Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a fiber ring suture device. Background Technology

[0002] Lumbar disc herniation is a syndrome caused by disc degeneration, rupture of the annulus fibrosus, and protrusion of the nucleus pulposus, which irritates or compresses the nerve root. Surgery requires cutting the annulus fibrosus and removing the nucleus pulposus from the rupture site. After the surgery, the incision site of the annulus fibrosus needs to be sutured to reduce the possibility of recurrence of lumbar disc herniation. In related techniques, a disposable annulus fibrosus suture device can be used to suture the annulus fibrosus.

[0003] Application CN119235385A discloses a circular annulus suture device, belonging to the field of medical device technology, which solves the technical problems of long suture time and poor adaptability of existing circular annulus suture devices. It includes a suture needle assembly comprising a puncture element and a clamping seat; the puncture element includes a shuttle and a push rod, a grasping rod, a puncture needle, and a sheath arranged sequentially from the inside out, with the shuttle used to clamp the suture; a suture needle control assembly for guiding the puncture element to drive the suture through a first side of the material to a second side, and then through another location on the second side of the material to the first side; a clamping seat for receiving the shuttle on the second side of the material; and a handle housing for fixing the suture needle assembly and the suture needle control assembly, including a fixing part and a movable part movably connected to the fixing part. This circular annulus suture device can meet more needs and improve suture success rate or shorten suture time.

[0004] The aforementioned results lack an opening adjustment slot for installing the adjustment seat and push block, making it inconvenient for combination installation and push adjustment, resulting in poor adaptability. Furthermore, it is not convenient for directly aligning and clamping the fiber bundle, which is not conducive to replacement and use, and needs to be improved. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: a fiber ring suture device. (See also...) Figure 1 , Figure 3 and Figure 4One end of the handle 1 is equipped with a stop 11, and a connecting tube 12 is fixedly connected to one side of the stop 11. A catheter 13 is fixedly inserted into the inside of the connecting tube 12. A guide head 14 is provided at the end of the catheter 13, and a puncture head 15 is provided at the end of the guide head 14. The catheter 14 can be punctured and inserted into the surgical site to facilitate the insertion of the annulus fibrosus into the interior for suturing. This makes the procedure convenient, stable, and efficient. The other end of the catheter 13 is equipped with a clamping connector 2, which is elastically clamped into the inside of the handle 1. A fiber bundle 21 is slidably connected inside the catheter 13, allowing the fiber bundle 21 to be stored inside the catheter 13. During the surgical procedure, it can be punctured and inserted into the contracted position to bind and suture the annulus fibrosus. This facilitates the operation. The fiber bundle 21 is a disposable consumable, making it easy to replace and adjust. The handle 1 is equipped with a mounting groove 16, and the front end of the mounting groove 16 is equipped with a... The opening adjustment groove 17 can be combined and connected for positioning and sliding adjustment, facilitating telescopic control, ensuring stability and efficiency, and avoiding interference. An adjustment seat 18 is slidably installed inside the mounting groove 16. A push block 19 is provided at the end of the adjustment seat 18, and the push block 19 is slidably installed inside the opening adjustment groove 17. A positioning block 22 is snapped into the inside of the adjustment seat 18, and a clamping hole 23 is provided inside the positioning block 22. One end of the fiber bundle 21 is provided with a bending head 24, which is snapped into the inside of the clamping hole 23. The end of the fiber bundle 21 can be inserted into the clamping hole 23, thereby forming a clamping and positioning by the bending head 24. When the adjustment seat 18 is pushed to move, it can be combined with the positioning block 22 to push the fiber bundle 21 to slide inside the guide tube 13, thereby passing out from the guide head 14. Suturing can be performed through the end of the fiber bundle 21, which is conducive to shrinkage operation and convenient for control.

[0018] Please see Figure 1 and Figure 2 A folding protective cover 25 is fixedly connected to one side of the push block 19. The folding protective cover 25 is slidably connected to the inside of the opening adjustment slot 17. The clamping hole 23 is a right-angle hole and is located inside the adjustment seat 18. One end of the fiber bundle 21 is located inside the handle 1 and is slidably connected to one side of the mounting slot 16. By connecting the folding protective cover through the push block, the position of the opening adjustment slot can be supported and protected, ensuring the stability of use, and will not interfere with the back-and-forth sliding adjustment. It is convenient and efficient. When the push block 19 is manually pushed to move the adjustment seat 18, the folding protective cover 25 can be extended and retracted to isolate and protect the connection position, improve the safety of use, and has high adaptability.

[0019] Please see Figure 1 , Figure 2 and Figure 5The mounting groove 16 has guide grooves 3 on both sides inside, located on both sides of the adjusting seat 18. A U-shaped elastic plate 31 is fixedly connected to the end of the adjusting seat 18. The U-shaped elastic plate 31 is slidably installed inside the mounting groove 16. Limiting teeth 32 are provided at both ends of the U-shaped elastic plate 31, and these limiting teeth 32 are elastically engaged with the inside of the guide grooves 3. By using the guide grooves inside the mounting groove, combined with the U-shaped elastic plate connected to the adjusting seat and the limiting teeth, elastic engagement and limiting can be achieved. During adjustment, it can also assist in guidance and ensure precision. Stable and easy to control the pushing distance, it is stable and easy to use in surgical operations. It is highly adaptable. When the pushing adjustment seat 18 slides and adjusts along the inside of the mounting groove 16, it can move synchronously with the U-shaped elastic plate 31. The limiting teeth 32 on both sides can be elastically connected along the guide tooth groove, so that the position can be slidably adjusted. When pushing stops, the limiting teeth 32 are elastically locked into the guide tooth groove 3 at the corresponding position, which can be combined and positioned to avoid loosening. This is conducive to precise control of the pushing distance, convenient for controlling the insertion depth during surgical suturing, and convenient and stable.
