Description

Technical Field

[0001] This invention relates to the field of suture anchor structure technology, and more specifically, to a fully suture anchor and its processing method. Background Technology

[0002] Traditional anchors typically rely on mechanical embedding or spiral fixation to provide stability, but these methods may have the following problems: rigid anchors may damage bone or soft tissue; some designs are beginning to use braided structures, where the anchors can be fixed by the tension of the sutures after implantation;

[0003] However, existing braided anchors still have certain limitations, such as insufficient fixing force and poor stability. Therefore, a fully sewn anchor and its processing method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a fully stitched anchor and its processing method, thereby solving the problem of poor displacement stability of fully stitched anchors after long-term use in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A fully sewn anchor, comprising an anchor body and sewn thread;

[0007] The nail body is made of woven stitches, including flat woven stitch structures and hollow woven stitch structures;

[0008] The thread is a braided hollow thread, including adjustable loops, movable traction parts, and pull-out parts;

[0009] Adjustable coil, the stitching segment of the adjustable coil passes through the nail body;

[0010] The adjustable coil is formed by two closed loop structures through which the suture segment passes through its own hollow structure, and the two adjustable coils pull each other.

[0011] A movable traction unit is located at both ends of the adjustable coil and is used to adjust the length of the adjustable coil.

[0012] The beneficial effects of this invention are:

[0013] 1. By connecting the suture and the nail body through a back-and-forth threading process, multiple self-locking friction nodes are formed, achieving continuous and graded fixation, increasing the fixing force of the suture anchor, and preventing suture slippage;

[0014] 2. By connecting the sutures within the body, multiple movable traction sections are formed, enabling the sutures to be pulled out and self-locked at any time. This eliminates cumbersome surgical procedures and helps improve the convenience and success rate of the surgery. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The purpose of this invention is to overcome the problem of poor displacement stability of fully threaded anchors after long-term use in existing technologies. To achieve the above objective, this invention provides a multi-body fully threaded anchor, such as... Figure 1-4 As shown, it includes a nail body 1 and a suture 2;

[0028] Nail body 1 is a braided structure, comprising two bodies: nail body one 101 and nail body two 102;

[0029] The braided structures include flat stitch braided structures and hollow stitch braided structures;

[0030] The sewing thread 2 is a hollow braided thread, including an adjustable coil, a movable traction part, and a pull-out part;

[0031] The adjustable coil includes two closed-loop structures, namely ring sleeve one 21 and ring sleeve two 22, which are connected to the nail body 1 by a reciprocating through-wire connection.

[0032] The closed-loop structure is formed by the suture 2 passing through its own hollow structure, and the suture connection part forms a movable traction part, thus forming two adjustable coils that pull each other.

[0033] The movable traction part is used to adjust the length of the adjustable coil, that is, to control the thread connection length between the suture 2 and the nail body 1;

[0034] Furthermore, the movable traction part is distributed at both ends of the nail body 1. One end is a movable channel formed by the thread segment of the suture 2 passing through the hollow structure of the suture 2 itself, including thread channel one 301 and thread channel two 302. The movable traction part located at the other end of the nail body 1 establishes thread channel three 303 in the same way, or the two thread segments of the suture 2 cross and are folded to form an interlocking connection.

[0035] It should be noted that the movable traction part is controlled by the pull-out part. The pull-out part is the part of the thread 2 that extends outward after the thread end passes through its own hollow structure to form an adjustable coil. The pull-out part controls the thread segment of the thread 2 to be pulled inside the hollow structure of the thread 2, thereby pulling the adjustable coil to contract and adjust the length.

[0036] When in use, the nail body 1 is placed into the fixing hole. By pulling the thread 2, the length of the adjustable coil is reduced, so that the nail body 1 shrinks into a ball and comes into contact with the inside of the fixing hole to complete the fixation.

[0037] It is understandable that the connection method between the adjustable coil and the nail body 1 is related to the braided structure of the nail body 1;

[0038] When the nail body 1 is a flat braided stitch structure, the adjustable loops are interlaced and pass through the nail body;

[0039] When the nail body 1 is a hollow braided stitch structure, the adjustable coil passes through the hollow structure.

[0040] The specific structure of this disclosure can be as follows: Figure 1 As shown, in some public implementations, a fully sutured anchor includes a nail body 1 and a suture 2;

[0041] Both loop 21 and loop 22 of the suture 2 include a threading section and a movable section;

[0042] Among them, the threading segment is divided into threading body one 211 and threading body two 221, which are the threading segments of ring one 21 and ring two 221 connected to the nail body 1;

[0043] Furthermore, the movable segment is the line segment of the thread 2 that is pulled towards one end of the nail body 1 after it passes through the center point K5 at the other end of the nail body 1, which is the line segment connected to the thread 2 of the pull-out part.

[0044] Furthermore, when the active segment is pulled from the center point K5 to one end of the nail body 1, it is connected to the nail body 1 101 and the nail body 2 102 in a back-and-forth through-threading manner, forming the first folding threading segment 212 and the second folding threading segment 222 respectively.

[0045] It is understandable that the stitch 2 and the nail body 1 are connected by a back-and-forth threading method to form a multi-segment oblique anchoring structure, and the cross-section of the adjacent anchoring segments is shaped like the number "8".

[0046] In some public, such as Figure 1 and Figure 2 As shown, the overall length of the nail body 1 is 12-36mm, and the suture 2 passes through the other end of the nail body 1, with the exit point being the center point K5;

[0047] From one end of the nail body 1 to the center point K5, there are four threading points, namely K1, K2, K3 and K4.

[0048] Furthermore, the angle at which the suture 2 enters the nail body 1 from the threading point is 20 degrees, the distance between point K1 and the end face of the nail body 1 is L1, the distances between K1 and K2, K2 and K3, and K3 and K4 are L2, L3 and L4 respectively, the distance between K4 on both sides of the center point K5 is L5, and the ratio of distances L1:L2:L3:L4:L5 is 2:3:2:3:2;

[0049] In some embodiments, the angle at which the suture 2 enters the nail body 1 from the threading point is 60 degrees, and the distance ratio of L1:L2:L3:L4:L5 is 2:5:2:5:3.

[0050] In some public, such as Figure 4As shown, the first folding thread segment 212 and the second folding thread segment 222 are inserted into the nail body 1 to form threading points K6 and K7. The distance from the center point K5 to K6 is L6, and the distance between K6 and K7 is L7.

[0051] Among them, K6 is located on the adjacent side of the two bodies of nail 1, between K3 and K4 and adjacent to K4;

[0052] K7 is located on the opposite side of the two bodies of nail 1, between K1 and K2 and adjacent to K2.

[0053] like Figure 5-8 As shown, in some embodiments, the thread connection structure between the suture 2 and the nail body 1 can also be as follows: Figure 5-8 As shown;

[0054] Among them, C1 and C2 are the two main bodies of nail body 1, which are either an integral structure or a separate structure;

[0055] Furthermore, A and B are the two ends of suture 2;

[0056] In addition, T1, T2, and T3 are the active channels established inside suture 2;

[0057] In addition, H1 and H2 are the thread segments that connect with C1 and C2 when the suture 2 is pulled back.

[0058] In some publicly available information, the specific processing steps for full-stitch anchors are as follows:

[0059] S1: Forward threading of the suture 2 and the nail body 1;

[0060] S11: The A end and B end of the suture are pulled from one end of nail body C1 and nail body C2 to the other end, respectively, and the suture is connected by passing back and forth through nail body C1 and nail body C2 during the process;

[0061] S2: Processing of the movable traction part of the suture 2, immediately following step S1;

[0062] S21: Option 1, the A end and B end of the suture cross each other and fold back to form a fastening, forming a movable traction part;

[0063] S22: Option 2, with suture A end and suture B end, one end of the suture body is inserted into the hollow structure of the other end of the suture body, and after inserting for a certain distance, it comes out to form a movable channel T3, i.e., a movable traction part;

[0064] S3: The return process of stitch 2, immediately following step S2;

[0065] S31: Option 1, the A end and B end of the suture are pulled from the other end of the nail body C1 and nail body C2 to one end respectively;

[0066] S32: Option 2, the A end and B end of the suture are pulled from the other end of the nail body C1 and nail body C2 to one end respectively, and are connected to the nail body C1 and nail body C2 in a back-and-forth through-threading manner to form threading segment H1 and threading segment H2 respectively.

[0067] S4: Processing of the movable traction part of the sewing thread 2, immediately following step S3;

[0068] S41: When the suture ends A and B are pulled away from the nail body 1, they pass through the central suture body between the suture ends A and B, and then enter the hollow structure of the suture 2 itself at both ends of the central suture body. After entering for a certain distance, they exit, forming the movable channel T1 and the movable channel T2. As the suture ends A and B continue to move away, the central suture body moves to the inside of one end of the nail body C1 and the nail body C2.

[0069] Understandably, when the above-mentioned anchor is in operation, the anchor body 1 is first placed in the pre-set fixing hole by the full-seam anchor inserter. The cross-section of the full-seam anchor inserter abuts against the anchor body 1. The adjustable coil is tightened by pulling the A end and B end of the suture. The tightening of the adjustable coil drives the anchor body 1 to shrink inward into a ball, thus completing the fixation of the full-seam anchor.

[0070] The stress scenario after full suture anchor implantation is as follows: suture 2 will be continuously subjected to force and relaxation as the patient's joint moves, and this process will repeat.

[0071] It should be understood that when the suture 2 is under stress, the nail body 1 tends to shrink and clump together. When the suture 2 is relaxed, the stress decreases. Under these circumstances, the anchor may loosen and cause excessive displacement. This disclosure uses the friction between the suture 2 and the inner wall of its hollow structure by setting up movable channels T1, T2 and T3 to ensure the stability of the structure under stress changes after the adjustable coil is tightened.
