Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a method for tying a connecting wire loop in a wire anchor and a wire anchor. Background Art

[0002] As the number of people who exercise increases, sports injuries are becoming more and more common. Currently, common sports injuries mostly involve tendons or ligaments. Tendons generally refer to the connection between muscles and bones, and their main function is to control bone movement. Ligaments often refer to the connection between bones, and their main function is to fix bones. The repair of tendon and ligament injuries is to use repair implants to re-fix the damaged tissue. When repairing sports injuries, the most commonly used repair implant in clinical practice is the wire anchor. The wire anchor is implanted into the tendon or ligament bone attachment point, and then the suture on the wire anchor is used to suture the tendon or ligament, and finally the damaged tendon or ligament is re-fixed to achieve functional recovery.

[0003] The wire anchor consists of the anchor itself, a connecting loop made of long braided wire, and a suture. The connecting loop connects the anchor to the suture, which is then sewn to the damaged tendon to complete the repair. Therefore, the wire anchor must first meet mechanical strength requirements and then meet microbiological indicators.

[0004] In the prior art, due to the biomechanical strength requirements, the wire anchor body needs to be coated with glue at the connection position between the head end of the anchor body and the connecting wire ring to ensure mechanical strength. However, this method of coating glue may cause rejection reactions in some patients, resulting in the risk of biocompatibility of the wire anchor body. Summary of the Invention

[0005] In order to improve the patient's rejection reaction as much as possible while meeting the biomechanical strength requirements of the wire anchor and reduce the risk of biocompatibility of the wire anchor, the present application provides a knotting method for the connecting wire loop in the wire anchor.

[0006] The present application provides a method for tying a connecting wire loop in a wire anchor using the following technical solution:

[0007] A method for tying a connecting wire loop in a wire anchor comprises the following steps:

[0008] Step 1: Use a long line made of ultra-high molecular weight polyethylene material, with braided end A and braided end B at both ends. Braided end A is wrapped around itself to form a first coil, and braided end B passes through the first coil to form a second coil.

[0009] Step 2: Tighten the braided end A so that the first coil is tightened to form a first knot, and the second coil forms a first loop. The braided end B can slide in the first knot.

[0010] Step 3: The node in the first thread loop opposite to the first thread knot is inserted into the threading hole from the head of the anchor body and then passed out from the tail of the anchor body. One end of the suture passes through the first thread loop at the tail of the anchor body.

[0011] Step 4: The braided end B is wrapped around the loop segment of the first loop close to the braided end B and then wrapped around itself to form a third coil. The loop segment of the first loop close to the braided end B is located inside the third coil.

[0012] Step 5: Tighten the braided end B so that the third loop is tightened to form a second knot, and an adjustment loop is formed between the first knot and the second knot;

[0013] Step 6: Cut off the extra long line segments at the end of the first and second line knots;

[0014] Step 7: Pull the suture in a direction away from the first thread loop until the first thread knot and the second thread knot are located in the thread retaining hole and press against the bottom of the thread retaining hole.

[0015] By adopting the above technical solution, when suturing a tendon or ligament, the suture is tightened in the direction close to the bottom of the anchor body, so that the first knot and the second knot move in a direction close to each other, the adjustment loop becomes smaller, and the first loop becomes larger. The first knot and the second knot are pressed against each other so that the first knot and the second knot can be suspended in the clamping hole at the same time, so that the first knot and the second knot will not be separated from the anchor body due to external force, thereby meeting the requirements of biomechanics;

[0016] Compared to glue-based fixation, knotting the wire loops eliminates biocompatibility risks. This significantly reduces the likelihood of product rejection in patients, facilitating postoperative recovery. Furthermore, the suture can be suspended from the anchor using only the knotted wire loop, eliminating the need for additional glue or other raw materials, reducing manufacturing costs and eliminating the need to apply glue to the anchor tip and then heat-press, thus simplifying production.

[0017] Preferably, the braided end A presses the long wire segment close to the braided end A to form a first braided coil, and then the braided end A goes around the long wire segment close to the braided end A and passes through the first braided coil to form a first coil.

[0018] By adopting the above technical solution, after the braided end B passes through the first coil, the first coil is tightened and the braided end B can slide inside the first coil to facilitate adjustment of the size of the first wire loop, and the first knot is not easy to loosen.

[0019] Preferably, the braided end B passes through the first wire loop and presses the long wire segment close to the braided end B to form a second braided coil, and then the braided end B goes around the long wire segment close to the braided end B and passes through the second braided coil to form a third coil.

[0020] By adopting the above technical solution, after the third coil woven in this way is tightened into the second knot, the second knot is not easy to loosen, and at the same time, the size of the adjustment loop located between the first knot and the second knot can be adjusted, thereby adjusting the distance between the first knot and the second knot, so that after the knot is pulled by external force, the distance between the first knot and the second knot can become smaller and smaller, and the knot becomes tighter and tighter.

[0021] Preferably, the ring segments of the first loop located on both sides of the first knot are respectively the first ring segment and the second ring segment, the first ring segment is connected to the braiding end A, the second ring segment is connected to the braiding end B and slides in or out of the first knot with the braiding end B, and the second knot is located on the first ring segment.

[0022] By adopting the above technical solution, only the second knot is located on the first ring segment, and the second knot can slide on the first ring segment, thereby achieving the effect of adjusting the size of the adjustment loop.

[0023] Preferably, after one end of the suture passes through the first wire loop, the braided end B is pulled in a direction away from the anchor body, and the first wire loop is adjusted to a desired length.

[0024] By adopting the above technical solution, the length of the first thread loop should not be too long, and the best effect is achieved when the first thread loop is located entirely inside the anchor body. In this way, when the suture is suturing the tendon or ligament, the first thread loop will not contact the tendon or ligament, thereby avoiding the phenomenon of secondary damage to the patient's body caused by the shaking of the first thread loop during suture.

[0025] Preferably, the first wire loop is passed through the threading hole by a thread passing tool, one end of the thread passing tool passes into the anchor body from the tail of the anchor body and out from the head of the anchor body, one end of the thread passing tool passes through the head of the anchor body and is connected to the first wire loop and the first wire loop is pulled in a direction close to the tail of the anchor body until the first wire loop passes through the threading hole and is connected to the suture.

[0026] By adopting the above technical solution, the shape of the first wire loop is easily deformed by the action of external force, and the length of the threading through hole is long, and the first wire loop is difficult to pass through the threading through hole. Therefore, in order to facilitate the first wire loop to pass through the threading through hole, a wire passing tool is used to extend from the tail of the anchor body into the threading through hole and extend from the head of the anchor body to facilitate the connection between the wire passing tool and the first wire knot. The first wire loop is pulled in the direction close to the tail of the anchor body by the wire passing tool to guide the moving direction of the first wire loop so that the first wire loop can pass through the threading through hole, thereby reducing the difficulty of connecting the wire knot and the suture.

[0027] Preferably, the wire passing tool includes a long wire passing rope that can be bent and deformed, and the two ends of the wire passing rope are respectively a rope end A and a rope end B. The rope end A passes through the tail of the anchor body through the threading hole and passes through the head of the anchor body, and then the rope end A passes through the first wire loop, and then the rope end A passes through the head of the anchor body and passes through the tail of the anchor body. The rope end A and the rope end B are located on the same side of the anchor body, and then the rope end A and the rope end B are pulled simultaneously in a direction away from the anchor body until the first wire loop passes through the threading hole.

[0028] By adopting this technical solution, the flexible and easily deformable long string facilitates its passage through the threading hole and the first wire loop, and its bending back through the threading hole, making it easier to pull the first wire loop. Furthermore, as the long string moves through the threading hole, the flexible string reduces the risk of scratching the hole wall, thereby preserving the integrity of the anchor body and the knot as much as possible.

[0029] Preferably, check whether the knotting method of the connecting wire loop is correct: pull the first knot and the second knot in directions away from each other, the first knot and the second knot can slide in directions away from each other, and the adjustment wire loop becomes larger, then the knotting method of the connecting wire loop is correct.

[0030] By adopting the above technical solution, it is easy to make mistakes when weaving the knot. If the knot is wrongly weaved, it will affect the strength of the knot and increase the risk of the knot detaching from the anchor. In order to be able to promptly detect whether the knot is tied correctly, after the knot is tied, the first knot and the second knot are pulled in directions away from each other. If the distance between the first knot and the second knot increases, the knotting method of the connecting wire loop is correct.

[0031] Preferably, it includes a connecting wire loop woven by a knotting method of a connecting wire loop in a wire anchor, and also includes an anchor body connected to the connecting wire loop, wherein the anchor body is made of PEEK or HA-PEEK material.

[0032] Through the above technical solution, the anchor body made of PEEK or HA-PEEK material can improve the biocompatibility of the anchor body while ensuring the structural strength of the anchor body itself.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. When suturing a tendon or ligament, the suture is tightened along the first loop toward the bottom of the anchor body, causing the first and second knots to move toward each other. As the adjustment loop becomes smaller, the first loop becomes larger, causing the fixed knot to become tighter under the action of external force. The overall size of the first and second knots can be suspended in the thread-locking hole, preventing the first and second knots from detaching from the anchor body due to external forces, thus meeting the requirements of biomechanics.

[0035] 2. After the knot is tightened, the braided end B can slide inside the first knot, so as to adjust the size of the first loop and prevent the first knot from falling off.

[0036] 3. After the third coil is tightened into the second knot, the second knot is not easy to loosen and can adjust the distance between the first knot and the second knot at the same time, so that when the knot is pulled by external force, the distance between the first knot and the second knot can become smaller and smaller, and the fixed knot becomes tighter and tighter.

[0046] The following is combined with Figure 1-8 This application is described in further detail.

[0047] Reference Figure 1 and Figure 2 The wire anchor includes an anchor body 1, a connecting wire ring 2 and a suture 3.

[0048] Among them, a threading through hole 11 is arranged along the axis direction of the anchor body 1, and the threading through hole 11 connects the head of the anchor body 1 and the tail of the anchor body 1. A wire clamping hole 12 is opened at the head of the anchor body 1 and is coaxially connected to the threading through hole 11. The diameter of the wire clamping hole 12 is larger than the threading through hole 11.

[0049] Furthermore, the connecting wire loop 2 includes a securing knot 21 and a connecting loop 22, which are braided from a single long wire 4. The securing knot 21 is positioned within the wire retaining hole 12 and abuts against the bottom of the hole, minimizing the risk of the securing knot 21 entering the threading hole 11. The connecting loop 22 is positioned within the threading hole 11. The suture 3 passes through the rear end of the anchor body 1, enters the threading hole 11, and connects to the connecting loop 22.

[0050] When the suture 3 is suturing the tendon or ligament, the suture 3 will tighten the connecting wire ring 22 in the direction close to the tail end of the anchor body 1, thereby driving the fixing knot 21 to press against the bottom of the wire clamping hole 12. The position of the fixing knot 21 is limited by the wire clamping hole 12 to further reduce the probability of the fixing knot 21 detaching from the anchor body 1, thereby enhancing the connection strength between the anchor body 1 and the connecting wire ring 2.

[0051] The present application discloses a method for tying a connecting wire loop in a wire anchor. The method specifically includes the following steps:

[0052] Step 1;

[0053] Reference Figure 3 The two ends of the long wire 4 are respectively a braided end A41 and a braided end B42. The braided end A41 is wrapped around itself to form a first coil 43, and the braided end B42 passes through the first coil 43 to form a second coil 44.

[0054] Step 2;

[0055] Reference Figure 4 , tightening the braided end A41 so that the first coil 43 is tightened to form a first knot 5, so that the second coil 44 forms a first loop 6, and the braided end B42 can slide in the first knot 5;

[0056] like Figure 3 As shown, the braiding method of the first coil 43 is as follows: the braiding end A41 presses the long wire 4 segment near the braiding end A41 to form the first braiding coil, and then the braiding end A41 passes around the long wire 4 segment near the braiding end A41 and passes through the first braiding coil to form the first coil 43;

[0057] After the first coil 43 woven in this weaving method forms the first knot 5, the weaving end B42 will slide in the first knot 5 under the action of external force, thereby adjusting the size of the first wire loop 6 and the first knot 5 is not easy to loosen, thereby improving the firmness of the first knot 5.

[0058] Step 3;

[0059] Reference Figure 5 and Figure 6 The node of the first thread loop 6 opposite to the first thread knot 5 extends from the head of the anchor body 1 into the threading hole 11 and then passes through the tail of the anchor body 1, so that the first thread loop 6 becomes a wiring loop 22, and one end of the suture 3 passes through the first thread loop 6 located at the tail of the anchor body 1;

[0060] The shape of the first thread loop 6 is easily deformed by external forces, and the threading hole 11 is long, making it difficult for the first thread loop 6 to pass through the threading hole 11. In order to facilitate the connection between the first thread loop 6 and the suture 3, a thread passing tool is required to facilitate the first thread loop 6 passing through the threading hole 11. The thread passing tool can be a long thread passing rope 9 that can be bent and deformed;

[0061] The two ends of the long wire rope 9 are respectively a rope end A91 and a rope end B92. The rope end A91 passes through the threading hole 11 from the tail of the anchor body 1 and passes through the head of the anchor body 1. Then the rope end A91 passes through the first wire loop 6. After that, the rope end A91 passes through the head of the anchor body 1 and passes through the tail of the anchor body 1. The rope end A91 and the rope end B92 are located at the tail of the anchor body 1. Then, the rope end A91 and the rope end B92 are pulled simultaneously in a direction away from the anchor body 1 until the first wire loop 6 passes through the threading hole 11.

[0062] One end of the suture 3 passes through the first loop 6 at the rear end of the anchor body 1, thereby connecting the first loop 6 and the suture 3. The long thread rope 9 is flexible and can guide the first loop 6 through the threading hole 11 while reducing the risk of scratching the hole wall 11, thereby maintaining the integrity of the anchor body 1 as much as possible.

[0063] Step 4;

[0064] Reference Figure 2 and Figure 6 After the suture 3 and the first loop 6 are connected, part of the first loop 6 is still located at the tail end of the anchor body 1. When the suture 3 is used to sew the tendon or ligament, the first loop 6 will shake and come into contact with the tendon or ligament, increasing the chance of secondary damage to the patient's body. Therefore, the length of the first loop 6 should not be too long. For best results, the first loop 6 should be located entirely inside the anchor body 1.

[0065] Therefore, after one end of the suture 3 passes through the first wire loop 6, the braided end B42 is pulled in a direction away from the head of the anchor body 1, and the first wire loop 6 is gradually retracted into the anchor body 1 until the first wire loop 6 reaches the required length.

[0066] After adjusting the size of the first thread loop 6, the size of the first thread loop 6 needs to be limited. At the same time, the braided end B42 is still able to slide freely in the first thread knot 5. Under the action of external force, the braided end B42 is easy to break away from the first thread knot 5, causing the thread loop 2 and the suture 3 to separate. Therefore, the braided end B42 needs to be limited.

[0067] Step 5;

[0068] Reference Figure 7 The braided end B42 passes through the first wire loop 6 and presses the long wire 4 segment near the braided end B42 to form a second braided coil. Then, the braided end B42 passes around the long wire 4 segment near the braided end B42 and passes through the second braided coil to form a third coil 45. The loop segment of the first wire loop 6 near the braided end B42 is located inside the third coil 45.

[0069] The ring segments of the first wire loop 6 located on both sides of the first wire knot 5 are respectively the first ring segment 61 and the second ring segment 62. The first ring segment 61 is connected to the weaving end A41, and the second ring segment 62 is connected to the weaving end B42 and slides in or out of the first wire knot 5 with the weaving end B42. The second wire knot 7 is located on the first ring segment 61.

[0070] Step 6;

[0071] Reference Figure 2 and Figure 8 , tighten the braided end B42 so that the third coil 45 is tightened to form a second knot 7, and an adjustment loop 8 is formed between the first knot 5 and the second knot 7;

[0072] After the third loop 45 is tightened to form the second knot 7, the second knot 7 is not easily loosened. At the same time, the size of the adjustment loop 8 between the first knot 5 and the second knot 7 can be adjusted, thereby adjusting the distance between the first knot 5 and the second knot 7. The first knot 5 and the second knot 7 together form a fixing knot 21. When pulled by an external force, the distance between the first knot 5 and the second knot 7 becomes smaller and smaller, resulting in an increasingly tight fixing knot 21.

[0073] Step 7;

[0074] The excess long line 4 segments at the tail ends of the first knot 5 and the second knot 7 are cut off to reduce the long line 4 located in the human body, thereby reducing the probability of the long line 4 contacting the tendon or ligament, which is convenient for the patient's recovery in the future.

[0075] Step 8;

[0076] The suture 3 is pulled in a direction away from the first thread loop 6, and the first thread knot 5 and the second thread knot 7 are located in the thread retaining hole 12 and pressed against the bottom of the thread retaining hole 12;

[0077] The connecting wire loop 2 is prone to weaving errors during weaving. If the connecting wire loop 2 is weaved incorrectly, the strength of the connecting wire loop 2 will be affected and the risk of the connecting wire loop 2 being separated from the anchor body 1 will be increased. Therefore, a method is needed to determine whether the knot of the connecting wire loop 2 is correctly tied.

[0078] If the connecting wire loop 2 is tied correctly, by pulling the first wire knot 5 and the second wire knot 7 away from each other, the adjusting wire loop 8 can become larger and the first wire loop 6 can become smaller.

[0079] When suturing tendons or ligaments, the suture 3 tightens the first thread loop 6 in the direction close to the bottom of the anchor body 1, so that the first thread knot 5 and the second thread knot 7 move in the direction close to each other, the adjustment thread loop 8 becomes smaller, and the first thread loop 6 becomes larger, so that the connecting thread loop 2 becomes tighter and tighter under the action of external force, and the size of the thread knot can be suspended in the thread clamping hole 12, so that the thread knot will not be separated from the anchor body 1 due to the action of external force.

[0080] To ensure that the long thread 4 used to braid the suture 3 and the connecting wire loop 2 can meet mechanical requirements, the long thread 4 and the suture 3 are both made of ultra-high molecular weight polyethylene. The anchor body 1 is made of PEEK or HA-PEEK material, thereby improving the biocompatibility of the wire anchor.

[0081] The braided connecting wire loop 2 of the present application meets the requirements of biomechanics in terms of the pulling strength of bearing external forces. Compared with the traditional wire loop connection method of knotting and gluing, the present application has the following advantages:

[0082] First, the present application adopts a wire loop knotting method to connect with the anchor body 1, thereby avoiding the risk of biocompatibility, greatly reducing the possibility of the patient's body rejecting the product, and facilitating the patient's postoperative recovery;

[0083] Second, the existing knots have low horizontal tensile strength and are easily deformed, which can lead to them being pulled into the threading hole, causing the anchor to fail. Therefore, glue is needed to secure the knot. However, the connecting wire loop 2 woven using the knotting method of the present application can suspend the suture 3 on the anchor body 1. During the suture pulling process, the overall knot formed by the first knot 5 and the second knot 7 has higher horizontal tensile strength and is less likely to deform horizontally. No additional glue or other raw materials are required, reducing manufacturing costs.

[0084] Third, applying glue to the head end of the anchor requires hot pressing of the glue to dry the glue. This application directly omits the hot pressing step, thereby reducing the difficulty of production.

[0085] The implementation principle of the knotting method of the connecting wire loop in the wire anchor according to the embodiment of the present application is as follows: when suturing the tendon or ligament, the suture 3 tightens the first wire loop 6 in the direction close to the bottom of the anchor body 1, so that the first knot 5 and the second knot 7 move in the direction close to each other, the adjustment wire loop 8 becomes smaller, and the first wire loop 6 becomes larger, so that the connecting wire loop 2 becomes tighter and tighter under the action of external force, and the size of the connecting wire loop 2 can be suspended in the wire clamping hole 12, so that the connecting wire loop 2 will not be separated from the anchor body 1 due to the action of external force, thereby meeting the biomechanical requirements and ultimately meeting the biomechanical strength requirements of the wire anchor, thereby improving the patient's rejection reaction as much as possible to reduce the risk of biocompatibility of the wire anchor.

[0086] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
