In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0055] The embodiment of the present invention discloses an implanting device and an implanting system for external row anchor nails.

[0056] Refer to Figures 1 to 3The implantation device for the outer row anchor comprises a snap-fit ​​head 1, an implant rod 2 and a handle 21. The snap-fit ​​head 1 has a connection channel; the implant rod 2 is arranged in the connection channel, and one end of the implant rod 2 passing through the connection channel can be inserted into the anchor box 3 and assembled with the outer row anchor 4 in the anchor box 3, and then the outer row anchor 4 with the suture 5 is pushed out of the anchor box 3, and then the outer row anchor 4 with the suture 5 is implanted into the designated part; the handle 21 is arranged at the other end of the implant rod 2 and is used to drive the implant rod 2 to rotate, the implant rod 2 has a threaded section 22, and the snap-fit ​​head 1 is provided with an abutment 14, and the abutment 14 is engaged in the thread of the threaded section 22, so as to drive the implant rod 2 to move axially relative to the snap-fit ​​head 1 when the implant rod 2 rotates to implant the outer row anchor 4 into the designated part.

[0057] Specifically, the engaging head 1 is block-shaped, with a through hole in the middle thereof as a connecting passage, and the implant rod 2 is long and strip-shaped, with one end thereof passing through the connecting passage and plugged into the anchor box 3, in which the outer row of anchors 4 are pre-stored, and the end of the implant rod 2 inserted into the anchor box 3 is plugged into the outer row of anchors 4 and fixedly assembled with the outer row of anchors 4. A handle 21 is provided at one end of the implant rod 2 away from the anchor box 3, and the handle 21 can be fixedly connected with the implant rod 2 by a detachable connection such as a snap connection or a threaded connection, or can be fixedly connected by a non-detachable connection such as welding, bonding or integral molding.

[0058] A threaded section 22 is provided at the portion of the implant rod 2 located in the connection channel of the snap-fit ​​head 1. The thread in the threaded section 22 may be a trapezoid or a triangle, and a guide groove is formed between two adjacent threads. An abutment portion 14 is provided on the snap-fit ​​head 1, and at least a portion of the abutment portion 14 can extend into the connection channel and be inserted into the guide groove, that is, a snap-fit ​​fit is formed with the thread. In the present embodiment, the abutment portion 14 is a screw, and a threaded hole connected to the connection channel is provided through the snap-fit ​​head 1. The screw is threadedly connected in the threaded hole and the lower end of the screw is inserted into the above-mentioned guide groove. In other embodiments, the abutment portion 14 may be a clamping rod, and in this case, only a through hole needs to be provided on the snap-fit ​​head 1 so that one end of the clamping rod can be inserted into the connection channel, and then a block or other structure is used to close the through hole to lock the clamping rod. The specific implementation method of the abutment portion 14 is not limited by the present invention, and it can form a snap-fit ​​fit with the thread of the threaded section 22.

[0059] During assembly, one end of the implant rod 2 is passed through the connection channel, and the end of the implant rod 2 passing through the connection channel is inserted into the anchor box 3, so that the implant rod 2 is inserted into the outer row of anchor nails 4 and forms a fixed insertion connection with the outer row of anchor nails 4. At this time, the outer row of anchor nails 4 can be threaded, so that the suture 5 passes through the outer row of anchor nails 4. Continuing to push the implant rod 2, the implant rod 2 squeezes the outer row of anchor nails 4 until the outer row of anchor nails 4 is pushed out of the anchor box 3. During implantation, the grip handle 21 drives the implant rod 2 to rotate, and the abutting portion 14 abuts tightly against the thread in the threaded section 22, so that the implant rod 2 moves axially relative to the engaging head 1 during rotation, thereby gradually implanting the outer row of anchor nails 4 into the designated position. After implantation is completed, the implant rod 2 is separated from the outer row of anchor nails 4, and then the anchor box 3 is pulled out from the implant rod 2. The anchor box 3 can be discarded, while the implant device can be recycled. Therefore, when using this implant device for the outer row of anchor nails, on the one hand, the outer row of anchor nails 4 is stored in the anchor box 3, and the implant rod 2 and the anchor box 3 are set in the form of a shell plug-in assembly, so that the implant rod 2 and the anchor box 3 form a detachable connection. After the outer row of anchor nails 4 is implanted, the implant device can be recycled to improve the utilization rate of the implant device and reduce the waste of medical resources. On the other hand, during the implantation of the outer row of anchor nails 4, a dynamic spiral coupling is formed through the thread cooperation between the abutting portion 14 and the threaded section 22. This can not only avoid the problems of easy jamming and wear in the traditional threaded connection during transmission, but also reduce the contact area of the threads, reduce the vibration and noise during transmission, and improve the accuracy of axial displacement control, thereby improving the stability and reliability of the implantation process and facilitating the highly precise implantation of the outer row of anchor nails 4 during the operation.

[0060] Optionally, a plurality of abutting portions 14 are arranged at intervals.

[0061] Specifically, a plurality of abutting portions 14 can be distributed along the extension direction of the connection channel, and the plurality of abutting portions 14 can be symmetrically arranged to improve the mechanical balance during transmission, thereby further improving the smoothness and durability of the implant rod 2 during rotation.

[0062] Referring to Figures 3 to 6 , optionally, the end of the implant rod 2 away from the handle 21 has a connection section 23 that can be inserted into the outer row of anchor nails 4. The head end of the connection section 23 has a connection protrusion 24, and the connection protrusion 24 is used to abut tightly against the inner wall of the nail head of the outer row of anchor nails 4.

[0063] Specifically, the head end of the connection section 23 can be stepped, and the connection protrusion 24 is arranged on the surface of its small diameter. The connection protrusion 24 can have an inclined surface, an arc surface, a spherical surface, etc., and it can abut tightly against the inner wall of the nail head when inserted into the nail head of the outer row of anchor nails 4 to form an interference fit.

[0064] Optionally, the connecting projection 24 is arc-shaped, and the inner side of the head of the outer row of anchor pins 4 has a stepped hole 41 that abuts against the connecting projection 24.

[0065] Specifically, a stepped hole 41 is provided on the inner side of the head of the outer row of anchor pins 4, and the aperture decreases along the insertion direction of the connecting section 23. The arc surface of the connecting projection 24 can abut against the hole wall of the small-diameter hole in the stepped hole 41, thereby forming an interference fit.

[0066] The outer row of anchor pins 4 and the connecting section 23 are fixed by forming an interference fit between the connecting section 23 and the outer row of anchor pins 4, so that a radial pressing is formed between the connecting projection 24 and the outer row of anchor pins 4, enabling the head of the outer row of anchor pins 4 to rotate synchronously smoothly when the implant rod 2 rotates. Moreover, compared with screw connection, the interference fit formed by the radial extrusion of the arc surface can increase the contact area between the two, thereby achieving more stable force transmission and higher connection strength to further ensure the high-precision implantation of the outer row of anchor pins 4.

[0067] Optionally, the cross-section of the connecting section 23 is polygonal and the side wall of the connecting section 23 fits against the inner side wall of the outer row of anchor pins 4.

[0068] Specifically, the cross-section of the connecting section 23 can be hexagonal to match the body of the outer row of anchor pins 4. The specific shape of the connecting section 23 can be designed according to the body of the outer row of anchor pins 4, and the present invention does not limit this. By setting the cross-section of the connecting section 23 to be polygonal, multiple surface contacts are formed between the connecting section 23 and the body of the outer row of anchor pins 4 to ensure that the outer row of anchor pins 4 can rotate synchronously with the implant rod 2.

[0069] Refer to Figure 2 , optionally, the implant rod 2 is inserted into the handle 21, and the handle 21 is provided with a locking portion 211 that abuts against one end of the implant rod 2 inserted into the handle 21.

[0070] Specifically, a blind hole is provided at the front end of the handle 21, and the implant rod 2 is inserted into the blind hole. A locking portion 211 is inserted into the side wall of the handle 21, and the locking portion 211 can extend into the blind hole and abut against the side wall of the implant rod 2, thereby fixing the implant rod 2 in the blind hole. The locking portion 211 can be a screw, and the handle 21 is correspondingly provided with a threaded hole. The locking portion 211 can also be an insertion rod. In this case, the handle 21 only needs to be correspondingly provided with a through hole communicating with the blind hole, and at the same time, a clamping hole can also be correspondingly provided on the implant rod 2 for the insertion rod to insert. The specific structure of the locking portion 211 can be designed according to the actual installation difficulty, and the present invention does not limit this.

[0071] By setting the handle 21 and the implant rod 2 to be detachably connected, it is possible to facilitate the replacement of any structure, thereby improving the utilization rate of the structure, reducing the waste of medical resources, and at the same time, the fixation of the handle 21 and the implant rod 2 can be achieved through simple plug-in cooperation, making the installation process simple and easy to operate.

[0072] Referring to Figure 2 , Figure 3 and Figure 7 , optionally, the implanting device for the outer row of anchor screws further includes a protective sleeve 15. The protective sleeve 15 is sleeved on the threaded section 22 of the implant rod 2, and the abutting portion 14 passes through the protective sleeve 15 and is threadedly engaged with the thread of the threaded section 22.

[0073] Specifically, one end of the protective sleeve 15 is fixedly connected to the engaging head 1. The two can be of an integral structure, or can be fixed together by bonding or welding. The other end of the protective sleeve 15 passes through the connection channel, and the implant rod 2 is located inside the protective sleeve 15. The inner diameter of the protective sleeve 15 is larger than the diameter of the implant rod 2, so as to form a moving gap between the protective sleeve 15 and the implant rod 2 to ensure that the implant rod 2 can rotate smoothly. A through hole is provided at the position of the protective sleeve 15 corresponding to the abutting portion 14 for the abutting portion 14 to be inserted. The protective sleeve 15 covers the entire threaded section 22, and the protective sleeve 15 extends along the axial direction of the implant rod 2 to the side close to the connecting section 23, and the protective sleeve 15 can also be inserted into the anchor screw box 3.

[0074] By providing the protective sleeve 15, on the one hand, it can play a guiding role during the insertion process of the implant rod 2 to ensure that the implant rod 2 does not deviate, and on the other hand, it can also play a protective role for the relatively long implant rod 2 to prevent the implant rod 2 from being damaged.

[0075] Optionally, the engaging head 1 has a fixing portion 11, and the fixing portion 11 abuts against the outer side wall of the protective sleeve 15.

[0076] Specifically, the protective sleeve 15 is in plug-in cooperation with the connection channel. A fixing portion 11 is provided on the engaging head 1, and a part of the fixing portion 11 extends into the connection channel. A fixing groove is provided on the outer side wall of the protective sleeve 15, and the fixing portion 11 can be tightly abutted against the bottom wall of the fixing groove, thereby fixing the protective sleeve 15 on the engaging head 1. In this embodiment, the fixing portion 11 is a screw. In other embodiments, the fixing portion 11 can also be a plugging rod or other structures as long as it can fix the protective sleeve 15.

[0077] By setting the protective sleeve 15 and the engaging head 1 to be detachably connected, the protective sleeve 15 and the engaging head 1 can be separated to facilitate the replacement of any one of them, thereby further saving medical resources.

[0078] Optionally, the protective sleeve 15 has a guiding block 151. The anchor box 3 has a plugging channel 31 for inserting the protective sleeve 15, and the plugging channel 31 has a guiding groove 32 for the guiding block 151 to slide in.

[0079] Specifically, a plugging channel 31 is formed in the anchor box 3. The plugging channel 31 communicates with the outer row of anchor nails 4. A guiding groove 32 is provided on the side wall of the plugging channel 31, and the guiding groove 32 extends along the length direction of the plugging channel 31. The guiding block 151 is adapted to be located in the guiding groove 32. In this embodiment, a cuboid-shaped guiding block 151 is provided on each of the upper and lower sides of the protective sleeve 15. Correspondingly, a guiding groove 32 is provided on each of the upper and lower sides of the plugging channel 31.

[0080] By providing the guiding block 151 and the guiding groove 32, when being plugged and matched with the anchor box 3, the guiding block 151 and the guiding groove 32 can cooperate to accurately define the moving direction, so as to ensure that the implanting rod 2 is accurately inserted into the outer row of anchor nails 4.

[0081] Optionally, the engaging head 1 has a receiving cavity 12 for receiving the anchor box 3. A locking member 13 is provided on the cavity wall of the receiving cavity 12, and the locking member 13 is used for engaging with the anchor box 3 to lock the anchor box 3 in the receiving cavity 12.

[0082] Specifically, one end of the engaging head 1 away from the handle 21 is U-shaped to form the receiving cavity 12. A locking member 13 is provided on the cavity wall of the receiving cavity 12. The locking member 13 has a certain elasticity, and it can contract when the anchor box 3 is inserted, and release to form a snap connection with the anchor box 3 after the anchor box 3 is inserted. In this embodiment, the locking member 13 adopts a spring plunger. A snap hole for snap connection with the anchor box 3 is formed on the side wall of the anchor box 3. In order to improve the snap connection effect, two locking members 13 are oppositely arranged, respectively located on the upper and lower sides of the anchor box 3.

[0083] When pushing the outer row of anchor nails 4 out of the anchor box 3, the anchor box 3 can be plugged into the receiving cavity 12 and form a snap connection with the locking member 13, so that the anchor box 3 and the engaging head 1 form a fixed connection.

[0084] Refer to Figures 8 to 11 , the implanting system for the outer row of anchor nails includes an anchor box 3, a wire pulling assembly 6 (refer to Figure 1 ) and the implanting device for the outer row of anchor nails as in the above embodiment. The anchor box 3 stores the outer row of anchor nails 4 and is plugged and matched with the implanting device for the outer row of anchor nails; the wire pulling assembly 6 is used for threading a suture 5 for the outer row of anchor nails 4 in the anchor box 3.

[0085] When the implant system is in use, first, the external discharge anchor is assembled with the external discharge anchor 4 stored in the anchor box 3 through the implant device. Then, the wire pulling assembly 6 is used to thread the suture 5 through the external discharge anchor 4. After the suture 5 passes through the external discharge anchor 4, the implant device pushes the external discharge anchor 4 out of the anchor box 3 to complete the assembly of the implant device and the external discharge anchor. After implantation, the implant device and the anchor box 3 can be separated, and the implant device can be recycled to reduce the waste of medical resources.

[0086] Optionally, the wire pulling assembly 6 (refer to Figure 1 ) includes a buckle 61 and a metal ring 62 provided on the buckle 61. The suture 5 is threaded through the metal ring 62. By driving the metal ring 62 to move through the buckle 61, after the suture 5 passes through the external discharge anchor 4, the suture 5 can be taken out of the anchor box 3.

[0087] Optionally, the anchor box 3 includes a box body 33 and a staple component 34. One end inside the box body 33 has a plugging channel 31 for partially inserting the implant rod 2, and the other end has a staple discharging channel for the external discharge anchor 4 to slide out; the staple component 34 is arranged inside the box body 33 and is correspondingly communicated with the plugging channel 31, and the external discharge anchor 4 is clamped inside the staple component 34.

[0088] Specifically, the anchor box 3 is in a long strip shape and is composed of two upper and lower shells clamped together. A plugging channel 31 and a space for accommodating the staple component 34 are formed between the two upper and lower shells. The staple component 34 is communicated with the plugging channel 31. A staple discharging channel is formed through the side of the box body 33 far from the plugging channel 31. The staple discharging channel corresponds to the staple component 34 so that the external discharge anchor 4 can be discharged through the staple discharging channel. A notch is also formed on the side of the box body 33 for the suture 5 to penetrate into the box body 33 and then into the external discharge anchor 4.

[0089] Optionally, the staple component 34 includes two opposite staple shells 341. The external discharge anchor 4 is stored between the two staple shells 341. The staple shells 341 are movably connected to the box body 33 and an elastic sleeve 342 is sleeved at one end far from the plugging channel 31. At the inner side of the staple shell 341 and at one end far from the plugging channel 31, there is a clamping inclined surface 343, and the clamping inclined surface 343 abuts against the head end of the external discharge anchor 4. One end of the two staple shells 341 sleeved with the elastic sleeve 342 can be separated from each other so that the external discharge anchor 4 can be pushed out.

[0090] Specifically, the staple shell 341 is strip-shaped with a hollow interior. When two staple shells 341 are joined together, a storage cavity for accommodating the outer row of anchor pins 4 is formed. The outer row of anchor pins 4 includes a body and a nail head. A clamping inclined surface 343 is provided at the part of the staple shell 341 close to the nail head. The clamping inclined surface 343 can be adapted to the inclined surface of the nail head, so that the outer row of anchor pins 4 forms a surface contact with the staple shell 341. In this embodiment, the inclination angle of the clamping inclined surface 343 can be between 0° and 90°. Among them, the suture 5 passes through the threading hole of the nail head, and the staple shell 341 has a notch corresponding to and communicating with the threading hole.

[0091] An elastic sleeve 342 is sleeved on the staple shell 341 close to the nail head. The elastic sleeve 342 can be made of silica gel material or other materials, which is not limited in the present invention. The staple shell 341 itself can be separated from each other in the box body 33 through slot hole cooperation, or the two staple shells 341 can be separated from each other at one end of the elastic sleeve 342 through a hinge structure, as long as the outer row of anchor pins 4 can be smoothly discharged.

[0092] The outer row of anchor pins 4 is restricted in the box body 33 by two staple shells 341. The setting of the clamping inclined surface 343 enables the outer row of purchases to form a clamping fit with the clamping shell, and the two staple shells 341 are joined together with the cooperation of the elastic sleeve 342, so as to ensure that the outer row of anchor pins 4 remains in corresponding communication with the insertion channel 31. Then, when the implant rod 2 is inserted into the outer row of anchor pins 4 through the insertion channel 31, it can be smoothly inserted into the outer row of anchor pins 4 and can push the outer row of anchor pins 4 to move. The nail head abuts against the clamping inclined surface 343 to push the two staple shells 341 to separate from each other, and the outer row of anchor pins 4 can be smoothly pushed out of the anchor pin box 3.

[0093] Optionally, the staple shell 341 has a clamping protrusion 344, and the outer row of anchor pins 4 has a clamping groove 42 that is inserted and matched with the clamping protrusion 344.

[0094] Specifically, a plurality of clamping grooves 42 are formed on the body of the outer row of anchor pins 4, and clamping protrusions 344 are provided on the inner side wall of the staple shell 341. The clamping protrusions 344 can be polygonal, such as quadrilateral columnar or pentagonal columnar, etc. The shape of the corresponding clamping groove 42 is also polygonal.

[0095] By providing the clamping protrusion 344 and the clamping groove 42, when the outer row of anchor pins 4 is arranged in the two clamping shells, the nail head can be limited by the clamping inclined surface 343, and the body is limited by the insertion and cooperation of the clamping protrusion 344 and the clamping groove 42, so that the staple assembly 34 can limit both the nail head and the body of the outer row of anchor pins 4 at the same time, effectively improving the limiting effect on the outer row of anchor pins 4.

[0096] Optionally, the inner side wall of the box body 33 and at the position corresponding to the staple shell 341 are provided with a plurality of chutes 35 extending in different directions, and a plurality of sliding rods 345 slidably connected to the chutes 35 are provided on the outer side wall of the staple shell 341, so that one end of the two staple shells 341 sleeving the elastic sleeve 342 can be separated from or close to each other.

[0097] Specifically, four sliding rods 345 are correspondingly arranged for each staple shell 341, two are arranged on the top wall and two are arranged on the bottom wall. Correspondingly, chutes 35 are arranged on both the inner top wall and the inner bottom wall of the box body 33. Taking the top wall as an example for the specific distribution of the sliding rods 345, one sliding rod 345 is arranged close to the insertion channel 31, and the other sliding rod 345 is arranged close to the elastic sleeve 342. The arrangement mode of the sliding rods 345 on the bottom wall is the same.

[0098] The extending direction of the chute 35 is referenced by the extending direction of the insertion channel 31. The included angle between the chute 35 close to the insertion channel 31 and this extending direction is smaller, and the included angle between the chute 35 far from the insertion channel 31 and this extending direction is larger, so that one end of the two opposite staple shells 341 sleeving the elastic sleeve 342 can be separated from each other. The specific size of the included angle can be designed according to the actual size of the outer row of anchor nails 4, as long as it can ensure that the outer row of anchor nails 4 can be smoothly pushed out.

[0099] By providing the sliding rods 345 and the chutes 35 to realize the opening of the staple shell 341, other hinge structures and the like do not need to be provided during the installation of the staple component 34, which can effectively simplify the overall structural complexity and also reduce the assembly difficulty and manufacturing difficulty.

[0100] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
