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.

A surgical stapler for creating an anastomosis includes a stapling head assembly having a deck member that incorporates an alignment feature. The alignment feature aligns with a transection staple line prior to creating the anastomosis. In some versions the alignment feature is a groove formed in a surface of the deck member. The surgical stapler may include an anvil with a complementary stepped feature to the alignment feature of the deck member. Various surgical staplers with an alignment feature can be oval shaped, circular shaped, or dog-bone shaped. In some versions different staple geometries are used along the deck member incorporating the alignment feature.

A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly configured to drive a plurality of staples against the staple forming pockets of the anvil. The stapling head assembly comprises a coupling member configured to actuate the anvil relative to the stapling head assembly, a firing assembly configured to drive the plurality of staples against the staple forming pockets of the anvil, and a deck member. The deck member includes a deck surface extending radially between an inner circular edge and an outer circular edge, and a plurality of staple openings extending through the deck surface. The plurality of staple openings define at least one cross shape.

A method of creating an anastomosis is provided using a stapling assembly including a body extending distally along a longitudinal axis and a deck member defining a deck surface. The deck surface includes a first array of staple openings comprising a herringbone pattern, and each staple opening of the first array of staple openings has a same size. The method includes positioning an anvil within a first lumen of a patient and positioning the stapling assembly within a second lumen of the patient. The method also includes releasably coupling the anvil with the stapling assembly and compressing tissue of the first and second lumens between the anvil and the deck member. The method further includes actuating a plurality of staple drivers to drive a first plurality of staples distally and parallel to the longitudinal axis from the first array of staple openings into the tissue to define the anastomosis.

A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

Apparatus and methods are provided for performing a medical procedure, such as a laparoscopic appendectomy using a stapler apparatus including a reusable handle portion including a shaft include proximal and distal ends, a disposable end effector attached to the distal end of the shaft of the reusable handle carrying one or more staples. For example, the end effector may include first and second jaws movable relative to one another between open and closed positions, the first jaw carrying a cartridge which includes the one or more staples. A Doppler sensor, a cutting element, and, optionally, a thermal element are also provided on the end effector. The end effector is introduced into a patient's body, tissue is positioned/locked between the jaws, and a plurality of staples are deployed into the tissue. The Doppler sensor is used to confirm that blood flow has discontinued in the stapled tissue, and the cutting element is actuated to sever the stapled tissue.

An endoscopic surgery system includes a plurality of staples and an endoscopic applicator having a staple cartridge for loading transversely arranged staples. The staples have a central region and two side limbs and the applicator has a mobile body for holding a staple to be applied, the staple being arranged in a transverse plane, and for ensuring the deformation of same by bending in relation to the axis of symmetry of the staple.

Devices and methods are provided for stabilizing fasteners post-deployment. Devices and methods are also provided for facilitating ejection of surgical fasteners from a cartridge. Devices and methods are also provided for guiding surgical fasteners. Devices and methods are also provided for facilitating closing and clamping of an end effector of a surgical device. Devices and methods are also provided for securing fasteners and adjunct materials to tissue. Devices and methods are also provided for removably coupling a cartridge to an end effector of a surgical device. Devices and methods are also provided for locking a surgical device based on loading of a fastener cartridge in the surgical device. Devices and methods are provided for adjusting a tissue gap of an end effector of a surgical device. Devices and methods are also provided for manually retracting a drive shaft, drive beam, and associated components.
