Description

Technical Field

[0001] This utility model belongs to the field of medical suture technology, specifically relating to a non-absorbable suture woven from silk threads. Background Technology

[0002] In the medical field, sutures are divided into two main categories: absorbable and non-absorbable. Non-absorbable sutures are not absorbed by the body, so they are suitable for tissues requiring long-term support or permanent closure, such as the repair of joint capsules, tendons, blood vessels, and nerves. Silk sutures, as a traditional non-absorbable suture material, have good tensile strength and smoothness, are easy to pass through tissues, and cause less irritation to tissues.

[0003] The existing ones are based on single-thread sutures, but they have poor support and tension, low tensile strength, are easy to break, and cannot effectively close the wound securely. This can easily cause the wound to reopen, requiring subsequent patients to have it re-stitched, which wastes time and can leave obvious marks. Utility Model Content

[0004] The purpose of this invention is to provide a non-absorbable suture woven from silk threads, which aims to solve the problems of existing technologies that use single threads as a basis, but have poor support and tension capabilities, low tensile strength, are prone to breakage, cannot effectively close the wound, and are prone to secondary dehiscence of the wound, requiring subsequent suturing by the patient, wasting time, and easily leaving obvious marks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A non-absorbent sewing thread woven from silk threads, comprising:

[0007] sutures;

[0008] The suture includes collagen suture, polypropylene suture, polyester suture, polyurea suture, polytetrafluoroethylene suture, and stainless steel wire suture, and the collagen suture, polypropylene suture, polyester suture, polytetrafluoroethylene suture, polyurea suture, and stainless steel wire suture are designed to be cross-wound.

[0009] As a preferred embodiment of this utility model, the surface of the suture is provided with multiple sets of nylon sutures.

[0010] As a preferred embodiment of this utility model, the spacing between each group of nylon stitches is 5cm.

[0011] As a preferred embodiment of this invention, the stainless steel wire suture is used in surgeries requiring high strength and durability.

[0012] In a preferred embodiment of this invention, the stainless steel wire stitching is located at the center.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this solution, various suture materials such as collagen sutures, polypropylene sutures, polyester sutures, polyurea sutures, polytetrafluoroethylene sutures, and stainless steel wire sutures are combined in a cross-wrap manner to form a composite suture. This design can significantly improve the overall strength and abrasion resistance of the suture, ensuring that it is not easily broken under high tension surgical conditions and providing a more reliable tissue fixation effect. The stainless steel wire suture is placed in the center position, which not only enhances the core strength of the suture, but also provides additional durability and corrosion resistance due to its metallic properties, making it very suitable for surgical sites that require long-term support or frequent contact with body fluids.

[0015] 2. In this design, multiple sets of nylon sutures on the suture surface further optimize suturing performance. The addition of nylon sutures not only increases the flexibility of the sutures, making them easier for doctors to handle, but also reduces damage to surrounding tissues during suturing, promoting wound healing. The precise spacing between each set of nylon sutures is set at 5cm. This design ensures uniform tension distribution during suturing, avoiding excessive local stretching, thereby reducing the risk of postoperative complications and accelerating the patient's recovery.

[0020] 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.

[0021] Example 1

[0022] Please see Figures 1-2 The present invention provides the following technical solution:

[0023] A non-absorbent sewing thread woven from silk threads, comprising:

[0024] 1 suture;

[0025] The suture 1 includes collagen suture 101, polypropylene suture 102, polyester suture 103, polyurea suture 104, polytetrafluoroethylene suture 105, and stainless steel wire suture 106. The collagen suture 101, polypropylene suture 102, polyester suture 103, polytetrafluoroethylene suture 105, polyurea suture 104, and stainless steel wire suture 106 are designed with a cross-wound pattern.

[0026] In a specific embodiment of this utility model, collagen suture (101) provides biocompatibility and a certain degree of flexibility; polypropylene suture (102) enhances the abrasion resistance and tensile strength of the suture; polyester suture (103) provides additional strength and durability; polyurea suture (104) increases the flexibility and elasticity of the suture; polytetrafluoroethylene suture (105) reduces friction between the suture and tissue and improves sliding properties; and stainless steel wire suture (106) strengthens the suture structure and increases overall strength. The stainless steel wire suture (106) forms the main strength structure. Various suture materials are pre-treated to ensure their surfaces are clean and smooth. These suture materials are then woven together using a precision braiding machine according to a specific cross-winding design to form a composite suture structure. Tension is controlled during the weaving process to ensure that each material is evenly distributed and tightly bonded, preventing breakage during surgery while maintaining high strength during use to prevent wound re-opening and protect personnel safety.

[0027] Please refer to the details. Figures 1-2 The surface of the suture 1 is provided with multiple sets of nylon sutures 2.

[0028] In this embodiment: Nylon thread 2 has excellent strength and abrasion resistance, which can improve the overall durability of the thread. It also provides better knot holding force, and once knotted, the thread is less likely to come loose. At the same time, Nylon thread 2 is bound to the surface of various composite threads to strengthen their strength and form an additional protective layer.

[0029] Please refer to the details. Figures 1-2 The spacing between each set of nylon stitches is 5cm.

[0030] In this embodiment: the 5 cm interval allows the suture to provide sufficient strength and abrasion resistance without sacrificing flexibility, which helps the surgeon to manipulate the suture more easily during surgery, while ensuring the smoothness of the suture as it slides through the tissue.

[0031] Please refer to the details. Figures 1-2 Stainless steel wire suture 106 is used in surgeries requiring high strength and durability.

[0032] In this embodiment: In heart valve repair or coronary artery bypass grafting surgery, sutures are required to provide long-term support. The high strength of stainless steel wire suture 106 can prevent breakage. For nerve tissue repair that requires delicate operation and long-term stability, stainless steel wire suture 106 is one of the preferred options.

[0033] Please refer to the details. Figures 1-2 The stainless steel wire stitching 106 is located in the center.

[0034] In this embodiment, the stainless steel wire suture 106 is embedded in the center of the suture 1 to provide core support for the entire suture by utilizing its high strength and durability. The stainless steel wire suture 106 in the center can effectively disperse the tension during suturing and improve the overall strength of the suture. As a central reinforcing element, the stainless steel wire suture 106 can help the suture maintain its shape and function in complex surgical environments and extend its effective service life in the body.

[0035] The working principle and usage process of this utility model are as follows: Using a precision braiding machine, raw protein sutures 101, polypropylene sutures 102, polyester sutures 103, polyurea sutures 104, polytetrafluoroethylene sutures 105, and stainless steel wire sutures 106 are braided together according to a specific cross-winding design to form a composite suture structure. Tension is controlled during the braiding process to ensure that each material is evenly distributed and tightly bonded. After the sutures are completed, they undergo high-temperature sterilization to eliminate any potential microbial contamination and prevent breakage during surgery. Simultaneously, the sutures maintain high strength during use, preventing wound re-opening and protecting personnel safety.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
