MEDICAL APPARATUS AND METHOD FOR ATTACHING A SUTURE TO A BONE

摘要

The present invention relates to a medical implement (100) for attaching a suture to a bone, comprising: a handle (120) having a proximal end (121) for manual grasping and a distal end (122) for engagement with a bone to which a suture is to be attached, said bone being pre-formed with at least one first bore, said handle (120) extending longitudinally from said proximal end (121) to said distal end (122); a hook (130) carried at said distal end (122) of the handle (120), spaced from an outer surface at said distal end (122) of the handle (120), and configured for reception in said first bore of the bone; a movable member (123) resiliently coupled with a spring (124) to said handle (120) and urged to extend longitudinally from said distal end (122) of the handle (120) to an extended position responsive to said resilient coupling, wherein said movable member (123) is movable between said extended position and a retracted position, wherein in said retracted position said movable member (123) is retracted away from said hook (130) to facilitate reception of said hook (130) into said first bore, and in said extended position said movable member (123) is extended toward said hook (130) to engage said bone for clamping said handle (120) to said bone at a predetermined angle with respect to said first bore while said hook (130) is in said first bore; and a manually manipulatable member (126) coupled to said movable member (123) for moving said movable member (123) between said extended and retracted positions; said handle (120) being formed with a passageway (20a) extending longitudinally therethrough from its proximal end (121) to its distal end (122), said passageway (20a) being positioned with respect to said hook (130) for receiving a drill (54), for drilling a second bore through said bone at said predetermined angle with respect to said first bore and for passing through the passageway (20a) one end of a suture to traverse, and to extend past, said first bore such that said one end of the suture is accessible through said first bore for being pulled out therefrom, while the opposite end of the suture is accessible through said second bore for pulling out therefrom in order to attach the suture to said bone.
