Description

Technical Field

[0001] This utility model relates to the field of wound suturing, specifically to an intermittent barbed suture and an intermittent barbed suture assembly. Background Technology

[0002] In the field of surgical suturing, traditional sutures rely on knots to secure the ends of the sutures and close the wound. However, the presence of knots can lead to several problems: First, the risk of knot loosening is high, especially in frequently moving wound sites (such as joints and tendons), which can easily cause wound dehiscence or secondary suturing; second, the end of the suture can form a foreign body protrusion that may compress surrounding tissues or irritate the skin, increasing the probability of infection; in addition, the complex knot-tying process prolongs the operation time.

[0003] To overcome the aforementioned shortcomings, barbed sutures were developed. These sutures feature barbs on their surface, which, once embedded in the tissue, provide anchoring force through mechanical interlocking with the surrounding tissue, eliminating the need for knot fixation. This technique significantly simplifies the suturing process, reduces knot-related complications, and improves the uniformity of wound closure.

[0004] However, with existing barbed sutures, the barbs usually cover the entire length of the suture. When the suture passes through the skin surface, the exposed barbs may directly compress or puncture the epidermal tissue, especially in suture areas with high tension (such as abdominal incisions or areas of movement), leading to local microtrauma, inflammatory reactions, or even epidermal necrosis, forming "suture marks" or secondary wounds. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the defects of the prior art and provide an intermittent barbed suture that can ensure that the exposed part of the barbed suture outside the skin is at least mostly smooth, thereby reducing the damage to the skin at the suture site.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a spaced-out barbed suture, comprising a plurality of barbed segments and a plurality of smooth segments spaced apart along the extension direction; wherein,

[0007] The lengths of the barbed segment and the smooth segment are configured such that, after the wound is sutured, at least the middle portion of the barbed segment is buried under the skin, and at least the middle portion of the smooth segment is exposed outside the skin.

[0008] Furthermore, to reduce the difficulty of suturing, the lengths of the barb segment and the smooth segment are configured such that, after suturing the wound, the barb segment is completely buried under the skin, and at least one end of the two ends of the smooth segment is buried under the skin.

[0009] Furthermore, to reduce the difficulty of suturing, the lengths of the barbed segment and the smooth segment are configured such that, after suturing the wound, at least one end of the two ends of the barbed segment is exposed outside the skin, and the smooth segment is completely exposed outside the skin.

[0010] Furthermore, the lengths of the barb segment and the smooth segment are configured such that, after the wound is sutured, the barb segment is completely embedded in the skin, and the smooth segment is completely exposed outside the skin.

[0011] Furthermore, to reduce the pressure of the sutures on the wound, the middle part of the smooth section is widened.

[0012] Furthermore, each barb segment has multiple barbs, which are fishbone-shaped, spiky, or triangular.

[0013] Furthermore, in the case where the barbs are triangular:

[0014] Multiple barbs in each barb segment are arranged in a rotating manner along the extension direction of the barb segment;

[0015] Or, multiple barbs in each barb segment are arranged on one side along the extension direction of the barb segment.

[0016] This utility model also relates to an intermittent barbed suture assembly, including intermittent barbed sutures.

[0017] Furthermore, the intermittent barbed suture assembly also includes a suture needle and an anti-detachment stop, wherein the suture needle is connected to the beginning end of the intermittent barbed suture and the anti-detachment stop is connected to the end end of the intermittent barbed suture.

[0018] Furthermore, the spaced barbed suture assembly also includes two suture needles, one of which is connected to the beginning of the spaced barbed suture and the other of which is connected to the end of the spaced barbed suture.

[0019] By adopting the above technical solution, this utility model sets the suture line into multiple barbed segments and multiple smooth segments spaced apart, and sets the length of a single barbed segment to be approximately equal to (or slightly greater than, or slightly less than) the distance of a single needle suture. This ensures that after suturing, most or all of the smooth segment 2 is exposed outside the skin, thereby avoiding local micro-trauma, inflammatory reaction or even epidermal necrosis caused by a large number of barbs contacting and pressing the skin, thus reducing the patient's discomfort and facilitating rapid wound healing.

[0024] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] like Figures 1 to 3 As shown, a barbed suture includes multiple barbed segments 1 and multiple smooth segments 2 spaced apart along its extension direction; wherein,

[0026] The lengths of the barbed segment 1 and the smooth segment 2 are configured such that, after the wound is sutured, at least the middle portion of the barbed segment 1 is buried under the skin, and at least the middle portion of the smooth segment 2 is exposed outside the skin.

[0027] Specifically, in this embodiment, the suture is configured with multiple barbed segments 1 and multiple smooth segments 2 spaced apart, and the length of a single barbed segment 1 is set to be approximately equal to (or slightly greater than, or slightly less than) the distance of a single needle suture. This ensures that after suturing, most or all of the smooth segments 2 are exposed outside the skin, thereby avoiding local micro-trauma, inflammatory reactions, or even epidermal necrosis caused by a large number of barbs 11 contacting and pressing on the skin. This reduces the patient's discomfort and facilitates rapid wound healing.

[0028] Among them, there are various configurations of the lengths of the barb segment 1 and the smooth segment 2, provided that at least the middle part of the barb segment 1 is buried under the skin and at least the middle part of the smooth segment 2 is exposed outside the skin.

[0029] The first type, such as Figure 1 As shown, after suturing the wound, the barb segment 1 is completely embedded in the skin, while the smooth segment 2 is completely exposed outside the skin. That is, the length of a single barb segment 1 is exactly the same as the suture distance of a single needle. This situation requires a high level of suturing skill from the operator.

[0030] The second type, such as Figure 2 As shown, after suturing the wound, the barb segment 1 is completely buried in the skin, one or both ends of the smooth segment 2 are buried in the skin, and the rest is exposed outside the skin. That is, the length of a single barb segment 1 is shorter than the suture distance of a single needle. This reduces the limitation on the suture distance of a single needle, thus making it easier for the operator to use.

[0031] The third type, such as Figure 3 As shown, after suturing the wound, one or both ends of the barb segment 1 are exposed outside the skin, while the rest is buried inside the skin, and the smooth segment 2 is completely exposed outside the skin. That is, the length of a single barb segment 1 is longer than the suture distance of a single needle, allowing the barb segment 1 to be exposed. This also reduces the restriction on the suture distance of a single needle, thus making it easier for the operator to use.

[0032] Generally, if a high anchoring force of the barb segment 11 within the tissue is required, the third type of suture can be selected. If a high degree of minimal damage to the surface skin of the wound is required, the second type of suture can be selected. If both a high degree of anchoring force of the barb segment 11 within the tissue and a high degree of minimal damage to the surface skin of the wound are required, the first type of suture can be selected. The selection criteria are not limited to these and depend on the actual situation.

[0033] It is important to note that the multiple barbed segments 1 and multiple smooth segments 2, spaced out at intervals, refer to... barbed segment 1 - smooth segment 2 - barbed segment 1 - smooth segment 2..., and so on. Furthermore, Figure 1 , Figure 2 and Figure 3 In the diagram, solid lines represent areas exposed outside the skin, while dashed lines represent areas buried under the skin.

[0034] In this embodiment, each barb segment 1 has multiple barbs 11, and the barbs 11 can have various shapes, such as... Figure 1 The fishbone shape shown Figure 2 and Figure 3 The triangular shape shown is not the only variation. Other shapes not shown, such as spiky shapes, are also possible. When the barbs 11 are triangular, in a single barb segment 1: multiple barbs 11 can be spirally arranged along the extending direction of the barb segment 1, such as... Figure 2 As shown; multiple barbs 11 are also arranged on one side along the extension direction of barb segment 1, such as Figure 3 As shown.

[0035] In one embodiment, such as Figure 2 As shown, the middle part of the smooth segment 2 is the widened part 21.

[0036] This allows the wound to have a larger stress-bearing area, especially under high tension, avoiding skin injury caused by pressure from sutures after closure, and further facilitating rapid wound healing.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, an intermittent barbed suture assembly includes the intermittent barbed suture thread in any of the above embodiments.

[0038] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the intermittent barbed suture assembly also includes a suture needle 3 and an anti-detachment stop 4. The suture needle 3 is connected to the beginning of the intermittent barbed suture, and the anti-detachment stop 4 is connected to the end of the intermittent barbed suture. The anti-detachment stop 4 can be of various shapes, such as a circular piece, a triangular piece, a rectangular piece, or a cuboid shape.

[0039] Specifically, this type of spaced barbed suture assembly is suitable for unidirectional suturing.

[0040] In one embodiment, the spaced barbed suture assembly further includes two suture needles 3, one suture needle 3 connected to the beginning of the spaced barbed suture and the other suture needle 3 connected to the end of the spaced barbed suture.

[0041] Specifically, this type of spaced barbed suture assembly is suitable for bidirectional suturing.

[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
