Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and more specifically, to a device for processing full-suture anchors. Background Technology
[0002] In sports medicine and orthopedic surgery, suture anchors are widely used for soft tissue-to-bone fixation, such as rotator cuff repair and ligament reconstruction. Traditional suture anchors are typically made of metal or absorbable polymers, and anchoring methods mainly rely on mechanical embedding, expansion fixation, or threaded insertion. While these anchors can provide strong fixation, they may cause significant trauma to the bone tissue during implantation and even affect postoperative bone healing. Furthermore, metal anchors may cause postoperative radiographic interference, while the degradation period and mechanical properties of absorbable anchors limit their application.
[0003] In recent years, braided suture anchors have gradually emerged as a new solution. These anchors utilize flexible materials, allowing them to better adapt to bone tissue morphology, reduce bone damage, and avoid foreign body residue. However, the manufacturing of suture anchors faces significant challenges: First, the precise threading of the braided anchor body and the sutures requires high consistency; traditional manual threading is inefficient and prone to angular deviations, leading to uneven anchor deployment. Second, existing processing equipment struggles to simultaneously control the anchor body's clamping stability and the suture threading path, easily causing damage to the braided structure or imbalanced suture tension distribution. Furthermore, subtle differences in the suture insertion angle and spacing ratio can significantly affect the anchor's cohesion performance and pull-out resistance.
[0004] To address the aforementioned issues, this application proposes a fully stitched anchor processing device. Summary of the Invention
[0005] The purpose of this invention is to provide a full-stitch anchor processing device, which has the characteristics of being able to precisely control the stitch threading path, adapt to diverse nail body structures, and take into account both processing efficiency and reliability.
[0006] The objective of this invention can be achieved through the following technical solution: a full-seam anchor processing device for producing full-seam anchor modules, wherein the full-seam anchor module includes an anchor body and a thread, both of which are woven fabrics. The thread passes through the anchor body sequentially. The processing device fixes the anchor body with two clamping blocks. The clamping blocks are provided with several staggered abutment members that bend the anchor body back and forth. The abutment members are provided with through holes for threading. After fixing the anchor body, the thread is passed through the through holes by a threader to complete the processing of the full-seam anchor module.
[0007] Preferably, the clamping block is a first fixed clamping block and a second fixed clamping block, and the abutting member is formed on the first fixed clamping block and the second fixed clamping block respectively.
[0008] Preferably, the abutting member consists of a plurality of first angle abutting posts and second angle abutting posts to ensure the angle at which the thread enters the nail body. The first angle abutting posts are fixed on the first fixing block, and the second angle abutting posts are fixed on the second fixing block and correspond to the first fixing block. The first angle abutting posts are provided with first thread holes. The abutting groove and the abutting block clamp the middle of the nail body and are used for the thread to pass through along the length direction of the nail body.
[0009] Preferably, the first fixing block has a groove formed in the middle of one end near the second fixing block, and the second fixing block has a block corresponding to the groove. The groove and the block clamp the nail body in the middle and are used for the horizontal passage of the sewing thread.
[0010] Preferably, the first angle contact post and the groove near the second fixing block are formed with a positioning groove for partial embedding of the nail body.
[0011] Preferably, the clamping blocks are a first clamping block and a second clamping block slidably connected to the base plate via a slide rail, and the abutting elements are respectively formed on the first clamping block and the second clamping block.
[0012] Preferably, the abutting member comprises a plurality of first abutting posts and second abutting posts, wherein the first abutting posts are fixed on the first clamping block, and the second abutting posts are fixed on the second clamping block and correspond to the first abutting posts.
[0013] Preferably, a third wire hole is provided through the first contact post, and a fourth wire hole is provided through the second contact post.
[0014] The beneficial effects of this invention are:
[0015] The present invention fixes the nail body by setting two relatively moving clamps and abutting parts. The distance between the abutting parts can determine the bending position and the stitch length between each bend, thereby making the batch processing of full gap anchor modules consistent.
[0016] This invention, through the concentric thread-passing holes on the contact parts, can determine the thread-passing path when the nail body is fixed by two clamping blocks, thereby accurately determining the thread-passing position on the nail body and achieving standardized and uniform production.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0027] like Figure 1 - Figure 6 As shown, this embodiment provides a full-seam anchor processing device for producing full-seam anchor modules. The full-seam anchor module includes an anchor body 1 and a seam 2. The anchor body 1 is woven from 12 strands of ultra-high molecular weight polyethylene yarn using a physical weaving process, and is white in color. The seam 2 is woven from 16 strands of ultra-high molecular weight polyethylene yarn using a physical weaving process, and the seam 2 passes through the anchor body 1 in sequence.
[0028] When using the full-gap anchor module, insert the nail body 1 into the fixing hole, and pull the two ends of the sewing thread 2 against the two ends of the nail body 1. The traction of the sewing thread 2 will cause the nail body 1 to come into contact with the inside of the fixing hole to complete the fixation.
[0029] Specifically, the full-seam anchor processing device fixes the nail body 1 with two clamping blocks. The clamping blocks are provided with several staggered abutment members that bend the nail body 1 back and forth. The abutment members are provided with through holes for threading. After fixing the nail body 1, the thread 2 is passed through the through holes by a threader to complete the processing of the full-seam anchor module. In this embodiment, the threader can be a threading needle. When in use, the thread 2 is passed through the tail of the threading needle, and the sharp part of the other end of the threading needle passes through the through hole and the nail body 1. Then the threading needle is removed.
[0030] Furthermore, one clamping block in the processing device is fixedly installed, and the other clamping block moves closer to or away from the fixed clamping block under the action of the driving mechanism. The driving mechanism can be an electric cylinder, a pneumatic cylinder, a linear track, etc. When the driving mechanism drives the two clamping blocks away, it is convenient to place or remove the nail body 1. When the driving mechanism drives the two clamping blocks to close, the nail body 1 is bent in a reciprocating state so that the sewing thread 2 can pass through.
[0031] Example 1
[0032] like Figure 2 As shown, from one end of the nail body 1 to the center point 100, there are four threading points: 10a, 10b, 10c, and 10d. The angle at which the thread 2 enters the nail body 1 from the threading point is 20°. The distance between point 10a and the end face of the nail body 1 is A1, the distance between point 10a and point 10b is A2, the distance between point 10b and point 10c is A3, the distance between point 10c and point 10d is A4, and the distance between 10d on both sides of the center point 100 is A5. The ratio of distances A1:A2:A3:A4:A5 is 2:3:2:3:2.
[0033] Furthermore, the overall length of the nail body 1 is 12mm-36mm.
[0034] Furthermore, the angle at which the suture 2 enters the nail body 1 from the threading point is 60°, and the distance ratio of A1:A2:A3:A4:A5 is 2:5:2:5:3.
[0035] like Figures 4-5 As shown, the clamping blocks in the full-seam anchor processing device are a first fixed clamping block 31 and a second fixed clamping block 32, and the abutting elements are respectively formed on the first fixed clamping block 31 and the second fixed clamping block 32.
[0036] To determine the angle at which the suture 2 passes through the nail body 1, the abutment components are a plurality of first angle abutment posts 3101 and second angle abutment posts 3201 that ensure the angle at which the suture 2 enters the nail body 1. The first angle abutment posts 3101 are fixed to the first fixing block 31, and the second angle abutment posts 3201 are fixed to the second fixing block 32 and correspond to the first fixing block 31. The first angle abutment posts 3101 are provided with a first thread hole 3104, and the second angle abutment posts 3201 are provided with a second thread hole 3203 that cooperates with the first thread hole 3104 to form a channel through which the suture 2 passes. In this embodiment, the angle at which the suture 2 passes through the nail body 1 is determined by the angle of the first angle abutment posts 3101 and the second angle abutment posts 3201, so as to accurately control the threading path and ensure the consistency of batch processing.
[0037] Furthermore, in order to ensure that the suture 2 passes through the middle of the nail body 1, the first fixing block 31 has a groove 3102 formed in the middle of one end near the second fixing block 32, and the second fixing block 32 has a block 3202 corresponding to the groove 3102. The groove 3102 and the block 3202 clamp the middle of the nail body 1 and are used for the suture 2 to pass through along the length of the nail body 1.
[0038] Furthermore, in order to facilitate the positioning of the nail body 1 in the processing device, the first angle contact post 3101 and the groove 3102 near the second fixing block 32 are formed with a positioning groove 3103 for partial embedding of the nail body 1. The positioning groove 3103 can prevent the nail body 1 from shifting during processing.
[0039] Example 2
[0040] like Figure 6 As shown, the clamping blocks in the full-seam anchor processing device are a first clamping block 41 and a second clamping block 42, which are slidably connected to the base plate 4 via a slide rail 401. The abutting elements are respectively formed on the first clamping block 41 and the second clamping block 42. The abutting elements are a plurality of first abutting posts 411 and second abutting posts 421. The first abutting posts 411 are fixed on the first clamping block 41, and the second abutting posts 421 are fixed on the second clamping block 42 and correspond to the first abutting posts 411. A third wire hole 4111 is provided through the first abutting post 411, and a fourth wire hole 4211 is provided through the second abutting post 421.
[0041] When in use, the first clamping block 41 is brought close to the second clamping block 42 to clamp the nail body 1. After the movement is in place, the through holes on the first abutment post 411 and the second abutment post 421 are concentric. The sewing thread 2 is then passed through the through holes by a threading needle to complete the threading process.
[0042] It is understood that the present invention fixes the nail body by means of adjustable spacing clamps and abutments, precisely controlling the bending position and the length of the stitch; and by using the concentric threading holes on the abutments, the stitch path is determined during fixing, ensuring the accuracy of the stitch passing position, thereby realizing the standardized mass production of anchor nails.
[0043] Manufacturing process of full-slot anchor modules:
[0044] The first fixing block 31 is fixed, and the second fixing block 32 is installed in conjunction with the first fixing block 31 through a linear drive mechanism. With the nail body 1 in a straight position, it adheres to the top of the first angle contact post 3101 through the positioning groove 3103, ensuring that the middle part of the nail body 1 is located at the position of the groove 3102 and the block 3202. The drive mechanism drives the second fixing block 32 to push against the first fixing block 31 to clamp the nail body 1. At this time, the first wire hole 3104 and the second wire hole 3203 are concentric, i.e., as shown... Figure 4 In the state shown, the thread 2 is passed through the first thread hole 3104 and the second thread hole 3203 by the threader. During the process of passing the thread 2, it is simultaneously passed into the nail body 1 to form a semi-finished full-gap anchor module.
[0045] The drive mechanism opens the second fixing block 32, removing the semi-finished full-gap anchor module, which is as follows. Figure 3 As shown, flatten nail body 1 to the desired position. Figure 2 As shown in the diagram, then at the center point 100, bend nail body 1 into a U-shape, ultimately forming as shown. Figure 1 The finished product of the full-slot anchor module is shown.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
