Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an implantation device and an implantation system for external row anchors. Background Art

[0002] In the fields of orthopedics and sports medicine, anchors are a key implantable medical device widely used in surgeries to fix soft tissue (such as tendons and ligaments) and bone tissue in joints such as the shoulder, knee, and ankle. Anchors include inner and outer rows. The inner row anchors carry their own sutures, while the outer row anchors do not. After the inner row anchors are implanted, the sutures from the inner row anchors are introduced into the outer row anchors, which are then implanted into the designated area to complete the suture fixation.

[0003] In the prior art, anchors and implant components are used as a set. Every time an outer row anchor is implanted, the implant component is discarded, resulting in the implant component being unable to be reused, causing a waste of medical resources. Although there are implant systems in the prior art that use anchor storage devices to load anchors and cooperate with implant components for implantation, they are all suitable for inner row anchors with their own wires. Summary of the Invention

[0021] The implantation device for outer row anchors as described in any one of the first aspects;

[0022] An anchor box storing outer row anchors and plugging with the outer row anchor implantation device;

[0023] A pull wire assembly is used for threading sutures through the outer row of anchors in the anchor box.

[0024] Optionally, the anchor box includes:

[0025] A box body, wherein one end of the box body has an insertion channel for partially inserting the implant rod, and the other end has a nail row channel for sliding out the outer row of anchor nails;

Then, after the outer row anchor is implanted, the implantation device can be recycled to improve the utilization rate of the implantation device and reduce the waste of medical resources; on the other hand, during the implantation process of the outer row anchor, a dynamic spiral coupling is formed by the threaded cooperation between the abutting portion and the threaded section, which not only avoids the problem of jamming and wear easily generated by traditional threaded connection during the transmission process, but also reduces the contact area of the thread, thereby reducing vibration and noise during the transmission process, and improving the accuracy of axial displacement control, so that the stability and reliability of the implantation process are improved, which is conducive to the high-precision implantation of the outer row anchor during the operation.

[0032] Secondly, when using the implant system, the outer row anchors are first assembled by inserting the implant device into the outer row anchors in the anchor box. A pull wire assembly is then used to thread sutures through the outer row anchors. Once the sutures are passed through the outer row anchors, the implant device pushes the outer row anchors out of the anchor box, completing the assembly of the implant device and the outer row anchors. After implantation, the implant device and the anchor box can be separated and recycled, reducing the waste of medical resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The embodiments of the present invention disclose an implantation device and an implantation system for external row anchors.

[0056] Reference 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 connecting channel; the implant rod 2 is provided in the connecting channel, and one end of the implant rod 2 passing through the connecting 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 position; the handle 21 is provided 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, which is engaged in the thread of the threaded section 22, so that when the implant rod 2 rotates, the implant rod 2 is driven to move axially relative to the snap-fit head 1 to implant the outer row anchor 4 into the designated position.

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

[0058] A threaded section 22 is provided on the portion of the implant rod 2 located within the connection channel of the locking head 1. The threads within the threaded section 22 can be trapezoidal or triangular, with a guide groove formed between adjacent threads. An abutment portion 14 is provided on the locking head 1. At least a portion of the abutment portion 14 can extend into the connection channel and be inserted into the guide groove, thereby forming a snap fit with the threads. In this embodiment, the abutment portion 14 is a screw. A threaded hole is provided through the locking head 1 that is connected to the connection channel. The screw is threadedly connected to the threaded hole, and the lower end of the screw is inserted into the aforementioned guide groove. In other embodiments, the abutment portion 14 can be a clamping rod. In this case, the clamping head 1 only needs to have a through hole to allow one end of the clamping rod to 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. It is sufficient that it can form a snap fit with the threads of the threaded section 22.

[0059] During assembly, one end of the implant rod 2 is passed through the connecting channel, and the end of the implant rod 2 passing through the connecting channel is inserted into the anchor box 3, so that the implant rod 2 is inserted into the outer row anchor 4 and forms a fixed connection with the outer row anchor 4. At this time, the outer row anchor 4 can be threaded to pass the suture 5 through the outer row anchor 4, and the implant rod 2 is continued to be pushed, and the implant rod 2 squeezes the outer row anchor 4 until the outer row anchor 4 is pushed out of the anchor box 3. During implantation, the gripping handle 21 drives the implant rod 2 to rotate, and the abutment portion 14 is tightly pressed against the thread in the threaded section 22, so that the implant rod 2 moves axially relative to the engaging head 1 during the rotation process, thereby gradually implanting the outer row anchor 4 into the designated position. After the implantation is completed, the implant rod 2 is separated from the outer row anchor 4, and the anchor box 3 is then pulled out of the implant rod 2. The anchor box 3 can be discarded, and the implant device can be recycled. Therefore, when the implantation device for the outer row anchor is in use, on the one hand, the outer row anchor 4 is stored in the anchor box 3, and the implantation rod 2 and the anchor box 3 are set in the form of shell plug-in assembly, so that the implantation rod 2 and the anchor box 3 form a detachable connection. Then, after the outer row anchor 4 is implanted, the implantation device can be recycled to improve the utilization rate of the implantation device and reduce the waste of medical resources; on the other hand, during the implantation process of the outer row anchor 4, a dynamic spiral coupling is formed by the threaded cooperation between the abutment portion 14 and the threaded segment 22, which not only avoids the problem of jamming and wear of traditional threaded connections during transmission, but also reduces the contact area of the thread, thereby reducing vibration and noise during transmission, and improving the accuracy of axial displacement control, so that the stability and reliability of the implantation process are improved, which is conducive to the high-precision implantation of the outer row anchor 4 during surgery.

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

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

[0062] Reference Figures 3 to 6 Optionally, the end of the implant rod 2 away from the handle 21 has a connecting section 23 that can be inserted into the outer row anchor 4, and the head end of the connecting section 23 has a connecting protrusion 24, which is used to press against the inner wall of the nail head of the outer row anchor 4.

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

[0064] Optionally, the connecting protrusion 24 is arc-shaped, and the inner sides of the nail heads of the outer row of anchor nails 4 have stepped holes 41 that are tightly pressed against the connecting protrusion 24 .

[0065] Specifically, a stepped hole 41 is provided inside the nail head of the outer row of anchor nails 4, and the hole diameter decreases along the insertion direction of the connecting section 23. The arc surface of the connecting protrusion 24 can press against the hole wall of the small diameter hole in the stepped hole 41, thereby forming an interference fit.

[0066] The outer row anchors 4 and the connecting section 23 are fixed by forming an interference fit between the connecting section 23 and the outer row anchors 4, so that radial compression is formed between the connecting protrusion 24 and the outer row anchors 4, so that the heads of the outer row anchors 4 can be smoothly driven to rotate synchronously when the implant rod 2 rotates. Moreover, compared with the connection through threads, the interference fit formed by radial extrusion of the arc surface can increase the contact area between the two, thereby achieving more stable force transmission and higher connection strength, so as to further ensure the high-precision implantation of the outer row anchors 4.

[0067] Optionally, the cross section of the connecting section 23 is polygonal and the side wall of the connecting section 23 fits with the inner side wall of the outer row of anchors 4 .

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

[0069] Reference Figure 2 Optionally, the implant rod 2 is inserted into the handle 21 , and the handle 21 is provided with a locking portion 211 , which 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. The locking portion 211 can extend into the blind hole and press 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 has a corresponding threaded hole. The locking portion 211 can also be an insertion rod. In this case, the handle 21 only needs to have a corresponding through hole connected to the blind hole, and a corresponding card hole can also be provided on the implant rod 2 for the insertion of the insertion rod. The specific structure of the locking portion 211 can be designed according to the actual installation difficulty, and the present invention does not limit it.

[0071] By setting the handle 21 and the implant rod 2 as a detachable connection, any structure can be easily replaced, thereby improving the utilization rate of the structure and reducing the waste of medical resources. At the same time, the handle 21 and the implant rod 2 can be fixed by simple plug-in cooperation, making the installation process simple and easy to operate.

[0072] Reference Figure 2 、 Figure 3 and Figure 7 Optionally, the implantation device for the outer row anchor further comprises a protective sleeve 15 . The protective sleeve 15 is sleeved on the threaded section 22 of the implant rod 2 , and the abutment portion 14 passes through the protective sleeve 15 and is engaged with the thread of the threaded section 22 .

[0073] Specifically, one end of the protective sleeve 15 is fixedly connected to the snap-fit head 1, and the two can be an integrated structure, or they can be fixed together by bonding or welding. The other end of the protective sleeve 15 passes through the connecting channel, and the implant rod 2 is located in the protective sleeve 15. The inner diameter of the protective sleeve 15 is larger than the diameter of the implant rod 2, so that a movable gap is formed 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 abutment 14 for the abutment 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 box 3.

[0074] By providing the protective cover 15, on the one hand, it can play a guiding role during the insertion of the implant rod 2 to ensure that the implant rod 2 will not deviate, and on the other hand, it can also protect the longer 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 an outer wall of the protective cover 15 .

[0076] Specifically, the protective cover 15 is plugged into the connection channel. A fixing portion 11 is provided on the engaging head 1. The fixing portion 11 partially extends into the connection channel. A fixing groove is provided on the outer wall of the protective cover 15. The fixing portion 11 can abut against the bottom wall of the fixing groove, thereby fixing the protective cover 15 to 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 plug-in rod or other structure, as long as it can fix the protective cover 15.

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

[0078] Optionally, the protective cover 15 has a guide block 151 , the anchor box 3 has an insertion channel 31 for inserting the protective cover 15 , and the insertion channel 31 has a guide groove 32 for sliding the guide block 151 .

[0079] Specifically, an insertion channel 31 is defined within the anchor box 3, communicating with the outer row of anchors 4. A guide groove 32 is provided on the sidewall of the insertion channel 31, extending along the length of the insertion channel 31. The guide block 151 fits within the guide groove 32. In this embodiment, a rectangular parallelepiped guide block 151 is provided on each of the upper and lower sides of the protective cover 15. Accordingly, a guide groove 32 is provided on each of the upper and lower sides of the insertion channel 31.

[0080] By providing the guide block 151 and the guide groove 32 , when plugged into the anchor box 3 , the guide block 151 and the guide groove 32 can accurately limit the moving direction, thereby ensuring that the implant rod 2 is accurately inserted into the outer row anchors 4 .

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

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

[0083] When the outer row of anchors 4 are pushed out of the anchor box 3 , the anchor box 3 can be inserted into the accommodating cavity 12 and snap-fit with the locking member 13 , thereby forming a fixed connection between the anchor box 3 and the snap-fit head 1 .

[0084] Reference Figures 8 to 11 The external row anchor implantation system includes an anchor box 3, a pull wire assembly 6 (refer to Figure 1 ) and the outer row anchor implantation device as described in the above embodiment. The anchor box 3 stores the outer row anchors 4 and is plugged into the outer row anchor implantation device; the pull wire assembly 6 is used to thread the suture 5 through the outer row anchors 4 in the anchor box 3.

[0085] When using the implant system, the outer row anchor implant device is first connected to the outer row anchors 4 stored in the anchor box 3. Then, the pull wire assembly 6 is used to thread the sutures 5 through the outer row anchors 4. After the sutures 5 pass through the outer row anchors 4, the implant device pushes the outer row anchors 4 out of the anchor box 3, completing the assembly of the implant device and the outer row anchors. After the implant is completed, 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 assembly 6 (see Figure 1 ) includes a buckle 61 and a metal ring 62 arranged on the buckle 61. The suture 5 is passed through the metal ring 62. The buckle 61 drives the metal ring 62 to move, so that the suture 5 passes through the outer row of anchors 4 and then is brought out of the anchor box 3.

[0087] Optionally, the anchor box 3 includes a box body 33 and a staple assembly 34. One end of the box body 33 has an insertion channel 31 for partially inserting the implant rod 2, and the other end has a staple channel for sliding out the outer row anchors 4; the staple assembly 34 is disposed in the box body 33 and communicates with the insertion channel 31, and the outer row anchors 4 are clipped into the staple assembly 34.

[0088] Specifically, the anchor box 3 is in the shape of an elongated strip and consists of two upper and lower shells that are clamped together. An insertion channel 31 and a space for accommodating a staple assembly 34 are formed between the upper and lower shells. The staple assembly 34 is connected to the insertion channel 31. A staple row channel is provided on the side of the box body 33 away from the insertion channel 31. The staple row channel corresponds to the staple assembly 34 so that the outer row of anchor staples 4 can be discharged through the staple row channel. A notch is also provided on the side of the box body 33 for the suture 5 to pass through the box body 33 and then into the outer row of anchor staples 4.

[0089] Optionally, the staple assembly 34 includes two opposing staple shells 341, and the outer row anchors 4 are stored between the two staple shells 341. The staple shell 341 is movably connected to the box body 33 and is sleeved with an elastic sleeve 342 at the end away from the insertion channel 31. The inner side of the staple shell 341 and the end away from the insertion channel 31 have a clamping slope 343, and the clamping slope 343 abuts against the head end of the outer row anchors 4. The ends of the two staple shells 341 sleeved with the elastic sleeve 342 can be separated from each other so that the outer row anchors 4 are pushed out.

[0090] Specifically, the staple shell 341 is elongated and hollow. When two staple shells 341 are joined together, they form a storage chamber for the outer row anchors 4. The outer row anchors 4 comprise a body and a head. The portion of the staple shell 341 near the head is provided with a beveled engaging surface 343 that mates with the bevel of the head, thereby ensuring surface contact between the outer row anchors 4 and the staple shell 341. In this embodiment, the angle of the beveled engaging surface 343 can range from 0° to 90°. The suture 5 is threaded through the threading hole in the head, and the staple shell 341 has a notch corresponding to the threading hole.

[0091] An elastic sleeve 342 is provided near the nail head of the staple shell 341. The elastic sleeve 342 may be made of silicone or other materials, and the present invention is not limited thereto. The staple shell 341 itself can be separated from the box body 33 by means of a slotted hole. Alternatively, the two staple shells 341 can be separated by adjusting one end of the elastic sleeve 342 through a hinged structure, as long as the outer row of anchor nails 4 can be smoothly ejected.

[0092] The outer row anchor nails 4 are restricted in the box body 33 by the two staple shells 341, and the setting of the snap-fitting inclined surface 343 enables the outer row nails to form a snap-fitting fit with the snap-fitting shells, and cooperates with the elastic sleeve 342 to splice the two staple shells 341 together, thereby ensuring that the outer row anchor nails 4 and the insertion channel 31 maintain corresponding communication. When the implant rod 2 is inserted into the outer row anchor nails 4 through the insertion channel 31, it can be smoothly inserted into the outer row anchor nails 4 and can push the outer row anchor nails 4 to move. The nail head abuts against the snap-fitting inclined surface 343, thereby pushing the two staple shells 341 to separate from each other, and the outer row anchor nails 4 can be smoothly pushed out of the anchor box 3.

[0093] Optionally, a clamping protrusion 344 is provided in the staple shell 341 , and the outer row of anchor staples 4 has a clamping groove 42 that is plugged into and fits with the clamping protrusion 344 .

[0094] Specifically, a plurality of snap-fit grooves 42 are provided on the body of the outer row of anchor nails 4, and a snap-fit protrusion 344 is provided on the inner side wall of the nail shell 341. The snap-fit protrusion 344 can be polygonal, such as a quadrilateral column or a pentagonal column, etc., and the corresponding snap-fit groove 42 is also polygonal in shape.

[0095] By setting the snap-fitting protrusions 344 and the snap-fitting grooves 42, when the outer row anchor nails 4 are set in the two snap-fitting shells, the nail heads can be limited by the snap-fitting inclined surfaces 343, and the main body is limited by the snap-fitting protrusions 344 and the snap-fitting grooves 42, so that the nail assembly 34 can limit the nail heads and the main body of the outer row anchor nails 4 at the same time, effectively improving the limiting effect of the outer row anchor nails 4.

[0096] Optionally, the inner wall of the box body 33 and the position corresponding to the staple shell 341 have multiple sliding grooves 35 extending in different directions, and the outer wall of the staple shell 341 has multiple sliding rods 345 slidably connected to the sliding grooves 35, so that the ends of the two staple shells 341 that are sleeved on the elastic sleeve 342 can be separated from or approached from each other.

[0097] Specifically, each staple housing 341 is provided with four slide bars 345: two on the top wall and two on the bottom wall. Correspondingly, slide grooves 35 are provided on both the inner top and bottom walls of the box body 33. The specific distribution of the slide bars 345 can be taken as an example, with one slide bar 345 positioned near the insertion channel 31 and another slide bar 345 positioned near the elastic sleeve 342. The slide bars 345 on the bottom wall are arranged in the same manner.

[0098] The extension direction of the slide groove 35 is based on the extension direction of the insertion channel 31. The angle between the slide groove 35 close to the insertion channel 31 and the extension direction is smaller, and the angle between the slide groove 35 away from the insertion channel 31 and the extension direction is larger, so that the two opposite ends of the elastic sleeve 342 of the staple shell 341 can be separated from each other. The specific size of the angle can be designed according to the actual size of the outer row anchor nails 4 to ensure that the outer row anchor nails 4 can be pushed out smoothly.

[0099] By setting the slide rod 345 and the slide groove 35 to achieve the opening of the staple shell 341, the staple assembly 34 does not need to be equipped with other hinges or other structures during installation, which can effectively simplify the overall structural complexity and reduce the difficulty of assembly and manufacturing.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
