Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a knot-free medical suture. Background Technology

[0002] No-knot sutures typically incorporate specific stopping components into ordinary sutures. These components prevent suture slippage through interaction with the tissue. These stopping components may include protrusions, barbs, or specially shaped structures on the suture body, as well as stopping wings at the tail of the suture. No-knot sutures are now widely used in various surgical procedures, such as skin suturing, soft tissue suturing, and internal organ suturing. In areas with high tension, such as when suturing muscle layers in abdominal surgery, the stopping structure provides better suture retention.

[0003] Currently, the stop structure at the end of the suture is usually presented as a polygonal prism tail fin, and the device is perpendicular to the suture body. Because the angle at which the suture enters the tissue changes each time during suturing, in certain situations, such as suturing the liver or in confined spaces, the tail fin may not be able to fully adhere to the tissue, easily causing tissue damage at the contact point and cutting / compression injuries to adjacent tissues. Furthermore, existing stop structures cannot adequately align and tighten the tissue at the start of suturing, easily leading to loosening of the suture incision. Currently, in clinical practice, a method of forcefully pulling the suture body is used to manually tighten the suture position, but this increases the risk of the suture body or the connection between the suture body and the stop device breaking. Utility Model Content

[0004] Therefore, this utility model proposes a knotless suture that reduces the risk of tissue deformation and rupture.

[0005] To address the aforementioned technical problems, this utility model provides the following technical solution:

[0006] A medical suture includes: a suture body, the tail end of which is provided with a stop wing, the width of which is greater than the width of the suture body, and the stop wing having at least two openings suitable for the suture body to pass through along the extension direction of the suture body.

[0007] In some embodiments of this utility model, the suture body and the stop wing are integrally formed, and the thickness of the suture body and the stop wing are the same.

[0008] In some embodiments of this utility model, the stop wing includes a first opening and a second opening, with the first opening close to the suture body; in the working state, the suture body passes through the first opening and connects with the tissue to be sutured, and then passes through the second opening to continue connecting with the tissue to be sutured.

[0009] In some embodiments of this utility model, the suture body is provided with spaced-apart spikes along its extension direction, and the ends of the spikes face toward the stop wing.

[0010] In some embodiments of this utility model, the thorn-like protrusions are integrally formed with the suture body and symmetrically arranged on both sides of the suture body in the width direction.

[0011] In some embodiments of this utility model, the spiked protrusions are elastically deformable. When the suture body passes through the opening of the stop wing, the spiked protrusions are compressed after being squeezed and return to their initial state after passing through the opening.

[0012] In some embodiments of this utility model, in the working state, the free end of the spike-like protrusion can abut against the outer surface of the opening of the stop wing.

[0013] In some embodiments of this invention, the thorn-like protrusions have the same thickness as the suture body.

[0014] In some embodiments of this invention, the width of the stop wing is greater than the distance between the ends of the symmetrical spikes.

[0015] In some embodiments of this invention, the distance between adjacent spikes along the extension direction of the suture body is greater than the thickness of the stop wing.

[0016] The technical solution of this utility model has the following technical advantages over the prior art:

[0017] The medical suture provided by this invention features a wide stop wing. During tissue suturing, the wing abuts against the tissue to be sutured, and the suture body is first passed through the opening on the stop wing before connecting to the tissue. This ensures complete contact between the stop wing and the tissue, preventing tail warping caused by needle insertion angle issues. It also allows for a more even distribution of force on the suture across the stop wing, spreading the force over a larger area. This force dispersion reduces stress on the tissue at the suture site, minimizing the risk of tissue deformation and rupture. Simultaneously, the stop wing's close contact with the tissue increases the contact area, providing more stable support and fixation, creating a favorable environment for tissue healing.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1-5The image shows a specific embodiment of the medical suture provided by this utility model, which is used in surgical procedures to achieve tissue suturing.

[0029] like Figure 1 As shown, the medical suture includes a suture body 1, and a stop flap 2 is provided at the tail end of the suture body 1. The width of the stop flap 2 is greater than the width of the suture body 1, and the stop flap 2 extends along the extension direction of the suture body 1 (see [reference]). Figure 1 The suture body 1 has at least two openings on the suture (in the direction indicated by arrow X).

[0030] Traditional sutures have a small contact area with tissue, leading to concentrated local pressure and significant cutting and compression effects on the tissue. Reducing these cutting and compression effects is particularly important for fragile tissues, as damage to these tissues can result in severe functional impairment. The medical suture described in this embodiment features a wider stop wing 2. During use, the stop wing 2 is brought into contact with the tissue A to be sutured, while the suture body 1 passes through an opening in the wing before connecting to the tissue A. This ensures complete contact between the stop wing 2 and the tissue, preventing tail warping caused by needle insertion angle issues. It also allows for a more even distribution of force on the stop wing 2, dispersing the force over a larger area. This force dispersion reduces stress at the suture site, minimizing the risk of tissue deformation and rupture. Simultaneously, the stop wing 2's close contact with the tissue increases the contact area, providing more stable support and fixation, creating a favorable environment for tissue healing.

[0031] Specifically, the suture body 1 and the stop wing 2 are integrally formed to reduce processing difficulty and assembly steps. Simultaneously, the suture body 1 and the stop wing 2 have the same thickness, ensuring the uniformity of the suture under stress, improving overall stress performance, and making the suture more stable and less prone to breakage during use. More specifically, the suture body 1 is constructed as a linear structure with a roughly rectangular cross-section, while the stop wing 2 is constructed as a sheet structure with a roughly rectangular cross-section. The sheet shape can be rectangular, polygonal, circular, or elliptical.

[0032] Specifically, such as Figure 1 , Figure 4 As shown, the stop wing 2 includes a first opening 21 and a second opening 22, with the first opening 21 close to the suture body 1; see also Figure 4As shown, during tissue suturing, the first surface of the stop wing 2 is first placed against the surface of the tissue A to be sutured. The end of the suture body 1 is then inserted through the first hole 21 along the second surface of the stop wing 2, and then inserted into the tissue A to be sutured and connected to it. Finally, the suture is inserted through the second hole 22 along the first surface of the stop wing 2 and connected to the tissue A again. The aforementioned double-hole design of the stop wing 2 allows the suture to pass through pre-designed holes on the stop wing 2, further securing the stop wing 2 to ensure complete adhesion to the tissue and preventing warping of the tail wing due to the needle insertion angle. Complete adhesion to the tissue also prevents the warped stop wing 2 from cutting or damaging adjacent tissues, reducing patient discomfort and pain, and avoiding secondary injury. Because the stop wing 2 adheres better to the tissue, the surgeon does not need to spend excessive time adjusting it during suturing, thus reducing surgical time.

[0033] Specifically, in one alternative implementation, such as Figure 1 As shown, the suture body 1 has spaced-apart spikes 3 along its extension direction, with the ends of the spikes 3 pointing towards the stop wing 2. By providing the spikes 3, the suture body 1 and the tissue A to be sutured are tightly and reliably connected during tissue suturing, preventing relative movement between them. The surgeon can perform the suturing operation with greater confidence, without worrying about the suture loosening, thus avoiding the need for forceful suture pulling. Due to the suture's anti-retraction function, the surgeon does not need to frequently adjust the suture position or worry about loose sutures during the suturing process, thus greatly saving operation time. This reduces surgeon fatigue and improves the quality and precision of the surgery.

[0034] More specifically, in one optional embodiment, the spiked protrusions 3 are integrally formed with the suture body 1 and symmetrically disposed in the width direction of the suture body 1 (see...). Figure 1 The suture is positioned on both sides (in the direction indicated by the middle arrow Y) to ensure even force distribution on the suture, making it more stable in the tissue and preventing suture displacement or excessive local stress due to uneven force distribution, thus further improving the suturing effect.

[0035] Specifically, the spiked protrusion 3 is made of an elastically deformable medical material. When the suture body 1 passes through the orifice of the stop wing 2, the spiked protrusion 3 is compressed after being squeezed and returns to its initial state after passing through the orifice. In the working state (i.e., when the suture is sutured to the tissue A to be sutured), the free end of the spiked protrusion 3 can abut against the outer surface of the orifice of the stop wing 2. The cooperation between the spiked protrusion 3 and the stop wing 2 can achieve a better anti-reverse effect, ensuring that the tissue can be tightly fixed together in the early stage of suturing. This prevents the suture from moving backward in the tissue, thereby maintaining the stability of the suture.

[0036] Specifically, in one optional embodiment, the thorn-like protrusions 3 have the same thickness as the suture body 1, ensuring the overall uniformity of the suture. When subjected to force, each part bears the same stress, making it less likely for weak points to appear, thus improving the strength and durability of the suture.

[0037] Specifically, refer to Figure 1 As shown, the width D of the stop wing 2 is greater than the distance L between the ends of the symmetrical spikes 3. This design allows the stop wing 2 to better disperse the force and at the same time provide stable support for the spikes 3, preventing the spikes 3 from being excessively deformed or damaged when subjected to force, thus ensuring the anti-reverse effect and the stability of the stitching.

[0038] When setting the spiked protrusions 3, ensure that the distance between adjacent spiked protrusions 3 along the extension direction of the suture body 1 is greater than the thickness of the stop wing 2. This arrangement allows adjacent spiked protrusions 3 to be located on the upper and lower sides of the stop wing 2, ensuring sufficient space near the stop wing 2 to accommodate the spiked protrusions 3, guaranteeing that the spiked protrusions 3 can function properly to stop backward movement without affecting the function of the stop wing 2. Simultaneously, appropriate spacing also prevents adjacent spiked protrusions 3 from interfering with each other.

[0039] In one optional embodiment, the first opening 21 and the second opening 22 of the stop wing 2 are constructed as conical holes. The first opening 21 is formed as a conical hole that gradually expands from the first surface to the second surface of the stop wing 2, while the second opening 22 is formed as a conical hole that gradually narrows from the first surface to the second surface of the stop wing 2. This structure facilitates the insertion of the suture body 1 with the barbed protrusions 3, and at the same time, it enables the barbed protrusions 3 to reliably abut against the surface of the stop wing 2 after they have passed through.

[0040] When using the aforementioned medical sutures for tissue suturing, the surgeon first passes the suture body 1 through the first opening 21 of the stop wing 2, and then connects it to the tissue A to be sutured. Next, the suture body 1 is passed through the second opening 22 and connected to the tissue A again. At this point, the free end of the spiked protrusion 3 abuts against the outer surface of the opening of the stop wing 2, preventing the suture from regressing and moving backward within the tissue. Throughout the process, the stop wing 2 effectively disperses force, reduces tissue stress, and prevents tissue deformation and rupture. Simultaneously, the double-hole design of the wing ensures complete adhesion to the tissue, reducing tissue damage caused by needle insertion angle issues, saving surgical time, and improving surgical quality.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
