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.

Methods of forming an anastomosis between organs with an expandable pattern

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.

Circular surgical stapler having staples with expandable crowns

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.

Circular surgical stapler for forming cross-pattern of staples

A surgical instrument includes a body, a shaft assembly, an end effector, and an electrical contact assembly. The body includes a power source. The shaft assembly extends distally from the body, the end effector is distal of the shaft assembly. The end effector includes a channel assembly and a cartridge assembly. The cartridge assembly may selectively couple with the channel assembly. The cartridge assembly includes an electrically activated component. The electrical contact assembly is configured to electrically couple the power source with the electrically activated component. The electrical contact assembly includes a first electrical contact associated with the channel assembly, a second electrical contact associated with the channel assembly, and a hydrophobic layer extending between the first electrical contact and the second electrical contact.

Staple cartridge with short circuit prevention features

A surgical instrument includes a body, a shaft assembly, an end effector, and an electrical contact assembly. The includes a power source, while the shaft assembly extends distally from the body. The end effector includes a channel assembly and a cartridge assembly configured to selectively couple with the channel assembly. The cartridge assembly includes an electrically activated component. The electrical contact assembly is capable of electrically coupling the power source with the electrically activated component of the cartridge assembly. The electrical contact assembly includes a first electrical contact, a second electrical contact, and an insulating membrane. The first electrical contact is associated with the channel assembly while the second electrical contact is associated with the cartridge assembly. The insulating membrane is associated with either the first electrical contact or the second electrical contact. The insulating membrane is configured to transition between a closed position and an opened position. Either the first electrical contact or the second electrical contact is configured to transition the insulation membrane to the opened position when the cartridge assembly is coupled to the channel assembly.
