    摘要： A surgical instrument comprising a handle assembly, and actuation member, an elongated body portion, and a locking mechanism is disclosed. The locking mechanism is disposed in mechanical cooperation with the actuation member, and is configured to substantially prevent at least a partial movement of the actuation member when the elongated body portion is not engaged with a loading unit. The locking mechanism comprises a link, a bushing, and a connecting member. The link is configured for mechanical engagement with a portion of a loading unit. At least a portion of the busing is disposed proximally of at least a portion of the link. At least a portion of the connecting member is disposed proximally of at least a portion of the bushing. Engagement between a loading unit and the elongated body portion causes proximal movement of the link, the bushing, and the connecting member.

    摘要： A buttressed anvil assembly is provided for use with a surgical stapling instrument. The buttressed anvil assembly generally includes an anvil member having a strip of buttress material attached thereto by a pair of sutures. A tensioning mechanism is provided to secure or tension the buttress material to the anvil member prior to use and allow for release of the buttress material after stapling of tissue. The tensioning mechanism includes a cinch track engageable with one of the pair of sutures.

    摘要： A tool assembly for a surgical stapling device includes a channel member for supporting a staple cartridge therein and an anvil to deform a plurality of staples ejected from the staple cartridge thereagainst. The tool assembly also includes a sled which is movable to force the staples from the cartridge against the anvil to staple tissue disposed between the anvil and the staple cartridge. A dynamic clamping member is included which has a pin which movably engages the anvil and a flange which movably engages the channel assembly. The dynamic clamping member is mounted to and movable with the sled. The pin and the flange of the dynamic clamping member cooperating to oppose the forces associated with clamping and stapling tissue and also to maintain a substantially uniform gap between the anvil and the staple cartridge during stapling of the tissue.

    摘要： A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.

    摘要： A surgical stapling apparatus (stapler) is provided. The stapler includes a housing, elongated member, and a reload. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.
