Description

Technical Field

[0001] This application relates to the field of ligament repair technology, and in particular to a ligament rupture repair implant. Background Technology

[0002] Ligaments are primarily composed of collagen fibers and elastic fibers. Collagen fibers give ligaments strength and rigidity, while elastic fibers endow them with the ability to stretch under load. Strong ligaments enhance bone stability, steadily hold internal organs in their proper positions, and limit their range of motion to prevent injury. Excessive exercise and severe sprains can lead to ligament tears or ruptures, requiring surgical treatment to repair the torn ligaments.

[0003] Currently, the conventional treatment for ligament tears is surgical reconstruction, which involves removing the torn ligament and replacing it with the patient's own tendon or another donor tendon. However, this treatment method has drawbacks such as high surgical complexity, significant surgical trauma, and long recovery time. Therefore, ligament repair implants, a treatment method that does not require tendon cultivation or transfer, are increasingly used in the treatment of ligament tears.

[0004] Medical staff place the implant at the site of the ligament tear and suture it in place. The implant then acts as a bridge between the torn ligament and the wound, aiding in healing. However, suturing the implant to the ligament requires repeated threading of the sutures. Due to the limited space, it is difficult for medical staff to precisely control each suturing action, resulting in poor suturing at the ligament tear and affecting subsequent ligament repair. Utility Model Content

[0005] To improve the suturing effect of the implant at the ligament tear site, this application provides a ligament rupture repair implant.

[0006] This application provides a ligament rupture repair implant with the following technical solution:

[0007] A ligament rupture repair implant includes an implant body and a mesh body. The implant body is used to insert between the two ends of a torn ligament, and the mesh body is provided at each end of the implant body and is circumferentially wrapped around the implant body.

[0008] By adopting the above technical solution, medical staff place the implant between the two ends of the patient's torn ligament, and then suture the mesh at both ends of the implant to the two ends of the ligament tear. This positions the implant at the ligament tear. During the suturing process, the pores on the mesh allow the suture to pass through, making it easy for the suture to be sewn onto the mesh circumferentially wrapped around the implant. This facilitates the suturing operation for medical staff. Furthermore, during the suturing process, the mesh can deform as the suture is sewn, reducing the possibility of ligament tearing during suturing and improving the suturing effect of the implant at the ligament tear.

[0009] Optionally, the mesh is embedded in the implant, and a mesh cover is provided at one end of the mesh located in the implant.

[0010] By adopting the above technical solution, the stability of the mesh in the implant is effectively improved by embedding the mesh body in the implant and embedding the mesh cover in the implant.

[0011] Optionally, the implant has multiple holes that extend from one end of the implant to the other.

[0012] By adopting the above technical solution, multiple pores provide channels for the growth of ligament cells, thereby improving the healing speed at both ends of the ligament cells.

[0013] Optionally, the mesh cover is provided with a connecting wire that passes through the hole and is connected to the mesh cover at the other end of the implant.

[0014] By adopting the above technical solution, the connecting wire connects the mesh caps at both ends of the implant, thereby connecting the mesh at both ends of the implant and further improving the stability of the mesh on the implant.

[0015] Optionally, the implant, mesh, mesh cover, and connecting wires are all made of biocompatible materials.

[0016] By adopting the above technical solutions, and by using implants, meshes, mesh covers, and connecting wires made of biocompatible materials, the biocompatibility of the implants, meshes, mesh covers, and connecting wires can be improved.

[0017] Optionally, the implant, mesh, mesh cover, and connecting wires are all made of biodegradable materials.

[0018] By adopting the above technical solution, and by using biodegradable materials for the implant, mesh, mesh cover, and connecting wires, the implant, mesh, mesh cover, and connecting wires can be gradually absorbed by the patient's body, avoiding the pain and surgical risks caused by a second surgery to remove the implant, mesh, mesh cover, and connecting wires.

[0019] Optionally, the implant is cylindrical.

[0020] By adopting the above technical solution and using a cylindrical implant, medical staff can place the implant between the two ends of the torn ligament without adjusting the insertion angle, thus improving the convenience of implant placement in the patient.

[0021] Optionally, all corners of the implant are chamfered.

[0022] By adopting the above technical solution, the implant with chamfered edges and corners reduces the possibility of causing harm to the patient when the implant is placed in the patient's body.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the suturing process, the pores on the mesh allow the suture to pass through, making it easy to suture the suture to the mesh that is circumferentially wrapped around the implant. This facilitates the suturing operation by medical staff. Furthermore, during the suturing process, the mesh can deform as the suture is stitched, reducing the possibility of ligament tearing during suturing and improving the suturing effect of the implant at the ligament tear site.

[0025] 2. Multiple pores provide channels for the growth of ligament cells, improving the healing speed at both ends of the ligament cells;

[0026] 3. Connecting wires connect the mesh caps at both ends of the implant, thereby connecting the mesh at both ends of the implant and further improving the stability of the mesh on the implant. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses an implant for repairing ligament rupture.

[0032] Reference Figure 1The ligament rupture repair implant includes an implant body 1 and a mesh body 2. The implant body 1 is inserted between the two ends of the torn ligament. The implant body 1 is made of a biocompatible material and is biodegradable. In this embodiment, the implant body 1 is made of decellularized bovine type I collagen. By using a biocompatible and biodegradable material for the implant body 1, the biocompatibility between the patient and the implant body 1 is improved after implantation between the two ends of the torn ligament, thus improving patient comfort. Furthermore, the implant body 1 is gradually absorbed by the patient as the ligament repairs, avoiding the pain and surgical risks caused by a second surgery to remove the implant body 1.

[0033] Reference Figure 1 The implant 1 is cylindrical in shape, and all its edges and corners are chamfered. The use of a cylindrical implant 1 with chamfered edges and corners allows medical personnel to easily insert the implant 1 between the two ends of the torn ligament without adjusting the insertion angle. This improves the convenience of implant placement and reduces the possibility of injury to the patient from contact with the edges and corners of the implant during insertion.

[0034] Reference Figure 1 , Figure 2 The mesh body 2 is embedded at both ends of the implant 1. The mesh body 2 is circumferentially wrapped around the implant 1, and a mesh cover 3 is installed at one end of the mesh body 2 embedded in the implant 1. The mesh cover 3 closes the opening formed by the end of the mesh body 2 located in the implant 1. Both the mesh body 2 and the mesh cover 3 are mesh structures.

[0035] By embedding the mesh 2 within the implant 1 and embedding the mesh cover 3 within the implant 1, the resistance required for the mesh 2 to detach from the implant 1 is increased, thereby effectively improving the stability of the mesh 2 on the implant 1.

[0036] Reference Figure 1 , Figure 2 Multiple holes 11 are provided on the implant 1 along the line connecting the two ends of the ligament tear. The holes 11 pass through one end of the implant 1 to the other end of the implant 1. Multiple connecting wires 4 are installed on one of the mesh covers 3. The multiple connecting wires 4 are respectively inserted into the multiple holes 11 and connected to another mesh cover 3.

[0037] Multiple holes 11 provide channels for ligament growth and healing, allowing ligament cells at both ends of the ligament tear to grow and heal through the holes 11 before the implant 1 and mesh 2 degrade, thus achieving healing at both ends of the ligament tear and improving the healing speed of the ligament cells at both ends; while the connecting line 4 passes through the holes 11 to connect the two mesh covers 3, thereby allowing the two meshes 2 to hold each other together, reducing the possibility of meshes 2 moving away from the other mesh 2, and further improving the stability of meshes 2 on the implant 1.

[0038] Reference Figure 1 , Figure 2 The mesh body 2, mesh cover 3, and connecting wire 4 are all made of biocompatible materials, and all of them are biodegradable. In this embodiment, the mesh body 2, mesh cover 3, and connecting wire 4 are all made of polycaprolactone, which reduces the possibility of rejection reaction of the mesh body 2, mesh cover 3, and connecting wire 4 in the patient's body, improves the patient's biocompatibility with the mesh body 2, mesh cover 3, and connecting wire 4, and the mesh body 2, mesh cover 3, and connecting wire 4 can be gradually absorbed in the patient's body, avoiding the pain and surgical risks caused by a second surgery to remove the mesh body 2, mesh cover 3, and connecting wire 4.

[0039] The implementation principle of a ligament rupture repair implant according to an embodiment of this application is as follows: After cleaning the torn ligament of the patient, the medical staff places the implant 1 between the two ends of the ligament tear, so that the mesh 2 at both ends of the implant 1 covers the two ends of the ligament tear respectively. Then, the mesh 2 and the ligament tear are sutured together, thereby positioning the implant 1 between the two ends of the ligament tear as a bridge for ligament healing. During the suturing process, the pores on the mesh 2 make it easy for the medical staff to thread the suture, so that the suture can easily suture the mesh 2 circumferentially to the ligament. During the suturing process, the mesh 2 can deform as the suture is sewn, reducing the possibility of ligament tearing during suturing. Afterwards, the ligaments at both ends of the ligament tear can grow and heal through the bridge of the implant 1 and the multiple holes 11 on the implant 1, which together improves the suturing effect of the implant at the ligament tear.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
