    摘要: A method of applying a buttress to a surgical stapler end effector comprises positioning a buttress assembly between an anvil and a staple cartridge of the end effector. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material faces either an underside of the anvil or a deck of the staple cartridge. The anvil is in an open position relative to the staple cartridge during the act of positioning the buttress assembly between the anvil and the staple cartridge. The method further comprises moving the anvil toward the staple cartridge then moving the anvil back to the open position. The buttress assembly is adhered to the underside of the anvil or the deck of the staple cartridge via the adhesive material with the anvil moved back to the open position. The adhesive material comprises a bioabsorbable polymer.

    摘要: In various embodiments, a shaftless end effector is disclosed. The end effector can comprise an anvil assembly including a staple forming surface. The end effector can also comprise a staple cartridge channel configured to receive a staple cartridge therein. The end effector can include a closure system configured to close the anvil. In various instances, the closure system can also form the staples contained within the staple cartridge. The end effector can also include a cutting member configured to cut tissue positioned intermediate the anvil and the staple cartridge. In various instances, the cutting member can be actuated by the closure system. In other instances, the end effector can include an independent system for actuating the cutting member. In various instances, the end effector can be delivered to a surgical site through a trocar and then operated by one or more actuators that are assembled to the end effector.

    摘要: An apparatus comprises a body, a shaft assembly, an end effector, a cartridge, and a staple driver actuator. The end effector is operable to manipulate tissue. The end effector comprises a lower jaw, a pivotable anvil, and a translating cutter. The translating cutter is operable to translate relative to the lower jaw and the anvil when the anvil is pivoted toward the lower jaw to manipulate tissue. The cartridge is insertable into the lower jaw and includes a plurality of staples. The staple driver actuator is disposed within the cartridge. The staple driver actuator comprises a secondary cutting element. The translating cutter of the end effector is operable to drive the staple driver actuator distally to staple and cut tissue substantially simultaneously.
