摘要： In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

摘要： A surgical stapling instrument including an actuator configured to be retracted relative to the distal end of the disposable loading unit and rotate an anvil between an open position and a closed position. The actuator can include a cam, where the cam can include an arcuate profile having an apex configured to be in contact with the anvil when the anvil is in a closed position. In at least one such embodiment, the anvil can apply a clamping force to the soft tissue prior to the staples being deployed to prevent, or at least inhibit, soft tissue from flowing, or ‘milking’, out of the distal end of the disposable loading unit. In various embodiments, a surgical stapling instrument can include a disposable loading unit having an anvil which can be moved between open, closed, and/or collapsed positions to facilitate the insertion of the disposable loading unit through a trocar.

摘要： A tissue thickness compensator may generally comprise a first layer comprising a first biocompatible material sealingly enclosed in a water impermeable material and a second layer comprising a second biocompatible material comprising at least one encapsulation, wherein the first biocompatible material expands when contacted with a fluid. The tissue thickness compensator may comprise a haemostatic agent, an anti-inflammatory agent, an antibiotic agent, anti-microbial agent, an anti-adhesion agent, an anti-coagulant agent, a medicament, and/or pharmaceutically active agent. The encapsulation may comprise a biodegradable material to degrade in vivo and/or in situ. The tissue thickness compensator may comprise a hydrogel. The reaction product may comprise a fluid-swellable composition. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.
