Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a separate modular wire anchor implantation system. Background Art

[0002] Anchors are widely used for fixation of bones and soft tissues. They can be used around the shoulders, knees, hips, elbows, wrists and ankles. They use anchors and sutures to simply and effectively fix soft tissues (such as tendons and ligaments) to bones and keep them in place without loosening or excessive tension until they heal.

[0003] In the existing bone anchor implantation system, the inserter, anchor and suture are pre-assembled as one. During surgery, the inserter, anchor and suture must be used as a set, which means that the inserter is directly discarded after the surgery. In actual surgery, the number and type of anchors will be selected according to actual needs, which results in multiple inserters being discarded during one surgery and the inserters cannot be reused, which not only wastes medical resources and pollutes the environment, but is also not conducive to surgical operations.

[0034] Beneficial effects of the present invention:

[0035] The separate modular anchor implantation system with wire provided by the present invention can store the anchor and suture in a storage box, so as to realize the separate storage of the anchor and suture on the one hand, and assemble the anchor and suture into the inserter through the storage box on the other hand. When in use, only the storage box needs to be replaced, and the inserter does not need to be replaced, so as to realize the purpose of reusable inserter. Compared with the prior art, in which the anchor and the inserter are assembled one by one, and the inserter must be replaced at the same time when the anchor is replaced, the separate modular anchor implantation system with wire provided by the present invention can, firstly, reuse the inserter, reduce unnecessary medical waste, save medical resources, and be beneficial to environmental protection. Secondly, the anchor and the inserter are set separately, and the storage box is suitable for storing a variety of anchors. If it is found that the size or type of the originally planned anchor is not suitable during the operation, the material replacement after the adjustment of the surgical plan can be quickly completed by replacing the storage box. Therefore, during the operation, the anchor can be selected by replacing the storage box according to the actual needs of the operation, which not only simplifies the surgical operation, but also can adapt to complex and changeable surgical scenes. In addition, since the anchors and sutures are stored in the storage box and assembled with the insertion rod during the operation, the risk of the anchors being exposed and contaminated during the preoperative preparation process is avoided. In addition, the anchor clamping assembly in the storage box constrains the freedom of movement of the anchors throughout the process to prevent the anchors from being misplaced, detached or stuck. At the same time, the sutures in the storage box can be automatically released after implantation through the storage winding structure, and the tension is automatically adjusted during the release process. The sutures are released in an orderly manner without the risk of entanglement. The doctor does not need to manually untie the sutures or make additional adjustments, which significantly reduces the steps and surgical time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0085] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0086] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0087] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0088] Unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact.

A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0089] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0090] like Figure 1-Figure 44 As shown, an embodiment of the present invention provides a detachable modular anchor implantation system with a wire, including an inserter 1 and a storage box 2. The storage box 2 stores anchors and sutures 200. The anchors and sutures 200 can be stored in one storage box 2 or in different storage boxes 2. During the implantation operation, the inserter 1 is inserted into the storage box 2 and assembled with the anchor. After the inserter 1 is used to push the anchor out of the storage box 2, the inserter 1 is fixed to the storage box 2. After the inserter 1 and the anchor are assembled, the inserter 1 is used to implant the anchor into the bone. Then, a force is applied to the inserter 1 in a direction opposite to the implantation direction. After the inserter 1 is disconnected from the anchor, the sutures 200 are released, which simplifies the surgical operation and improves the surgical efficiency. Finally, the storage box 2 is disassembled from the inserter 1; the inserter 1 can be reused, and only the storage box 2 needs to be replaced, which solves the problems in the prior art that the anchor and the inserter 1 must be used as a set, and the inserter 1 is a disposable item, which causes waste of resources and environmental pollution. At the same time, the inserter 1 can be reused, which can save costs while ensuring structural strength, and reduce the frequency of instrument failure during surgery caused by quality problems of the inserter 1. The anchor and suture 200 are stored separately in the storage box 2 to prevent the anchor from being exposed during the preoperative preparation process and being polluted by the environment, thereby reducing the risk of surgery. In addition, the storage box 2 is relatively small in size, allowing a sufficient number and variety of storage boxes 2 to be prepared before surgery to ensure the response to emergencies during surgery.

[0091] The detachable modular wire anchor implantation system provided by the present invention is suitable for the implantation of anchors of various materials and shapes. For example, it is divided into metal anchors, polyetheretherketone anchors, absorbable anchors, full suture anchors 103 and interface anchors, etc. according to different materials; it is divided into boss anchors 101 and inner hole anchors 102 according to different shapes. In addition, the shape of the full suture anchor 103 is different from the shape of the boss anchor 101 and the shape of the inner hole anchor 102.

[0092] The inserter 1 includes a handle 11 and an insertion rod 12. A bayonet 111 is provided at one end of the handle 11. The insertion rod 12 extends into the bayonet 111 and is detachably connected to the handle 11. The bayonet 111 is used to clamp the storage box 2. The handle 11 applies force to the insertion rod 12 to insert the insertion rod 12 into the storage box 2 to push out the anchor. During the anchor implantation, the handle 11 applies force to the anchor. The head of the insertion rod 12 is provided with a plug-in portion 13, which is plugged with the anchor. Different plug-in portions 13 are adapted according to different materials and shapes of the anchor.

[0093] For example, for the full suture anchor 103 and the percussion implant anchor, a hammer is used to knock the tail of the handle 11 to knock the anchor into a predetermined position and depth, and the knocking action is stopped immediately. Then the handle 11 of the inserter 1 is held by hand and pulled out in the direction opposite to the implantation direction, and the storage box 2 releases the suture 200. When the suture 200 is completely removed from the storage box 2, the implantation is completed.

[0094] An external thread is provided at one end of the insertion rod 12 away from the plug connector, and a threaded hole 115 is provided at the bottom center of the bayonet 111. The insertion rod 12 extends into the threaded hole 115 and is screwed to the handle 11, so that the insertion rod 12 can be quickly replaced. For anchors of different materials and shapes, insertion rods 12 of different types and specifications can be replaced. The plug-in portion 13 is welded to the insertion rod 12, which has guiding and matching functions, and at the same time ensures the reliability of the connection between the plug-in portion 13 and the insertion rod 12, avoiding the medical accident of the plug-in portion 13 remaining in the bone when the inserter 1 is disconnected from the anchor when a force is applied in the direction opposite to the implantation direction.

[0095] Furthermore, a weight-reducing cavity 114 is provided at one end of the handle 11 away from the bayonet 111 , so as to reduce the overall weight of the inserter 1 .

[0096] Since the inserter 1 is a reusable surgical tool, the cost of key parts of the inserter 1 can be appropriately increased to ensure quality and improve mechanical stability. The insertion rod 12 and the plug-in portion 13 are both made of hard stainless steel machined, and the strength is much higher than the disposable stainless steel insertion rod 12 in the prior art, which can effectively avoid material failures such as thread slippage, bending, torsional deformation and fatigue fracture of the insertion rod 12. The handle 11 is moderately heavy, avoiding operational errors caused by the light weight of the plastic handle in the prior art.

[0097] Embodiment 1:

[0098] like Figure 1-Figure 9As shown, the present embodiment provides a separate modular anchor implantation system with a wire, wherein the storage box 2 stores the anchor, and the storage box 2 is provided with an inlet 214 and an outlet 215 at both ends, respectively. The insertion rod 12 can be inserted into the storage box 2 through the inlet 214, so that the plug-in portion 13 is plugged and matched with the anchor, and the anchor is pushed out from the outlet 215 to complete the assembly of the inserter 1 and the anchor. After the inserter 1 implants the anchor, moving in the direction opposite to the implantation direction can disconnect the plug-in portion 13 from the anchor.

[0099] Specifically, an insertion channel 213 is provided in the storage box 2, and the anchor is at least partially arranged corresponding to the center line of the insertion channel 213, so that the insertion rod 12 enters the storage box 2 along the insertion channel 213, and the insertion channel 213 guides the insertion rod 12. The plug-in portion 13 is plugged and fixed with the anchor, and after the insertion rod 12 pushes the anchor out of the storage box 2, the insertion rod 12 moves to the set position and the inserter 1 is fixed to the storage box 2 to avoid the storage box 2 moving on the insertion rod 12 during the implantation of the anchor through the inserter 1, which affects the implantation of the anchor.

[0100] Of course, in other embodiments, the insertion rod 12 may be directly plugged into the anchor nail after entering the storage box 2 through the inlet 214 . In this case, the insertion channel 213 may not be provided in the storage box 2 .

[0101] The inserter 1 of the detachable modular wire anchor implantation system is reusable and only requires the replacement of the storage box 2, thereby reducing costs and the probability of mechanical failure. The anchors are stored separately, and during the implantation surgery, the implants can be protected from environmental contamination during preoperative preparation, thereby reducing surgical risks. At the same time, the storage box 2 is relatively small in size, which facilitates preoperative material preparation.

[0102] The storage box 2 includes a box body 21, an anchor clamping assembly 22 and a wire storage and winding structure. The anchor clamping assembly 22 is arranged in the box body 21 and is used to clamp the anchor. After the anchor is plugged and fixed with the plug-in portion 13, under the thrust of the inserter 1, the anchor can break free from the clamping force of the anchor clamping assembly 22 and be ejected from the anchor clamping assembly 22. A threading hole is arranged on the anchor. After the suture 200 passes through the threading hole, both ends are stored in the wire storage and winding structure. When the anchor moves and is pushed out of the box body 21 under the thrust of the inserter 1, the suture 200 is pulled, and the wire storage and winding structure begins to release the suture 200 until the anchor is implanted in the bone. The inserter 1 moves in the direction opposite to the implantation direction, which can make the suture 200 slide out of the box body 21 and be completely released.

[0103] In this embodiment, the anchor and the suture 200 are stored in the same storage box 2. Of course, in other embodiments, the anchor and the suture 200 can also be stored separately.

[0104] like Figure 9-11As shown, the box body 21 includes a top shell 211 and a bottom shell 212 that are connected by snapping. The top shell 211 and the bottom shell 212 are snapped together, and the top shell 211 and the bottom shell 212 are snapped together by the hook 2111 and the hook groove. After the top shell 211 and the bottom shell 212 are snapped together, a storage space is formed therein, and an inlet 214 and an outlet 215 are respectively provided at opposite ends of the storage space. The anchor and the suture 200 are stored in the storage space, and the insertion channel 213 extends along the line connecting the inlet 214 and the outlet 215. The inlet 214 and the outlet 215 can both be connected to the insertion channel 213. The insertion rod 12 enters the storage space from the inlet 214, moves along the insertion channel 213 to be plugged with the anchor, and pushes the anchor out of the outlet 215.

[0105] Specifically, two convex strips are respectively arranged in the top shell 211 and the bottom shell 212 with their respective central symmetry lines as the center lines, and the two convex strips on the top shell 211 are butted with the two convex strips on the bottom shell 212 to form an insertion channel 213. The center line of the anchor clamping assembly 22 and the center line of the insertion channel 213 are located on the same straight line, so that the insertion rod 12 enters the insertion channel 213 through the inlet 214, and the insertion channel 213 provides guidance for the insertion rod 12. Under the guidance of the insertion channel 213, the insertion rod 12 can move to the anchor clamping assembly 22, ensuring that the plug-in portion 13 on the insertion rod 12 can be plugged and fixed with the anchor clamped in the anchor clamping assembly 22, and the anchor is ejected from the box body 21 after plugging and fixing. Two wire storage and winding structures are provided, and the two wire storage and winding structures are respectively provided on both sides of the anchor. Such a configuration facilitates the storage and release of the two ends of the suture 200 passing through the anchor through the two wire storage and winding structures.

[0106] The outer contour of the box body 21 is approximately cross-shaped, and the two wing areas of the cross are used to accommodate the wire storage and winding structure, and the head and tail areas are used to accommodate the insertion channel 213 and the anchor clamping assembly 22 respectively.

[0107] Continue to refer to Figure 1 and Figure 5 The insertion rod 12 further includes a guide boss 14 that cooperates with the insertion channel 213. The diameter of the insertion rod 12 is smaller than the inner diameter of the insertion channel 213. When the insertion rod 12 enters the box body 21, the guide boss 14 cooperates with the insertion channel 213 to provide guidance for the movement of the insertion rod 12. The guide boss 14 can be provided at one end of the insertion rod 12 close to the plug-in portion 13.

[0108] like Figure 12-14As shown, specifically, the anchor clamping assembly 22 includes an elastic member and two symmetrically arranged jaws 222, the two jaws 222 are connected by the elastic member to form a accommodating chamber 223, the inlet 214 and the outlet 215 are both connected to the accommodating chamber 223, and the anchor is stored in the accommodating chamber 223; the two jaws 222 are both slidably arranged in the storage box 2, and under the thrust of the insertion rod 12, the ends of the two jaws 222 close to the outlet 215 of the storage box 2 slide and open in a direction away from each other to push the anchor out of the storage box 2. The two clamping jaws 222 are connected by an elastic member, so that the accommodating cavity 223 formed by the two clamping jaws 222 under the action of the elastic member can clamp the anchor nail; the two clamping jaws 222 are slidably arranged in the storage box 2, so that the anchor nail can drive the two clamping jaws 222 to move away from each other under the thrust of the insertion rod 12, and the two clamping jaws 222 are opened at one end close to the outlet 215, and the insertion rod 12 pushes the anchor nail out of the accommodating cavity 223.

[0109] In this embodiment, one end of the insertion channel 213 is in communication with the inlet 214, and the other end is in communication with the accommodating chamber 223. That is, the insertion channel 213 extends from the inlet 214 to the accommodating chamber 223. When the insertion channel 213 extends from the inlet 214 to the accommodating chamber 223, the position near the outlet 215 is not constrained by the convex strip of the insertion channel 213, so that the box body 21 is easy to be removed from the inserter 1; and there is no interference with the anchor clamping assembly 22, so that the volume of the accommodating chamber 223 formed by the two clamping jaws 222 can be increased to adapt to the clamping of anchors of larger sizes.

[0110] The center line of the accommodating cavity 223 is arranged to coincide with the symmetry line of the two clamping jaws 222, that is, the anchor is placed in the accommodating cavity 223, the axis of the anchor is located on the symmetry line of the two clamping jaws 222, and the insertion rod 12 moves along the insertion channel 213 to the plug-in portion 13 to plug with the tail of the anchor. This arrangement is suitable for clamping the boss anchor 101 and the inner hole anchor 102.

[0111] The plug-in portion 13 is configured according to the shape of the anchor, including a prismatic head or an internal hole head.

[0112] For example, Fig.15 As shown, the tail of the boss anchor 101 is in the shape of a hexagonal pyramid, and the plug-in portion 13 is configured as an inner hole head, that is, a hexagonal hole that matches the hexagonal pyramid. The threading hole of the boss anchor 101 passes through the opposite sides of the hexagonal pyramid, and in order to facilitate the connection of the suture 200 passing through the threading hole with the wire storage and winding structure, the opposite sides of the hexagonal hole are connected.

[0113] like Fig.16 and Fig.17As shown, the inner hole of the inner hole anchor 102 is a hexagonal hole, which extends from the tail of the inner hole anchor 102 to the head. A cross bar 1021 is provided near the head of the inner hole anchor 102. One end of the suture 200 enters from the hexagonal hole, passes through the cross bar 1021 and then passes back. The plug-in portion 13 is provided as a prismatic head, that is, a hexagonal prism that matches the hexagonal hole. Avoidance grooves are provided on opposite sides of the hexagonal prism. Both ends of the suture 200 pass through the avoidance grooves and extend from the tail of the inner hole anchor 102.

[0114] For the formation of the accommodation cavity 223, continue to refer to Fig.12 and Fig.13 The two clamping jaws 222 are provided with cavities on the sides close to each other, and the two cavities are connected to form a receiving cavity 223. A limiting plane 2224 is provided at one end of the cavity close to the inlet 214, and a limiting inclined surface 2225 is provided at one end close to the outlet 215. The limiting plane 2224 and the limiting inclined surface 2225 jointly limit the movement of the anchor in the receiving cavity 223, ensuring that the plug-in portion 13 can be smoothly plugged with the anchor.

[0115] Furthermore, the cavity is provided in the middle of the clamping jaw 222, and semicircular holes are provided at both ends of the cavity. After the two clamping jaws 222 are butted, the semicircular holes opposite to each other in the two clamping jaws 222 are butted to form an avoidance hole for the insertion rod 12 to pass through.

[0116] A semi-annular groove 2223 is provided along the circumference of the clamping jaws 222. The semi-annular grooves 2223 of the two clamping jaws 222 are butted together to form a mounting groove, and an elastic member is provided in the mounting groove. The elastic member is provided as an elastic tape 2211 adapted to the mounting groove, and the two clamping jaws 222 are relatively fixed together by the elastic force of the elastic tape 2211 to store the anchor. At the same time, after the insertion rod 12 is plugged and fixed with the anchor, a greater thrust is applied to the anchor, and the anchor drives the two clamping jaws 222 to overcome the elastic force of the elastic tape 2211, so that the ends of the two clamping jaws 222 close to the outlet 215 move in a direction away from each other, and the end of the anchor clamping assembly 22 close to the outlet 215 is in an open state, and the anchor is pushed out of the accommodating cavity 223 and slides out of the outlet 215.

[0117] Continue to refer to Fig.10 and Fig.13 A slideway 217 is provided in the storage box 2, and a slide post 2222 is provided on the clamping jaws 222, which is slidably connected to the slideway 217. When the insertion rod 12 pushes the anchor, the anchor applies a thrust to the two clamping jaws 222. When the two clamping jaws 222 overcome the elastic force of the elastic tape 2211 and move away from each other, the slide post 222 cooperates with the slideway 217 to guide the moving direction of the two clamping jaws 222, so that after the anchor is pushed out of the accommodating cavity 223, the two clamping jaws 222 can return to their original state along the slideway 217 under the action of the elastic restoring force of the elastic tape 2211.

[0118] Slide columns 2222 are provided at both ends of the same side of each clamping jaw 222, and the slide 217 includes a first slide 2171 and a second slide 2172. The first slide 2171 is provided close to the inlet 214, and the second slide 2172 is provided close to the outlet 215. The first slide 2171 and the second slide 2172 both extend in a direction away from the clamping jaw 222 and close to the outlet 215, and the angle between the first slide 2171 and the symmetry line of the two clamping jaws 222 is smaller than the angle between the second slide 2172 and the symmetry line of the two clamping jaws 222. When the insertion rod 12 pushes the anchor, the anchor applies a force to the end of the clamp 222 near the outlet 215, and the ends of the two clamps 222 near the outlet 215 open, and the opening angle of the end near the inlet 214 is smaller than the opening angle of the end near the outlet 215. Therefore, the angle between the first slide 2171 and the symmetry line of the two clamps 222 is smaller than the angle between the second slide 2172 and the symmetry line of the two clamps 222. By providing two slides 217, the moving path of the clamp 222 can be better controlled to ensure the opening angle of the end of the clamp 222 near the outlet 215.

[0119] Specifically, continue to refer to Figure 9-11 A first slide 2171 and a second slide 2172 are provided on the top shell 211 and the bottom shell 212, and two slide posts 2222 are provided on both sides of the clamping jaw 222. In this way, the two slide posts 2222 on the side of the clamping jaw 222 close to the top shell 211 are slidably matched with the first slide 2171 and the second slide 2172 correspondingly provided on the top shell 211, and the two slide posts 2222 on the side of the clamping jaw 222 close to the bottom shell 212 are slidably matched with the first slide 2171 and the second slide 2172 correspondingly provided on the bottom shell 212, so as to ensure the stability and reliability of the two clamping jaws 222 when moving.

[0120] The wire storage and winding structures are symmetrically arranged on both sides of the anchor. After the suture 200 passes through the anchor, the two ends are respectively connected to the two wire storage and winding structures. The insertion rod 12 drives the storage box 2 to move in the direction opposite to the implantation direction, and the wire storage and winding structures can automatically release the suture 200. Before the operation, the suture 200 passes through the two ends of the anchor and is stored in the two wire storage and winding structures. After the anchor is implanted, all the sutures 200 can be released by pulling the handle 11 in the direction opposite to the implantation direction. There is no need to manually untie the suture 200, which further simplifies the surgical operation and improves the surgical efficiency.

[0121] Specifically, Figure 18-Figure 20As shown, the wire storage and winding structure includes a ratchet 23, which is rotatably arranged in the storage box 2; the ratchet 23 includes a central axis 231 and two baffles 232 arranged at both ends of the central axis 231, and the baffles 232 are provided with wire collection grooves 2321 arranged at intervals, and the suture 200 is wound around the central axis 231, and the tail end of the suture 200 is clamped into two adjacent wire collection grooves 2321. The suture 200 is wound around the central axis 231 for storage, and the tail end of the suture 200 is clamped into two adjacent wire collection grooves 2321 to prevent it from falling apart. When the suture 200 is released, under the pulling force of the anchor nail, the tail end of the suture 200 can automatically break free from the wire collection groove 2321 and be released without manual untying.

[0122] The ratchet 23 can be mounted with various types of sutures 200, such as flat tape, flat round, absorbable, barbed, coated, sandwich, etc. The ratchet 23 has enough space to accommodate sutures 200 of various sizes, such as 6-0, 4-0, 2-0, #2, #4, #6, etc.

[0123] Specifically, continue to refer to Fig.10 and Fig.11 A ratchet groove 216 is provided on the top shell 211 and the bottom shell 212. The ratchet 23 is provided in the accommodation space formed by the ratchet grooves 216 corresponding to the top shell 211 and the bottom shell 212. A sleeve 2161 rotatably matched with the central axis 231 is provided at the center of the ratchet groove 216. Both ends of the central axis 231 are respectively provided in the sleeve 2161. When the suture 200 is subjected to the pulling force of the anchor nail, the central axis 231 rotates relative to the sleeve 2161, thereby gradually releasing the suture 200.

[0124] Furthermore, if Fig. 20 As shown, a plurality of elastic pawls 233 are arranged at intervals along the circumference of the baffle 232, and an annular groove is formed between the elastic pawl 233 and the baffle 232, and a wire collection groove 2321 extending radially along the baffle 232 is arranged on the inner side of each annular groove. A boss 2331 is arranged at the end of the elastic pawl 233. During the rotation of the ratchet 23, the boss 2331 contacts the inner wall of the ratchet groove 216, which has a damping effect on the pulling out of the suture 200, ensuring that the suture 200 can be pulled out stably. The plurality of elastic pawls 233 provide a stable torque for the pulling out of the suture 200, ensuring the symmetry of the torque received by the central axis 231. In addition, during the rotation of the ratchet 23, the boss 2331 contacts the ratchet groove 216, and a clicking sound is emitted, which serves as a reminder to the medical staff that the pulling out of the suture 200 is normal.

[0125] Continue to refer to Fig.10 and Fig.11A guide damping column 218 is also provided on the peripheral side of the ratchet 23, and the suture 200 passing through the anchor bypasses the guide damping column 218 and is wound around the central axis 231. The suture 200 bypasses the guide damping column 218, and the guide damping column 218 can provide damping for the pulling and stretching action of the suture 200, reduce the low-frequency vibration generated at the interval gap between the elastic pawls 233 on the ratchet 23, and ensure the consistency of the pulling force of the suture 200 during the release process of the suture 200.

[0126] Specifically, a notch is provided in the circumferential direction of the ratchet groove 216, and a guide damping column 218 is provided outside the notch, and two guide damping columns 218 are provided, one of which is provided on one side of the notch close to the clamping jaw 222, and the other is provided on the opposite side of the notch away from the clamping jaw 222. The suture 200 passing through the anchor first bypasses the guide damping column 218 close to the clamping jaw 222, and then surrounds the guide damping column 218 away from the clamping jaw 222, and then enters the ratchet groove 216 through the notch and is wound around the central axis 231. Such a configuration allows the suture 200 to always maintain a certain tension during the release process.

[0127] like Fig.21 and Fig. 22 As shown, in order to ensure the stability of the engagement between the handle 11 and the storage box 2, a spherical groove 2121 is provided on the storage box 2, and a positioning bead 112 is provided on one side of the bayonet 111. The positioning bead 112 can cooperate with the spherical groove 2121 to fix the inserter 1 and the storage box 2. A through hole is provided on one side of the bayonet 111, and the positioning bead 112 is installed in the through hole. The positioning bead 112 is a ball plunger composed of a shell, a spring, a ball or a cylinder. The ball retracts into the shell under pressure. When the ball is opposite to the spherical groove 2121, the ball extends out under the elastic restoring force of the spring to cooperate with the spherical groove 2121, thereby fixing the storage box 2.

[0128] Specifically, the spherical grooves 2121 are arranged on the outer surface of the bottom shell 212 , and three of them are arranged at intervals along the center line of the bottom shell 212 . One positioning bead 112 is arranged. The positioning bead 112 only needs to cooperate with one of the spherical grooves 2121 to fix the storage box 2 .

[0129] The structural design of the storage box 2 provided in this embodiment converts a simple insertion action into a programmed precise mechanical match, and completes the mechanical actions of removing nails, laying out and tensioning the suture 200 during the insertion action, and cooperates with the handle 11 to achieve anchor implantation. The anchor clamping assembly 22 is configured as two symmetrical sliding jaws 222 that cooperate with the insertion channel 213. The jaws 222 clamp the anchor by means of an elastic tape 2211. After the ends of the two jaws 222 close to the inlet 214 are pushed up by the insertion rod 12, the ends close to the outlet 215 are in an open state to release the anchor. During the release process, the anchor clamping assembly 22 is constrained by the elastic tape 2211. The anchor clamping assembly 22 can be adapted to any type of anchor through simple structural improvements. The ratchet 23 and the guide damping column 218 on both sides of the anchor clamping assembly 22 can semi-automatically manage the suture 200, and release the suture 200 of a set length as required. The guide damping column 218 is used to ensure that the suture 200 released from the ratchet 23 is released in a tensioned state. The suture 200 is in an "M" shape with a ring at the tail when stored in the box body 21. The storage box 2 can realize the separate packaging of the anchor, and cooperate with the reusable inserter 1 to realize the assembly of the anchor and the inserter 1. It is small in size, allowing sufficient number and types of storage boxes 2 to be prepared before surgery to ensure the response to emergencies during surgery.

[0130] The inserter 1 provided in this embodiment is a reusable surgical tool, which can appropriately increase the cost to strengthen the strength of the structure and improve the stability of the mechanical structure. The inserter 1 can quickly replace the insertion rod 12, which is fixed to the storage box 2 through the positioning beads 112 on the handle 11. The insertion rod 12 and the plug-in part 13 are both made of hard stainless steel, which ensures the quality of the insertion rod 12 and reduces the frequency of instrument failure during surgery caused by quality problems of the inserter 1.

[0131] like Figure 23-Figure 30 As shown, the method of using the separated modular wire anchor implantation system provided in this embodiment is:

[0132] (1) Hold the handle 11 of the inserter 1 with one hand and the storage box 2 with the other hand.

[0133] (2) The insertion rod 12 enters the box body 21 from the entrance 214 of the storage box 2 and moves along the insertion channel 213. When the plug-in portion 13 moves to align with the tail of the anchor, the insertion rod 12 is continued to be pushed, and the plug-in portion 13 is plugged with the anchor. At the same time, the insertion rod 12 and the anchor push the clamping jaws 222, and the clamping jaws 222 move along the slide 217. The two clamping jaws 222 overcome the constraint of the elastic tape 2211, so that the elastic tape 2211 undergoes elastic deformation. The ends of the two clamping jaws 222 close to the exit 215 are in an open state, and the anchor is pushed out of the accommodating cavity 223. During the movement of the anchor, the suture 200 is subjected to tension, and the ratchet 23 is driven to rotate through the guide damping column 218, and the ratchet 23 begins to release the line.

[0134] (3) The insertion rod 12 continues to move, the anchor is pushed forward and slides out of the box body 21 through the outlet 215, and the clamping jaws 222 no longer slide. Under the elastic restoring force of the elastic tape 2211, the two clamping jaws 222 move toward each other until they fit the insertion rod 12 and the suture 200. The anchor drives the suture 200 to continue to move, driving the ratchet 23 to continue to rotate.

[0135] (4) The insertion rod 12 pushes the box body 21 forward, the ratchet 23 continues to rotate to release the line, and the insertion rod 12 continues to move until the box body 21 presses against the handle 11 and cannot move further. The positioning bead 112 at the bayonet 111 of the handle 11 cooperates with the spherical groove 2121 to fix the relative position of the box body 21 and the handle 11.

[0136] (5) By twisting the handle 11 to implant the anchor into the bone, the suture 200 can be released.

[0137] (6) When releasing the suture 200, the head of the suture 200 is fixed at the tail of the anchor, and the handle 11 is pulled in the direction opposite to the implantation direction. The box body 21 moves away from the anchor, and the suture 200 drives the ratchet 23 to rotate. The suture 200 is gradually released. During the release of the suture 200, the guide damping column 218 allows the suture 200 to maintain a certain tension during the pulling process.

[0138] (7) The inserter 1 continues to move in the direction opposite to the implantation direction, and the ratchet 23 continues to rotate to release the suture until the tail end of the suture 200 breaks free from the take-up groove 2321 and slides out of the box body 21, and the suture 200 is released.

[0139] (8) After the suture thread 200 is released, the box body 21 can be removed from the insertion rod 12.

[0140] After the implantation of one anchor is completed, when the next anchor is implanted, the above-mentioned inserter 1 is assembled with the next storage box 2, and the implantation of the next anchor is continued according to the above-mentioned steps, and this cycle is repeated until the implantation is completed.

[0141] Embodiment 2:

[0142] This embodiment provides a separate modular anchor implantation system with a wire, which has the same working principle and the same structure of most components as the separate modular anchor implantation system with a wire provided in the first embodiment, and the similarities are not repeated here. The main differences are: the structure of the insertion channel 213, the structure of the anchor clamping assembly 22, the wire storage and winding structure, and the fixing structure of the handle 11 and the storage box 2.

[0143] like Figure 31-Figure 36 As shown, the insertion channel 213 is set to be through-type, one end is connected to the inlet 214, and the other end is connected to the outlet 215. That is, the insertion channel 213 extends from the inlet 214 to the outlet 215. The anchor clamping assembly 22 is set on the convex strip, and the height of the convex strip between the anchor clamping assembly 22 and the inlet 214 is higher than the height of the convex strip below the anchor clamping assembly 22, so as to ensure that the center line of the anchor clamping assembly 22 and the center line of the insertion channel 213 are located on the same straight line, and the insertion rod 12 has higher stability when inserting into the box body 21 and ejecting the anchor, and there is a constraint on the rotation direction during the entire pushing process of the insertion rod 12.

[0144] Specifically, the height of the convex strip between the anchor clamping assembly 22 and the inlet 214 on the bottom shell 212 is higher than the height of the convex strip below the anchor clamping assembly 22. The convex strip on the top shell 211 extends from the inlet 214 to the anchor clamping assembly 22.

[0145] Furthermore, the connection between the inlet 214 and the insertion channel 213 is configured to be funnel-shaped, so as to facilitate smoother insertion of the insertion rod 12 .

[0146] Specifically, the two clamping jaws 222 of the anchor clamping assembly 22 are provided with a slide column 2222 on the same side of each clamping jaw 222, and the slideway 217 extends in a direction away from the clamping jaw 222 and close to the outlet 215. A slide column 2222 is provided on the same side of each clamping jaw 222, and when the clamping jaw 222 moves, a slide column 2222 is provided on each side of the clamping jaw 222, and slides with the slideways 217 on the top shell 211 and the bottom shell 212 respectively.

[0147] Furthermore, the elastic member is arranged around the slide column 2222 that is arranged opposite to each other on the two clamping jaws 222. The slide column 2222 includes a column and a slider, the outer diameter of the slider is larger than the outer diameter of the column, and the slider is slidably arranged in the slideway 217. The elastic member is an elastic rubber ring 2212, and the elastic rubber ring 2212 is clamped between the slider and the side wall of the clamping jaw 222. With such an arrangement, the clamping jaw 222 can open at a larger angle when releasing the anchor, so as to accommodate an anchor of a larger size. One elastic rubber ring 2212 can be provided, that is, one side of the two clamping jaws 222 is constrained by the elastic rubber ring 2212; two elastic rubber rings 2212 can also be provided, that is, both sides of the two clamping jaws 222 are constrained by the elastic rubber ring 2212.

[0148] The wire storage and winding structure includes a winding groove 2191 and a wire receiving hole 2192. The winding groove 2191 is symmetrically arranged on the outer periphery of the storage box 2, one of the winding grooves 2191 is provided with a wire passing hole 2193, and the wire receiving hole 2192 is symmetrically arranged on the outer periphery of the storage box 2 and communicated with the interior of the storage box 2. The suture 200 passing through the anchor passes through the wire passing hole 2193 and is wound in the relatively arranged winding groove 2191, and the tail end of the suture 200 is inserted into the relatively arranged wire receiving hole 2192. The symmetry lines of the winding groove 2191 and the wire receiving hole 2192 are both perpendicular to the center line of the insertion channel 213. With this arrangement, the suture 200 passing through the anchor passes through the wire passing hole 2193 and passes through the box body 21, is wound around the winding groove 2191 on the surface of the box body 21, and is wound around the winding groove 2191 for several turns before being wound around the wire receiving hole 2192 and fixed. The suture thread 200 on the winding groove 2191 needs to be manually untied to be released, and the suture thread 200 cannot be automatically released when the anchor is pushed out by the insertion rod 12.

[0149] Furthermore, the wire storage and winding structure also includes a wire storage groove 2194, which is disposed in the storage box 2. The suture 200 can be limited in the wire storage groove 2194. The suture 200 that passes through the anchor is led out through the wire storage groove 2194 and then passes through the wire hole 2193. The suture 200 passes through the anchor and enters the internal wire storage groove 2194. After being stacked for several turns, it is led out from the wire storage groove 2194 and passes through the wire hole 2193. This part is for storing the suture 200 inside the box body 21. The wire storage groove 2194 squeezes and fixes the suture 200 stored inside the box body 21. When the anchor is ejected, the suture 200 in the wire storage groove 2194 has a certain resistance under the squeezing force.

[0150] Specifically, the line storage groove 2194 is formed by three rectangular protrusions arranged at intervals between two vertical plates arranged opposite to each other on the bottom shell 212 or the top shell 211. There is a gap between the two vertical plates on both sides of the three rectangular protrusions to form a U-shaped groove. The upper ends of the rectangular protrusions are provided with limiting plates. The limiting plates on the rectangular protrusions in the middle are connected to the first vertical plate and are spaced from the second vertical plate. The limiting plates on the rectangular protrusions on both sides are connected to the second vertical plate and are spaced from the first vertical plate. The spacing between the limiting plates and the vertical plates is smaller than that between the limiting plates and the rectangular protrusions to compress the suture 200 and prevent the suture 200 from falling out. After the suture 200 is overlapped several times in the U-shaped groove, it is compressed by the limiting plates and led out of the U-shaped groove.

[0151] Of course, in other embodiments, the wire storage groove 2194 can also be set as a serpentine limiting groove, and the suture 200 is stored around the serpentine limiting groove.

[0152] Furthermore, the length of the suture thread 200 stored in the box body 21 is equal to the length of the insertion rod 12. When the insertion rod 12 pushes out the anchor nail to the limit position, the suture thread 200 in the wire storage groove 2194 is completely released.

[0153] Furthermore, the wire storage and winding structure also includes a tensioning member 2195, which is disposed between the anchor and the wire storage groove 2194. The suture 200 passing through the anchor enters the wire storage groove 2194 after being tensioned by the tensioning member 2195. The tensioning member 2195 includes a guide plate and a guide column. The guide plate is disposed on the outer side of the first plate and is disposed at an angle to the first plate. One end of the guide plate is connected to the first plate, and the other end is connected to the guide column. The suture 200 passing through the anchor bypasses the guide column and is guided by the guide plate into the wire storage groove 2194. The limiting plate squeezes the suture 200. When the suture 200 is released, the guide column and the guide plate can ensure that the suture 200 in the wire storage groove 2194 maintains a certain tension when released.

[0154] In the inserter 1 provided in this embodiment, a clamping member 113 is provided on one side of the bayonet 111 of the handle 11. The clamping member 113 is rotatably connected to the handle 11 and is used to cooperate with the other side wall of the bayonet 111 to clamp the storage box 2. By pressing one end of the clamping member 113, the other end of the clamping member 113 can move in a direction away from the other side wall of the bayonet 111. The clamping member is a seesaw clamping claw, which is rotatably connected to the handle 11 through a rotating shaft. A pressing portion 1132 is provided on one end of the seesaw clamping claw. By pressing the pressing portion 1132, the other end of the seesaw clamping claw moves in a direction away from the other side wall of the bayonet 111, thereby releasing the storage box 2 and removing the storage box 2.

[0155] Specifically, the storage box 2 is provided with a plurality of slots 2122, and the other end of the clamping member 113 is provided with a plurality of protrusions 1131, which are engaged with the slots 2122. The protrusions 1131 are provided with trapezoidal teeth, which greatly increase the connection strength between the storage box 2 and the handle 11, and prevent the storage box 2 from accidentally falling off. After use, the storage box 2 can be disassembled by pressing the pressing portion 1132.

[0156] Embodiment three:

[0157] This embodiment provides a separate modular anchor implantation system with a wire, which has the same working principle and most component structures as the separate modular anchor implantation system provided in the first embodiment, and the similarities are not repeated here. The main differences are: the structure of the plug-in portion 13 and the structure of the anchor clamping assembly 22.

[0158] like Figure 37-Figure 44 As shown, in the separated modular anchor implantation system provided by the present embodiment, the full suture anchor 103 is a flexible anchor, the middle portion of which is set to be flat, and the full suture anchor 103 is placed horizontally when stored, and the plug-in portion 13 includes a plug-in rod 131 and a fork-shaped head 1311, and the fork-shaped head 1311 is arranged at one end of the plug-in rod 131 away from the insertion rod 12. After the fork-shaped head 1311 clamps the flat structure in the middle of the full suture anchor 103, a force is applied to the full suture anchor 103 through the insertion rod 12, and the full suture anchor 103 is deformed and becomes V-shaped when pushed out of the storage box 2. According to the structure of the full suture anchor 103, the structure of the plug-in portion 13 and the structure of the anchor clamping assembly 22 are improved.

[0159] In the anchor clamping assembly 22 provided in this embodiment, the center line of the accommodating cavity 223 is perpendicularly arranged to the symmetry line of the two clamping jaws 222, and the two clamping jaws 222 are connected to form a through hole 224 whose center line coincides with the symmetry line of the two clamping jaws 222, and the through hole 224 is used for the insertion rod 12 to pass through. That is, the structure of the clamping jaw 222 is changed according to the structure of the full suture anchor 103, so that the storage box 2 is also suitable for storing the full suture anchor 103.

[0160] Furthermore, in order to facilitate the horizontal full suture anchor 103 to be more easily ejected from the anchor clamping assembly 22 by the insertion rod 12, one end of the clamping jaw 222 close to the outlet 215 of the storage box 2 is set as an opening 2221, and the accommodating cavity 223 is connected to the opening 2221.

[0161] like Figure 39-Figure 43As shown, the full suture anchor 103 is placed horizontally in the accommodating cavity 223, and the suture 200 extends from both ends of the full suture anchor 103 and is respectively connected to the wire storage and winding structures on both sides. The insertion rod 12 enters the box body 21 from the through hole 224, moves to the fork-shaped head 1311 and clamps with the flat structure in the middle of the full suture anchor 103, and continues to move. The middle part of the full suture anchor 103 is deformed into a protruding shape, and the clamping jaws 222 gradually open under the extrusion of the protruding shape. The insertion rod 12 continues to move, and the full suture anchor 103 continues to move and is squeezed into an approximately V-shape. After the clamping jaws 222 open to a sufficient angle so that the full suture anchor 103 can pass through, the angle is no longer further expanded under the action of the elastic tape 2211, and the ratchet 23 is pulled by the suture 200 and starts to rotate. The insertion rod 12 continues to move, and the full suture anchor 103 can completely break away from the opening 2221 and be ejected from the box body 21.

[0162] When implanting the full suture anchor 103, it is necessary to knock the tail of the handle 11 to knock the full suture anchor 103 into the predetermined position and depth, then the handle 11 can be held to pull out the insertion rod 12 in the direction opposite to the implantation direction, and the ratchet 23 rotates to release the suture 200. After the suture 200 is released, the implantation is completed, and the box body 21 can be removed from the insertion rod 12.

[0163] like Fig.44 As shown, the plug rod 131 is also provided with a stress release platform 1312 and a marking line 1313, and the marking line 1313 is provided between the stress release platform 1312 and the insertion rod 12. The function of the stress release platform 1312 is to reduce the extrusion contact stress during the percussion implantation. The marking line 1313 indicates the implantation depth during the operation. The diameter of the plug rod 131 is smaller than the diameter of the insertion rod 12, so as to reduce the interface interference between the bone-plug rod 131-anchor caused by the percussion implantation.

[0164] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
