 2023-07-25 · ·

A surgical stapling apparatus includes a shaft assembly, an end effector secured to the shaft assembly, a firing assembly, and an articulation assembly. The firing assembly includes a drive beam and a flexible knife bar assembly that are selectively advanceable through the end effector for firing the end effector. The articulation assembly has an articulation link assembly and a pivotable bar guide assembly. The articulation link assembly is coupled to the end effector and actuatable to cause the end effector to articulate relative to the shaft assembly. The pivotable bar guide assembly supports the flexible knife bar assembly and includes a proximal guide assembly and a distal guide assembly that are pivotably coupled together. The proximal guide assembly is pivotably coupled to the shaft assembly. The distal guide assembly is pivotably coupled to the end effector.

END EFFECTORS, SURGICAL STAPLING DEVICES, AND METHODS OF USING SAME

An end effector for stapling and cutting an anatomical structure includes an anvil, a cartridge, and a blade. The anvil has an anvil face and a plurality of staple pockets positioned on the anvil face. The cartridge has a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples. Each of the plurality of staples comprises a first staple leg, a second staple leg, and a crown connecting the first and second staple legs and having a midpoint. Each of the plurality of staples comprises an open staple configuration and a closed staple configuration where a first portion of the first staple leg and a second portion of the second staple leg are bent relative to the crown such that the first portion of the first staple leg and the second portion of the second staple leg cross the midpoint of the crown.

PACKAGING FOR SURGICAL STAPLER BUTTRESS

A packaging assembly is designed for an applicator that contains a buttress assembly that is used with a surgical stapler to reinforce a cut and stapled tissue site. The packaging assembly protects the buttress assembly from damage due to physical contact as well as exposure to adverse environmental factors like excess moisture, etc. In one example the packaging assembly includes a dual tray design with an inner tray that holds the applicator. The combined inner tray and applicator are hermetically sealed within a foil assembly or foil pouch. The foil pouch with the inner tray and applicator within is placed within the outer tray to protect the foil from damage.

Tool assembly for a surgical stapling device

A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.

Fastener cartridges including extensions having different configurations

A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

Surgical shaft assemblies with flexible interfaces

A slip ring assembly is used with a surgical shaft assembly. The slip ring assembly includes a slip ring, a first conductor mounted on the slip ring, a commutator rotatable relative to the slip ring, and a second conductor mounted on the commutator. The slip ring assembly further includes a flexible member disposed between the slip ring and the commutator. The flexible member comprises a body and flexible protrusions extending from the body, wherein the flexible protrusions are elastically deformed against the first slip ring.
