Abstract
A method of forming a channel in a bone, the method comprising: providing a first bore in the bone; and forming, a second bore in the bone at a predefined angle from said first bore, using said first bore as a reference point for defining the location of the second bore in the bone, wherein the first and second bores intersect in the bone.
Claims35
A medical implement for attaching a suture to a bone, comprising:
- a handle having a proximal end for manual grasping and a distal end for engagement with said bone to which said suture is to be attached, said bone being pre-formed with a first bore, said handle extending axially from said proximal end to said distal end;
- a hook extending from the distal end of the handle and configured for reception in said first bore of the bone;
- a movable member resiliently coupled to said handle and urged in an axial direction of the handle toward the hook responsive to the resilient coupling, said movable member being movable to a retracted position with respect to the hook to facilitate reception of the hook into said first bore, and biased to an extended position with respect to the proximal end of the handle for clamping said handle to said bone with a resilient force at a predetermined angle with respect to said first bore;
- and a manually manipulatable member coupled to said movable member for moving said movable member to said extended and retracted positions;
- said handle being formed with a passageway extending longitudinally therethrough from its proximal end to its distal end, said passageway being configured for receiving a drill, for drilling a second bore through said bone at said predetermined angle with respect to said first bore and for passing through the passageway 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.

A medical implement, comprising:
- a hook that is formed from a single piece with a bend to hook a first bore in a bone;
- a passageway for placement at an entrance to a second bore in the bone;
- and
- a grasper extending from the hook, said grasper being adapted to grasp an end of a suture inserted through the passageway and through the second bore,
- wherein said passageway is movable by retraction or extension of a resilient member towards and away from said hook.
2 more elements
A medical implement comprising:
- an elongate element comprising a proximal end for manual grasping and a distal end for engagement with a bone;
- a first passageway formed in the elongate element and extending from said proximal end to said distal end of the elongate element;
- and
- a hook formed in said distal end of the elongate element capable of slidably inserting into a straight bore in the bone,
- wherein at least one of the hook and a part of the elongate element formed with the first passage way is movable by retraction or extension of a resilient member from a retracted position to an extended position along or parallel to an axis of said elongate element and wherein the hook, the part of the elongate element and the resilient member provide for clamping the bone with a resilient force, wherein the resilient member is urged in an axial direction of the elongate element toward the distal end of the elongate element responsive to the resilient member.
