    Abstract: 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.

    Abstract: A method for anchoring suture to bone, wherein the method comprises the steps of (1) providing a suture anchor of the sort comprising (a) a coupling member, (b) at least one barb, said barb having a first end and a second end and being curved in its normal unstressed state and being capable of being elastically deformed to a substantially straight configuration, said barb being attached to said coupling member so that said second end of said barb is substantially displaced from said coupling member when said barb is in its normal unstressed state but is aligned with said coupling member when said barb is deformed to a substantially straight configuration, and (c) attachment means for attaching the suture to the suture anchor, (2) deforming the barb to a substantially straight configuration and retaining the barb in its deformed condition, and attaching a suture to the suture anchor, and forming a hole in a bone to which the suture is to be anchored, (3) inserting the suture anchor with its deformed barb into the hole in the bone, and (4) releasing the barb from its deformed condition while the suture anchor is disposed in the hole, whereby the barb will restore itself to its normal curved state so as to fix the suture anchor and hence the suture to the bone.
