Description

Technical Field

[0001] The utility model relates to the technical field of all-suture anchors, and particularly relates to an all-suture anchor for promoting tendon-bone healing. Background Art

[0002] Soft tissues such as tendons and ligaments are usually attached to bones through small collagen fibers. These fibers are strong, but tendons and ligaments are flexible. When a soft tissue is torn from a bone and needs to be repaired, a doctor usually uses a suture to repair the separated soft tissue. The suture is fixed through an anchor. Usually, a hole is drilled in the patient's bone, and after the anchor is implanted, the anchor is fixed by deforming the anchor. The suture is generally fixedly connected to the anchor.

[0003] However, in actual operation, since the anchor is fixed to the suture, when the soft tissue is sutured through the suture after the anchor is inserted and fixed, the fixed anchor is likely to become loose due to the pulling of the suture, affecting the fixing stability of the anchor and the tendon-bone healing. Moreover, after the two ends of the suture are sutured, the suture often becomes loose, and the pulling force on the soft tissues on both sides is insufficient, affecting the repair effect. At the same time, the suture is tied to the anchor, and the tying part of the suture and the anchor cannot be accommodated, resulting in a bulge at the sutured part, and it is easy to form a bump at the sutured part during subsequent rehabilitation, affecting the rehabilitation effect.

[0004] Therefore, there is a need for an all-suture anchor for promoting tendon-bone healing with good fixing stability, convenient operation and good suture effect. Content of the Utility Model

[0005] In order to solve the above problems, the utility model proposes an all-suture anchor for promoting tendon-bone healing, which has the characteristics of good fixing effect and strong practicability.

[0006] To achieve the above object, the utility model proposes the following specific solutions:

[0007] An all-suture anchor for promoting tendon-bone healing, comprising an anchor sleeve, the anchor sleeve includes a soft sleeve and an inner insertion cylinder.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] By providing the anchor sleeve, the insertion nail and the suture, during the suture operation, the anchor sleeve is first inserted into the inner side of the hole drilled in the patient's bone, then the suture is passed through the wire groove on the insertion nail, and the two ends of the suture are sutured and fixed to the soft tissues such as the broken tendons on both sides. Then, the insertion nail is inserted into the inner side of the anchor sleeve to achieve fixation. The operation is convenient, the stability of the anchor fixation is not affected during the suture of the suture, and the connection part with the suture can be hidden after the insertion nail is inserted, avoiding the situation of bulging during subsequent healing and improving the healing effect.

[0017] Moreover, the suture penetrates through the insertion nail.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment

[0027] Please refer to Figures 1-5 as shown, the present utility model provides the following technical solutions: A full suture anchor bolt with the function of promoting tendon-bone healing, including an anchor bolt sleeve 1. The anchor bolt sleeve 1 includes a soft sleeve 11 and an inner layer insertion cylinder 12. Refer to the attached Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, specifically, an inner insertion cylinder 12 is fixedly sleeved on the inner side of the soft sleeve 11. The inner insertion cylinder 12 is made of a rigid material. A clamping groove 121 is opened at the upper end of the inner wall of the inner insertion cylinder 12. An insertion groove 122 is opened on the inner bottom surface of the clamping groove 121. A shielding block 123 is fixedly arranged at the top of the inner wall of the clamping groove 121. There are multiple shielding blocks 123, which can limit the clamped clamping plate 23 to prevent the insertion nail 2 from falling off easily. An insertion nail 2 is arranged above the inner insertion cylinder 12. A wire groove 21 is opened at the upper end of the insertion nail 2. A suture 3 is penetrated through the inside of the wire groove 21. The suture 3 can move, which is convenient for suturing the soft tissues at both ends. A clamping plate 23 is fixedly arranged at the top of the insertion nail 2. An insertion plate 24 is fixedly arranged at the edge of the bottom surface of the clamping plate 23. The size of the clamping plate 23 is adapted to the inner size of the clamping groove 121, and the size of the insertion plate 24 is adapted to the inner size of the insertion groove 122. In the stitching process of this solution, first, the anchor nail sleeve 1 is inserted into the inner side of the bone hole for fixation. Then, the suture 3 is penetrated through the insertion nail 2. The soft tissues on both sides are sutured through the suture 3. After stitching, the insertion nail 2 is inserted into the inner side of the anchor nail sleeve 1 to fix the suture 3, thereby preventing the suture 3 from being pulled by the anchor nail sleeve 1 during stitching and improving the stability of the anchor nail fixation. At the same time, if the length of the suture 3 is too long after stitching, resulting in the suture 3 being loose and the pulling force on the soft tissues at both ends being insufficient, the suture 3 can be wound by rotating the insertion nail 2 to tighten the suture 3, and then inserted into the inner side of the anchor nail sleeve 1 again to increase the pulling force of the suture 3 on the soft tissues and promote healing.

[0028] Referring to Figure 2 With Figure 5 As shown, specifically, a first friction ring 111 is fixedly arranged at the upper end of the outer wall of the soft sleeve 11 to improve the insertion stability of the anchor nail sleeve 1 after insertion. A stabilizing sleeve 13 is fixedly arranged at the bottom of the inner insertion cylinder 12. The stabilizing sleeve 13 includes an elastic ring 131. The top of the elastic ring 131 is fixed to the bottom surface of the inner insertion cylinder 12, and the bottom of the elastic ring 131 is fixed to the inner bottom surface of the soft sleeve 11. A first extrusion ring 132 is fixedly arranged on the inner wall of the elastic ring 131, and a second extrusion ring 133 is fixedly arranged on the outer wall of the elastic ring 131. After the insertion nail 2 is inserted, the first extrusion ring 132 and the second extrusion ring 133 can be pushed outward, thereby pushing up the outer soft sleeve 11 to generate deformation and improving the insertion stability. A second friction ring 25 is fixedly arranged on the outer wall of the lower end of the insertion nail 2. The first friction ring 111 and the second friction ring 25 are made of flexible materials. The first extrusion ring 132 and the second extrusion ring 133 are made of elastic materials. This solution improves the insertion stability of the anchor nail sleeve 1 through the outer friction ring and the inner extrusion ring, avoiding the situation that loosening affects healing.

[0029] Referring to Figure 2 With Figure 3As shown, specifically, a stepped clamping plate 22 is fixedly arranged on the inner top surface of the wire trough 21, and the sewing thread 3 is clamped inside the stepped clamping plate 22; this solution can achieve clamping and limiting of sewing threads 3 of different sizes through clamping plates with different spacings, facilitating the selection of sewing threads of appropriate thickness according to the suture situation, and has strong practicability.

[0030] The working principle and usage process of the present utility model: When performing a suture operation on a patient with a soft tissue fracture, a hole is drilled in the patient's bone, the anchor sleeve 1 is inserted into the inner side of the hole, and friction limiting is carried out through the first friction ring 111. Subsequently, the sewing thread 3 is passed through the plugging nail 2, and the two sides of the soft tissue are sutured through the two ends of the sewing thread 3. Then, the medical staff can rotate the plugging nail 2 according to the tightness state of the sewing thread 3 to achieve winding and tensioning of the sewing thread 3. Subsequently, the plugging nail 2 is inserted into the inner side of the anchor sleeve 1 to achieve plugging and limiting of the plugging nail 2, thereby realizing the fixation of the sewing thread 3. After the plugging nail 2 is inserted, it pushes the first extrusion ring 132 and the second extrusion ring 133, causing the extrusion ring to lift the soft sleeve 11 and deform it, further improving the fixing stability of the anchor sleeve 1. The operation is convenient and promotes healing.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
