    摘要: A surgical instrument includes an end effector and a staple cartridge that is insertable into the end effector. The staple cartridge includes a buttress material that is selectively coupled to the staple cartridge. In some versions the buttress material may be stapled to the staple cartridge by one or more attachment staples. Such attachment staples may be inserted into staple apertures formed through an upper deck of the staple cartridge. The attachment staples may include resiliently biased legs to frictionally resist removal. In some versions the attachment staples may be sized to form an interference fit in the staple apertures. Alternatively, the attachment staples may include barbs. A staple driver may be used to decouple the attachment staples. The staple driver may include staple forming pockets to bend the legs of the attachment staple when decoupling the attachment staple.

    摘要: Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise a hollow flexible sheath that has a distal end and an open proximal end that is sized to receive a stapling head portion of the circular stapler therein. A radially-openable barrel member is attached to a distal end of the hollow flexible sheath to define an opening for receiving the stapling head therein. A rigid cap member is hingably attached to the radially-openable barrel member and is movable between a closed position wherein the rigid cap member covers a distal end of the opening in the barrel member and open position wherein the rigid cap member is movable to a position wherein the distal end of the opening is exposed. A releasable latch member is provided to engage and release opposed ends of the radially-openable barrel member.
