    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.

    摘要翻译： 腹腔镜手术器具用于操纵远端腹腔镜手术器械。 手柄包括壳体，可枢转地附接到壳体的枢转手柄以及从壳体向外延伸的致动轴机构。 腹腔镜手术工具附着在与壳体相对的致动轴的远端。 致动轴机构通过用于操纵腹腔镜工具的枢转手柄的枢转运动在第一方向上纵向移动。 壳体承载的制动器允许轴沿第一方向纵向移动，同时限制轴沿第二相反方向的纵向移动。 附接到致动轴机构的拇指轮允许致动轴机构旋转以进一步操纵腹腔镜工具。

    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： Apparatus for applying at least one row of two-part surgical fasteners to body tissue, each surgical fastener having a pronged fastener portion for piercing body tissue, and an aperture retainer dimensioned and configured for engaged reception of the pronged fastener portion in interference fit therewith for gripping the body tissue therebetween. The apparatus includes means for holding a plurality of the fastener portions in generally aligned relation, means spaced from the fastener portion holding means for gripping body tissue therebetween and for releasably holding a plurality of the retainers in generally aligned relation and positioned opposite the fasteners when the body tissue is positioned therebetween. Means is provided for sequentially advancing the pronged fastener portions toward the apertured retainers to cause the fastener portions to pierce the body tissue and to be received within the apertures of the retainers in engaged interference relation so as to cause the fastener portions and the retainers to be engaged while gripping the body tissue therebetween. In the preferred embodiment a knife edge is provided to cut the body tissue midway between opposed pairs of rows of the fasteners as the fasteners are applied. A method for applying two spaced apart pairs of rows of the fasteners to body tissue on the apparatus of the invention is also disclosed.

    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.

    摘要： An endoscopic surgical stapling apparatus is disclosed. The apparatus comprises a frame and a generally elongated endoscopic section connected to the frame and extending distally therefrom. The endoscopic section includes a mechanism for storing a plurality of staples, a mechanism for advancing the staples for positioning adjacent body tissue and a mechanism for at least partially closing each staple. A low pressure pneumatic system disposed in the frame provides the forces to at least partially activate the staple advancing mechanism. The apparatus has particular application in attaching mesh to body tissue as in laparoscopic hernia repair.
