    摘要： A surgical apparatus is disclosed for attaching adjacent end portions of cutaneous body tissue wherein a pair of opposed jaws have means for moving the jaws toward and away from each other. Body tissue engaging means in the form of sharp tip members extend from each jaw and toward the other so as to engage the opposed portions of cutaneous tissue when the jaws are positioned thereagainst and moved toward each other. The jaws and the tips are arranged to cause the cutaneous tissue to assume an irregular shape at the interface whereby an elongated rod-like member, preferably rectangular in cross section, may be directed generally medially of the interface of the tissue to attach the opposed portions to thereby permit healing. The elongated member may have indentations to improve retention within the tissue. A tapered distal end of the elongated member has a pointed tip to facilitate penetration into the tissue.

    摘要： A handle for a laparoscopic instrument is provided for manipulating a distal laparoscopic tool. The handle includes a casing, a pivot handle pivotally attached to the casing, and an actuating shaft mechanism extending outward from the casing. Attached at the distal end of the actuating shaft opposite the casing is the laparoscopic surgical tool. The actuating shaft mechanism is longitudinally movable in a first direction by a pivotal movement of the pivot handle for manipulating the laparoscopic tool. A detent carried by the casing allows movement of the shaft longitudinally in the first direction while restraining longitudinal movement of the shaft in a second opposite direction. A thumb wheel attached to the actuating shaft mechanism allows the actuating shaft mechanism to be rotated for further manipulating the laparoscopic tool.

    摘要： A surgical apparatus for tightening a strap loop to a predetermined tension about split tissue portions includes a frame, an advancing mechanism for tightening the strap loop, a linkage mechanism which severs excess strap material not used in securing the tissue portions together and a control mechanism for controlling operation of the apparatus. The advancing mechanism includes a tensioning lever and a gear mechanism. The gear mechanism includes a tensioning hub and a clutch which releases when the tension in the strap loop exceeds a predetermined value. The control mechanism includes a safety feature for preventing inadvertent activation of the linkage mechanism. A buckle and a method for use with the surgical apparatus is also disclosed. The invention is particularly contemplated for repair of the human sternum when the sternum has been split during surgical procedures.

    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： A valve assembly adapted for introduction of an elongated object into a patient's body having a first valve formed of a resilient material and defining an aperture for reception of the object, the aperture being configured and dimensioned such that insertion of the object into the aperture will cause the resilient material defining the aperture to resiliently engage the outer surface of the object in a fluid tight manner. A second valve is positioned adjacent and distal of the first valve in general alignment therewith, whereby the second valve defines an aperture in general alignment with the aperture of the first valve, and is formed of a flexible material at least in the region defining the apeture. A pair of manually operable clamps are provided to selectively permit the aperture of the second valve to be opened or closed so as to permit entry of the object such that the object first passes through the first valve and then the second valve prior to entry into the patient's body.

    摘要： A bioabsorbable surgical fastener comprising a fastener member and an interlocking retainer member. The retainer member has longitudinally extending slots on the lateral sides of the retainer for allowing transverse expansion of the columnar members into which the prongs of the fastener member are locked. Fins on both the lateral and transverse sides of the prongs provide extra strength, and stability during implantation. Stopping surfaces prevent the fastener's barbed tip from exiting the opposite side of the retainer.
