ORTHOPEDIC ANCHOR AND SURGICAL TOOL INTEGRATED WITH ANCHOR FASTENING MEMBER

1 . A surgical tool having an integrated orthopedic anchor and anchor coupler, the surgical tool comprising:

an anchor having a cylindrical anchor body that has threads on an outer surface thereof,

an anchor coupling portion-insertion groove that is formed in the cylindrical anchor body inward from a rear surface of the cylindrical anchor body, and

through-holes that are formed through both sides of a front end of the anchor body from the anchor coupling portion-insertion groove to form a suture hook and has arc recessions formed on an inner surface thereof and angulated recessions formed on an outer surface thereof; and

an anchor coupler having

an anchor coupling portion that is formed at a front end of a hollow rod to correspond to the anchor coupling portion-insertion groove of the anchor and is fitted in the anchor coupling portion-insertion groove,

protruding front end portions that are laterally separated at a front of the anchor coupling portion, are inserted in the through-holes at both sides of the front end of the anchor body to protrude from the through-holes, have arc recessions formed on inner surface thereof to face the arc recessions formed on the inner surfaces of the through-holes of the anchor body, and have angulated outer surfaces formed on outer surface thereof to correspond to the angulated recessions formed on the outer surfaces of the through-holes of the anchor body, and

a handle that is formed at a rear end of the hollow rod to be used to rotate the rod and has a suture holder being able to fix an end of a suture passing through the rod,

wherein the anchor and the anchor coupler are integrated; when the anchor is coupled and fixed to the anchor coupling portion of the anchor coupler, the arc recessions formed at the through-holes on both sides of the front end of the anchor body and the arc recessions formed at the anchor coupling portion are fitted to each other, so suture insertion holes aligned with holes in the anchor coupling portion and having wide inlets are formed and the suture is easily connected;

when the anchor coupler is rotated and pressed in surgery, the protruding front ends separated at the anchor coupling portion and protruding through the through-holes at both sides of the front end of the anchor body bore a bone tissue while covering an outer surface of the front end portion of the anchor; and

damage to the protruding front end portions and the anchor is prevented due to thread-fastening of the anchor.

2 . The surgical tool of claim 1 , wherein the protruding front ends formed at both side of the front end of the anchor coupling portion of the anchor coupler are formed to be pointed forward when seen from a side to easily bore a bone tissue.

3 . The surgical tool of claim 1 , wherein the angulated outer surfaces are each formed in a “>” shape when the protruding front ends formed at both side of the front end of the anchor coupling portion of the anchor coupler are seen from the front, so when the protruding front ends bore a bone tissue, the protruding front ends are smoothly inserted into the bone tissue without excessively pressing the bone tissue due to reduction of friction resistance against rotation, whereby the bone tissue is not damaged and the protruding front ends are not broken.

4 . The surgery tool of claim 1 , wherein a dense thread portion having a gap (pitch) smaller than the threads at a front portion of the anchor body of the anchor is formed on the outer surface of a rear portion of the anchor body so that a fastening force by the dense thread portion is increased and the anchor is firmly thread-fastened in a bone tissue without loosening.
