摘要： A surgical clip applier comprising a housing, a pair of handles pivotally connected to opposite sides of the housing, and a jaw blade assembly fixedly connected to the housing. The jaw blade assembly includes a pair of jaws for receiving and deforming a clip therebetween and a clip carrier for supplying a series of clips to the jaws. A channel assembly is slidably mounted with respect to the housing and envelops the jaw blade assembly for camming the jaws closed upon closing of the handles. The clips may be fed to the jaws by a spring biased feed bar which operates upon closing of the handles, or may be urged by pusher bar which provides a biasing force to the clips to be retained by the jaws. The instrument may be used in conventional surgical procedures, or may be adapted for endoscopic and laparoscopic surgical procedures requiting the application of microsurgical clips.

摘要： A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod. The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod. An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site. The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.

摘要： An apparatus and surgical staple are disclosed for endoscope application of the surgical staples for attaching surgical mesh to body tissue in laparoscopic hernia surgery. The surgical staple is formed of a length of wire having a central portion having a middle portion and end portions extending therefrom in a first direction. Wire leg members extend in a direction generally perpendicular to the middle portion. Bridge portions are provided to connect each leg member to the end portions of the central portion. The bridge portions each have a straight portion substantially parallel to the middle portion and extending away from the end portions of the central portion. A first generally arcuate portion connected to the straight portions has a concave surface portion facing in a direction generally inwardly toward the opposing leg member. The first generally arcuate portions are connected to the leg members and at least a portion of each arcuate portion extends from the straight portions and generally in the first direction. A second arcuate portion on the leg members connects the leg member to the first arcuate portion. The free ends of the leg members are sharp to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue.
