In order to make the illustration clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

[0035] Example 1

[0036] like Figures 1 to 4 As shown, the puncture-free epidermal incision suture device of this embodiment 1 includes a skin dressing 10, a wire hanging bracket 20 and a suture 30, wherein the wire hanging brackets 20 are placed side by side and spaced apart on the skin dressing 10, and the center distance between adjacent wire hanging brackets 20 is maintained at 8-12 mm. Preferably, the center distance between adjacent wire hanging brackets 20 is 10 mm, and there are multiple wire hanging brackets 20.

[0037] Specifically, the skin dressing 10 includes a first plate and a second plate, the first plate and the second plate are arranged in parallel, and a plurality of wire hanging brackets 20 are respectively arranged on the first plate and the second plate, and the wire hanging brackets 20 on the first plate are staggered and arranged with the wire hanging brackets 20 on the second plate to form a staggered arrangement structure in opposite directions, and the sutures 30 are arranged to be inserted into the wire hanging brackets 20 in sequence, and the sutures 30 are arranged in a Z shape on the skin dressing 10.

[0038] At this time, the wire hanging bracket 20 includes a bell mouth 21, a tongue 22 and a notch 23. The bell mouth 21 is arranged on the wire hanging bracket 20, so that the suture 30 can be inserted into the wire hanging bracket 20. The tongue 22 is located at the bottom of the bell mouth 21, so that the suture 30 can be clamped. In addition, the notch 23 is located opposite to the bell mouth 21. For places subjected to relatively large tension, the suture 30 can be wrapped around the circle 31 to improve the reliability of the suture 30 being inserted into the tongue 22.

[0039] Furthermore, skin dressing 10 comprises a flexible non-swellable material.

[0040] The epidermal incision suture device for puncturing the skin of the first embodiment is used as follows: Figure 3 As shown, the skin dressing 10 is applied to both sides of the skin incision 40, and the hanging wire brackets 20 on the two skin dressings 10 are arranged crosswise, and the incision 40 is closed by tightening the suture 30, as shown in FIG. Figure 4 As shown; after tightening the suture 30, a section of excess suture will grow out of the suture, which can be looped 31 on the end hanging bracket 20, or the excess suture can be cut off. The suture 30 presents a Z-shaped direction on the skin dressing 10, similar to the traditional Z-shaped suture method, which can not only withstand the incision tension in the Y-axis direction, but also withstand the tension in the X-axis direction, and can eliminate the tension stress on the incision caused by daily human activities as much as possible.

[0041] Example 2

[0042] like Figures 5 to 7 As shown, the difference between the present embodiment 2 and the embodiment 1 is that the wire hanging bracket 20 includes a wire holding film 25, an inclined groove 26 and a holding groove 27. The wire holding film 25 is embedded in the center of the wire hanging bracket 20, and the inclined groove 26 is connected to the holding groove 27. The wire holding film 25 can be made of a material such as silica gel that is easy to puncture and has good resilience and can hold the wire.

[0043] When the puncture-free epidermal incision suture device of the present embodiment 2 is used, it is similar to puncturing skin tissue. A suture needle is used to puncture the thread-holding film 25, and the suture 30 is passed through the thread-holding film 25. The oblique groove 26 and the holding groove 27 are located on the thread hanging bracket 20. The suture 30 enters the holding groove 27 through the oblique groove 26, so that the suture 30 can be clamped.

[0044] Example 3

[0045] The method for suturing epidermal incisions of the puncture-free skin of the third embodiment uses the puncture-free epidermal incision suturing device, and comprises the following steps:

[0046] Step S1, applying the first plate and the second plate of the skin dressing 10 to the two sides of the skin incision 40 respectively, and the first plate and the second plate are arranged relatively parallel, and the wire hanging bracket 20 on the first plate and the wire hanging bracket 20 on the second plate are arranged in a staggered manner to form a staggered arrangement structure in opposite directions;

[0047] Step S2, inserting the suture 30 into the thread hanging bracket 20 in sequence, so that the suture 30 forms a Z shape on the skin dressing 10;

[0048] Step S3, tighten the suture 30 to close the incision, and loop the excess end of the suture 30 around the hanging wire bracket 20 at the end 31.

[0049] Preferably, in step S1, the wire hanging bracket 20 includes a bell mouth 21, a tongue 22 and a notch 23, the tongue 22 is located at the bottom of the bell mouth 21, and the bell mouth 21 and the notch 23 are arranged opposite to each other; or, in step S1, the wire hanging bracket 20 includes a wire holding film 25, an oblique groove 26 and a slot 27, the wire holding film 25 is embedded in the center of the wire hanging bracket 20, and the oblique groove 26 is connected to the slot 27.

[0050] The epidermal incision suture device and suture method for puncture-free skin of the present invention selects softer materials that are more close to the skin as skin dressings, thereby causing no puncture damage to the skin around the incision. In addition, an external structure is used to hold the wire, thereby bearing the tension of the sutured wound, avoiding damage to the skin tissue, eliminating stress concentration, and avoiding the formation of scars during the healing process.

[0051] The suturing method of the present invention uses sutures to sew outside the tissue, and the closing effect on the wound is equivalent to that of the traditional method. The doctor is more skilled in this method. In addition, by adopting a similar traditional Z-shaped suturing method, it can not only withstand the incision tension in the Y-axis direction, but also withstand the pulling force in the X-axis direction, and can minimize the tension stress on the incision caused by daily human activities. The production cost is low, and the closing effect is closer to that of traditional suturing.

[0052] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
