Description

Technical Field

[0001] This utility model relates to the field of suture development technology, specifically to a developable marking suture structure. Background Technology

[0002] With the continuous development of medical technology, the requirements for surgical precision and safety are becoming increasingly stringent. In the modern medical field, arterial stent surgery is one of the important means of treating cardiovascular diseases. Currently, branch vessel technology is mainly achieved by combining in vivo or external fenestration techniques on large vessel stents with branch stent placement. When X-ray imaging is required, fenestration is performed on the large vessel stent, and a metal coil is sewn at the fenestration site for marking. The pre-fenestrated large vessel stent is then reloaded into the delivery device and inserted into the large vessel for fluoroscopic positioning and release to complete the surgery. However, the traditional method of sewing metal coils not only increases the additional economic burden and wastes medical resources, but also makes it difficult to reload the large stent into the delivery device because the volume of the stent fenestration site increases after sewing the coils. Some pre-fenestrated large stents may experience ectopic embolism due to the unreliable sewing of the coils during or after the operation, seriously endangering the patient's life. On the other hand, the traditional suture connection method may waste sutures during cutting and lacks flexibility, making it difficult to quickly change sutures of different thicknesses according to the needs of different surgical scenarios. This limits its application range to a certain extent and may also increase the consumption of medical resources. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a visible marking suture structure, comprising: a needle structure; a suture structure, wherein the outer wall of the suture structure is slidably connected to the inner wall of the needle structure; the suture structure includes a suture thread, and a winding thread is fixedly connected to the outer wall of the suture thread; the suture thread includes a polypropylene suture thread, and the polypropylene suture thread is a single-strand suture thread made by polymerizing propylene, possessing good strength, smooth and soft texture, and good biocompatibility; the inner wall of the polypropylene suture thread is fixedly connected to a polylactic acid suture thread, and the polylactic acid suture thread is a polymer obtained by fermentation from renewable resources such as corn and potatoes, exhibiting good affinity with human tissue. It is non-invasive and will not cause obvious inflammatory or foreign body reactions. The inner wall of the polylactic acid suture is fixedly connected to a radiopaque suture, and the interior of the radiopaque suture is composed of substances such as barium and iodine that are X-ray impermeable. Barium is a heavy metal element with a high atomic number. In X-ray and other imaging examinations, substances with higher atomic numbers have a stronger ability to absorb X-rays, and their absorption of X-rays differs greatly from that of surrounding human tissues. When X-rays pass through the human body, the barium-containing suture will block more X-rays, appearing as an image different from the surrounding tissues on imaging equipment. These substances can be radiopaque under X-ray irradiation, allowing doctors to clearly see the position of the suture during or after surgery.

[0004] Preferably, the outer walls of the polypropylene suture, polylactic acid suture, and developing suture are fixedly connected to the outer walls of the winding thread. The winding thread drives the suture to connect and fix with the needle structure. Usually, the part below the connection between the needle structure and the suture structure is cut off and removed from the support along with the needle structure. This avoids the waste caused by cutting the suture directly wrapped around the needle structure. The winding thread is a common suture and has a low cost.

[0005] Preferably, the suture needle structure includes a hook needle body, and a circular needle tip is fixedly connected to the outer wall of the top of the hook needle body. The tip of the circular needle tip is relatively rounded, which causes less damage to the stent structure and is suitable for suturing artificial blood vessels and vascular stents. A suture needle tail is fixedly connected to the outer wall of the hook needle body on the side away from the circular needle tip.

[0006] Preferably, the outer wall of the suture needle tail is provided with a positioning hole, through which it is connected and fixed to the suture structure.

[0007] Preferably, the outer wall of the winding thread is slidably connected to the inner wall of the positioning hole, and the suture thread is connected and fixed to the suture needle tail by passing the winding thread through the positioning hole and then winding and knotting it.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model, through its suture structure, comprises polypropylene suture, polylactic acid suture, and radiopaque suture. The polypropylene suture boasts high strength and biocompatibility; the polylactic acid suture, derived from renewable resources, is biocompatible, reducing inflammation and foreign body reactions. This combination provides patients with a more comfortable postoperative recovery experience and lowers the likelihood of adverse reactions caused by the suture. The radiopaque suture contains X-ray-impermeable substances such as barium and iodine, allowing it to be visualized under X-ray irradiation. This enables surgeons to accurately locate the suture during surgery, ensuring suturing accuracy. Postoperatively, it facilitates observation of the suture, allowing for timely detection of potential problems and providing a powerful monitoring tool for patient recovery. After surgery, the suture can be cut below the connection point between the needle and the suture structure, removing the suture along with the needle, avoiding the waste caused by cutting the suture directly wrapped around the needle. Using ordinary suture as the wrapping thread is less costly, effectively reducing medical costs without compromising surgical quality. This connection method allows for easy replacement of sutures of different thicknesses as needed, enhancing the suture structure's applicability and meeting the requirements of various surgical scenarios.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0016] Example:

[0017] Please see Figure 1 - Figure 4This utility model provides a technical solution: a visible marking suture structure, comprising: a needle structure 1; a suture structure 2, the outer wall of the suture structure 2 being slidably connected to the inner wall of the needle structure 1; the suture structure 2 including a suture 21, the outer wall of which is fixedly connected to a winding thread 22; the suture 21 including a polypropylene suture 211, which is a single-strand suture made by polymerizing propylene, possessing good strength, smooth and soft texture, and good biocompatibility; the inner wall of the polypropylene suture 211 is fixedly connected to a polylactic acid suture 212, which is a polymer obtained by fermentation from renewable resources such as corn and potatoes, possessing good affinity with human tissue and not causing obvious... To prevent obvious inflammatory and foreign body reactions, the inner wall of the polylactic acid suture 212 is fixedly connected to a radiopaque suture 213. The interior of the radiopaque suture 213 is composed of substances such as barium and iodine that are X-ray impermeable. Barium is a heavy metal element with a high atomic number. In X-ray and other imaging examinations, substances with higher atomic numbers have a stronger ability to absorb X-rays, and their absorption of X-rays differs greatly from that of surrounding human tissues. When X-rays pass through the human body, the barium-containing suture blocks more X-rays, which appears as a different image from the surrounding tissue on the imaging device, thus enabling the radiopaque suture 213 to be clearly seen by doctors during or after surgery.

[0018] The outer walls of the polypropylene suture 211, polylactic acid suture 212, and developing suture 213 are fixedly connected to the outer wall of the wrapping thread 22. The wrapping thread 22 drives the suture 21 to connect and fix to the needle structure 1. Usually, the part below the connection between the needle structure 1 and the thread structure 2 is cut off and taken out of the body together with the needle structure 1. To avoid the waste caused by cutting the suture 21 directly wrapped and connected to the needle structure 1, the wrapping thread 22 is used for connection. The wrapping thread 22 is a common suture and has a low cost.

[0019] The suture needle structure 1 includes a hook needle body 11, with a round needle tip 12 fixedly connected to the outer wall of the top of the hook needle body 11. The tip of the round needle tip 12 is relatively rounded, which causes less damage to the stent structure and is suitable for suturing artificial blood vessels and vascular stents. A suture needle tail 13 is fixedly connected to the outer wall of the hook needle body 11 on the side away from the round needle tip 12.

[0020] The outer wall of the suture needle tail 13 is provided with a positioning hole 14, which is used to connect and fix it to the thread structure 2.

[0021] The outer wall of the wrapping thread 22 is slidably connected to the inner wall of the positioning hole 14. The suture thread 21 is connected and fixed to the suture needle tail 13 by passing the wrapping thread 22 through the positioning hole 14 and then wrapping and knotting it.

[0022] Working principle: The hook needle body 11 in the suture needle structure 1 passes through the round needle tip 12 at the top. Due to the relatively rounded needle tip, it causes less damage to the stent structure and is suitable for suturing artificial blood vessels and vascular stents. The outer wall of the suture needle tail 13 of the suture needle structure 1 is provided with a positioning hole 14.

[0023] The suture 21 in the suture structure 2 is composed of polypropylene suture 211, polylactic acid suture 212, and radiopaque suture 213. The polypropylene suture 211 has good strength, is smooth and soft, and has good biocompatibility. The polylactic acid suture 212 is made of polymers obtained by fermentation from renewable resources such as corn and potatoes, and has good affinity with human tissue, and will not cause obvious inflammatory or foreign body reactions. The radiopaque suture 213 is composed of substances such as barium and iodine that are X-ray impermeable, and can be visualized under X-ray irradiation, making it convenient for doctors to clearly see the position of the suture 21 during or after surgery.

[0024] In use, the wrapping thread 22 is passed through the positioning hole 14 of the needle structure 1 and then wrapped and knotted to connect and fix the suture thread 21 to the needle tail 13. After the sewing operation is completed, the area below the connection between the needle structure 1 and the thread structure 2 is usually cut off and removed from the body along with the needle structure 1. This avoids the waste caused by cutting the suture thread 21 directly wrapped and connected to the needle structure 1. The wrapping thread 22 is used, and it is a common suture thread with low cost. This design not only meets the sewing requirements but also realizes the function of being visible, while reducing costs and making it easy to change sutures of different thicknesses.

[0025] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
