Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and particularly to a fully sutured anchor with a imaging function. Background Art
[0002] In recent years, with the increasingly wide application of hard material anchor technology, it is known that hard material anchors have many defects: after the titanium alloy metal anchor is implanted, it is easy to cause inflammation due to rejection reaction, resulting in osteolysis at the implantation site, causing the anchor to loosen and shift, resulting in fixation failure.
[0003] To solve the problems existing in hard material anchors, fully sutured anchor products have emerged. A fully sutured anchor is a suture - attached anchor, mainly including an anchor part and a suture part integrated on the anchor part, and can be applied to the repair of tendon - to - bone attachment ruptures throughout the body, that is, used for any part where soft tissue needs to be re - connected to bone.
[0004] Regarding the above - mentioned related technologies, the inventor believes that the existing fully sutured anchors have the problem of insufficient knotting, are prone to failure, and have the defect of poor anchoring effect. Summary of the Utility Model
[0005] In order to improve the anchoring effect, the present application provides a fully sutured anchor with a imaging function.
[0006] The fully sutured anchor with a imaging function provided by the present application adopts the following technical solution:
[0007] A fully sutured anchor with a imaging function includes an anchor body and a imaging suture. A cavity is opened inward at one end surface of the anchor body. At both ends of one side wall of the anchor body, a first thread - passing hole and a second thread - passing hole are respectively penetrated. Both the first thread - passing hole and the second thread - passing hole are communicated with the cavity. At both sides of the bottom wall of the anchor body, a third thread - passing hole and a fourth thread - passing hole are respectively penetrated. Both the third thread - passing hole and the fourth thread - passing hole are communicated with the cavity. At the side wall of the anchor body facing away from the first thread - passing hole, a fifth thread - passing hole and a sixth thread - passing hole are penetrated. Both the first thread - passing hole and the second thread - passing hole are communicated with the cavity. The fifth thread - passing hole and the sixth thread - passing hole are respectively opened at both ends of the anchor body. The imaging suture sequentially passes through the first thread - passing hole, the second thread - passing hole, the third thread - passing hole, the fourth thread - passing hole, the fifth thread - passing hole and the sixth thread - passing hole.
[0008] By adopting the above - mentioned technical solution, after the threaded anchor body is inserted into a pre - fabricated bone tunnel, then medical staff pull both ends of the imaging suture, so that the imaging suture starts to contract. The contraction of the imaging suture changes the shape of the anchor body. Due to the frictional force between the anchor body and the inner wall of the bone tunnel, the anchor body will gradually contract into a mass, increasing the thickness of the anchor body inside the bone tunnel. Thus, the anchor body is firmly fixed in the bone tunnel, thereby improving the anchoring effect.
[0009] Optionally, a supporting ball is placed in the cavity of the anchor body.
[0010] By adopting the above technical solution, since the anchor body may collapse due to long-term use, the anchor body may fall off the prefabricated bone channel. The support ball will support the inner wall of the anchor body, making it difficult for the anchor body to collapse, thereby further improving the anchoring effect.
[0011] Optionally, the side walls on both sides of the support ball are provided with line passing openings extending inwardly in an inclined direction, and the developing line passes through the line passing openings.
[0012] By adopting the above technical solution, the developing line is shrunk and tightened so that the supporting ball is not easy to move, thereby achieving the effect of limiting the position of the supporting ball.
[0013] Optionally, a limiting plate is annularly fixed on the end surface of the anchor body at one end of the cavity away from the supporting ball, and the limiting plate is in a circular ring shape.
[0014] By adopting the above technical solution, the limiting piece makes it difficult for the supporting ball to escape from the cavity, thereby further achieving the effect of limiting the supporting ball.
[0015] Optionally, the side wall of the anchor body between the first threading hole and the second threading hole is provided with a first groove along its length direction, and the inner wall of the anchor body at the first groove is fixed with a plurality of first coils, and the developing line passes through all the first coils.
[0016] By adopting the above technical solution, the first coil guides the developing line, thereby achieving the effect of limiting the developing line by the first coil.
[0017] Optionally, the anchor body has a second groove on its bottom wall between the third threading hole and the fourth threading hole along its width direction, and the anchor body has a plurality of second coils fixed on the inner wall of the second groove, and the developing line passes through all the second coils.
[0018] By adopting the above technical solution, the second coil guides the developing line, thereby achieving the effect of the second coil limiting the developing line.
[0019] Optionally, the anchor body has a third groove on its side wall between the fifth threading hole and the sixth threading hole along its length direction, and the anchor body has a plurality of third loops fixed on its inner wall at the third groove, and the developing line passes through all the third loops.
[0020] By adopting the above technical solution, the third coil guides the developing line, thereby achieving the effect of the third coil limiting the developing line.
[0021] Optionally, the third threading hole and the fourth threading hole are opened in an inclined direction, and the tops of the third threading hole and the fourth threading hole are close to each other.
[0022] By adopting the above technical solution, the third threading hole and the fourth threading hole are obliquely opened so that the developing line can wrap more of the bottom wall of the anchor body, thereby achieving the effect of being able to fully shrink the anchor body.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The medical staff pulls the developing line to shrink the developing line, and the contraction of the developing line causes the anchor body to gradually shrink into a ball, and the thickness of the anchor body inside the bone canal increases, thereby increasing the friction between the anchor body and the inner wall of the bone canal, so that the anchor body is firmly fixed in the bone canal, thereby improving the anchoring effect;
[0025] 2. The support ball will support the inner wall of the anchor body, making it difficult for the anchor body to collapse, further improving the anchoring effect;
[0026] 3. The limiting piece makes it difficult for the supporting ball to escape from the cavity, further achieving the effect of limiting the supporting ball. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The following is combined with Figures 1-4 This application is described in further detail.
[0033] The embodiment of the present application discloses a full suture anchor with a developing function.
[0034] refer to Figure 1 A full suture anchor with a developing function comprises an anchor body 1 and a developing line 2. The anchor body 1 is in the shape of a long strip, and a cavity 11 is provided in the anchor body 1. The cavity 11 passes through the end face of one end of the anchor body 1. The end face of the anchor body 1 at the cavity 11 is annularly fixedly connected with a limiting plate 4. The limiting plate 4 is in the shape of a circular ring. The developing line 2 is a suture made of a material that is not transparent to X-rays. The developing line 2 passes through the side wall and the bottom wall of the anchor body 1, and both ends of the developing line 2 pass through the circular hole in the center of the limiting plate 4 and extend to the outside.
[0035] The medical staff inserts the anchor body 1 into the prefabricated bone channel using an inserter, and then pulls out the free end of the developing line 2 remaining on the outside of the anchor body 1, thereby gradually shrinking and folding the anchor body 1 into a ball.
[0036] refer to Figure 1 A first threading hole 12 is formed through one end of the side wall of the anchor body 1 close to the limiting plate 4, and the first threading hole 12 is connected to the cavity 11. A second threading hole 13 is formed through one end of the side wall of the anchor body 1 on the same side as the first threading hole 12 and away from the limiting plate 4, and the second threading hole 13 is connected to the cavity 11. The developing line 2 passes through the first threading hole 12 and the second threading hole 13 in sequence. A first groove 5 is formed on the side wall of the anchor body 1 between the first threading hole 12 and the second threading hole 13 along its length direction, and a plurality of first threading coils 51 are fixed in the first groove 5 along its length direction. In the embodiment of the present application, five first threading coils 51 are provided, and the five first threading coils 51 are evenly spaced along the length direction of the first groove 5, and the developing line 2 passes through all the first threading coils 51.
[0037] refer to Figure 2 The side wall of the anchor body 1 away from the first threading hole 12 is penetrated with a fifth threading hole 16 and a sixth threading hole 17, both of which are connected to the cavity 11. The fifth threading hole 16 is opened at the end of the anchor body 1 away from the limiting plate 4, and the sixth threading hole 17 is opened at the end of the anchor body 1 away from the fifth threading hole 16. The developing line 2 passes through the fifth threading hole 16 and the sixth threading hole 17 in sequence. The side wall of the anchor body 1 between the fifth threading hole 16 and the sixth threading hole 17 is opened along the length direction of the anchor body 1. A third groove 7 is opened along the length direction of the anchor body 1. A plurality of third threading coils 71 are fixed in the third groove 7 along the length direction of the anchor body 1. In the embodiment of the present application, five third threading coils 71 are provided, and the five third threading coils 71 are evenly spaced along the length direction of the third groove 7. The developing line 2 passes through all the third threading coils 71.
[0038] When medical staff pull the developing wire 2, the developing wire 2 slides within the first wire-passing coil 51 and the third wire-passing coil. The developing wires 2 on both sides of the anchor body 1 contract and squeeze the side wall of the anchor body 1. At the same time, the side wall of the anchor body 1 is squeezed by the bottom wall of the anchor body 1, thereby gradually contracting the side wall of the anchor body 1.
[0039] Reference Figure 1 and Figure 3 , at both ends of the bottom wall of the anchor body 1, a third wire-passing hole 14 and a fourth wire-passing hole 15 are respectively formed through the bottom wall in an inclined direction. The third wire-passing hole 14 is formed on one side of the bottom wall of the anchor body 1 close to the second wire-passing hole 13, and the fourth wire-passing hole 15 is formed on one side of the bottom wall of the anchor body 1 away from the third wire-passing hole 14. Both the third wire-passing hole 14 and the fourth wire-passing hole 15 communicate with the cavity 11, and the tops of the third wire-passing hole 14 and the fourth wire-passing hole 15 approach each other. The developing wire 2 sequentially passes through the third wire-passing hole 14 and the fourth wire-passing hole 15. On the bottom wall of the anchor body 1 between the third wire-passing hole 14 and the fourth wire-passing hole 15, a second groove 6 is formed along the width direction of the anchor body 1. A plurality of second wire-passing coils 61 are fixedly arranged in the second groove 6 along the length direction of the second groove 6. In the embodiment of the present application, five second wire-passing coils 61 are provided, and the five second wire-passing coils 61 are evenly spaced along the length direction of the second groove 6. The developing wire 2 passes through all the second wire-passing coils 61.
[0040] When medical staff pull the developing wire 2, the developing wire 2 slides within the second wire-passing coil 61. The developing wire 2 outside the bottom wall of the anchor body 1 contracts and squeezes the bottom wall of the anchor body 1, so that the bottom wall of the anchor body 1 gradually contracts.
[0041] Reference Figure 4 , a support ball 3 is arranged in the cavity 11 of the anchor body 1. Through holes 31 for the developing wire 2 to pass through are formed through the side walls on both sides of the support ball 3.
[0042] When medical staff pull the developing wire 2, the developing wire 2 slides along the through hole 31, and the developing wire 2 drives the support ball 3 to move. The side wall and the bottom wall of the anchor body contract and wrap around the periphery of the support ball 3.
[0043] The implementation principle of the all-suture anchor with a developing function in the embodiment of the present application is as follows: Medical staff first insert the anchor body 1 into a prefabricated bone tunnel through an inserter, and pull the two free ends of the developing wire 2 to gradually tighten the developing wire 2. At this time, the side wall and the bottom wall of the anchor body 1 gradually bend and deform until the anchor body 1 shrinks into a mass and wraps around the periphery of the support ball 3. Through the above structure, the anchoring effect of the anchor body 1 is improved.
[0044] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
