  • Patent number: 7891533
    Abstract: 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.

  • Patent number: 7866526
    Abstract: An apparatus for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue includes a frame and an elongated endoscopic section connected to the frame-and extending distally therefrom. A staple storage cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section. An elongated pusher system is provided for individually advancing at least one staple at a time distally. The pusher system includes a trigger system to actuate the pusher. The trigger system is provided with perceptible tactile sensing means to indicate when the legs of the staple being advanced are exposed so as to be visible to the user for positioning and orientation purposes.

  • Patent number: 7681772
    Abstract: An apparatus for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery includes an elongate member defining a longitudinal axis, a cartridge, an anvil, and a control member located in a proximal region of the elongate member. The cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. The anvil provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to body tissue. The control member is axially movable along the longitudinal axis to articulate the cartridge. The control member is also rotatable to rotate the cartridge.

  • Patent number: 7600663
    Abstract: A surgical fastening and cutting assembly having a housing defines a passage and a pusher, with a cam surface, slides in the passage. An arm couples to the housing and an anvil base is located on the arm. A body slides on the arm between the housing and the base. The body defines a bore and a staple passage having a staple therein. A cam follower extends from the cartridge body to the housing. In an open position, tissue can be placed between the anvil base and the body. In an intermediate position, the cam surface of the pusher can move the cam follower into a locked position and, thereby, the tissue can be clamped. In a fastened and cut position, the pusher can move such that the staple can be been driven and formed in the tissue and a knife, coupled to the pusher, can cut the tissue.

  • Publication number: 20090012537
    Abstract: A system is disclosed for securing a suture. The system includes a deformable suture clip having a pair of closely spaced panels configured for movement between an open position wherein a suture can pass between the two panels and a closed position wherein the suture can be securely clamped between the two panels. The system further includes a clip applicator having an elongated body defining opposed proximal and distal end portions. The distal end portion of the body includes a mounting fixture having structure for supporting the suture clip in an open position. The clip applicator further includes a mechanism for dislodging the suture clip from the mounting fixture, such that the panels of the clip move to the closed position to securely clamp the suture therebetween.

  • Patent number: 7278563
    Abstract: An instrument including a clamping jaw with an anvil defining an elongated slot and staple forming cups on opposing sides of the elongated slot. A housing rotatably mounts on the anvil and a pusher rotatably mounts within the housing. A handle actuates the clamping jaw from the open to the intermediate position by rotating the housing towards the clamping jaw. To move from the intermediate position to the closed position, the pusher rotates towards the anvil. A staple cartridge, disposed in the housing, includes a staple track for retaining two rows of staples on opposing sides of the elongated slot. Two staple drivers align with the distal most staples. The drivers slidably mount in the staple cartridge and couple to the pusher such that each staple driver forces a staple into the forming cups and, in turn, staples the body tissue as the pusher rotates from the intermediate to closed position.
