Description

Technical Field

[0001] This invention belongs to the field of orthopedic surgical instrument technology, specifically relating to a coracoclavicular ligament reconstruction suture device with guiding and suture fixation functions. Background Technology

[0002] The coracoclavicular ligament is an important ligamentous structure connecting the coracoid process of the scapula to the distal end of the clavicle, playing a crucial role in maintaining the stability of the acromioclavicular joint. When the coracoclavicular ligament tears or ruptures, it often leads to acromioclavicular joint dislocation, joint instability, and other problems, severely impacting the patient's shoulder joint function and quality of life. Currently, the main clinical approach to repairing coracoclavicular ligament ruptures is artificial ligament reconstruction surgery. This involves wrapping an artificial ligament around the coracoid process and guiding it into the clavicular foramen for fixation, thereby restoring its anatomical structure and functional stability.

[0003] In coracoclavicular ligament reconstruction, the artificial ligament needs to pass through the clavicular foramen beneath the coracoid process along a specific path, and then be brought back to the distal end of the clavicle for fixation. This process often requires the assistance of specialized suture threading instruments to complete the tasks of threading the suture and ligament traction. Some existing suture threading instruments have complex structures, are inconvenient to operate, or have poor connection stability, are prone to suture detachment, and have inaccurate guiding control during use, resulting in low threading efficiency, high operational risks, and affecting the accuracy and safety of the reconstruction surgery.

[0004] Especially when pulling back artificial ligaments, the lack of a stable locking structure for the ligament loops makes them prone to shifting, falling off, or becoming entangled during the pull-back process, hindering intraoperative operations and increasing the surgeon's workload. Simultaneously, some suture threaders lack reliable suture fixation mechanisms, causing the suture to loosen or break during pushing, affecting intraoperative guidance. Furthermore, existing devices also have certain shortcomings in suture head sliding control, ease of structural maintenance, and intraoperative grip stability, necessitating further optimization of the structural design to improve overall operational performance. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a coracoclavicular ligament reconstruction suture device with guiding and suture fixation functions. It can achieve reasonable structure, stable connection, accurate threading, and convenient operation, and is suitable for guiding and pulling back artificial ligaments in coracoclavicular ligament reconstruction surgery.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A coracoclavicular ligament reconstruction suture device with guiding and lead wire fixing functions includes a suture main rod, one end of which is movably connected to a suture head, and the other end of which is connected to a handle; The threading head is connected to a lead wire, which passes through the threading main rod and the handle; A pusher head is slidably connected to the main threading rod, and the pusher head is used to push the threading head to slide on the main threading rod.

[0007] Furthermore, a first locking groove is provided on the main threading rod near the threading head; The threading head includes a head body, on which a second locking groove is provided, and the second locking groove is disposed opposite to the first locking groove; During the process of pulling back the artificial ligament, the two ends of the loop on the artificial ligament are inserted into the first and second locking slots, respectively.

[0008] Furthermore, one end of the main threading rod is symmetrically provided with positioning holes; One end of the head body is fixedly connected to a guide post corresponding to the positioning hole, and the guide post passes through the positioning hole.

[0009] Furthermore, the other end of the main threading rod is provided with a guide groove that communicates with the positioning hole; the number of guide grooves is set to two, and the two guide grooves are mirror images of each other; The bottom of the pusher head is fixedly connected to a locking block that matches the guide groove; One end of the guide post is connected to the locking block.

[0010] Furthermore, a first lead wire hole is provided through the main wire rod, and a second lead wire hole is provided through the handle, with the axes of the second lead wire hole and the first lead wire hole on the same straight line; The lead wire passes through the first lead hole and the second lead hole.

[0011] Furthermore, one end of the second lead hole has an arc-shaped angle.

[0012] Furthermore, a pin hole is provided through one end of the head body, and a pin is inserted into the pin hole; One end of the lead wire is provided with a ring head, which is fitted onto the pin. The pin has an annular groove on its outer side, and one end of the pin is fixedly connected to a retaining plate.

[0013] Furthermore, a storage groove is provided at the bottom of the head body, which is used to store the lead wire during the threading process.

[0014] Furthermore, one end of the handle is provided with a plug groove, and one end of the threading main rod is inserted into the plug groove.

[0015] Furthermore, the end of the handle is mirror-image-equipped with a hook, and during the process of pulling back the artificial ligament with the guide wire, the movable end of the guide wire is wrapped around the hook. The outer surface of the handle is provided with anti-slip strips.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This threader improves the stability and sliding control accuracy of the threading head during the guiding process by setting a guide post and guide groove cooperation structure between the threading main rod and the threading head. This effectively solves the problems of inaccurate guidance and unstable connection in the existing threader during the threading process, and ensures the accuracy of the artificial ligament on the threading path.

[0017] By setting a first locking groove and a second locking groove at the relative positions of the main threading rod and the threading head, the ring structure can be stably clamped during the pull-back of the artificial ligament, preventing the ring from shifting or slipping during the pull-back process. This solves the problem of unstable pull-back and easy displacement of the artificial ligament in the existing structure, and improves the reliability of ligament traction during the operation.

[0018] By setting a pin inside the suture head and opening an annular groove on the pin to fix the annular head of the lead wire, and at the same time equipping it with a baffle structure to axially limit the pin, a stable connection of the lead wire is achieved in the suture head. This effectively avoids the problem of the lead wire loosening or falling off during the process of threading or pulling during the operation, and improves the continuity and safety of suture threading during the operation.

[0019] By setting a storage slot at the bottom of the head and body to temporarily accommodate excess suture length, the suture can be prevented from tangling or being subjected to uneven force during threading. This solves the problem of sutures easily getting tangled and affecting the smoothness of operation in traditional structures, thereby improving threading efficiency and surgical quality.

[0020] By connecting the end of the threading rod to the handle using a plug-in structure, the overall structure is secure and reliable, and it is easy to disassemble and clean after surgery. This solves the problems of inconvenient maintenance and high risk of repeated use of traditional threaders, and enhances the practicality and durability of the instrument.

[0021] By setting a symmetrical hook structure at the end of the handle, the movable end of the suture can be hung on it for tension adjustment and direction control, which further improves the control of the accuracy of suture traction during the operation and solves the problem of inconvenience for the surgeon due to the lack of suture fixation means during traction.

[0022] By adding anti-slip strips to the outside of the handle, the friction of the hand during surgery is enhanced, avoiding slippage caused by sweaty hands or instrument contamination. This solves the problem of unstable grip of the threader during surgery and affects the accuracy of operation, thus improving the overall safety and reliability of operation from the details.

[0025] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Example 1

[0026] See Figure 1-9A coracoclavicular ligament reconstruction suture device with guiding and suture fixation functions includes a suture main rod 1, which is a hollow structure with an internal channel for accommodating a suture 4. A suture head 2 is movably inserted into one end of the main rod 1, and the suture head 2 is stably connected to the main rod 1 via a guiding structure. A handle 6 is connected to the other end of the main rod 1, and the handle 6 is detachably connected via a plug-in fit for easy postoperative cleaning and maintenance. A suture 4, made of flexible high-strength medical material, is connected to the suture head 2, with one end fixed inside the suture head 2 and the other end extending from the tail of the handle 6. The suture 4 passes through the internal channel of the main rod 1 and the handle 6, and is used for traction and placement of the artificial ligament during surgery. A pusher 5 is slidably connected to the main rod 1, and the pusher 5, through a guiding fit, drives the suture head 2 to slide axially along the main rod 1, thereby realizing the forward and retraction operation of the suture head 2.

[0027] See Figure 1-5 The main threading rod 1 has a first locking groove 12 at one end near the threading head 2. The first locking groove 12 is used to fix the ring structure of the artificial ligament when it is pulled back during the operation. The threading head 2 includes a head body 21, which is a slender cylindrical structure that fits the operating space during the operation. The head body 21 has a second locking groove 211, which is opposite to the first locking groove 12. The two grooves cooperate to clamp the two ring ends of the artificial ligament. This structure can achieve stable clamping during the pull-back of the artificial ligament, avoid slippage or displacement, and improve the safety and accuracy of the operation during the operation.

[0028] See Figure 1-5 One end of the main threading rod 1 is symmetrically provided with positioning holes 13, which are used to cooperate with the guide structure of the threading head 2 to form a stable insertion; one end of the head body 21 is fixedly connected with a guide post 24 corresponding to the positioning hole 13. The guide post 24 passes through the positioning hole 13 and is inserted into the main threading rod 1 to ensure the axial and radial stability between the threading head 2 and the main threading rod 1, and maintain its guiding and anti-swaying ability during the sliding process of the threading head 2.

[0029] See Figure 1-8 The other end of the main threading rod 1 is provided with a guide groove 14 that communicates with the positioning hole 13. There are two guide grooves 14, which are symmetrically arranged on the left and right sides of the main threading rod 1. The two guide grooves 14 are mirror-arranged to match the guide structure. The bottom of the push head 5 is fixedly connected to a locking block 51 that matches the guide groove 14. The locking block 51 moves along the guide groove 14 through sliding cooperation, driving the guide column 24 to move forward or backward as a whole, realizing the pushing and retraction of the threading head 2. One end of the guide column 24 is connected to the locking block 51 to form an integrated linkage structure, ensuring the guiding accuracy and smooth sliding during the threading process.

[0030] See Figure 8-9The main threading rod 1 has a first lead hole 11, which is arranged along the longitudinal center of the main threading rod 1, and is used to lead the lead 4 out from the inside of the threading head 2 into the main rod channel. The handle 6 has a second lead hole 62, which is located on the central axis of the handle 6 and is aligned with the axis of the first lead hole 11 to ensure that the lead 4 is guided smoothly. The lead 4 passes through the first lead hole 11 and the second lead hole 62. The overall layout is simple and avoids the lead 4 from folding, blocking or coming out of the groove during use, and ensures that the lead 4 is pulled smoothly during the operation.

[0031] See Figure 8-9 The second lead hole 62 has an arc-shaped angle 621 at one end. The arc-shaped angle 621 is located at the lead outlet and has a rounded transition structure. It is used to reduce the bending angle of the lead 4 during the pulling process, avoid wear, breakage or unstable tension of the lead surface caused by sharp bending, and improve the guiding performance and service life of the threader.

[0032] See Figure 6 One end of the head body 21 has a through-hole 23, into which a pin 3 is inserted. The pin 3 is used to connect and fix the head structure of the lead wire 4. One end of the lead wire 4 is provided with an annular head 41, which is made by molding in one piece, and has a strong structure. The annular head 41 is sleeved on the pin 3 and embedded in the annular groove 31 of the pin 3. The annular groove 31 is an annular groove structure used to limit the axial movement of the annular head 41. One end of the pin 3 is fixedly connected to a retaining plate 32. The retaining plate 32 is slightly larger than the diameter of the pin hole 23, which serves as a limit to prevent the pin 3 from sliding out of the head body 21 as a whole, and to ensure the stable fixation of the lead wire 4 in the wire threading head 2.

[0033] See Figure 5 The bottom of the head body 21 is provided with a storage groove 22, which is a groove structure for accommodating the redundant section of the lead wire 4, and is located in the lower part of the inner cavity of the head body 21. During the wire threading process, the part of the lead wire 4 that is not fully pulled out can be neatly stored in the storage groove 22, so as to avoid the lead wire from getting tangled, knotted or unevenly stressed inside the wire threading head 2, and ensure that the wire threading process proceeds smoothly.

[0034] See Figure 8-9 One end of the handle 6 is provided with a plug groove 61. The plug groove 61 is a slot structure that matches the tail end of the threading main rod 1. After one end of the threading main rod 1 is inserted into the plug groove 61, it is fixed by a tight fit, so as to achieve a stable connection between the handle 6 and the threading main rod 1, and at the same time facilitate postoperative disassembly, cleaning and assembly.

[0035] See Figure 9The handle 6 has a hook 64 mirrored at its tail end. The hook 64 is located on the left and right sides of the tail end of the handle 6, with a symmetrical structure. It is used to provide a temporary hanging function during the process of pulling back the artificial ligament with the guide 4. The movable end of the guide 4 can be hung on the hook 64, which is convenient for adjusting the tension and stabilizing the pulling direction. The outer surface of the handle 6 is provided with an anti-slip strip 63. The anti-slip strip 63 is made of rubber or soft high-friction material molded to enhance the friction when the operator holds it, improve the accuracy and safety of the operation during the operation, and avoid slippage caused by hand sweat or instrument contamination, which would affect the operation effect. Example 2

[0036] See Figure 1 , Figure 4 and Figure 8 A guiding and mating structure for a threading head 2 and a threading main rod 1 includes a guide post 24 and a guide groove 14. The guide post 24 is made of medical-grade stainless steel (model: SUS304), with a length of 18mm and a diameter of 3mm, and is inserted into the positioning hole 13 at the front end of the threading main rod 1. The guide groove 14 is located at both ends on the outer side of the threading main rod 1, with a depth of 2mm and a width of 3.5mm. The locking block 51 is fixed to the bottom of the push head 5, and moves the guide post 24 back and forth by sliding, thereby realizing the axial sliding of the threading head 2.

[0037] In the comparative case, the lack of a guide structure and reliance solely on the interaction between the outer wall of the threading head and the inner cavity of the main rod resulted in uneven sliding and a tendency to deviate. In contrast, this embodiment utilizes guide posts and guide grooves for precise guidance, effectively improving the stability and accuracy of the threading head's movement. Example 3

[0038] See Figures 1 to 5 A locking structure is used to fix the ring end of the artificial ligament. A first locking groove 12 is formed at the front end of the suture main rod 1, with a width of 4mm and a depth of 3mm. A second locking groove 211 is formed on the side wall of the suture head 2 body 21, with the same specifications. The material used is medical-grade polycarbonate (model: PC-110), which has high hardness and moderate elasticity, facilitating insertion and clamping. During the operation, the artificial ligament (model: LARS-Ligament) ring is inserted into the two grooves to form a clamping structure, improving traction stability.

[0039] The comparative case used external clamps for assisted clamping, which not only occupied surgical field space but also made it easy for ligaments to slip due to clamp loosening; this embodiment uses the device structure itself to complete the clamping, which is simpler in structure and more stable in operation. Example 4

[0040] See Figure 6 and Figure 9The head body 21 has a pin hole 23 inside, into which a titanium alloy pin 3 (model: TC4) is inserted, with a diameter of 2.5 mm and a length of 12 mm. Its outer surface has an annular groove 31 with a depth of 0.3 mm to fix the annular head 41. The lead wire 4 is a braided polyester thread (model: ETHIBOND No.2). A retaining plate 32 with a diameter of 5 mm is provided at the tail end of the pin 3 to prevent it from exiting the pin hole 23. This structure can prevent the lead wire from slipping during dynamic pulling.

[0041] The comparative case used a heat-fusion connector to fix the lead wire, which had poor stability due to the heat treatment time and was inconvenient to disassemble. In contrast, the present embodiment has a clear structure, stable connection, and strong replaceability. Example 5

[0042] See Figure 5 The head body 21 has a storage groove 22 at the bottom, which is 12mm long × 4mm wide × 3mm deep. The material is medical polypropylene (model: PP-R), and the inner surface is provided with a guide slope. During the intraoperative threading process, the redundant section of the 4-lead can fall naturally into the storage groove to avoid hanging, tangling and interference with the surgical field.

[0043] In the comparative case, the lead wire is suspended directly outside the head body, which is prone to tangling and forming knots during the pulling process, requiring repeated cleaning operations; this embodiment effectively prevents redundant movement of the lead wire and improves operation efficiency. Example 6

[0044] See Figure 8 and Figure 9 The handle 6 has a plug groove 61 at the end, which is 10mm long and 8mm deep, and plugs into the end of the main rod 1 to form a firm connection; the plug interface is provided with a limiting ridge line and an anti-rotation wedge groove to enhance the reliability of the connection; the material is ABS medical plastic (model: ABS-M90).

[0045] The comparative case uses adhesive to fix the main rod and handle, which is inconvenient to disassemble and cannot be reused after disassembly. In contrast, this embodiment can be quickly disassembled and assembled, meeting the needs of postoperative cleaning and structural maintenance. Example 7

[0046] See Figure 9 The handle 6 has symmetrical hooks 64 on both sides of the tail. The material is silicone (model: LSR9700), which has good elasticity and a bending radius of 5mm. During the operation, the free end of the lead wire 4 can be wrapped around the hook 64 to adjust the traction direction and tension, which is suitable for one-handed operation by the operator.

[0047] In contrast to the previous case, which required an assistant to maintain tension, this embodiment allows the operator to adjust independently, reducing reliance on personnel and improving threading accuracy and ease of operation. Example 8

[0048] See Figure 9 The outer surface of the handle 6 is provided with anti-slip strips 63, with a stripe width of 1.5mm and a spacing of 2mm. They are made of medical TPE soft rubber coating (model: TPE-M75) and have excellent anti-slip performance. During the grip, the friction can be significantly improved to prevent the hand from slipping during the operation and thus reduce the operation accuracy.

[0049] In the comparative case, the handle was made of smooth, hard plastic, which could easily slip and affect accuracy if the gloves became wet during operation; this embodiment has a reasonable structure and effectively ensures safety and accuracy during the operation.

[0050] The working principle of this invention is as follows: During use, the operator holds the handle 6 and guides the threading head 2 through the threading main rod 1 to complete the threading task of the guide wire 4 in the reconstruction of the coracoclavicular ligament.

[0051] In use, one end of the threading head 2 is inserted into the positioning hole 13 of the threading main rod 1 through the guide post 24, and the guide post 24 cooperates with the guide groove 14 to keep the threading head 2 and the threading main rod 1 stably connected. At this time, the push head 5 slides along the threading main rod 1, driving the locking block 51 to move in the guide groove 14, thereby driving the guide post 24 to push the threading head 2 forward or retract, realizing the controllable sliding of the threading head 2 inside the threading main rod 1.

[0052] During the threading process, one end of the lead wire 4 passes through the first lead wire hole 11 and the second lead wire hole 62, passing through the threading main rod 1 and the handle 6, while the other end is connected inside the threading head 2. A pin 3 is provided inside the threading head 2, and the pin 3 has an annular groove 31 for fixing the annular head 41 of the lead wire 4 to prevent it from falling off; at the same time, a retaining plate 32 is provided at the other end of the pin 3 to limit its axial displacement, ensuring that the lead wire 4 is stably fixed in the threading head 2. During the threading process, the lead wire 4 can be stored in the storage groove 22 provided below the head body 21, thus making the threading process smoother.

[0053] When performing artificial ligament pullback, the loops on the artificial ligament can be respectively locked in the first locking groove 12 of the threading main rod 1 and the second locking groove 211 of the threading head 2 to form a stable clamp; then, by pulling back the guide wire 4, the artificial ligament can be smoothly pulled through from below the coracoid process and pulled back to the clavicle foramen.

[0054] To improve ease of operation, the movable end of the lead 4 can be hooked onto the hook 64 at the end of the handle 6 for easy pulling and tension control; the outer side of the handle 6 is equipped with an anti-slip strip 63 to enhance grip stability during surgery and prevent slippage from affecting operational accuracy. At the same time, the handle 6 is connected to the suture main rod 1 through a plug-in structure for easy disassembly and maintenance.

[0055] This suture threader has a simple structure and is easy to operate. It can achieve precise, safe and efficient artificial ligament guidance and threading in coracoclavicular ligament reconstruction surgery, improving intraoperative efficiency and reconstruction quality.

[0056] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
