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.

A surgical stapling apparatus includes a staple cartridge and an anvil member. The staple cartridge includes a plurality of surgical fasteners disposed in rows of retention slots. The staple cartridge may have an annular or linear configuration of retention slots. The tissue contacting surface of the staple cartridge may be tapered or stepped. The anvil member has a tissue contacting surface that includes a number of pockets arranged for substantially aligning with the retention slots. In addition, the tissue contacting surface of the anvil member may complement the tissue contacting surface of the staple cartridge.

A surgical instrument including a handle portion, a body portion, an articulating tool assembly and a locking assembly is disclosed. The handle portion includes a movable handle. The body portion extends distally from the handle portion and defines a first longitudinal axis. The articulating tool assembly defines a second longitudinal axis and is movable from a first position where the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position where the second longitudinal axis is at an angle to the first longitudinal axis. The locking assembly includes a member that is advanceable distally with respect to the body portion. The member engages the articulating tool assembly upon manipulation of the movable handle to move an anvil and a cartridge assembly in approximation with one another to help maintain the articulating tool assembly in its first position.

A staple cartridge assembly comprising a cartridge housing, a plurality of staples, a plurality of staple pushers, and an actuation sled is disclosed. Each staple pusher includes a first base portion, and a second base portion laterally and longitudinally spaced from one another. The actuation sled disposed in the cartridge housing and is longitudinally translatable therethrough to move the staple pushers. The actuation sled includes at least a first cam wedge and a second cam wedge arranged to engage the first base portion and the second base portion of the pushers. The first cam wedge is laterally and longitudinally spaced apart from the second cam wedge.

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.

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.

The present disclosure describes a surgical fastener applying apparatus that includes an elongate body portion having proximal and distal ends, an end effector including a first movably coupled to a second jaw that is positioned at the distal end of the elongate body portion, and an introducer member. The introducer member has proximal and distal portions, and is configured and dimensioned for releasable connection with the end effector. The introducer member is at least partially formed from a flexible material, and is configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector.
