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 single use loading unit, or “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 staple drive assembly includes an actuation sled and at least one staple pusher. The staple drive assembly is adapted to fit within a staple cartridge having a plurality of staples and a corresponding number of retention slots. The at least one staple pusher includes at least one pusher plate for releasably engaging a backspan of a staple. The staple pusher may include a plurality of pusher plates that may be laterally and longitudinally spaced apart. An actuation member has at least one angled camming surface for engaging a complimentary angled surface of the at least one staple pusher. Camming engagement between the actuation member and the at least one staple pusher causes vertical movement of the at least one staple pusher. Lateral and longitudinal offset of the actuation member camming surfaces and the corresponding staple pusher following surfaces improves stability and control of the staple pusher during firing.

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 signal detection arrangement is disclosed for detecting signals during variable speed tape movements such as during tape rewinding or fast forward speeds. To elaborate, information encoded as multifrequency information tones is grouped in exercises on a recording tape, and at least two low frequency tones are provided at the beginning of each exercise. Each of these low frequency tones has a frequency which is related to the frequency of a different one of the information tones by a multiple of the ratio of the rewind speed to the normal forward speed times a predetermined factor. Accordingly, during normal playback these low frequency tones will not be detected. However, during fast forward or rewind, each of these tones will be multiplied up to a detectable frequency. Moreover, even over wide variations in these "fast" speeds, at least one of these low frequency tones will be detected.

摘要： A trocar for use in a minimally invasive surgical procedure includes an elongated body, nozzle means and means for delivering a pressurized flow of fluid to the nozzle means. The elongated body has a generally tubular configuration with coaxially arranged inner and outer walls and longitudinally opposed proximal and distal end portions, with the inner wall defining a lumen to accommodate passage of an instrument therethrough. The nozzle means is operatively associated with the inner wall of the body for directing pressurized fluid into the lumen to develop a pressure differential in an area within a region extending from a location adjacent a distal end portion of the lumen to a location adjacent a proximal end portion of the lumen, to form a fluid seal around an instrument passing therethrough.
