A circular stapler including a cartridge assembly and an anvil assembly is provided. The cartridge assembly includes a rotatable drive shaft and the anvil assembly includes first and second pull cables. When the anvil assembly engages the cartridge assembly, retraction of the first pull cable effects clamping of tissue between the anvil assembly and the cartridge assembly, and retraction of the second pull cable effects stapling and cutting of the clamped tissue.

A surgical instrument is disclosed. The surgical instrument includes a handle assembly, a drive assembly, an endoscopic portion, a pair of jaw members, a dynamic clamping member, and a tissue stop. The drive assembly is disposed in mechanical cooperation with a movable handle of the handle assembly. The endoscopic portion defines a first longitudinal axis. The jaw members are each longitudinally curved with respect to the longitudinal axis. The dynamic clamping member is disposed in mechanical cooperation with a distal portion of the drive assembly and includes an upper beam, a lower beam, and a vertical beam having a cutting edge on a distal portion thereof. At least a portion of the dynamic clamping member is longitudinally curved with respect to the longitudinal axis. The tissue stop is disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members.

A device that may be used as a surgical stapler comprises five rows of staples towards the segment one wishes to suture and one row towards the segment that is extracted. In a back area it comprises two sections separated in the middle for a knife to pass through. At least one of the sections presents a curve-shaped end to adapt it to the stapler.

An assembly for fastening tissue is disclosed. The assembly may comprise a first jaw comprising a cartridge, wherein the cartridge comprises a plurality of fasteners. The plurality of fasteners comprises a first fastener comprising a first height and a second fastener comprising a second height, wherein the second height is different than the first height. The assembly further comprises a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other. The second jaw comprises a plurality of fastener-engaging portions. The plurality of fastener-engaging portions comprises a first fastener-engaging portion and a second fastener-engaging portion. The assembly further comprises a compressible layer intermediate the first jaw and the second jaw.

A surgical instrument comprising a shaft, an end effector rotatable relative to said shaft about an articulation joint, an articulation system configured to rotate the end effector, and an articulation lock. The articulation lock is configured to selectively couple the articulation system to a frame of the shaft. In various embodiments, the surgical instrument further comprises a lock plate movable within the shaft frame. In such embodiments, the articulation lock is configured to lock the articulation system to the lock plate.

A method is used to manufacture a frame of a curved surgical stapler. The method includes manufacturing a first portion of the frame of the curved surgical stapler separate from the first portion. The first portion includes a first curvilinear portion of an end effector and a first alignment feature. The method also includes manufacturing a second portion of the frame of the curved surgical stapler. The second portion includes a second alignment feature. The method also includes manufacturing a third portion of the frame of the curved surgical stapler separate from either of the first or second portions. The third portion includes a C-shaped track. The method also includes aligning the first and second portions portion with the second portion by aligning the first and second alignment features. The method also includes coupling the first and second portions of the frame of the curved surgical stapler together.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

The present disclosure provides for a surgical instrument which includes a housing and an endoscopic portion extending distally from the housing and defining a first longitudinal axis. The surgical instrument also includes an end effector disposed adjacent a distal portion of the endoscopic portion. The end effector includes an anvil assembly and a cartridge assembly. The anvil assembly is pivotally coupled to the cartridge assembly to be movable from a first actuation position to at least one other second actuation position. The surgical instrument further includes a firing rod having a shaft defining a second longitudinal axis, the shaft having a cam member which is in mechanical cooperation with the anvil assembly and is configured to move the anvil assembly from the first actuation position to the at least one other second actuation position upon rotation of the firing rod about the second longitudinal axis.

A surgical instrument including a channel that is configured to support a replaceable surgical staple cartridge therein. An anvil is movably supported on the channel and is configured to selectively move between an open position and a closed position. A rotary driven closure system operably interfaces with the anvil and is configured to move the anvil between the open position and the closed position upon application of rotary opening and closing motions thereto. The instrument also includes a rotary driven firing drive shaft and an axially movable firing member that is in driving engagement with the rotary driven firing drive shaft and is configured for sliding engagement with the channel and the anvil upon application of rotary firing motions to the rotary driven firing drive shaft.

An end effector for a medical device includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket and a second staple pocket, each defined by the anvil face. The first staple pocket includes a first surface having a first depth, and the second staple pocket includes a second surface having a second depth. The cartridge has a first staple having a first height in an open configuration, a first driver, a second staple having a second height in an open configuration, and a second driver. A first staple formation distance is defined by a first distance between the first driver and the first surface of the first staple pocket when the anvil and the cartridge are in a closed position. The first staple formation distance differs from a second staple formation distance.
