    摘要： A trocar system including a cannula and an obturator assembly being at least partially insertable through the cannula. The obturator assembly including a housing, a penetrating tip disposed at a distal end, an elongated shield including a guard extending from a shaft are movable relative to the penetrating tip, and a latch mechanism disposed generally within the housing. The latch mechanism facilitates changing the configuration of the obturator assembly between a fixed-shield orientation, wherein at least a portion of the guard is maintained to extend at least partially distal of the penetrating tip to prevent puncturing of tissue by the penetrating tip, to a non-fixed shield orientation whereby upon application of force to the distal end of the obturator assembly, the guard and penetrating tip are permitted to move relative one another to facilitate puncturing of tissue by the penetrating tip.

    摘要： A surgical access apparatus includes an access member dimensioned for insertion within tissue and having a longitudinal opening to permit introduction of a surgical object through the access member to perform a procedure on underlying tissue. A seal member is mounted across the longitudinal opening of the access member and has an internal portion defining an aperture for forming a substantial seal about the surgical object introduced through the longitudinal opening of the access member. The seal member includes a first seal portion extending from the internal portion and being mounted in suspended relation to the access member, and a second seal portion extending from the internal portion and disposed radially outward of the first seal portion, and being attached to the access member

    摘要： A seal assembly for use with an access device includes a seal housing defining a central longitudinal axis, an inner wall and an outer wall. The inner wall defines a longitudinal opening to permit passage of instrumentation through the seal housing. A gimbal mount is at least partially accommodated within a space defined between the inner wall and the outer wall of the seal housing. The gimbal mount includes a seal member defining an aperture for substantial sealed reception of a surgical instrument. The gimbal mount is adapted for angular movement relative to the central longitudinal axis upon angulation of the surgical instrument while substantially maintaining the sealed reception of the surgical instrument.

    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 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.
