摘要:
A disposable apparatus is disclosed for applying surgical clips to body tissue in endoscopic surgical procedures. The apparatus includes a frame which is adapted to be gripped by hand, and an endoscopic section permanently connected to the handle and capable of storing surgical clips in preparation for clipping arteries or other body tissue. The apparatus includes means for advancing each clip sequentially to a pair of distal jaws and means for closing the jaws about the clip. When the jaws are closed, the clip advancing means is simultaneously positioned to advance the next clip. When all clips are spent the apparatus becomes automatically locked against further advancement of the clip advancing means as well as further closing of the clip closing jaws. The present apparatus also makes it possible to partially close a clip without interfering with the sequential movement of the clip advancing mechanism.

The fascia stapler has a pistol-shaped housing from which two-piece clips can be ejected for closing an incision. The retainers for the clips and the straps for the clips are held in respective cartridges within the nose of the housing and can be ejected individually upon actuation of the stapler. A pusher assembly within the housing causes an individual strap to be expelled for passage through one end of a strap, piercing through the tissue and securement in the other end of the strap. Approximators with tissue engaging teeth are also used to bunch up the tissue about the incision during a stapling operation.

An endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating fastener applying assembly associated with a distal end of the elongated portion. The fastener applying assembly includes a base portion, a staple cartridge housing, and an anvil member which has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge housing. A first mechanism is provided for effectuating the rotation of the fastener applying assembly about an axis defined by the body portion, a second mechanism is provided for effectuating the articulation of the fastener applying assembly, and a third mechanism is provided for independently rotating the cartridge housing and anvil member relative to a longitudinal axis defined by the base position to increase the range of operability of the apparatus.

A seal assembly is provided which includes a gimbal-like structure permitting rotation of a mounting member relative to the housing. The rotation of the mounting member allows the seal member to align with an instrument being inserted therethrough. The seal assembly is adapted to be detachably mounted to a cannula assembly for use in endoscopic surgery.

The present invention provides endoscopic instrumentation and surgical techniques especially useful for accessing at least a portion of an intervertebral disc. Vertebrae spreading instruments are provided for spreading adjacent vertebrae to facilitate access to the intervertebral disc are. The disclosed surgical method uses an anterior approach to access the intervertebral disc and spreads adjacent vertebrae utilizing an endoscopic vertebrae spreading instrument.
摘要:
A compression device for the anastomosis of a tubular hollow organ, having a first collapsible member movable between an expanded configuration and a collapsed configuration, said first collapsible member having a first end and a second end; a second collapsible member movable between an expanded configuration and a collapsed configuration, said second collapsible member adapted to be joined with said first end of said first collapsible member; and a third collapsible member adapted to be joined with said second end of said second collapsible member; wherein at least one of said first, second or third collapsible members comprises at least one resilient hinge portion disposed thereon which is parallel to the longitudinal axis of said device to facilitate the collapsibility thereof. Also provided are surgical instruments for carrying and placing the compression device components and a device for approximating surgical devices. A method for forming a compression anastomosis, is also provided.

A method and apparatus for elevating, approximating and/or restraining internal organs or structures, and more particularly for treating female urinary stress incontinence are provided. The apparatus include an anchoring device having an elongated suture with an anchor at each end thereof and a cinching member therebetween for adjusting the operative length of the suture, an articulating apparatus for applying the anchoring device during an endoscopic or laparoscopic procedure, and an apparatus for drawing the suture relative to the cinching member after it has been emplaced.
摘要:
A device for driving surgical fasteners into tissue such as the menisci of the knee. The device essentially consists of a tubular housing member through which a piston shaft passes. The piston shaft extends at a first end and terminates in a gripping knob which facilitates retraction of the piston from the housing, and contacts a fastening member at a discharge end to drive the fastener from the device. A pivotable latching member engages the gripping knob when the piston arrangement is retracted against the force of the spring, and pivots to release the piston arrangement to fire the fastener.
摘要:
A detachable anvil rod for use with an apparatus for circular fastening of hollow organs is provided. An elongated rod member has a proximal end portion, a distal end portion and an irregular surface portion intermediate the proximal and distal end portions. The irregular surface portion includes a plurality of grooves which define a plurality of raised ridges. The ridges are adapted to engage grasping surfaces of a grasping tool so as to minimize potential of slippage, thus enhancing the maneuvering procedure of the anvil rod about the operative site. The anvil rod also includes a narrowly configured mounting portion which enables the rod to be applied to and mounted within the distal end of the stapling apparatus from a variety of angular positions. An apparatus which incorporates the improved detachable anvil rod is also described.
