Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a bionic suture patch. Background Art
[0002] When people have small wounds on their skin, they often use Band-Aids to apply them to the affected area for treatment. If the wound is large, surgical sutures are often used for suture. Sutures are divided into absorbable and non-absorbable sutures. With the continuous improvement of medical standards, a suture patch has appeared on the market. The suture patch is applied on both sides of the wound, and the thread bundle is gently tightened to make the two sides of the suture patch close together to fit the wound surface. Compared with Band-Aids, this suture patch can adapt to larger wounds and has better breathability. However, compared with suture treatment with sutures, the suture patch can only close the skin surface and cannot close the deep part of the wound.
[0003] Existing suture patches, when applied on both sides of the affected area, can only close the wound on the surface of the affected skin, which is not conducive to the healing of the deep wound. The use effect of the suture patches is not good. This solution solves this technical problem. Utility Model Content

[0024] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.
[0025] See also Figure 1-Figure 5 A bionic suture patch includes a first patch 1 and a second patch 2, and also includes a plurality of occlusal structures 3 connected between the first patch 1 and the second patch 2. The bottom sides of the first patch 1 and the second patch 2 are both provided with a hydrogel patch 5 that adheres to the skin;
[0026] A support sleeve 11 is provided on the body 1, and a support sleeve 21 is provided on the body 2. The occlusal structure 3 includes a thorn needle 31 that slides through the support sleeve 11, a thorn needle 32 that slides through the support sleeve 21, and a locking assembly 4 connected between the thorn needle 31 and the thorn needle 32. One end of the thorn needle 31 and one end of the thorn needle 32 are respectively inserted into the skin from both sides of the wound, and the other end of the thorn needle 31 and the other end of the thorn needle 32 are connected through the locking assembly 4.
[0027] The locking assembly 4 includes a support bar 1 41 having one end connected to the other end of the puncture needle 1 31 , a support bar 2 42 having one end connected to the other end of the puncture needle 2 32 , and locking sleeves 43 respectively provided on the support bar 1 41 and the support bar 2 42 . The support bar 1 41 and the support bar 2 42 are locked to each other through the two locking sleeves 43 .
[0028] Ratchets 44 are provided on the sides of the support bar 1 41 and the support bar 2 42 , and ratchet pieces 431 are provided on the sides of the locking sleeve 43 . The support bar 1 41 and the support bar 2 42 are locked to each other through the cooperation of the ratchet teeth 44 and the ratchet pieces 431 .
[0029] One end of each of the puncture needle 1 31 and the puncture needle 2 32 is provided with a hook tooth 33 , and the puncture needle 1 31 and the puncture needle 2 32 pierce the skin through the hook tooth 33 . The puncture needle 1 31 and the puncture needle 2 32 are both made of absorbable material.
[0030] The support sleeve 1 11 and the support sleeve 2 21 are both arc-shaped. The curvature of the needle 1 31 and the support bar 1 41 is the same as that of the support sleeve 1 11 . The curvature of the needle 2 32 and the support bar 2 42 is the same as that of the support sleeve 2 21 .
[0031] The cross-sections of needle 1 31 and needle 2 32 are both circular, and connecting portions 34 are provided between needle 1 31 and support bar 1 41 as well as between needle 2 32 and support bar 2 42. The cross-sectional area of connecting portions 34 is smaller than the cross-sectional area of needle 1 31 and needle 2 32, which is more conducive to the separation of needle 1 31 and needle 2 32 from support bar 1 41 and support bar 2 42 after degradation.
[0032] The hook teeth 33 of the first needle 31 are detachably in contact with the bottom side of the first body 1 , and the hook teeth 33 of the second needle 32 are detachably in contact with the bottom side of the second body 2 .
[0033] The specific working process and principle of this utility model:
[0034] See also Figure 1 , the patch 1 and the patch 2 are respectively attached to the two sides of the wound through the hydrogel patch 5, see Figure 3 , gently press the body 1 and the body 2 through the support sleeve 11 and the support sleeve 21, so that the needle 1 31 and the needle 2 32 pierce the skin, see Figure 4The two locking sleeves 43 are held in the hands to move the support bar 1 41 and the support bar 2 42 away from each other. At this time, the ratchet teeth 44 of the support bar 2 42 slide in the locking sleeve 43 of the support bar 1 41, and the ratchet teeth 44 of the support bar 1 41 slide in the locking sleeve 43 of the support bar 2 42. The support bar 1 41 is guided by the support sleeve 11 to insert the thorn 1 31 deep into the skin. At the same time, the support bar 2 42 is guided by the support sleeve 21 to insert the thorn 2 32 deep into the skin. At this time, the thorn 1 31 and the thorn 2 32 are close together, and through the action of the hook teeth 33, the thorn 1 31 and the thorn 2 32 are close together, imitating the process of ant teeth biting. After the bite structures 3 are completed together on the skin of the wound, when the hands are released, the ratchet teeth 44 on the support bar 1 41 and the support bar 2 42 are locked by the spines 431, preventing the thorn 1 31 and the thorn 2 32 from falling out of the skin.
[0035] Since both needle 1 31 and needle 2 32 are made of absorbable material, which is the same as the absorbable suture needle in the prior art, they will not be described in detail here. After a specific period of healing, needle 1 31 and needle 2 32 are absorbed by the skin and are separated from support bar 1 41 and support bar 2 42 at the connecting portion 34, respectively. Finally, patch 1 1 and patch 2 2 are removed from the affected skin, completing the wound treatment.
[0036] By holding the two locking sleeves 43, the support bar 1 41 and the support bar 2 42 are moved away from each other. The support bars 1 41 and the support bar 2 42 are guided by the support sleeves 1 11 and the support sleeves 2 21, and the puncture needles 1 31 and 32 are inserted into the two sides of the wound. Under the action of the adhesion of the body sticker 1 1 and the body sticker 2 2 to the wound, the bite effect created by the puncture needles 1 31 and 32 together is inspired by the bite of ant teeth. The bionic structure closes the deep part of the wound, resulting in better healing effect of the deep wound.
[0037] By providing hook teeth 33 at the ends of the first needle 31 and the second needle 32, on the one hand, after the suture patch is applied to the wound, the first needle 31 and the second needle 32 can be easily penetrated into the skin by pressing the first support sleeve 11 and the second support sleeve 21. On the other hand, after penetrating deep into the skin, the hook teeth 33 can anchor the first needle 31 and the second needle 32, so that the suture patch is more firmly bonded to the skin and the wound healing effect is better.
[0038] The ratchet teeth 44 on the support bar 1 41 and the support bar 2 42 are locked with the ratchet piece 431 on the locking sleeve 43 to further fix the thorn needle 1 31 and the thorn needle 2 32 so that the thorn needle 1 31 and the thorn needle 2 32 are more firmly and reliably connected to the skin. The ratchet piece 431 is made of a flexible material. When installing the support bar 1 41 and the support bar 2 42, the ratchet piece 431 can be deformed to facilitate the smooth insertion of the support bar 1 41 and the support bar 2 42 into the locking sleeve 43.
[0039] The puncture needle 1 31 and the puncture needle 2 32 are made of absorbable material, and the cross-section of the connecting part 34 is small, so that the puncture needle 1 31 and the puncture needle 2 32 can be separated from the support bar 1 41 and the support bar 2 42 after degradation. The body sticker 1 1 and the body sticker 2 2 are made of breathable material, which has a better healing effect on the wound.
[0040] The technical features not described in the present invention can be realized by or by adopting the existing technology, and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
