BEST MODE

[0063] Hereafter, embodiments of the present disclosure for achieving the objectives described above are described with reference to the accompanying drawings. The following embodiments are only example for helping understand the present disclosure and it should be understood that the present disclosure may be modified in various ways different from the embodiments described herein. However, in describing the present invention, detailed descriptions and drawings of well-known functions or components relating to the present disclosure will not be provided so as not to obscure the description of the present disclosure with unnecessary details. Further, the dimensions of some components are not shown with the actual scales and may be exaggerated in the drawings to help understand the present disclosure.

[0064] A surgical tool having an integrated orthopedic anchor and anchor coupler of the present disclosure, as shown in FIGS. 1 to 4, in a broad meaning, includes an anchor 100 that is thread-fastened and fixed in a bone tissue 30 with a suture 10 connected thereto, and an anchor coupler 200 that is used to thread-fasten the anchor 100 in a bone tissue by rotating the anchor 100.

[0065] The reason of integrating the orthopedic anchor and the anchor coupler is because the anchor and the anchor coupler discharge their duties in one-time use and cannot be reused due to sanitary reasons such as a possibility of infection.

[0066] First, the anchor 100 proposed herein is described.

[0067] An anchor body 110 of the anchor 100 has threads 111 on the outer surface.

[0068] The cylindrical anchor body 110 further has an anchor coupling portion-insertion groove 120 and the anchor coupling portion-insertion groove 120 is formed in the anchor body 110 inward from the rear surface of the anchor body 110.

[0069] Through-holes 130 are further formed in the cylindrical anchor body 110. The through-holes 130 are formed through two sides of the front end of the anchor body 110 from the anchor coupling portion-insertion groove 120, whereby a suture holder 131 is formed.

[0070] An arc recession 130a is formed on the inner surface of the through-hole and an angulated recession 130b is formed on the outer surface of the through-hole.

[0071] The anchor coupler 200 proposed herein is described hereafter.

[0072] The anchor coupler 200 has an anchor coupling portion 220 at the front end of a hollow rod 210. The anchor coupling portion 220 has a shape corresponding to the anchor coupling portion-insertion groove 120 of the anchor 100 so that torque can be transmitted to the anchor 100.

[0073] Both of the anchor coupling portion 220 and the anchor coupling portion-insertion groove 120 have a hexagonal shape in the present disclosure, but they are not limited thereto.

[0074] The anchor coupler 200 further has a pair of protruding front end portions 221 and the protruding front end portions 221 are laterally separated at the front of the anchor coupling portion 220.

[0075] The protruding front end portions 221 are cut to be slightly pointed forward when seen from a side.

[0076] The protruding front end portions 221 extending forward from the anchor coupling portion 220 are inserted in the through-holes 130 formed on both sides of the front end of the anchor body 110 such that both ends thereof protrude from the through-holes 130 to bore a bone tissue 30.

[0077] An arc recession 221 is formed on the inner surface of the protruding front end portion 221 to face the arc recession 130a formed on the inner surface of the through-hole 130 of the anchor body 110. Further, an angulated outer surface 221b is formed in a “>” shape on the outer surface of the protruding front end portion 221 to correspond to the angulated recession 131b on the outer surface of the through-hole 130.

[0078] Accordingly, since the protruding front end portions 221 are formed to be slightly pointed forward when seen from a side and the angulated outer surfaces 221b are each formed a “>” shape when seen from the front, the bone tissue 30 can be easily bored by the protruding front end portions 221. Further, since friction resistance against to rotation is decreased, the protruding front end portions 221 are smoothly inserted into the bone tissue 30 under pressure without excessively pressing the bone tissue 30, so damage to the bone tissue 30 is prevented.

[0079] Since excessive pressure is not applied, damage such as breakage of both protruding front end portions 221 is completely prevented.

[0080] Meanwhile, a handle 230 for rotating the hollow rod 210 is formed at the rear end of the rod 210. A suture holder 231 that can fix an end of a suture 10 connected to the anchor and passing through the rod 210 is formed in various shapes on the handle 230.

[0081] As described above, the surgical tool having an integrated orthopedic anchor and anchor coupler of the present disclosure has a structure having specific configuration.

[0082] Accordingly, when the anchor 100 is coupled and fixed to the anchor coupling portion 220 of the anchor coupler 200, the arc recessions 131a formed at the through-holes 130 on both sides of the front end of the anchor body 110 and the arc recessions 221a formed at the anchor coupling portion 220 are fitted to each other. Accordingly, suture insertion holes 20 aligned with holes in the anchor coupling portion 220 and having wide inlets are naturally formed.

[0083] Accordingly, it is possible to connect the suture 10 first to the anchor 100 and then couple the anchor 100 with the suture 10 connected thereto to the anchor coupler 200. Further, it is possible to couple the anchor 100 to the anchor coupler 200 and then connect the suture 10. That is, the suture 10 can be freely selectively connected, and the suture 10 can be very simply and quickly connected regardless of using any ways.

[0084] Further, according to the present disclosure, the protruding front end portions 221 laterally separated at the front end of the anchor coupling portion 220 are fitted to the through-holes 130 on both sides of the front end of the anchor body 110 such that only a portion of each of the front ends protrudes from the front end of the anchor 100. Accordingly, when a user rotates and presses the anchor coupler 200 by holding and rotating the handle 230 in surgery, the protruding front end portions 221 first bore the bone tissue 30. Further, since the anchor 100 can be thread-fastened, the anchor 100 can be very simply and quickly implanted.

[0085] Further, since only a portion of each of the front ends of the protruding front end portions 221 protrudes outward, the protruding front end portions 221 are formed to be slightly pointed forward when seen from a side, and the angulated outer surfaces 221b are formed a “>” shape when seen from the front, the bone tissue 30 can be easily bored. Further, since friction resistance against to rotation is decreased, the protruding front end portions 221 are smoothly inserted into the bone tissue 30 under pressure without excessively pressing the bone tissue 30, so damage to the bone tissue 30 can be prevented.

[0086] Further, since excessive pressure is not applied, damage such as breakage of both protruding front end portions 221 is completely prevented.

[0087] Meanwhile, a dense thread portion 111a having a gap (pitch) smaller than the threads at the front portion of the anchor body 110 of the anchor 100 are formed on the outer surface of the rear portion of the anchor body 110.

[0088] Accordingly, when the anchor 110 is thread-fastened in the bone tissue 30, the fastening force is increased by the dense thread portion 111a, so the anchor 100 is firmly thread-fastened in the bone tissue without loosening.

[0089] Therefore, it is possible to more safely bond a muscle or a ligament to the bone by pulling the suture 10 connected to the anchor.

[0090] Although the present disclosure was described with reference to limited exemplary embodiments and drawings, the present disclosure is not limited thereto and may be changed and modified in various ways within the spirit of the present disclosure and claims described below by those skilled in the art.

INDUSTRIAL APPLICABILITY

[0091] The surgical tool having an integrated orthopedic anchor and anchor coupler according to an embodiment of the present disclosure can be used to firmly fix an anchor in a bone tissue in orthopedic surgery.
