Description

Technical Field

[0001] This utility model relates to the field of medical anchor technology, specifically an orthopedic medical anchor. Background Technology

[0002] In the field of sports medicine, anchors are an important medical device widely used in joint repair surgeries such as shoulder, knee, and ankle. During the surgery, sports medicine anchors are usually vertically implanted into the bone surface of the injured area and fixed in the bone by means of threads or expansion wings. With the help of sutures or bandages, the soft tissue is firmly fixed to the bone surface, thereby maintaining a stable position until healing.

[0003] Currently, after doctors finish suturing with sutures, they tie the sutures into knots and then pull them tight. The suture ends are directly exposed on the surface of the soft tissue. During the soft tissue healing process, the soft tissue will directly wrap around the suture ends, and there is a risk that the suture ends will loosen. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an orthopedic medical anchor that has the advantage of embedding the suture end within the anchor cavity, thus avoiding the problem of the suture end being exposed on the outside of soft tissue.

[0005] To achieve the goal of embedding the wire end within the anchor cavity, this utility model provides the following technical solution:

[0006] An orthopedic medical anchor includes a steel plate, wherein multiple insertion holes are formed on the sidewall of the steel plate, and an anchor body is threadedly connected to the sidewall of the steel plate. It also includes:

[0007] The anchor body includes an implantation part and a connecting part. The connecting part is threadedly connected to a steel plate, and the implantation part penetrates the steel plate. The top of the anchor body has a threaded hole, and a fixing bolt is threadedly connected to the inner wall of the threaded hole. The side wall of the implantation part has a first thread hole, and the side walls of the connecting part and the fixing bolt both have second thread holes. A suture is engaged between the first thread hole and the second thread hole. The inner cavities of the first thread hole and the second thread hole are threadedly connected to threaded bolts, and the threaded bolts can extend into the inner cavity of the implantation part and the inner cavity of the fixing bolt, respectively.

[0008] According to some embodiments, the sidewall of the implanted portion is fixedly connected with a first thread, the sidewall of the connecting portion is fixedly connected with a second thread, the diameter of the connecting portion is larger than the diameter of the implanted portion, the top of the connecting portion is provided with a slot, and the top of the fixing bolt is provided with a locking hole.

[0009] Beneficial effects

[0010] This utility model provides an orthopedic medical anchor with the following beneficial effects:

[0011] This orthopedic medical anchor places one end of a suture in the cavity of the implantation site and then extends it deep into the bone. The suture is used to suture the soft tissue. The other end of the suture is then fixed in the cavity of the anchor. Rotating the anchor causes the suture to move deeper into the cavity of the anchor body, thereby tightening the suture to fix the soft tissue. The excess part of the suture is in the cavity of the anchor body, while preventing the suture end from being directly exposed. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-6 An orthopedic medical anchor includes a steel plate 1, with multiple insertion holes 101 on the side wall of the steel plate 1, and an anchor body 102 threadedly connected to the side wall of the steel plate 1. It also includes:

[0021] The anchor body 102 includes an implantation part 2 and a connecting part 201. The connecting part 201 is threadedly connected to the steel plate 1. The implantation part 2 penetrates the steel plate 1. The top of the anchor body 102 has a threaded hole 202. A fixing bolt 203 is threadedly connected to the inner wall of the threaded hole 202. The side wall of the implantation part 2 has a first thread hole 204. The side walls of the connecting part 201 and the fixing bolt 203 both have a second thread hole 205. A suture 206 is snapped between the first thread hole 204 and the second thread hole 205.

[0022] Both the first threading hole 204 and the second threading hole 205 are threadedly connected to threaded bolts, and the threaded bolts can extend into the inner cavity of the implantation part 2 and the inner cavity of the fixation bolt 203, respectively.

[0023] It should be noted that: one end of the suture 206 is placed in the cavity of the first suture hole 204 and then fixed with a threaded bolt. The steel plate 1 can be fixed to the bone using the anchor body 102, wherein the implanted part 2 extends deep into the bone, and the connecting part 201 is partially exposed on the outside of the steel plate 1. The soft tissue can then be sutured using the suture 206. After that, the other end of the suture 206 is inserted into the cavity of the fixation bolt 203 through the second suture hole 205. At this time, the other end of the suture 206 can be fixed in the cavity of the fixation bolt 203 using a threaded bolt. Then, the fixation bolt 203 is rotated, which will drive the suture 206 to move deeper into the cavity of the anchor body 102, thereby tightening the suture 206 so that the suture 206 fixes the soft tissue. The excess part of the suture 206 is in the cavity of the anchor body 102, while ensuring that the suture end of the suture 206 is not directly exposed.

[0024] Reference Figures 1-6 The implanted part 2 has a first threaded tooth 3 fixedly connected to its side wall, and the connecting part 201 has a second threaded tooth 301 fixedly connected to its side wall. The diameter of the connecting part 201 is larger than the diameter of the implanted part 2.

[0025] The top of the connecting part 201 is provided with a slot 302, and the top of the fixing bolt 203 is provided with a hole 303;

[0026] It should be noted that: the first thread 3 on the side wall of the implant part 2 facilitates its extension into the deep bone, the second thread 301 on the connecting part 201 facilitates the fixation of the steel plate 1, the slot 302 facilitates the rotation of the anchor body 101, and the slot 303 on the top of the fixation bolt 203 facilitates the rotation of the fixation bolt 203.

[0027] Operation method: Place one end of the suture 206 into the cavity of the first suture hole 204, and then fix it with a threaded bolt. The steel plate 1 can be fixed to the bone with the anchor body 102. The implanted part 2 extends deep into the bone, and the connecting part 201 is partially exposed on the outside of the steel plate 1. The soft tissue can then be sutured with the suture 206 of the implanted part 2.

[0028] Next, insert the other end of the suture 206 into the inner cavity of the fixation bolt 203 through the second thread hole 205. At this time, the other end of the suture 206 can be fixed in the inner cavity of the fixation bolt 203 using a threaded bolt. Then, rotate the fixation bolt 203, which will drive the suture 206 to move deeper into the inner cavity of the anchor body 102, thereby tightening the suture 206 so that the suture 206 can fix the soft tissue. The excess part of the suture 206 is in the inner cavity of the anchor body 102, while ensuring that the end of the suture 206 is not directly exposed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
