Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an external row anchor implant system. Background Art

[0002] In the surgical fields such as orthopedics and sports medicine, external row anchors play a key role in the repair of soft tissues such as tendons and ligaments. Different from internal row anchors, external row anchors do not carry threads by themselves. During the operation, the sutures required for the operation need to be introduced first, and then they are implanted on the side of the bone to achieve suture fixation.

[0003] However, the existing technology has obvious deficiencies. In the surgical preparation stage, the assembly process of the implantor, the external row anchor and the suture is extremely cumbersome. Medical staff need to spend a lot of time and energy on delicate operations. The complex assembly process increases the operation difficulty, reduces the surgical efficiency, and is not conducive to the smooth progress of the operation.

[0004] Based on this, there is an urgent need for an external row anchor implant system to solve the above-mentioned existing problems. Summary of the Invention

A limiting groove communicating with the guiding hole is provided on the side wall of the guiding hole. The limiting flap is hinged in the limiting groove. The limiting flap is provided with a limiting protrusion. The outer rod includes a pushing station and an avoiding station. When the outer rod slides to the avoiding station, the fastening screw is located at one end of the kidney-shaped hole close to the external row anchor, and the limiting flap rotates so that the limiting protrusion can pass through the other end of the kidney-shaped hole away from the external row anchor; when the outer rod slides to the pushing station, the fastening screw is located at the other end of the kidney-shaped hole away from the external row anchor.

[0015] As a preferred technical solution of an external row anchor implant system, the limiting assembly includes a limiting member. A limiting hole is provided on the side wall of the limiting groove. The limiting member is connected to the limiting flap and is slidably connected in the limiting hole.

[0016] As a preferred technical solution for an external row anchor implantation system, the limiting member is a spring plunger, and two first positioning grooves are arranged at intervals on the side walls opposite to the limiting hole. When the limiting protrusion is inserted into the waist-shaped hole, the end of the spring plunger facing away from the limiting hole is elastically embedded in one of the first positioning grooves. When the limiting protrusion is separated from the waist-shaped hole, the end of the spring plunger facing away from the limiting hole is elastically embedded in another of the first positioning grooves.

[0017] As a preferred technical solution for an outer row anchor implantation system, the end of the outer rod away from the outer row anchor extends out of the guide hole and is provided with an end cover.

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides an outer row anchor implantation system, wherein the outer row anchors are stored in the receiving hole of the anchor box, and the elastic crimping assembly elastically crimps the outer row anchors so that the outer row anchors are stably installed in the receiving hole. When the implanter needs to be assembled with the outer row anchors, the push assembly of the implanter sequentially extends into one end of the receiving hole and the inner hole of the outer row anchors and pushes the outer row anchors. During the extension of the push assembly, the receiving hole provides a guide so that the outer row anchors are installed on the push assembly. The outer row anchors are continuously pushed, and the outer row anchors overcome the elastic crimping force of the elastic crimping assembly, so that the outer row anchors are detached through the other end of the receiving hole, and the push assembly is moved out through the opening, and the assembly of the outer row anchors and the implanter is now completed.

[0021] When the sutures of the inner row of anchors need to be assembled with the outer row of anchors, the sutures only need to be passed through the wire pull ring, and then the wire pull box pulls the wire pull ring, which drives the sutures to pass through the wire holes of the outer row of anchors, thus realizing the assembly of the sutures and the outer row of anchors, and then the outer row of anchors are implanted into the human bone canal. Since the wire pull ring is larger than the wire hole, the difficulty of suture assembly is reduced.

[0022] The invention realizes the storage of the outer row of anchors, reduces the difficulty of assembly between the outer row of anchors and the implanter and between the outer row of anchors and the pull wire ring, and improves surgical efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Such as Figure 1 And Figure 2As shown in the figure, this embodiment provides an external row anchor implant system, which includes an anchor box 1 and an implantor 2. Specifically, the anchor box 1 includes a housing assembly 11, an elastic crimping assembly 12, and a wire pulling box 13. The housing assembly 11 is provided with a receiving hole 113 for receiving the external row anchor 100. The elastic crimping assembly 12 is arranged on the side wall of the receiving hole 113 and is used for crimping the external row anchor 100. The external row anchor 100 includes a nail head 101, and the nail head 101 is provided with a wire hole 1011. The wire pulling box 13 is connected to the housing assembly 11, and the wire pulling box 13 is provided with a wire pulling ring 131, and the wire pulling ring 131 passes through the wire hole 1011. The implantor 2 includes a handle 21 and a pushing assembly 22. One end of the pushing assembly 22 is connected to the handle 21, and the other end of the pushing assembly 22 can sequentially extend into one end of the receiving hole 113 and the inner hole of the external row anchor 100 and push the external row anchor 100, so that the external row anchor 100 is separated from the other end of the receiving hole 113. An opening 115 for the movement of the pushing assembly 22 is provided on the side wall of the receiving hole 113.

[0041] Among them, the external row anchor 100 is stored in the receiving hole 113 of the anchor box 1, and the elastic crimping assembly 12 elastically crimps the external row anchor 100 so that the external row anchor 100 is stably installed in the receiving hole 113. The wire pulling ring 131 of the wire pulling box 13 is pre-passed through the wire hole 1011 and is in clearance fit with the anchor box 1. When the implantor 2 needs to be assembled with the external row anchor 100, the pushing assembly 22 of the implantor 2 sequentially extends into one end of the receiving hole 113 and the inner hole of the external row anchor 100 and pushes the external row anchor 100. During the process of the pushing assembly 22 extending in, the receiving hole 113 provides guidance so that the external row anchor 100 is installed on the pushing assembly 22. Continuing to push the external row anchor 100, the external row anchor 100 overcomes the elastic crimping force of the elastic crimping assembly 12, so that the external row anchor 100 is separated from the other end of the receiving hole 113, and the pushing assembly 22 moves out through the opening 115. At this time, the assembly of the external row anchor 100 and the implantor 2 is realized, and then the external row anchor 100 is implanted into the human bone canal. When the suture 200 of the internal row anchor needs to be assembled with the external row anchor 100, only the suture 200 needs to be passed through the wire pulling ring 131, and then the wire pulling box 13 pulls the wire pulling ring 131, and the wire pulling ring 131 drives the suture 200 to pass through the wire hole 1011 of the external row anchor 100, realizing the assembly of the suture 200 and the external row anchor 100. Since the size of the wire pulling ring 131 is larger than that of the wire hole 1011, the assembly difficulty of the suture 200 is reduced. This embodiment realizes the storage of the external row anchor 100, reduces the assembly difficulty between the external row anchor 100 and the implantor 2 and between the external row anchor 100 and the wire pulling ring 131, and improves the surgical efficiency.

[0042] During surgery, for different surgeries, two outer row anchor screws 100 are often required to cooperate with each other. To meet the actual surgical needs, preferably, the receiving holes 113, the elastic crimping components 12, and the wire drawing boxes 13 are all at least two and correspond one by one. In this embodiment, the anchor screw box 1 can store two outer row anchor screws 100. The anchor screw box 1 not only supports the independent storage of the two outer row anchor screws 100, but also can quickly and sequentially complete the assembly and use of the two outer row anchor screws 100 and the implantor 2 during the surgery.

[0043] In this embodiment, as Figure 2 and Figure 3 shown, the housing assembly 11 includes an upper shell 111 and a lower shell 112. The upper shell 111 is detachably connected to the lower shell 112, specifically, it can be connected by screws or snap connection. A receiving hole 113 and a mounting groove 114 for mounting the wire drawing box 13 are formed between the upper shell 111 and the lower shell 112. In this embodiment, the mounting groove 114 is arranged at the corner of the housing assembly 11, and the wire drawing box 13 is embedded in the mounting groove 114. The outer row anchor screw 100 and the wire drawing box 13 can be detached from the anchor screw box 1 simultaneously.

[0044] In this embodiment, the elastic crimping component 12 includes an elastic member 121 and a crimping block 122. A groove is provided on the side wall of the receiving hole 113. One end of the elastic member 121 is connected to the bottom of the groove, and the other end is connected to the crimping block 122. The elastic force of the elastic member 121 can drive the crimping block 122 to crimp on the outer row anchor screw 100. In this embodiment, the groove is arranged on the upper shell 111, and the crimping block 122 can reciprocate in the groove under the elastic force of the elastic member 121. A first semi-cylindrical cavity is provided on the side wall of the crimping block 122 that crimps on the outer row anchor screw 100, and a second semi-cylindrical cavity is provided on the lower shell 112. The outer row anchor screw 100 is wrapped between the first semi-cylindrical cavity and the second semi-cylindrical cavity. In this embodiment, the elastic member 121 is a spring, and the crimping block 122 is elastically abutted by two springs. Two second positioning grooves 1221 are provided on the crimping block 122, and one end of the spring is embedded in the second positioning groove 1221 to improve the stability.

[0045] In this embodiment, the spring force of the elastic member 121 controls the movement of the crimping block 122 in the groove of the upper shell 111, forming an adaptive clamping and releasing mechanism, ensuring that the outer row anchor screw 100 is firmly clamped when not in use, avoiding the detachment of the outer row anchor screw 100 during transportation or operation, and being able to be smoothly released when the implantor 2 ejects, improving the fluency of the surgical operation; at the same time, the implantor 2 ejects the outer row anchor screw 100 after being adapted through the receiving hole 113, and then withdraws from the opening 115 on one side of the receiving hole 113, forming an efficient seamless docking and separation system, significantly improving the fluency of the surgical operation, simplifying the surgical steps, and improving the surgical efficiency.

[0046] Furthermore, as Figure 1 、Figure 4 and Figure 5 As shown in Figure 5 , the pushing component 22 includes an inner rod 221. One end of the inner rod 221 is connected to the handle 21, and the other end of the inner rod 221 can extend into the outer row of anchor nails 100. A stop portion 2211 is provided on the outer wall of the inner rod 221, and the stop portion 2211 is used to stop the nail body 102 of the outer row of anchor nails 100. In this embodiment, the nail body 102 and the nail head 101 of the outer row of anchor nails 100 are of a split structure. During the pushing process of the inner rod 221, the inner rod 221 first passes through the inner hole of the nail body 102, and then has an interference fit with the inner hole of the nail head 101. As the inner rod 221 continues to move, the nail body 102 of the outer row of anchor nails 100 contacts the stop portion 2211. As the inner rod 221 continues to move, the outer row of anchor nails 100 moves along the pushing direction together with the inner rod 221 until the outer row of anchor nails 100 disengages from the receiving hole 113. In this embodiment, the stop portion 2211 is conical, and the outer diameter of the stop portion 2211 gradually increases in the direction away from the outer row of anchor nails 100.

[0047] Preferably, the pushing component 22 further includes an outer rod 222 and a fastening screw 223. The handle 21 is provided with a guiding hole 211. The outer rod 222 is slidably connected to the guiding hole 211. The inner rod 221 is installed inside the outer rod 222. A kidney-shaped hole 2221 is provided on the side wall of the outer rod 222. Opposite side walls of the guiding hole 211 are respectively provided with a first through hole 212 and a first threaded hole 213. The inner rod 221 is provided with a second through hole 2212 coaxial with the first through hole 212. The fastening screw 223 sequentially passes through the first through hole 212, the kidney-shaped hole 2221, and the second through hole 2212 and is threadedly connected to the first threaded hole 213. The outer rod 222 is used to push the tail end of the outer row of anchor nails 100. Among them, the fastening screw 223 realizes the connection between the inner rod 221 and the handle 21, and the fastening screw 223 and the kidney-shaped hole 2221 move relative to each other, and the fastening screw 223 does not interfere with the sliding of the outer rod 222 in the guiding hole 211. During the implantation operation, the outer rod 222 moves forward relative to the handle 21, and the distal end of the outer rod 222 contacts and pushes the tail end of the outer row of anchor nails 100, so that the nail body 102, the nail head 101 and the suture 200 of the outer row of anchor nails 100 are implanted into the human tissue together. After the nail body 102, the nail head 101 and the suture 200 are implanted, the implantor 2 is withdrawn, and the second outer row of anchor nails 100 is implanted. In this embodiment, there are two fastening screws 223 and two kidney-shaped holes 2221, and the two kidney-shaped holes 2221 are arranged at intervals along the axial direction of the outer rod 222.

[0048] Preferably, the implantor 2 further includes a limiting component 23. The limiting component 23 includes a limiting flap 231. A limiting groove 214 communicating with the guiding hole 211 is provided on the side wall of the guiding hole 211. The limiting flap 231 is hinged in the limiting groove 214. In this embodiment, the limiting flap 231 is hinge-connected to the limiting groove 214 of the handle 21 through a cylindrical pin. The limiting flap 231 is provided with a limiting protrusion 2311. The outer rod 222 includes a pushing station and an avoiding station. When the outer rod 222 slides to the avoiding station, the fastening screw 223 is located at one end of the kidney-shaped hole 2221 close to the outer row of anchor nails 100. The limiting flap 231 rotates so that the limiting protrusion 2311 can pass through the end of the kidney-shaped hole 2221 away from the outer row of anchor nails 100. When the outer rod 222 slides to the pushing station, the fastening screw 223 is located at the end of the kidney-shaped hole 2221 away from the outer row of anchor nails 100. Before the implantation surgery, the outer rod 222 first slides to the avoiding station, the fastening screw 223 is located at one end of the kidney-shaped hole 2221 close to the outer row of anchor nails 100, and the limiting flap 231 rotates so that the limiting protrusion 2311 passes through the end of the kidney-shaped hole 2221 away from the outer row of anchor nails 100. Both ends of the kidney-shaped hole 2221 are limited by the limiting protrusion 2311 and the fastening screw 223 respectively to prevent the outer rod 222 from moving relative to the handle 21. During the implantation surgery, the limiting flap 231 rotates so that the limiting protrusion 2311 disengages from the end of the kidney-shaped hole 2221 away from the outer row of anchor nails 100, and then the outer rod 222 moves relative to the handle 21 in the direction close to the outer row of anchor nails 100 until the fastening screw 223 is located at the end of the kidney-shaped hole 2221 away from the outer row of anchor nails 100. At this time, the implantation of the outer row of anchor nails 100 is completed. The limiting mechanism of the limiting flap 231 in this embodiment avoids excessive movement of the outer rod 222 caused by misoperation and reduces the surgical risk. In this embodiment, the limiting flap 231 is located at one end of the handle 21 away from the outer row of anchor nails 100 and cooperates with the kidney-shaped hole 2221 on the side away from the outer row of anchor nails 100. In this embodiment, a hinge post 233 is provided on the side wall of the limiting groove 214, and the limiting flap 231 is hinged to the hinge post 233.

[0049] Preferably, the limiting component 23 includes a limiting member 232. A limiting hole 215 is provided on the side wall of the limiting groove 214. The limiting member 232 is connected to the limiting flap 231 and is slidably connected in the limiting hole 215. The limiting member 232 slides in the limiting hole 215 to limit the maximum displacement of the rotation of the limiting flap 231, realize the precise rotation of the limiting flap 231 within a small angle range, thereby precisely controlling the axial movement of the outer rod 222, and improving the accuracy and convenience of the surgical operation.

[0050] Further preferably, the limiting member 232 is a spring plunger, and two first positioning grooves 216 are arranged at intervals on the side wall opposite to the limiting hole 215. When the limiting protrusion 2311 is inserted into the waist-shaped hole 2221, one end of the spring plunger away from the limiting hole 215 is elastically embedded in one first positioning groove 216, and when the limiting protrusion 2311 is separated from the waist-shaped hole 2221, one end of the spring plunger away from the limiting hole 215 is elastically embedded in the other first positioning groove 216. When the limiting protrusion 2311 is inserted into the waist-shaped hole 2221, one end of the spring plunger away from the limiting hole 215 is elastically embedded in one first positioning groove 216, and when the limiting protrusion 2311 is separated from the waist-shaped hole 2221, one end of the spring plunger away from the limiting hole 215 is elastically embedded in the other first positioning groove 216. The spring plunger cooperates with the two first positioning grooves 216, and the two first positioning grooves 216 can limit the two positions of the rotation of the limit paddle 231. The spring plunger can also be separated from the first positioning groove 216 under the action of external force, so as to realize the rapid unlocking and locking of the outer rod 222, which significantly improves the convenience and safety of operation.

[0051] Preferably, one end of the outer rod 222 away from the outer row anchor 100 extends out of the guide hole 211 and is provided with an end cap 224. When the outer rod 222 slides to the abutting position, the end cap 224 can abut against the end surface of the guide hole 211 away from the outer row anchor 100. The end cap 224 can prevent impurities from entering the inner rod 221 and the outer rod 222, and when the outer rod 222 is driven to move forward relative to the handle 21, the end cap 224 can be knocked until the end cap 224 abuts against the end surface of the guide hole 211 away from the outer row anchor 100.

[0052] This embodiment also provides the working steps of the external row anchor implantation system, which are as follows:

[0053] Step 1: The inner rod 221 of the implanter 2 sequentially extends into one end of the accommodating hole 113 and the inner hole of the outer row anchor 100 and pushes the outer row anchor 100, so that the outer row anchor 100 is disengaged through the other end of the accommodating hole 113, and the pushing assembly 22 is disengaged through the opening 115, thereby realizing the assembly of the implanter 2 and the outer row anchor 100.
