TECHNICAL FIELD

[0001] The present application relates to the medical suture technical field, specifically to a knot-free special-shaped suture. BACKGROUND

[0002] The surgical suture refers to a special thread used for hemostasis and tissue suture in surgical operation or trauma treatment, which is divided into absorbable thread and non-absorbable thread. The traditional suture is knotted at the thread head after suture, which is not only time-consuming and laborious, but also easy to cause inflammation and complications at the knotted thread head. Therefore, a knot-free special-shaped suture is needed.

[0003] In the prior art, a knot-free special-shaped suture is disclosed in Chinese patent application CN108158619 A, which mainly comprises a straight needle, a bent needle, a special-shaped thread and a barb. The straight needle and the bent needle are connected by the special-shaped thread, the bent needle is firmly connected to the special-shaped thread by the bent needle riveting, the two needle heads of the straight needle are needle tip-shaped, the straight needle left needle tip head and the straight needle right needle tip head are arranged, the straight needle middle thread hole is arranged on the middle cylindrical surface of the straight needle, and the barb with a 360° angle is arranged on the special-shaped thread. The suture wound is small, the aesthetic degree is high, the cosmetic surgery effect is good, the knot is free, and the suture is free. Meanwhile, the two needle heads of the straight needle can be used for suture on both sides, which avoids the defects of traditional suture, such as scarring and poor aesthetics caused by knotting and fixing after suture.

[0004] However, in the prior art, the barb is often used to pierce the human skin, so that the suture is embedded in the wound, thereby achieving the effect of not needing knotting. However, the barb on the suture is relatively soft, which cannot guarantee that the barb is completely embedded in the wound, and the fixing effect of the suture is poor, which may cause the suture to burst open. SUMMARY

[0005] The present application aims to provide a knot-free special-shaped suture to solve the problem that the barb is often used to pierce the human skin, so that the suture is embedded in the wound, thereby achieving the effect of not needing knotting. However, the barb on the suture is relatively soft, which cannot guarantee that the barb is completely embedded in the wound, and the fixing effect of the suture is poor, which may cause the suture to burst open.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a knot-free special-shaped suture, comprising a suture body, wherein one end of the outer wall of the suture body is provided with a needle head mechanism.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] Reference Figures 1-7 As shown: A knotless irregular suture includes a suture body 1, and a needle mechanism 2 is provided at one end of the outer wall of the suture body 1;

[0032] The suture body 1 includes a suture 101. A first limiting ball 102 is provided at one end of the outer wall of the suture 101. A second limiting ball 103 is provided at the top of the first limiting ball 102. A first fixing cylinder 104 is provided on the inner surface wall of the first limiting ball 102. A first plug 105 is provided on the inner surface wall of the second limiting ball 103. The first plug 105 is movably inserted into the inner surface wall of the first fixing cylinder 104.

[0033] Reference Figures 1-7 As shown: The outer wall of the suture 101 is provided with a mesh 106. The suture 101 is a hollow structure, and a layer of wound healing aid can be coated inside the suture 101, thereby accelerating the wound healing rate.

[0034] Reference Figures 1-7 As shown: Suture 101 is woven from pure natural collagen material. Pure natural collagen material has the characteristics of complete absorption, high tensile strength, good biocompatibility, and promotion of cell growth. Depending on the thickness of the thread, it is generally completely absorbed in 8-15 days, and the absorption is stable and reliable with no obvious individual differences.

[0035] Reference Figures 1-5 As shown: Mesh 106 is formed into a tube by a mesh material, or by weaving or knitting pure natural collagen material into a tube, or by weaving or knitting pure natural collagen material into a flat sheet and then shaping the flat sheet into a tube. Mesh 106 facilitates and allows tissue to enter the center of suture 101 and become integrated after being introduced into the body, thereby preventing suture 101 from being torn and improving biocompatibility.

[0036] Reference Figures 1-5 As shown: A set of pills 107 are provided inside the suture 101. The outer wall of the set of pills 107 is provided with two barbs 108, and each barb 108 protrudes from the gap of the mesh 106. The barbs 108 can be completely embedded in the wound, which greatly increases the firmness between the suture 101 and the wound.

[0037] ReferenceFigures 1-5 As shown: Each pill 107 and barb 108 is made of pure natural collagen material. Because each pill 107 and barb 108 is made of pure natural collagen material, it can be easily absorbed and prevents the need for suture removal.

[0038] Reference Figures 1-5 As shown: The outer wall of the suture 101 is provided with a set of scale lines 109, and each scale line 109 is made of easily absorbable material. The scale lines 109 make it easy for the doctor to pass through the suture 101 of any length.

[0039] Reference Figures 1-5 As shown: The first limiting ball 102 and the second limiting ball 103 are both made of pure natural collagen material. Since the first limiting ball 102 and the second limiting ball 103 are both made of pure natural collagen material, they can be easily absorbed and prevent secondary damage caused by suture removal.

[0040] Reference Figure 1 , Figure 2 and Figure 6 , Figure 7 As shown: The needle mechanism 2 includes a needle 201. A first fixing ring 202 is fixedly installed on one side of the outer wall of the needle 201. A set of second fixing cylinders 203 are fixedly installed on the inner surface of the first fixing ring 202. A second fixing ring 204 is provided on the top of the first fixing ring 202. A set of second plugs 205 are fixedly installed on the inner surface of the second fixing ring 204. Each second plug 205 is movably inserted into the inner surface of each second fixing cylinder 203. The suture 101 can be placed in the first fixing ring 202, and then the second plugs 205 are inserted into the second fixing cylinders 203, so that the suture 101 can be fixed in the needle 201.

[0041] Reference Figures 1-3 As shown: One end of the outer wall of the suture 101 is movably inserted between the inner surface walls of the first fixing ring 202 and the second fixing ring 204.

[0042] The usage and working principle of this device are as follows: First, place the suture 101 inside the first fixing ring 202. Then, insert the second plug 205 through the suture 101 into the second fixing cylinder 203, thereby fixing the second fixing ring 204 to the top of the first fixing ring 202. This secures the suture 101 within the needle 201. The detachable needle 201 structure facilitates quick assembly and disassembly during suturing, significantly improving wound suturing efficiency. During suturing, first place the suture 101... 1. A layer of wound-healing medication is applied to the surface. Because suture 101 has a mesh structure, the medication can adhere well to its surface. The needle 201 passes through the wound, and the suture 101 sutures the wound. Suture 101 is made of pure natural collagen material and has a mesh structure. This mesh structure facilitates tissue entry into the center of suture 101 after introduction into the body, forming an integrated structure. This prevents suture 101 from tearing and improves biocompatibility. Simultaneously, medication can be applied to the center of the suture to aid wound healing. The medication is used to accelerate wound healing. The mesh structure 106 has a certain degree of elasticity; when the wound swells, the suture 101 can stretch according to the wound tension, preventing it from breaking. Because the beginning of the suture 101 is fixed with a first limiting ball 102 and a second limiting ball 103, the suture end can be secured. Therefore, it prevents the suture end from slipping off the wound without needing to tie a knot. Additionally, the suture 101 contains multiple pills 107, and the barbs 108 attached to the pills 107 can... The suture 101 is embedded within the wound, increasing the strength between the suture and the wound. Furthermore, the suture 101, the first limiting ball 102, the second limiting ball 103, and the pill 107 are all woven from pure natural collagen material. Pure natural collagen material is characterized by complete absorption, high tensile strength, good biocompatibility, and promotion of cell growth. Depending on the thickness of the suture, it is generally completely absorbed in 8-15 days, and the absorption is stable and reliable with no significant individual differences. Therefore, it can be easily absorbed, preventing secondary damage caused by suture removal. In summary, this solves the problems raised in the background above.

[0043] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
