[0002] With the rapid development of social economy and the improvement of people's living standards, the demand for the medical industry is growing. In cases of bone injury and bone and soft tissue tear, orthopedic fixation devices are often needed to connect bones to human soft tissue to repair injuries and promote healing.

[0003] Existing orthopedic fixation devices can be divided into winged fixation devices, step fixation devices, threaded fixation devices, special-shaped fixation devices, and full-suture fixation devices according to the shape of the fixation device; among them, the winged fixation device increases the implantation reliability and anti-pullout ability of the fixation device by opening the side wings of the fixation device. This structure makes it faster and easier to operate when implanted into bone tissue.

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the fixing wings of the existing winged fixing device are actively elastically expanded, and the length and elasticity of the fixing wings will cause the sutures fixed thereto to produce a larger cyclic displacement.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1, a fixation implant system, the system comprising an implant and a mounting handle;

[0038] Implant, including implant body and implant auxiliary components;

[0039] The implant body is composed of a threading segment and a fixing segment. The implant body is made of elastic material, and the specific material may be stainless steel, titanium alloy, peek material, etc.

[0040] A mounting through hole for mounting an implant auxiliary component is provided in the fixing section, a plurality of fixing wings are provided on the side of the through hole, the fixing wings can be cut out from the outer wall of the fixing section by setting a plurality of cutting grooves, the inner wall of the fixing wings is located in the mounting through hole, and a threading groove is provided on the threading section;

[0041] The implant auxiliary component has a cross-sectional profile that matches the mounting through hole, and a side surface of the implant auxiliary component is provided with an open boss that contacts the inner wall of the fixed wing.

[0042] Install the handle, including a grip portion and an insertion portion;

[0043] The gripping part is used for gripping during operation;

[0044] The inserting part is in the shape of a long tube, and a control mounting rod for controlling the movement of the implant auxiliary component is arranged inside the inserting part.

[0045] When the system is in use, the implant is installed at the front end of the insertion part, and 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, and the opening boss on the implant auxiliary component changes the position of the interference with the inner wall of the fixed wing to open the fixed wing to complete the fixation of the implant; the elastic rebound of the fixed wing can be reduced by the interference limit of the opening boss to ensure the fixing strength and reduce the cyclic displacement.

[0046] It should be noted here that after the implant is fixed, as the human body moves, the sutures apply interstitial tension to the implant. The maximum displacement of the implant each time it is subjected to tension is the cyclic displacement. The smaller the displacement, the more effective the traction fixation effect can be.

[0047] The inner side of the fixed wing is an inner inclined surface, and the first fixed wing gradually becomes thicker from the opening end to the connection end.

[0048] The embodiments of the present disclosure are now described in detail with reference to the accompanying drawings; Figure 1-Figure 3 As shown, the system comprises a fixed implant 1 and a gripping handle 2, a telescopic mounting rod 35 is movably mounted in the gripping handle 2, and the fixed implant 1 is movably mounted at the distal end of the gripping handle 2;

[0049] The grip handle 2 includes a grip portion 202 and an insertion rod 201. The grip portion 202 is provided with a mounting hole 211. The insertion rod 201 is mounted at the distal end of the grip portion 202. The telescopic mounting rod 35 is movably mounted in the insertion rod 201 and the mounting hole 211.

[0050] like Figure 4-Figure 6 As shown, the fixation implant 1 comprises a fixation implant body 10 and an implant auxiliary component 12;

[0051] The fixed implant body 10 includes a threading portion 110 and a fixing portion 101. The threading portion 110 is provided with a threading groove 103, and a suture is passed through the threading groove 103.

[0052] The fixing part 101 is provided with an auxiliary component mounting hole 105 for installing the implant auxiliary component 12, and the side of the auxiliary component mounting hole 105 is provided with multiple positioning linear grooves 106, and the positioning linear grooves 106 are provided with a first fixing wing 109, and the distal end of the first fixing wing 109 is fixedly connected to the threading part 110 or the fixing part 101.

[0053] The implant auxiliary component 12 is movably installed in the auxiliary component installation hole 105, and a plurality of positioning linear bosses 125 that cooperate with the positioning linear groove 106 are provided on the side of the implant auxiliary component 12. The positioning linear bosses 125 are arranged in the positioning linear groove 106, and the outer side of the positioning linear bosses 125 abuts against the inner side of the first fixed wing 109.

[0054] Through such a design, when in use, the fixed implant 1 is installed at the front end of the insertion rod 201, and the insertion rod 201 installs the fixed implant 1 into the mounting hole through a pre-established channel. The implant auxiliary component 12 is driven to move by controlling the telescopic mounting rod 35. The positioning linear boss 125 on the implant auxiliary component 12 changes the position of the interference with the inner wall of the first fixed wing 109 to make the first fixed wing 109 open to complete the fixation of the implant. It should be noted here 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 fixed implant body 10 produce relative movement and the change of the position of the interference with the inner wall of the first fixed wing 109 adopts all the methods disclosed in the prior art, they are all the disclosed contents of this application.

[0055] Furthermore, a suture positioning block 104 is provided in the threading groove 103, and all transition angles of the suture positioning block 104 are rounded, so as to avoid wear of the suture.

[0056] Furthermore, the telescopic mounting rod 35 can be driven by directly applying an axial force, such as by knocking or pulling by an operator; or by screwing in a spiral.

[0057] Furthermore, an adjusting block mounting hole 212 is provided at the proximal end of the mounting through hole 211, and an adjusting mounting block 3 is movably installed in the adjusting block mounting hole 212. The distal end of the adjusting mounting block 3 is connected to the telescopic mounting rod 35. The telescopic mounting rod 35 and the adjusting mounting block 3 can be connected by a fixed connection method such as glue and thread, or by a coupling; a rotatable boss or the like. The purpose of using a rotatable boss is that the telescopic mounting rod 35 can rotate asynchronously when the adjusting mounting block 3 rotates, so that the telescopic mounting rod 35 can only perform axial reciprocating motion to avoid unnecessary friction.

[0058] Furthermore, the adjusting block mounting hole 212 is a threaded hole 213, and the adjusting mounting block 3 is provided with a thread that matches 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.

[0059] In the implementation of the present disclosure, the “distal end” or “front end” refers to the end away from the operator, and the “proximal end” or “rear end” refers to the end close to the operator.

[0060] In some embodiments, the sutures set on the fixed implant 1 are inserted from the end face of the insertion rod 201, and the positioning and fixation of the fixed implant 1 on the end face of the insertion rod 201 is completed by the traction of the sutures; in some embodiments, the distal end of the insertion rod 201 is provided with two symmetrically arranged first wiring grooves 204, and the distal end face of the insertion rod 201 is provided with an implant mounting interface 206, and second wiring grooves 207 are provided on both sides of the implant mounting interface 206. The cross-section of the implant mounting interface 206 matches the auxiliary component mounting hole 105. When the fixed implant 1 is installed, the implant mounting interface 206 is movably installed in the auxiliary component mounting hole 105 to ensure the stability of the installation of the fixed implant 1. The sutures on the fixed implant 1 are inserted from the second wiring groove 207 and exit from the first wiring groove 204. After passing through the insertion rod 201, they are wound around the gripping part 202, and the gripping part 202 is provided with a winding boss 203 for winding the sutures.

[0061] Embodiment 2: The purpose of this embodiment is to disclose a specific structure of a fixation implant 1 based on Embodiment 1, and a fixation implant system, including a fixation implant 1;

[0062] The fixed implant 1 comprises a fixed implant body 10 and an implant auxiliary component 12;

[0063] The fixed implant body 10 includes a threading portion 110 and a fixing portion 101. The threading portion 110 is provided with a threading groove 103, and a suture is passed through the threading groove 103.

[0064] The fixing part 101 is provided with an auxiliary component mounting hole 105 for mounting the implant auxiliary component 12, and the side of the auxiliary component mounting hole 105 is provided with a plurality of positioning linear grooves 106, and the positioning linear grooves 106 are provided with a first fixing wing 109, and the distal end of the first fixing wing 109 is fixedly connected to the threading part 110 or the fixing part 101, and the inner side of the first fixing wing 109 is an inner inclined surface 102, and the first fixing wing 109 gradually becomes thicker from the proximal end to the distal end;

[0065] The implant auxiliary component 12 is movably installed in the auxiliary component installation hole 105, and a plurality of positioning linear bosses 125 that cooperate with the positioning linear groove 106 are provided on the side of the implant auxiliary component 12. The positioning linear bosses 125 are arranged in the positioning linear groove 106, and the outer side of the positioning linear bosses 125 abuts against the inner side of the first fixed wing 109. The outer inclined surface 126 on the outer side of the positioning linear boss 125 is tilted to match the inner inclined surface 102. The height of the positioning linear boss 125 near the proximal position is higher than its distal height. When 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 contact each other. The setting of mutually matching inclined surfaces can ensure a larger contact area to avoid fatigue caused by concentrated force and then reciprocating force in the later stage. In this embodiment, the implant auxiliary component 12 opens the first fixed wing 109 by downward movement, and the installation and fixation can be completed directly by the downward resistance of the telescopic mounting rod 35.

[0066] 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 sutures arranged on both sides of the fixed implant body 10 from being damaged by being cut by the first fixed wing 109.

[0067] Furthermore, a suture clearance hole 121 is provided on the implant auxiliary component 12, and the suture installed on the suture positioning block 104 passes through the suture clearance hole 121, thereby preventing the suture from squeezing the implant auxiliary component 12 and the fixed implant body 10 and causing them to break and fail.

[0068] When setting the suture clearance hole 121, a mounting interference boss 127 is provided at the proximal end of the suture clearance hole 121, and a through hole is opened on the mounting interference boss 127, so that the end face of the telescopic mounting rod 35 can be easily contacted with the implant auxiliary component 12 to increase its contact area and ensure stability when pushing the implant auxiliary component 12 to move.

[0069] Furthermore, the first fixed wing 109 is integrally arranged with the fixed part 101, and the setting of the first fixed wing 109 is completed by cutting a plurality of fixed wing cutting grooves 108. The material of the fixed 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.

[0070] The cross-sections of the implant auxiliary component 12 and the auxiliary component mounting hole 105 described in the present disclosure can be circular, elliptical and square. Preferably, a square shape is adopted, which can ensure the thickness of the four sides and thus ensure the overall strength. If a circular shape is adopted, in order to ensure the elasticity of the fixing wing, it is necessary to ensure that the thickness cannot be too thick, which will affect the overall strength of the fixing part 101.

[0071] Furthermore, the auxiliary component mounting hole 105 and the outer side surface of the implant auxiliary component 12 are respectively provided with a plurality of anti-slip grooves or anti-slip bosses that cooperate with each other, and the position of the anti-slip bosses is unidirectionally inclined so that the reverse movement is limited to ensure stability.

[0072] In some disclosures, the cross-section of the implant auxiliary component 12 is a square as a whole, the positioning linear bosses 125 are arranged at the four corners of the square, the auxiliary component mounting hole 105 and the implant auxiliary component 12 are adapted to each other, the four sides of the auxiliary component mounting hole 105 are provided with uniformly distributed one-way anti-slip grooves 107, and the outer side surface 120 of the implant auxiliary component 12 is provided with a plurality of one-way anti-slip bosses 122 that cooperate with the one-way anti-slip grooves 107;

[0073] Furthermore, if Figure 5 As shown, the implant auxiliary component 12 is provided with an anti-slip boss bevel 123, and one end of the anti-slip boss bevel 123 is a stop surface 124. During installation, the anti-slip boss bevel 123 plays a guiding role, which can make the implant auxiliary component 12 more smoothly installed in the auxiliary component mounting hole 105. The anti-slip boss bevel 123 plays the role of a guiding bevel. After installation, the one-way anti-slip boss 122 is inserted into the one-way anti-slip groove 107. The direction in which the stop surface 124 is set is opposite to the movement direction of the implant auxiliary component 12. The stop surface 124 conflicts with the side of the one-way anti-slip groove 107, which can avoid the implant auxiliary component 12 from returning to its original position and realize the unidirectional movement of the implant auxiliary component 12.

[0074] Furthermore, the implant auxiliary component 12 and the fixed implant body 10 are both made of materials with some elasticity.

[0075] Embodiment 3: The purpose of this embodiment is to disclose a specific structure of the fixed implant 1 based on the embodiment 1, as shown in FIG. Figure 6 As shown, a fixation implant system comprises a fixation implant 1;

[0076] The fixed implant 1 comprises a fixed implant body 10 and an implant auxiliary component 12;

[0077] The fixation implant body 10 includes a fixation portion 101;

[0078] An auxiliary component mounting hole 105 for mounting an implant auxiliary component 12 is provided on the fixing portion 101, and a plurality of positioning linear grooves 106 are provided on the side of the auxiliary component mounting hole 105. A first fixing wing 109 is provided in the positioning linear groove 106. The first fixing wing 109 is fixedly connected to the fixing portion 101 on the side close to the proximal end face of the fixing portion 101, and the inner side of the first fixing wing 109 is an inner 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 arranged with the fixing portion 101, and a plurality of first fixing wings 109 can be cut out on the outer side of the auxiliary component mounting hole 105 through the fixing wing cutting groove 108.

[0079] Furthermore, a side of the first fixing wing 109 close to the proximal end surface of the fixing portion 101 is a connecting section, and a side of the first fixing wing 109 away from the connecting end is an open end.

[0080] The implant auxiliary component 12 is movably installed in the auxiliary component installation hole 105. A plurality of positioning linear bosses 125 that cooperate with the positioning linear groove 106 are provided on the side of the implant auxiliary component 12. The positioning linear bosses 125 are arranged in the positioning linear groove 106. The outer side of the positioning linear bosses 125 abuts against the inner side of the first fixed wing 109. The outer inclined surface 126 of the outer side of the positioning linear boss 125 is inclined to match the inner inclined surface 102. The height of the positioning linear boss 125 near the proximal end is lower than its distal end height.

[0081] The implant auxiliary component 12 is provided with a suture clearance through hole 121, in which a suture fixing column 129 is provided, and the suture passes through both sides of the suture fixing column 129 and is fixed on the suture fixing column 129, and the suture installed on the suture fixing column 129 passes through the suture clearance through hole 121;

[0082] When 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 arranged in the positioning linear groove 106, the outer inclined surface 126 and the inner inclined surface 102 are in contact with each other, and the mutually matching inclined surfaces can ensure a larger contact area to avoid fatigue caused by the reciprocating force in the later stage of force concentration. In this embodiment, the implant auxiliary component 12 opens the first fixing wing 109 by moving upward, and 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 interference between the outer inclined surface 126 and the inner inclined surface 102;

[0083] In this solution, the opening direction of the first fixing wing 109 is toward the distal end of the fixing implant 1, and the fixing is completed by the outer side of the first fixing wing 109 contacting the inner wall of the reserved installation hole. In some disclosures, stripes for increasing friction can be set on the outer side of the first fixing wing 109 to ensure the effect. Such a design can avoid the additional part for threading at the distal end of the fixing implant body 10 while ensuring the same installation strength, and the length of the fixing implant 1 can be reduced, and the tightening force can be improved at the same length.

[0084] In some disclosed solutions of this embodiment, a first fixing wing 109 is provided in the positioning linear groove 106, and the first fixing wing 109 is fixedly connected to the fixing portion 101 on one side close to the distal end surface of the fixing portion 101, and an inner inclined surface 102 is provided on the inner side of the first fixing wing 109, and the first fixing wing 109 gradually becomes thicker from the proximal end to the distal end.

[0085] The implant auxiliary component 12 is movably mounted in the auxiliary component mounting hole 105. A plurality of positioning linear bosses 125 cooperating with the positioning linear groove 106 are provided on the side of the implant auxiliary component 12. The positioning linear bosses 125 are arranged in the positioning linear groove 106. The outer side of the auxiliary component mounting hole 105 abuts against the inner side of the first fixed wing 109.

[0086] When 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, and the outer side of the auxiliary component mounting hole 105 is in conflict with the inner side of the first fixed wing 109. In this embodiment, the implant auxiliary component 12 opens the first fixed wing 109 by moving upward, and the installation and fixation are completed directly by pulling the implant auxiliary component 12 upward. The setting that the first fixed wing 109 gradually becomes thicker from the proximal end to the distal end can ensure that the opening angle of the first fixed wing 109 gradually increases with the movement of the implant auxiliary component 12;

[0087] In this solution, the opening direction of the first fixing wing 109 is toward the proximal end of the fixed implant 1, and the fixation is completed by the outer side of the first fixing wing 109 contacting the inner wall of the reserved installation hole. When the fixed implant body 10 is subjected to a pulling force toward the proximal end, the force on the first fixing wing 109 will increase the opening angle. As the fixed implant body 10 is subjected to a pulling force, the pressure inside the first fixing wing 109 and the installation hole will gradually increase to ensure strength. In some disclosures, stripes that increase friction can be set on the outer side of the first fixing wing 109 to ensure the effect. Such a design can avoid the additional part for threading at the distal end of the fixed implant body 10 while ensuring the same installation strength while reducing the length of the fixed implant 1, and can increase the tightening force at the same length.

[0088] The outer inclined surface 126 of the outer side of the positioning linear boss 125 is tilted to match the inner inclined surface 102, and the height of the positioning linear boss 125 near the proximal end is lower than the height of the distal end;

[0089] The implant auxiliary component 12 is provided with a suture clearance through hole 121, in which a suture fixing column 129 is provided, and the suture passes through both sides of the suture fixing column 129 and is fixed on the suture fixing column 129, and the suture installed on the suture fixing column 129 passes through the suture clearance through hole 121;

[0090] When in use, first insert the implant auxiliary component 12 from the distal end face of the auxiliary component mounting hole 105 into the auxiliary component mounting hole 105, the positioning linear boss 125 is arranged in the positioning linear groove 106, the outer inclined surface 126 and the inner inclined surface 102 contact each other, and the setting of mutually matching inclined surfaces can ensure a larger contact area to avoid fatigue caused by concentrated force and then reciprocating force in the later stage. In this embodiment, the implant auxiliary component 12 opens the first fixed wing 109 by an upward movement, and 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 interference between the outer inclined surface 126 and the inner inclined surface 102.

[0091] In some implementations, the mounting abutment boss 127 is provided with an adjustment threaded hole 128, and the adjustment mounting block 3 includes;

[0092] The adjusting block body 31 is movably mounted in the adjusting block mounting hole 212;

[0093] A telescopic mounting rod 35 is movably mounted in the adjusting block body 31, and the telescopic mounting rod 35 is movably mounted in the inserting rod 201. A connecting thread 351 is provided at the distal end of the telescopic mounting rod 35, and the connecting thread 351 cooperates with the adjusting thread hole 128.

[0094] An adjusting knob 34 is movably installed in the adjusting block body 31, and the adjusting knob 34 is fixedly connected to the telescopic mounting rod 35;

[0095] Through such a design, during installation, the implant auxiliary component 12 is inserted and installed from the distal end of the auxiliary component installation hole 105, and the implant auxiliary component 12 is installed on the connecting thread 351 through the adjusting threaded hole 128; after holding the handle and inserting the insertion rod 201 into the channel, the fixed implant 1 is installed into the pre-hole on the bone, and an upward pulling force is applied to the adjusting knob 34 to pull the implant auxiliary component 12 upward so that the first fixing wing 109 opens to complete the fixation of the fixed implant 1.

[0096] Furthermore, the implant auxiliary component 12 directly fixes 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 provided with the telescopic installation rod 35, which is more convenient and quick.

[0097] In some implementations, such as Figure 7 As shown, the structure of the fixture body is like a multi-fixed wing body 130, and the multi-fixed wing body 130 is in the shape of a hollow tube. A plurality of fixed wing mounting grooves 1301 are arranged inside the multi-fixed wing body 130, and a plurality of small fixed wings 1302 are arranged on the fixed wing mounting grooves 1301. The outer side of the implant auxiliary component 12 is provided with a plurality of positioning bosses which cooperate with the fixed wing mounting grooves 1301, and the positioning bosses are provided with interference protrusions for interfering with the small fixed wings 1302 to open. Through such a design, the multi-fixed wing body 130 can have more points of contact with the bone wall, which can ensure a better fixing effect. At the same time, the length of the fixed wing is significantly reduced compared with a single setting, which can reduce its deformation amount during tension.

[0098] In some implementations, such as Figure 8 As shown, the fixing device includes a multi-fixed-wing anti-slipping body 1101 and a multi-fixed-wing anti-slipping auxiliary component 1200. The multi-fixed-wing anti-slipping body 1101 is a tubular structure. The inner wall of the multi-fixed-wing anti-slipping 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 arranged as an inclined surface so that it can be used to make way for the protrusions that resist the opening of the second fixed wings 1104.

[0099] The outer side of the multi-fixed-wing anti-slipping auxiliary component 1200 is provided with a plurality of positioning bosses that cooperate with the second fixed-wing mounting groove 1102, and the positioning bosses are provided with a plurality of fixed-wing opening contact bosses 1202 for contacting the second fixed wing 1104 to open it, and the fixed-wing opening contact bosses 1202 are provided with guiding slopes 1203 and contact planes 1204. During installation, the multi-fixed-wing anti-slipping auxiliary component 1200 is inserted from the multi-fixed-wing anti-slipping body 1101 so that the fixed-wing opening contact bosses 1202 and the second fixed wing 1104 are sequentially misaligned with each other. During fixation, the multi-fixed-wing anti-slipping auxiliary component 1200 is pulled forward relative to the multi-fixed-wing anti-slipping body 1101, so that the contact position between the second fixed wing 1104 and the inner side of the second fixed wing 1104 is changed to open it and complete fixation.

[0100] Furthermore, a plurality of linearly distributed one-way anti-slip grooves 1103 are provided on the inner wall of the multi-fixed-wing anti-slip body 1101, and a one-way anti-slip boss 1201 cooperating with the one-way anti-slip grooves 1103 is provided on the outer wall of the multi-fixed-wing anti-slip auxiliary component 1200;

[0101] Furthermore, a locking boss 1205 is provided at the bottom of the positioning boss, and a locking plane 1206 is provided on the locking boss 1205. The locking boss 1205 is similar in structure to the fixed wing opening contact boss 1202, except that the length of the locking plane 1206 is smaller than the contact plane 1204, and a locking fixed wing 1105 cooperating with the locking boss 1205 is provided at the bottom of the second fixed wing mounting groove 1102, and a locking guide slope 1107 is provided on the inner side of the locking fixed wing 1105, and a locking boss 1106 is provided on the upper end of the locking guide slope 1107. In this way, when the multi-fixed wing anti-detachment auxiliary component 1200 moves into place, the lower end of the locking plane 1206 conflicts with the upper end surface of the locking guide slope 1107, thereby preventing the multi-fixed wing anti-detachment auxiliary component 1200 from returning to its position backward to ensure the firmness of the fixation.

[0102] In some embodiments, Figure 9-11 As shown, the outer side of the adjustment block body 31 is provided with threads, and the adjustment block body 31 is installed in the threaded hole 213. The adjustment block body 31 is provided with a first installation groove 3101, a second installation groove 3104, and a telescopic rod installation groove 3103 from the proximal end to the distal end, and the telescopic installation rod 35 passes through the telescopic rod installation groove 3103. The inner wall of the first installation groove 3101 is provided with a first one-way ratchet tooth 3102.

[0103] A one-way adjustment knob 32 is movably installed in the first installation groove 3101, and a third installation groove 3203 connected to the telescopic installation rod 35 is provided at the far end of the one-way adjustment knob 32. A second one-way ratchet 3205 is provided on the inner wall of the third installation groove 3203, and the telescopic installation rod 35 is provided with gear teeth that cooperate with the second one-way ratchet 3205.

[0104] A first gear 3201 is provided at the proximal end of the one-way adjustment knob 32, and the first gear 3201 cooperates with the first one-way ratchet tooth 3102. An adjustment disk connecting hole 3202 is provided on the proximal end face of the one-way adjustment knob 32, and an adjustment disk positioning groove 3204 is provided in the adjustment disk connecting hole 3202. An end face fixing ring 33 is provided at the proximal end of the adjustment block body 31 to fix the one-way adjustment knob 32, and the second one-way ratchet 3205 and the first one-way ratchet tooth 3102 are in opposite directions.

[0105] An adjusting knob 34 is installed on the adjusting disk connecting hole 3202 , and a quick-insertion boss 3401 is provided on the adjusting knob 34 . The quick-insertion boss 3401 is installed in the adjusting disk connecting hole 3202 .

[0106] Through such a design, during installation, the implant auxiliary component 12 is inserted and installed from the distal end of the auxiliary component installation hole 105, and the implant auxiliary component 12 is installed on the connecting thread 351 through the adjusting threaded hole 128; after holding the handle and inserting the insertion rod 201 into the channel, the fixed implant 1 is installed into the pre-hole on the bone, and the adjusting knob 34 is rotated. At this time, the first gear 3201 can drive the adjustment block body 31 to rotate, and the rotation direction of the second one-way ratchet 3205 is consistent with the tilt direction of the ratchet. 3025 does not drive the telescopic installation rod 35 to move, and the adjustment block body 31 applies an upward pulling force to the telescopic installation rod 35. The telescopic installation rod The mounting holes 35 and 3023 are provided with axial limit rings to ensure that the pulling force can be transmitted, and the implant auxiliary component 12 is pulled upward so that the first fixed wing 109 opens to fix the implant 1. When the implant auxiliary component 12 is installed in place; the adjustment knob 34 is rotated in the opposite direction, and the rotation direction of the one-way adjustment knob 32 is consistent with the inclination direction of the first one-way ratchet tooth 3102. The first gear 3201 does not drive the adjustment block body 31 to move, and the second one-way ratchet 3205 drives the telescopic mounting rod 35 to rotate so that 3501 is rotated out of the implant auxiliary component 12 to release the fixation, and then the insertion rod 201 is taken out from the channel to complete the installation.

[0107] Furthermore, the external threads 3501 and the adjusting block body 31 are arranged in opposite directions.
