Technical Field
[0001] This invention belongs to the field of orthopedic fixation implants, and in particular relates to a winged orthopedic anchor and its system. Background Technology
[0002] With the rapid development of the social economy and the improvement of people's living standards, the demand for the medical industry is increasing. In cases of bone injury and tearing of bone and soft tissue, orthopedic anchors are often used to connect bone to the body's soft tissue in order to repair the injury and promote healing.
[0003] Existing orthopedic anchors can be categorized by shape into winged anchors, stepped anchors, threaded anchors, irregularly shaped anchors, and suture anchors. Among these, winged anchors increase implantation reliability and pull-out resistance through the opening of the lateral anchor wings. This structure allows for faster implantation into bone tissue and facilitates the procedure.
[0004] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the existing fixed wings of the winged anchors adopt an active elastic expansion method, and the length and elasticity of the fixed wings will cause the fixed seams to generate greater cyclic displacement.
[0005] Based on the above problems, a fixation implant and its system are proposed. Summary of the Invention

[0040] 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.
[0041] Example 1: A fixation implant system, the system including an implant and an installation handle;
[0042] An implant consists of the implant body and implant auxiliary components;
[0043] The implant body consists of a suture segment and a fixation segment, and the implant body is made of an elastic material;
[0044] The fixed section has an installation through hole for installing the implant auxiliary component. Multiple fixing wings are provided on the side of the through hole. The fixing wings can be cut out from the outer wall of the fixed section by setting multiple cutting grooves. The inner wall of the fixing wings is located in the installation through hole. The wire section has a wire groove.
[0045] Multiple linearly distributed fixed wing groups are provided on the side of the through hole, and the fixed wing groups are arranged in a circular pattern.
[0046] The implant auxiliary component has a cross-sectional profile that matches the mounting through hole, and the side of the implant auxiliary component has an opening protrusion that abuts against the inner wall of the fixing wing.
[0047] Install the handle, including the grip and the insertion part;
[0048] The grip section is used for grasping during operation;
[0049] The insertion part is a long tube, which contains a control mounting rod for controlling the movement of the implant auxiliary components.
[0050] When using this system, the implant is installed at the front end of the insertion part. The insertion part installs the implant into the mounting hole through a pre-established channel. The implant auxiliary component is driven to move by controlling the mounting rod. The change in the contact position between the opening boss on the implant auxiliary component and the inner wall of the fixing wing causes the fixing wing to open, thus fixing the implant. The contact limit of the opening boss can reduce the elastic rebound of the fixing wing, ensuring the fixation strength and reducing cyclic displacement.
[0051] It should be noted that after the implant is fixed, as the body moves, the sutures apply a tension force to the implant through the gap. The maximum displacement of the implant each time it is subjected to tension is the cyclic displacement. The smaller the displacement, the better the traction fixation effect can be guaranteed.
[0052] The inner side of the fixed wing is an inwardly inclined surface, and the first fixed wing gradually thickens from the opening end to the connecting end.
[0053] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings; for example Figures 1-3 As shown, the system includes a fixation implant 1 and a grip handle 2. A telescopic mounting rod 35 is movably installed inside the grip handle 2, and the fixation implant 1 is movably installed at the distal end of the grip handle 2.
[0054] The grip handle 2 includes a grip portion 202 and an insertion rod 201. The grip portion 202 has an installation through hole 211. The insertion rod 201 is installed at the far end of the grip portion 202. The telescopic mounting rod 35 is movably installed in the insertion rod 201 and the installation through hole 211.
[0055] like Figures 4-6 As shown, the fixation implant 1 includes a fixation implant body 10 and an implant auxiliary component 12;
[0056] The fixed implant body 10 includes a threading part 110 and a fixing part 101. The threading part 110 is provided with a threading groove 103, and a suture is threaded through the threading groove 103.
[0057] The fixing part 101 is provided with an auxiliary component mounting hole 105 for installing the implant auxiliary component 12. The side of the auxiliary component mounting hole 105 is provided with a plurality of positioning linear grooves 106. A first fixing wing 109 is provided in the positioning linear groove 106. The distal end of the first fixing wing 109 is fixedly connected to the threading part 110 or the fixing part 101.
[0058] The implant auxiliary component 12 is movably installed in the auxiliary component mounting hole 105. The side of the implant auxiliary component 12 is provided with a plurality of positioning linear protrusions 125 that cooperate with the positioning linear groove 106. The positioning linear protrusions 125 are disposed in the positioning linear groove 106, and the outer side of the positioning linear protrusions 125 abuts against the inner side of the first fixed wing 109.
[0059] With this design, during use, the implant 1 is installed at the front end of the insertion rod 201. The insertion rod 201 installs the implant 1 into the mounting hole through a pre-established channel. By controlling the telescopic mounting rod 35, the implant auxiliary component 12 is driven to move. The position of the positioning linear protrusion 125 on the implant auxiliary component 12 against the inner wall of the first fixing wing 109 changes, causing the first fixing wing 109 to open and complete the fixation of the implant. It should be noted that the movement of the implant auxiliary component 12 can be upward, downward, rotational, or a combination of multiple movements. As long as the implant auxiliary component 12 and the implant body 10 produce relative movement and the position of the positioning linear protrusion 125 against the inner wall of the first fixing wing 109 changes, all methods disclosed in the prior art are the disclosure of this application.
[0060] Furthermore, the thread groove 103 is provided with a thread positioning block 104, and all transition angles of the thread positioning block 104 are rounded, which can avoid wear on the thread.
[0061] Furthermore, the telescopic mounting rod 35 can be driven by directly applying axial force, such as by the operator striking or pulling it; or by screwing it in.
[0062] Furthermore, an adjustment block mounting hole 212 is provided near the mounting through hole 211. An adjustment mounting block 3 is movably installed in the adjustment block mounting hole 212. The far end of the adjustment mounting block 3 is connected to the telescopic mounting rod 35. The connection between the telescopic mounting rod 35 and the adjustment mounting block 3 can be achieved by using glue, threads, or other fixed connection methods, or by using a coupling, rotatable boss, etc. The purpose of using a rotatable boss is to allow the telescopic mounting rod 35 to rotate asynchronously when the adjustment mounting block 3 rotates, so that the telescopic mounting rod 35 can only perform axial reciprocating motion and avoid unnecessary friction.
[0063] Furthermore, the adjusting block mounting hole 212 is a threaded hole 213, and the adjusting mounting block 3 is provided with a thread that mates with the threaded hole 213. The adjusting mounting block 3 is movably installed in the adjusting block mounting hole 212, so that the installation position of the adjusting mounting block 3 can be changed by rotating the adjusting mounting block 3, thereby driving the movement of the telescopic mounting rod 35.
[0064] In this disclosure, "remote end" and "front end" refer to the end furthest from the operator, while "near end" and "rear end" refer to the end closest to the operator.
[0065] In some embodiments, the sutures on the fixed implant 1 pass through the end face of the insertion rod 201, and the fixed implant 1 is positioned and fixed on the end face of the insertion rod 201 by the traction of the sutures. In some embodiments, the distal end of the insertion rod 201 has two symmetrically arranged first suture grooves 204, and the distal end face of the insertion rod 201 has an implant installation interface 206. The implant installation interface 206 has second suture grooves 207 on both sides. The cross-section of the implant installation interface 206 matches the auxiliary component installation hole 105. When the fixed implant 1 is installed, the implant installation interface 206 is movably installed in the auxiliary component installation hole 105 to ensure the stability of the fixed implant 1 installation. The sutures on the fixed implant 1 pass through the second suture grooves 207 and exit through the first suture grooves 204. After passing through the insertion rod 201, they are wound around the holding part 202. The holding part 202 has a winding boss 203 for winding the sutures.
[0066] Example 2: The purpose of this example is to disclose a specific structure of the fixation implant 1 and a fixation implant system, including the fixation implant 1, based on Example 1.
[0067] The fixation implant 1 includes a fixation implant body 10 and an implant auxiliary component 12;
[0068] The fixed implant body 10 includes a threading part 110 and a fixing part 101. The threading part 110 is provided with a threading groove 103, and a suture is threaded through the threading groove 103.
[0069] The fixing part 101 is provided with an auxiliary component mounting hole 105 for installing the implant auxiliary component 12. The side of the auxiliary component mounting hole 105 is provided with a plurality of positioning linear grooves 106. A first fixing wing 109 is provided in the positioning linear groove 106. The distal end of the first fixing wing 109 is fixedly connected to the threading part 110 or the fixing part 101. The inner side of the first fixing wing 109 is an inwardly inclined surface 102. The first fixing wing 109 gradually thickens from the proximal end to the distal end. The implant auxiliary component 12 is movably installed in the auxiliary component mounting hole 105. The side of the implant auxiliary component 12 is provided with a plurality of positioning linear protrusions 125 that cooperate with the positioning linear grooves 106. The positioning linear protrusions 125 are disposed in the positioning linear grooves 106. The outer side of the positioning linear protrusions 125 abuts against the inner side of the first fixing wing 109. The outer inclined surface 126 of the positioning linear boss 125 is inclined and matches the inner inclined surface 102. The outer inclined surface 126 is provided on the outer side of the positioning linear boss 125, and the contact surface of the opening boss on the outer inclined surface 126 matches the inner inclined surface 102. The height of the positioning linear boss 125 near the proximal end is higher than its distal end. In use, the implant auxiliary component 12 is first inserted into the auxiliary component mounting hole 105 from the proximal end face of the auxiliary component mounting hole 105. The positioning linear boss 125 is set in the positioning linear groove 106. The outer inclined surface 126 and the inner inclined surface 102 are in contact with each other. The matching inclined surfaces can ensure a larger contact area and avoid fatigue caused by force concentration and reciprocating force in the later stage. In this embodiment, the implant auxiliary component 12 opens the first fixed wing 109 by moving downward. The installation and fixation can be completed by directly contacting the telescopic mounting rod 35 downward.
[0070] In some embodiments, the threading groove 103 is connected to the auxiliary component mounting hole 105, and a suture positioning block 104 is provided in the threading groove 103. The suture is installed on the suture positioning block 104, and both ends of the suture pass through the auxiliary component mounting hole 105. This can prevent the suture from being damaged by the first fixing wing 109 due to being arranged on both sides of the fixed implant body 10.
[0071] Furthermore, the implant auxiliary component 12 is provided with a suture clearance through hole 121, and the suture installed on the suture positioning block 104 passes through the suture clearance through hole 121, so as to avoid the suture being squeezed by the implant auxiliary component 12 and the fixed implant body 10, which would cause it to break and fail.
[0072] When setting the suture clearance through hole 121, the proximal end of the suture clearance through hole 121 is provided with a mounting abutment boss 127, and a through hole is opened on the mounting abutment boss 127. This allows the end face of the telescopic mounting rod 35 to easily contact the implant auxiliary component 12, increasing its contact area and ensuring the stability when pushing the implant auxiliary component 12 to move.
[0073] Furthermore, the first fixing wing 109 is integrally formed with the fixing part 101. The first fixing wing 109 is set by cutting through multiple fixing wing cutting grooves 108. The materials of the fixing implant body 10 and the implant auxiliary component 12 can be metal materials such as titanium alloy and stainless steel, or medical plastics such as polyetheretherketone.
[0074] The cross-section of the implant auxiliary component 12 and the auxiliary component mounting hole 105 described in this disclosure can be circular, elliptical, or square, with a square shape being preferred. This can ensure the thickness of the four sides, thereby ensuring the overall strength. If a circular shape is used, in order to ensure the elasticity of the fixing wing, its thickness must not be too thick, which will affect the overall strength of the fixing part 101.
[0075] Furthermore, the outer surfaces of the auxiliary component mounting hole 105 and the implant auxiliary component 12 are respectively provided with a plurality of mutually cooperating anti-dislodgement grooves or anti-dislodgement protrusions. The anti-dislodgement protrusions are in a unidirectional inclined position so that the reverse movement is limited to ensure stability.
[0076] In some disclosures, the cross-section of the implant auxiliary component 12 is generally square, the positioning linear protrusions 125 are disposed at the four corners of the square, the auxiliary component mounting holes 105 are adapted to the implant auxiliary component 12, the auxiliary component mounting holes 105 are provided with evenly distributed one-way anti-dislodgement grooves 107 inside the four sides, and the outer surface 120 of the implant auxiliary component 12 is provided with a plurality of one-way anti-dislodgement protrusions 122 that cooperate with the one-way anti-dislodgement grooves 107.
[0077] Furthermore, such as Figure 5 As shown, the implant auxiliary component 12 is provided with an anti-dislodgement protrusion inclined surface 123. One end of the anti-dislodgement protrusion inclined surface 123 is a stop surface 124. During installation, the anti-dislodgement protrusion inclined surface 123 plays a guiding role, allowing the implant auxiliary component 12 to be installed more smoothly into the auxiliary component mounting hole 105. The anti-dislodgement protrusion inclined surface 123 acts as a guide inclined surface. After installation, the one-way anti-dislodgement protrusion 122 is inserted into the one-way anti-dislodgement groove 107. The direction of the stop surface 124 is opposite to the movement direction of the implant auxiliary component 12. The stop surface 124 abuts against the side of the one-way anti-dislodgement groove 107, thus preventing the implant auxiliary component 12 from returning to its original position and realizing the one-way movement of the implant auxiliary component 12.
[0078] Furthermore, both the implant auxiliary component 12 and the fixed implant body 10 are made of materials with some elasticity, such as stainless steel, titanium alloy, and PEEK material.
[0079] Example 3: The purpose of this example is to disclose a specific structure for the fixation implant 1 based on Example 1, as shown in the figure, telescopic mounting rod 4- Figure 6 As shown, a fixation implant system includes a fixation implant 1;
[0080] The fixation implant 1 includes a fixation implant body 10 and an implant auxiliary component 12;
[0081] The fixed implant body 10 includes a fixation part 101;
[0082] The fixing part 101 is provided with an auxiliary component mounting hole 105 for installing the implant auxiliary component 12. The side of the auxiliary component mounting hole 105 is provided with a plurality of positioning linear grooves 106. A first fixing wing 109 is provided in the positioning linear groove 106. The side of the first fixing wing 109 near the proximal end face of the fixing part 101 is fixedly connected to the fixing part 101. The inner side of the first fixing wing 109 is an inwardly inclined surface 102. The first fixing wing 109 gradually becomes thinner from the proximal end to the distal end. The first fixing wing 109 can be integrally set with the fixing part 101. Multiple first fixing wings 109 are cut out on the outside of the auxiliary component mounting hole 105 by fixing wing cutting groove 108.
[0083] Furthermore, the side of the first fixed wing 109 closest to the near end face of the fixed part 101 is a connecting section, and the side of the first fixed wing 109 furthest from the connecting end is an open end.
[0084] The implant auxiliary component 12 is movably installed within the auxiliary component mounting hole 105. The side of the implant auxiliary component 12 is provided with multiple positioning linear protrusions 125 that cooperate with the positioning linear groove 106. The positioning linear protrusions 125 are disposed within the positioning linear groove 106, and their outer sides abut against the inner side of the first fixing wing 109. The outer inclined surface 126 of the outer side of the positioning linear protrusion 125 is inclined and matches the inner inclined surface 102. The height of the positioning linear protrusion 125 near its proximal end is lower than its distal end height.
[0085] The implant auxiliary component 12 has a suture clearance through hole 121, and a suture fixing post 129 is provided in the suture clearance through hole 121. The suture passes through the suture fixing post 129 and is fixed on both sides of the suture fixing post 129. The suture installed on the suture fixing post 129 passes through the suture clearance through hole 121.
[0086] In use, the implant auxiliary component 12 is first inserted into the auxiliary component mounting hole 105 from the distal end face of the auxiliary component mounting hole 105. The positioning linear boss 125 is set in the positioning linear groove 106. The outer inclined surface 126 and the inner inclined surface 102 are in contact with each other. Setting the mutually matching inclined surfaces can ensure a larger contact area and avoid fatigue caused by force concentration and reciprocating force in the later stage. In this embodiment, the implant auxiliary component 12 opens the first fixed wing 109 by moving upward. The installation and fixation are completed directly by pulling the implant auxiliary component 12 upward. At this time, the implant auxiliary component 12 is fixed by the contact between the outer inclined surface 126 and the inner inclined surface 102.
[0087] In this design, the opening of the first fixing wing 109 faces the distal end of the implant 1. Fixation is achieved by the outer side of the first fixing wing 109 abutting against the inner wall of the pre-drilled mounting hole. In some disclosures, friction-increasing stripes can be provided on the outer side of the first fixing wing 109 to ensure effectiveness. This design avoids the need for additional suture threading at the distal end of the implant body 10, thus maintaining the same installation strength while reducing the length of the implant 1. Within the same length, this design increases the fastening force.
[0088] In some disclosed embodiments of this invention, the positioning linear groove 106 is provided with a first fixing wing 109. The side of the first fixing wing 109 near the distal end face of the fixing part 101 is fixedly connected to the fixing part 101. The inner side of the first fixing wing 109 is provided with an inwardly inclined surface 102. The first fixing wing 109 gradually becomes thicker from the proximal end to the distal end.
[0089] The implant auxiliary component 12 is movably installed within the auxiliary component mounting hole 105. The side of the implant auxiliary component 12 is provided with multiple positioning linear protrusions 125 that cooperate with the positioning linear groove 106. The positioning linear protrusions 125 are disposed within the positioning linear groove 106. The outer side of the auxiliary component mounting hole 105 abuts against the inner side of the first fixing wing 109.
[0090] In use, the implant auxiliary component 12 is first inserted into the auxiliary component mounting hole 105 from the distal end face of the auxiliary component mounting hole 105. The positioning linear boss 125 is set in the positioning linear groove 106. The outer side of the auxiliary component mounting hole 105 abuts against the inner side of the first fixing wing 109. In this embodiment, the implant auxiliary component 12 opens the first fixing wing 109 by moving upward. The installation and fixation are completed directly by pulling the implant auxiliary component 12 upward. The first fixing wing 109 is gradually thickened from the proximal end to the distal end, which ensures that the opening angle of the first fixing wing 109 gradually increases as the implant auxiliary component 12 moves.
[0091] In this design, the opening of the first fixing wing 109 faces the proximal end of the implant 1. Fixation is achieved by the outer surface of the first fixing wing 109 contacting the inner wall of the pre-drilled mounting hole. When the implant body 10 is subjected to a pulling force towards the proximal end, the opening angle of the first fixing wing 109 increases. Thus, as the implant body 10 is subjected to tension, the pressure between the first fixing wing 109 and the inside of the mounting hole gradually increases, ensuring strength. In some disclosures, friction-increasing stripes can be provided on the outer surface of the first fixing wing 109 to ensure effectiveness. This design avoids the need for an additional portion at the distal end of the implant body 10 used for threading, reducing the length of the implant 1 while maintaining the same installation strength. At the same length, the fastening force can be increased.
[0092] The outer inclined surface 126 of the positioning linear boss 125 is inclined to match the inner inclined surface 102, and the height of the positioning linear boss 125 near its proximal end is lower than its distal end height.
[0093] The implant auxiliary component 12 has a suture clearance through hole 121, and a suture fixing post 129 is provided in the suture clearance through hole 121. The suture passes through the suture fixing post 129 and is fixed on both sides of the suture fixing post 129. The suture installed on the suture fixing post 129 passes through the suture clearance through hole 121.
[0094] In use, the implant auxiliary component 12 is first inserted into the auxiliary component mounting hole 105 from the distal end face of the auxiliary component mounting hole 105. The positioning linear boss 125 is set in the positioning linear groove 106. The outer inclined surface 126 and the inner inclined surface 102 are in contact with each other. Setting the mutually matching inclined surfaces can ensure a larger contact area and avoid fatigue caused by force concentration and reciprocating force in the later stage. In this embodiment, the implant auxiliary component 12 opens the first fixing wing 109 by moving upward. The installation and fixation are completed directly by pulling the implant auxiliary component 12 upward. At this time, the implant auxiliary component 12 is fixed by the contact between the outer inclined surface 126 and the inner inclined surface 102.
[0095] In some implementations, the mounting abutment 127 is provided with an adjustment threaded hole 128, and the adjustment mounting block 3 includes;
[0096] The adjusting block body 31 is movably installed in the adjusting block mounting hole 212;
[0097] A telescopic mounting rod 35 is movably installed inside the adjusting block body 31. The telescopic mounting rod 35 is movably installed inside the insertion rod 201. The distal end of the telescopic mounting rod 35 is provided with a connecting thread 351, which cooperates with the adjusting thread hole 128.
[0098] An adjustment knob 34 is movably installed inside the adjustment block body 31, and the adjustment knob 34 is fixedly connected to the telescopic mounting rod 35.
[0099] With this design, during installation, the implant auxiliary component 12 is inserted from the distal end of the auxiliary component mounting hole 105, and the implant auxiliary component 12 is installed onto the connecting thread 351 through the adjusting thread hole 128; after holding the handle and inserting the insertion rod 201 into the channel, the implant 1 is fixed and installed into the pre-hole on the bone. An upward pulling force is applied to the adjusting knob 34, which pulls the implant auxiliary component 12 upward so that the first fixing wing 109 opens to fix the implant 1.
[0100] Furthermore, the implant auxiliary component 12 can directly fix the implant 1 by pulling the suture. At this time, the installation and insertion device for fixing the implant 1 does not need to be equipped with the telescopic installation rod 35, which is more convenient and faster.
[0101] In some implementations, such as Figure 7 As shown, the structure of the fixation body is as follows: the multi-fixation wing body 130 is hollow tubular, and multiple fixation wing mounting slots 1301 are provided inside the multi-fixation wing body 130. Multiple small fixation wings 1302 are provided on the fixation wing mounting slots 1301. Multiple positioning protrusions that cooperate with the fixation wing mounting slots 1301 are provided on the outer side of the implant auxiliary component 12. The positioning protrusions are provided with abutting protrusions to abut against and open the small fixation wings 1302. Through this design, the multi-fixation wing body 130 can have more points of contact with the bone wall, which can ensure a better fixation effect. At the same time, the length of the fixation wings is significantly reduced compared to individual fixation wings, which can reduce the deformation when under tension.
[0102] In some implementations, such as Figure 8 As shown, the fixing device includes a multi-wing anti-detachment body 1101 and a multi-wing anti-detachment auxiliary component 1200. The multi-wing anti-detachment body 1101 has a tubular structure. The inner wall of the multi-wing anti-detachment body 1101 is provided with a plurality of second fixed wing mounting grooves 1102. The second fixed wing mounting grooves 1102 are provided with a plurality of second fixed wings 1104. The inner wall of the second fixed wing 1104 is set with a slope so as to make way for the protrusions that abut the opening of the second fixed wing 1104.
[0103] The outer side of the multi-fixed-wing anti-detachment auxiliary component 1200 is provided with multiple positioning bosses that cooperate with the second fixed-wing mounting groove 1102. The positioning bosses are provided with multiple fixed-wing opening contact bosses 1202 for abutting against the second fixed-wing 1104 to open it. The fixed-wing opening contact bosses 1202 are provided with guide slopes 1203 and contact planes 1204. During installation, the multi-fixed-wing anti-detachment auxiliary component 1200 is inserted from the multi-fixed-wing anti-detachment body 1101 so that the fixed-wing opening contact bosses 1202 and the second fixed-wing 1104 are staggered in sequence. During fixing, the multi-fixed-wing anti-detachment auxiliary component 1200 is pulled forward relative to the multi-fixed-wing anti-detachment body 1101 so that the contact position between the second fixed-wing 1104 and the inner side of the second fixed-wing 1104 changes so that it opens and completes the fixing.
[0104] Furthermore, the inner wall of the multi-fixed-wing anti-detachment body 1101 is provided with a plurality of linearly distributed one-way anti-detachment grooves 1103, and the outer wall of the multi-fixed-wing anti-detachment auxiliary component 1200 is provided with one-way anti-detachment bosses 1201 that cooperate with the one-way anti-detachment grooves 1103.
[0105] Furthermore, the lowest part of the positioning boss is provided with a locking boss 1205, and the locking boss 1205 is provided with a locking plane 1206. The locking boss 1205 is similar in structure to the fixed wing opening contact boss 1202, the difference being that the length of the locking plane 1206 is less than that of the contact plane 1204. The lowest part of the second fixed wing mounting groove 1102 is provided with a locking fixed wing 1105 that cooperates with the locking boss 1205. The inner side of the locking fixed wing 1105 is provided with a locking guide slope 1107, and the upper end of the locking guide slope 1107 is provided with a locking boss 1106. In this way, when the multi-fixed wing anti-detachment auxiliary component 1200 moves into place, the lower end of the locking plane 1206 abuts against the upper end of the locking guide slope 1107, thus preventing the multi-fixed wing anti-detachment auxiliary component 1200 from returning to its original position and ensuring the fixation is firm.
[0106] In some implementations, such as Figures 9-11 As shown, the adjusting block body 31 has threads on its outer side and is installed in the threaded hole 213. The adjusting block body 31 has a first mounting groove 3101, a second mounting groove 3104, and a telescopic rod mounting groove 3103 sequentially formed from the proximal end to the distal end. The telescopic mounting rod 35 passes through the telescopic rod mounting groove 3103. The inner wall of the first mounting groove 3101 is provided with a first one-way ratchet tooth 3102.
[0107] A one-way adjustment knob 32 is movably installed in the first mounting groove 3101. The far end of the one-way adjustment knob 32 is provided with a third mounting groove 3203 that is connected to the telescopic mounting rod 35. The inner wall of the third mounting groove 3203 is provided with a second one-way ratchet 3205. The telescopic mounting rod 35 is provided with teeth that cooperate with the second one-way ratchet 3205.
[0108] The one-way adjustment knob 32 has a first gear 3201 near its end, which engages with the first one-way ratchet tooth 3102. The one-way adjustment knob 32 has an adjustment plate connection hole 3202 near its end face, and an adjustment plate positioning groove 3204 is provided in the adjustment plate connection hole 3202. The adjustment block body 31 has an end face fixing ring 33 near its end for fixing the one-way adjustment knob 32. The second one-way ratchet 3205 and the first one-way ratchet tooth 3102 are in opposite directions.
[0109] An adjustment knob 34 is installed on the adjustment disc connection hole 3202. The adjustment knob 34 is provided with a quick-connect boss 3401, which is installed inside the adjustment disc connection hole 3202.
[0110] With this design, during installation, the implant auxiliary component 12 is inserted from the distal end of the auxiliary component mounting hole 105, and then installed onto the connecting thread 351 through the adjusting thread hole 128. Holding the handle, the insertion rod 201 is inserted into the channel, and the implant 1 is then installed into the pre-drilled hole in the bone. Rotating the adjusting knob 34 causes the first gear 3201 to drive the adjusting block body 31 to rotate. The second one-way ratchet 3205 rotates in the same direction as the ratchet's tilt. 3025 does not drive the telescopic mounting rod 35 to move. The adjusting block body 31 applies an upward pulling force to the telescopic mounting rod 35. The mounting holes 35 and 3023 are equipped with axial limiting rings to ensure that the tension can be transmitted. The traction implant auxiliary component 12 moves upward, causing the first fixing wing 109 to open and fix the implant 1. After the implant auxiliary component 12 is installed in place, the adjustment knob 34 is rotated in the opposite direction. The rotation direction of the one-way adjustment knob 32 is consistent with the tilt direction of the first one-way ratchet tooth 3102. The first gear 3201 does not drive the adjustment block body 31 to move. The second one-way ratchet 3205 drives the telescopic mounting rod 35 to rotate, causing 3501 to unscrew the implant auxiliary component 12 to release the fixation. Then, the insertion rod 201 is taken out from the channel to complete the installation.
[0111] Furthermore, the external threads on the 3501 and the adjustment block body 31 are in opposite directions.
