Specifically, a traction line and an outer-row nail body are prefabricated in a preformed knotted disk, and the inner-row anchor suture is introduced into the passage of the preformed knotted disk by using the traction line, so that the inner-row anchor suture replaces the traction line and is inserted into the outer-row nail body, and a knot-free structure is formed when it is turned back, thereby solving the problem that the inner-row anchor suture is difficult to introduce into the outer-row nail body composed of full sutures, and knot-free can be achieved at the same time; during the operation, it is only necessary to connect the inner-row anchor suture to the wire loop end of the traction line, and the free end of the traction line is pulled to complete the two operations of introducing the inner-row anchor suture into the outer-row nail body and forming the knot-free structure at one time, thereby simplifying the surgical operation and saving the surgical time. At the same time, the multi-directional routing of the inner-row anchor suture in the outer-row nail body and the knotting in the bone canal ensure the fixing stability of the full-suture outer-row anchor to the inner-row suture.

Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a manufacturing method of a full-suture outer-row anchor assembly and the full-suture outer-row anchor assembly. Background Art

[0002] Wire anchors are important tools in bone and joint surgery. Their main function is to fix soft tissues such as ligaments or tendons to bone tissue to form a reliable bone fixation point, thereby providing stable support.

[0003] According to the different functions of the wire anchors, they can be divided into inner row nails, outer row nails and individually fixed anchors. The inner row nails usually have their own sutures. After being firmly connected to the bone through the anchors, the free ends of the sutures are passed through the outer row nails and fixed to the bone. The outer row nails usually do not have their own sutures. The surgical effect is achieved by introducing the inner row nail sutures and fixing them in the bone canal. After the individually fixed anchors are implanted in the bone canal, the sutures they carry are used to tie or surround the soft tissue to achieve tissue fixation.

[0004] The full suture anchor is a type of anchor with a wire. It is characterized by the fact that the full suture anchor is connected to the suture by a flexible full suture anchor instead of a rigid material anchor. After being implanted into the bone tunnel, the full suture anchor is deformed and expanded by tightening the suture to form a firm connection with the bone. Its advantages are that the full suture anchor is small in size, has a small amount of bone removal, does not extensively damage the bone joint surface, is soft in texture, avoids accidental damage to surrounding tissues, and does not interfere with medical imaging examinations.

[0005] The current full-suture anchor products are mainly inner row anchors and single fixed anchors, and the technology of full-suture anchors applied to the field of external row fixation has not yet been disclosed. The main reasons are: ① It is difficult to introduce the sutures carried by the inner row fixed anchors into the flexible outer row full-suture anchors during surgery. The full-suture anchors are easy to detach from the inserter or deform or even fall apart, affecting the implantation operation and fixation effect; ② After the external row fixation is completed, the ends of the sutures will be cut off, the sutures are unilaterally stressed and the connection with the full-suture anchor is weak. If there is no strong knot structure, it is easy to slip at the knot after stress, resulting in failure of the operation; ③ If the final fixation is achieved by knotting, on the one hand, the knotting process under arthroscopy is complicated and has high requirements for the doctor's operating experience; on the other hand, the location of the knot is often on the bone surface, which is a certain distance away from the full-suture anchor in the bone canal, which will cause the knot to be unstable and the anchor to be loose.

[0006] Therefore, a method for manufacturing a full-suture outer-row anchor assembly that can use full-suture anchors for outer-row fixation and a full-suture outer-row anchor assembly are urgently needed. Summary of the invention

The inner row anchor suture 12 introduced during the operation is pre-knotted, and the knot is tightened after implantation to achieve the function of outer row fixation; the setting of the above pre-knotted disk 1 makes the traction line 9, the outer row nail body 10 and the inserter 11 maintain a relatively stable match. During the operation, it is only necessary to pass the inner row anchor suture 12 through the wire loop end of the above traction line 9, and then pull the free end of the above traction line 9 to complete the assembly of the inner row anchor suture 12 and the outer row nail body 10, and then alternately pull the free end of the inner row anchor suture 12 and the above traction line 9. The pull ring 26 can complete the tightening and self-locking of the outer row of nail bodies 10, and has excellent operational convenience; after the inner row of anchor sutures 12 are tightened into a knot, the first wire loop 17 compresses the outer row of nail bodies 10, causing the outer row of nail bodies 10 to be squeezed and deformed, and the second wire loop 18 and the third wire loop 19 tighten and fix the two free ends of the inner row of anchor sutures 12 respectively, so that the self-locking knot can play a firm fixing role, and the outer row of nail bodies 10 and the inner row of anchor sutures 12 are tightened and formed under tension to produce a plasticizing effect, and the fixing performance will be further improved after long-term implantation.

[0059] The above is only a specific implementation of the invention, but the protection scope of the invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the invention should be included in the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope of the claims.
