A surgical stapling device includes an anvil assembly and a replaceable cartridge assembly. The cartridge assembly includes a knife blade and upper and lower alignment pins for retaining tissue between anvil and cartridge assemblies to ensure that the knife blade cuts cleanly through tissue. The cartridge assembly includes a cartridge body having guide structure for guiding the cartridge assembly onto a clamp slide assembly of the stapling device.

A surgical stapler, a cartridge for a surgical stapler, a cutting mechanism for a surgical stapler, and a method of applying surgical staples in a patient are disclosed herein. The stapler may have an anvil movably coupled to a support jaw between a clamped configuration and a closed configuration. The cartridge may be configured to fit within an envelope diameter and to removably house a plurality of B-form staples, at least one of the plurality of B-form staples having a base length and a leg length, the leg length at least 53% of the envelope diameter. The cartridge may have slots shaped to house at least a second one of the plurality of staples at an angle oblique to the first one of the plurality of staples.

In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.

A bendable endoscopic linear cutting anastomat and assembly includes an anastomat jaw, a turning connection block, an assembly inner core and a cutting blade assembly. The assembly inner core includes an inner core shell and an inner core connection block fixedly mounted in the inner core shell. The front end of the turning connection block is hinged to the rear end of the anastomat jaw, a first vertical rotation shaft is formed at the hinge, the rear end of the turning connection block is hinged to the front end of the inner core connection block, a second vertical rotation shaft is formed at the hinge; the cutting blade assembly penetrates through the inner core connection block, the turning connection block and the anastomat jaw, and can slide forwards and backwards. As a result, a U-shaped left and right bending sheet which controls the bending process.

A surgical stapling device (10) includes an anvil (22) and a reload assembly (50) that includes a cartridge assembly (20) and a cutting plate (54). The reload assembly (50) is removably coupled to the stapling device (10) to facilitate replacement of the cartridge assembly (20) and the cutting plate (54) on the stapling device (10). In certain aspects of the disclosure, the reload assembly (50) also includes a shipping cap (52) that is supported on the cartridge assembly (20) and supports the cutting plate (54).

An end effector for use to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, has a formed configuration in which a first portion of a first staple leg and a second portion of a second staple leg are bent relative to a crown and cross the midpoint of the crown and one of the first portion and the second portion overlaps the other of the first portion and the second portion.

A surgical system is disclosed including an end effector, a control circuit, a closure member, and a firing member. The end effector includes a first jaw, a second jaw, and an electrode. The first jaw is rotatable relative to the second jaw between an open position and a close position to capture tissue therebetween. The electrode is configured to conduct a sub-therapeutic RF current to the tissue. The control circuit is operably coupled to the electrode. The control circuit is configured to measure impedance of the tissue over time based on the sub-therapeutic RF current. The closure member is configured to move the first jaw towards the second jaw at a closure rate based on the impedance of the tissue. The firing member is configured to move within the end effectors towards a fired position at a firing rate based on the impedance of the tissue.

A surgical stapling device includes an end effector for a transverse type surgical stapling device that includes a U-shaped frame, an anvil assembly, and a cartridge assembly. The anvil assembly is supported on the U-shaped frame and includes a cutting plate that has a thickness that changes between its first and second ends to compensate for deformation of the frame during firing of the stapling device.

A surgical stapling device includes a cartridge assembly including a staple pusher, a knife holder, a knife supported on the knife holder, and a biasing member. The biasing member is positioned between the staple pusher and the knife holder to prevent re-advancement of the knife blade after the stapling device is fired.

A surgical stapling device includes a removable or releasable cartridge assembly. The surgical stapling device and the cartridge assembly include engagement members for releasably securing a thrust bar of the stapling device to a knife assembly of the cartridge assembly. The stapling device also includes structure to prevent the knife assembly from being disengaged from a cartridge body of the cartridge assembly and for obstructing advancement of the knife assembly within the cartridge body after the stapling device has been fired.
