    摘要： An improved surgical tool of the type comprising a handle assembly having a movable tool-operating handle member, a tool head having first and second tissue-engaging members movable between open and closed positions relative to one another, and a mechanism coupling the tool head to the handle assembly for causing opening and closing movement of the tissue-engaging members in response to manipulation of the movable tool-operating handle member. The improved tool is characterized by an inner shaft secured to a stationary part of the handle assembly, and a hollow outer shaft disposed in telescoping relation to the inner shaft, with the tool head being secured to the inner shaft and the outer shaft being movable axially relative to the inner shaft by manipulation of the movable tool-operating handle member, with the outer shaft causing opening and closing of the tissue-engaging members as it undergoes telescoping movement. Preferably an opaque tubular member surrounds the hollow outer shaft so as to conceal movement of the outer shaft. The tool also may include a manually-operated mechanism for selectively rotating the tool head relative to the handle assembly.

    摘要： A bone fastener including an expandable member having an axial channel and an elongated element insertable into the axial channel is described. The expandable member is configured to be insertible into a bore drilled in bone. The distal end of the expandable member also may include a structure for axially releasing the expandable member from an emplacement device that places the expandable member into a bone opening. In one embodiment, the structure for axially releasing includes a frangible membrane capable of being severed from the expandable member during emplacement of the expandable member in a bone opening. A rivet for coupling an object to bone for use with an expandable member is also described. The distal end of the elongated element is shaped into a radially projecting portion adapted for engagement with a washer that contacts the object to be coupled. The washer, having upper and lower surfaces and a bore defined between the surfaces, is disposed around a portion of the shaft. The elongated element is adapted for movement independent of the washer since the radial projection of the element has a different radius of curvature than the washer. An apparatus for use within an endoscope is described. The apparatus includes an elongated, substantially hollow holding means for emplacing a bone fastener of the invention in a bone opening. The expandable member includes a structure for axially releasing the expandable member from the holding means. A method of attaching soft tissue to bone is also described. The invention also includes a surgical fastener kit.

    摘要： A bone fastener for fixing either a suture or a rivet within a predrilled bone hole includes an expandable sleeve having an axial bore and a pin forcibly insertible into the axial bore, the expandable sleeve being configured to be insertible into a bore drilled in bone, at least a portion of the pin having an outer diameter greater than the inner diameter of at least a portion of the axial bore. The fastener is emplaced by inserting the sleeve into a predrilled hole in the bone, and then forcing the pin into the axial bore, so that the wider portion of the pin presses outward against and expands the narrower portion of the sleeve, causing the sleeve to forcibly contact the walls of the bone hole and fixing the pin and sleeve firmly in place within the hole. Also, apparatus for emplacement of such a fastener includes a holder for holding the expandable sleeve in position within the predrilled hole in the bone, and a plunger moveable in relation to the holder for forcing the pin into the bore, so that the pin can be forced into the axial bore without imposing substantial net forces toward or away from the bone.
