A surgical instrument including a stapling assembly and an anvil configured to selectively couple with the stapling assembly to compress tissue and form staples in the tissue. The stapling assembly includes a housing extending distally along a central axis, a deck member having a plurality of staple openings configured to receive a plurality of staples, and a knife member at least partially disposed within the housing. The deck member includes an exterior perimeter having a first shape and an interior perimeter enclosed by the exterior perimeter and having a second shape different than the first shape. The knife member includes a distal end having a cutting edge that defines an edge plane that intersects the central axis. The cutting edge has a non-circular shape in the edge plane.

A surgical instrument includes a stapling assembly and an anvil that releasably couple together to compress and staple tissue. The stapling assembly includes a body having a longitudinal axis, a deck member, and a knife member surrounding the longitudinal axis. The deck member includes a deck surface having an imaginary centerline that surrounds the longitudinal axis, a first deck surface portion extending along a first angular range of the deck surface about the longitudinal axis, and a second deck surface portion extending along a second angular range of the deck surface about the longitudinal axis. A first array of staple openings is disposed on the first deck surface portion and is arranged in a first orientation relative to the deck surface centerline. A second array of staple openings is disposed on the second deck surface portion and is arranged in a second orientation relative to the deck surface centerline.

A surgical stapling instrument includes an anvil and a stapling head assembly. The anvil defines staple forming pockets. The stapling head assembly includes a body, a coupling member, a firing assembly, and a staple deck. The coupling member is configured to actuate relative to the body to thereby acuate the anvil relative to the body. The firing assembly is configured to drive staples against the staple forming pockets of the anvil. The staple deck is defined by an outer arched perimeter and an inner arched perimeter fixed to the body. The staple deck defines staple openings. At least one non-tangential staple opening in the of staple openings extends along a longitudinal axis in a non-tangential relationship with a closest tangent line of the inner arched perimeter or the outer arched perimeter.

A surgical stapler instrument includes a stapling head assembly that receives a plurality of staples. The staples are configured with features that allow the staples to expand after deployment so that an anastomosis created by the instrument can increase in size after forming. In some versions the staples expand automatically after deployment, and in other versions the staples expand in response to tissue forces imparted upon the staples after deployment. In some versions the staples are configured to be deployed in various patterns that promote expandability of the circular staple line.

The deck member includes a deck surface having an imaginary centerline that surrounds the longitudinal axis, a first deck surface portion extending along a first angular range of the deck surface about the longitudinal axis, and a second deck surface portion extending along a second angular range of the deck surface about the longitudinal axis. A first array of staple openings is disposed on the first deck surface portion and is arranged in a first orientation relative to the deck surface centerline. A second array of staple openings is disposed on the second deck surface portion and is arranged in a second orientation relative to the deck surface centerline.

A method of displaying an operational parameter of a surgical system is disclosed. The method includes receiving, by a cloud computing system of the surgical system, first usage data, from a first subset of surgical hubs of the surgical system; receiving, by the cloud computing system, second usage data, from a second subset of surgical hubs of the surgical system; analyzing, by the cloud computing system, the first and the second usage data to correlate the first and the second usage data with surgical outcome data; determining, by the cloud computing system, based on the correlation, a recommended medical resource usage configuration; and displaying, on respective displays on the first and the second subset of surgical hubs, indications of the recommended medical resource usage configuration.

A surgical kit includes a stapling device and a securing ring. The stapling device includes a reload including a trocar member and an anvil assembly including an anvil and an anvil shaft detachably couplable to the trocar member of the reload for unitary movement. The securing ring is selectively securable about the anvil shaft. The securing ring has an annular profile defining an aperture. The securing ring includes first and second portions and an intermediate portion. The first and second portions adjustably overlap each other. The first portion includes a first tab. The second portion includes a hook. The intermediate portion includes a second tab and defines slots to receive the hook of the second portion. When the first and second tabs are displaced relative to each other, the aperture is transitionable from a first state having a first diameter to a second state having a second diameter.

An anastomotic coupler is provided. A ring can include a receiving portion. A fixation device includes a cartridge. The cartridge includes a plurality of fasteners. Upon actuation of the fixation device, the fasteners puncture the tubular structure. The fasteners are received by the receiving portions such that the tubular structure is coupled with the ring.

Systems and methods for treating tissue may include one or more delivery devices, a grasping element, a first ring for anchoring to a wall of a gastrointestinal tract, and a second ring operably couplable to a radially inward surface of the first ring. Other embodiments include methods of treating tissues, including tubular tracts of tissue, comprising coupling a first ring to first tissue of a wall of a tissue tract, relocating a target tissue proximally to a position proximal to the first ring, coupling a second ring to the first ring, and cutting tissue proximal to the interface of the first and second rings.

The problem of positioning one or more nerve ends inside a sheathing implant is solved by the use of a pulley and cinching systems that pull a nerve end into an implant and that can adjust the diameter of an implant to conform the implant to the diameter of the nerve, respectively. The pulley system utilizes a suture that traverses the wall of an implant leaving one end outside the implant wall and another end that can be attached to a nerve. Pulling the suture end outside the wall pulls the nerve attached to the other end of the suture into the bore of the implant. A cinching system utilizes specially arranged sutures within the wall of an implant to tighten or cinch up the wall after a nerve is placed therein, so as to conform at least part of the implant to the diameter of the nerve. Methods are also disclosed by which such pulley systems can be formed during an intraoperative procedure.
