In various forms, the buttress material comprises a buttress body that is sized to be operably received on a deck of the surgical staple cartridge. The buttress body includes at least four edges and a central portion. At least two of the edges have a plurality of edge notches formed therein. The central portion may include a plurality of cutout openings therein.

Adjunct material with mating features

An adjunct material for use with an end effector for a surgical instrument is provided that has different types of features for mating with the end effector. The adjunct is configured to be releasably retained on a jaw, such as a cartridge or anvil, using a plurality of female features formed thereon. Each female feature is configured to encompass a corresponding at least one of male features formed on the jaw in a clearance fit such that the adjunct is able to move with respect to the jaw at least in a first plane parallel to the tissue-facing surface. The male and female features mate such that the adjunct is not retained in a second plane that is perpendicular to the first plane. The adjunct also includes at least one attachment feature configured to releasably retain the adjunct on the jaw.

Buttress systems and methods for surgical stapling devices and end effectors

Embodiments include a surgical instrument having an end effector, the end effector including a first jaw having a first end, a second end, and an anvil, the anvil having an anvil face, a second jaw having a first end, a second end, and a cartridge to house a plurality of staples, the cartridge having a cartridge face, a first coupling that couples the first end of the first jaw to the first end of the second jaw, and a second coupling that movably couples the second end of the first jaw to the second end of the second jaw, where the second coupling includes a rigid link, an elongate tube, where a distal end is coupled with the end effector, a handle, where a distal end of the handle is coupled with a proximal end of the elongate tube, and a drive assembly comprising a motor.

Surgical stapling devices have a metal coating on an anvil jaw member of the surgical stapling device, on a surface of staple pockets of a staple cartridge of the surgical stapling device, or any combination thereof. When the surgical stapling device is fired, the metal is transferred from the metal coating on the anvil jaw member, the staple pockets of the staple cartridge, etc., onto the staple. The resulting metal coating on the staple enhances healing of the tissue to which the staple is applied.

ARTICULATION DRIVE FEATURES FOR SURGICAL STAPLER

An apparatus comprises a shaft, an end effector, an articulation joint, and an articulation drive assembly. The shaft has a longitudinal axis. The end effector is operable to staple tissue. The articulation joint couples the shaft with the end effector. The end effector is pivotable at the articulation joint to selectively deflect the end effector away from the longitudinal axis of the shaft. The articulation drive assembly is operable to pivot the end effector at the articulation joint. The articulation drive assembly comprises a first link and a second link. The first link is longitudinally translatable relative to the shaft assembly. The distal end of the first link is pivotably coupled with the proximal end of the second link. The distal end of the second link is pivotably coupled with the end effector. The articulation drive assembly articulates the end effector in response to longitudinal translation of the first link.

STAPLE CARTRIDGE COMPRISING A STAPLE DRIVER ARRANGEMENT

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

METHOD OF APPLYING A BUTTRESS TO A SURGICAL STAPLER END EFFECTOR

A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.

METHOD OF APPLYING A BUTTRESS TO A SURGICAL STAPLER

A method of applying a buttress to a surgical stapler end effector comprises positioning a buttress assembly between an anvil and a staple cartridge of the end effector. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material faces either an underside of the anvil or a deck of the staple cartridge. The anvil is in an open position relative to the staple cartridge during the act of positioning the buttress assembly between the anvil and the staple cartridge. The method further comprises moving the anvil toward the staple cartridge then moving the anvil back to the open position. The buttress assembly is adhered to the underside of the anvil or the deck of the staple cartridge via the adhesive material with the anvil moved back to the open position. The adhesive material comprises a bioabsorbable polymer.

SURGICAL INSTRUMENT COMPRISING AN ADAPTIVE CONTROL SYSTEM

A surgical instrument system comprising an adaptive control system is disclosed.
