    摘要： A surgical device is disclosed which includes a handle portion, a central body portion and a Simple Use Loading Unit (“SULU”) [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 clip with advantageous closure characteristics is disclosed which includes a bail portion having first and second back portions joined at an apex, and rectilinear leg portions extending from the back portions. The apex is preferably characterized by an angle of no more than about 100.degree.. Preferably the outer surface of at least one back portion includes a compression ridge to concentrate the compression force applied by the jaws of the applying instrument to a preselected region of the clip. The legs retain their parallelism while the clip is being closed. Additional features include interlocking ridges and/or projections on one of the legs which engage corresponding recesses on the other leg to enhance clip retention on tissue and to help minimize twisting and/or scissoring of the clip legs during closure.

    摘要： Disclosed is a surgical stapling apparatus and method of use that includes a cartridge assembly which is capable of being reloaded during a surgical procedure without being removed from the surgical site. This allows a surgeon to continue a surgical operation without withdrawing or removing the surgical stapler for reloading and thus reduces the length of the surgery while allowing the physician to concentrate solely on the surgical procedure rather than dividing attention between the surgical procedure and reloading of the surgical stapler. The surgical stapling apparatus includes an elongate member having a plurality of fasteners arranged in a plurality of longitudinally extending rows which is longitudinally translatable through the cartridge to position the plurality of fasteners relative to a plurality of retention slots extending through an upper surface of the cartridge.

    摘要： A surgical device is disclosed which includes a handle assembly, an elongated member and a disposable loading unit. The handle assembly includes a mode selection mechanism configured to alternate the surgical device between a first grasping mode of operation and a second clamping mode of operation. The handle assembly includes a rotation control member and an articulation lever. The rotation control member is configured to facilitate rotation of the elongated member with respect to the handle assembly. The articulation lever is configured to facilitate articulation of the tool assembly about an axis substantially perpendicular to the longitudinal axis of elongated member. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly configured to clamp and staple tissue in the second clamping mode of operation of the device.
