Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a needle-free epidermal stapler and a finished product assembly. Background Art

[0002] The traditional needle-and-thread suturing method for skin wounds will inevitably cause new damage to the skin, suture allergies, and unsightly wound healing with a "centipede foot" appearance. Therefore, needle-free epidermal staplers are now commonly used to suture wounds. Their working principle is the same as sutures, but they do not damage the skin. Through physical action, the skin on both sides of the wound is pulled together and fixed to help the wound heal.

[0003] However, the needle-free epidermal stapler in the prior art still has the following shortcomings:

[0004] 1. It is easy to deform and cannot fully fit the wound and the skin surface on both sides, resulting in poor suturing effect;

[0005] 2. It is easy to fall off when tightening the suture, causing secondary damage to the wound;

[0006] 3. The tightness of the wound suture cannot be controlled, and the tightness of the skin cannot be adjusted during the wound healing process;

[0007] 4. Poor ventilation can easily lead to moisture accumulation at the wound, which is not conducive to wound healing;

[0008] 5. After suturing, the clothes are likely to stick to the sutures of the wound, which may easily cause the sutures of the wound to be torn or even the entire suture device to be separated from the body. Utility Model Content

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] See also Figures 1 to 2 According to an embodiment of the present invention, on the one hand, a needle-free epidermal stapler is provided, comprising a first fixing plate 1, a second fixing plate 2 and a contact plate 3. Specifically, the first fixing plate 1 is fixed to the skin surface on one side of the wound, and the second fixing plate 2 is fixed to the skin surface on the other side of the wound. The contact plate 3 is fixedly connected to the second fixing plate 2. The function of the contact plate 3 is to pull the second fixing plate 2 in a direction close to the first fixing plate 1 and connect it to the first fixing plate 1 in a detachable manner to suture the wound on the skin surface.

[0038] In particular, the first fixing plate 1, the second fixing plate 2 and the contact plate 3 are respectively embedded with a first supporting plate 4, a second supporting plate 5 and a third supporting plate 6. The first supporting plate 4, the second supporting plate 5 and the third supporting plate 6 are preferably made of hard medical polymer materials, such as medical polypropylene, polyethylene, etc., the purpose of which is to increase the rigid structural design of the first fixing plate 1, the second fixing plate 2 and the contact plate 3, and the beneficial effects brought about include at least the following three aspects: First, the first fixing plate 1, the second fixing plate 2 and the contact plate 3 will not be deformed, are easy to pull, and are conducive to the accuracy of the movement of the contact plate 3, so as to perfectly suture the wound; Second, the first fixing plate 1 and the second fixing plate 2 can fully fit the skin surface, especially for the tight closure of the skin along both sides of the wound and near the edge, which plays a vital shaping role and greatly reduces the possibility of irregular shapes such as high and low bending when the wound is closed; Third, it avoids the situation where clothing is easily adhered to the seams, causing the seams to be torn or even the entire suture device to be separated from the body.

[0039] The above-mentioned abutment piece 3 is fixedly connected to the second fixing piece 2 through the connecting support piece 7. The two ends of the connecting support piece 7 are fixedly connected to the second support piece 5 and the third support piece 6 respectively. When the wound is sutured, the connecting support piece 7 contacts the upper side of the wound and is preferably made of transparent material so that the suture condition of the wound can be observed through the connecting support piece 7.

[0040] The first fixing plate 1, the second fixing plate 2 and the engaging plate 3 all have a layered structure. Specifically,

[0041] The first fixing plate 1 includes a fleece-surface Velcro 102 and a first double-sided tape 101, which are respectively bonded to the upper and lower sides of the first supporting plate 4, wrapping the first supporting plate 4 in the middle position to finally form a whole, wherein the first double-sided tape 101 is bonded to the skin surface on one side of the wound to fix the first fixing plate 1.

[0042] The second fixing plate 2 includes a first single-sided tape 202 and a second double-sided tape 201. The first single-sided tape 202 and the second double-sided tape 201 are respectively bonded to the upper and lower sides of the second support plate 5, wrapping the second support plate 5 in the middle position to finally form a whole, wherein the second double-sided tape 201 is bonded to the skin surface on the other side of the wound to fix the second fixing plate 2.

[0043] The abutting piece 3 includes a second single-sided tape 302 and a hook-surface Velcro 301, which are respectively adhered to the upper and lower sides of the third supporting piece 6, wrapping the third supporting piece 6 in the middle position to finally form a whole.

[0044] The hook-side Velcro 301 is matched with the fleece-side Velcro 102 to realize the detachable connection between the abutting piece 3 and the first fixing piece 1 , which is more convenient and safer than traditional needle and thread sewing.

[0045] In particular, a scale line 9 is provided on the upper side of the fleece-surface Velcro 102 for observing the position of the engaging piece 3 relative to the first fixing piece 1, so as to accurately control the bonding area between the hook-surface Velcro 301 and the fleece-surface Velcro 102. The beneficial effect thereof is that it is convenient to control the tightness of the suture according to the different sizes of the wound in actual circumstances. In addition, during the wound healing process, the tightness of the skin can also be adjusted to maintain the comfort of the patient.

[0046] The first support sheet 4 includes a first edge support portion 401 and a first extension support portion 402, wherein the first edge support portion 401 is arranged at the edge of the first fixing sheet 1 close to the wound, and the first extension support portion 402 is fixedly connected to the first edge support portion 401 away from the wound. The second support sheet 5 includes a second edge support portion 501 and a second extension support portion 502, wherein the second edge support portion 501 is arranged at the edge of the second fixing sheet 2 close to the wound, and the second extension support portion 502 is fixedly connected to the second edge support portion 501 away from the wound. In particular, the first extension support portion 402 and the second extension support portion 502 are preferably configured in a strip shape, and their widths are narrower than the widths of the first fixing sheet 1 and the second fixing sheet 2, respectively. Therefore, the contact area between the first double-sided tape 101 and the fleece-surface Velcro 102, as well as the contact area between the second double-sided tape 201 and the first single-sided tape 202 is larger, and the bonding strength is also greater, so that the first supporting sheet 4 and the second supporting sheet 5 can be more firmly embedded in the first fixing sheet 1 and the second fixing sheet 2, respectively, to avoid falling off during tightening and suturing, causing secondary damage to the wound.

[0047] In addition, the above-mentioned first double-sided tape 101, second double-sided tape 201, first single-sided tape 202 and second single-sided tape 302 all use non-woven fabric as the base material, and the first support sheet 4, second support sheet 5 and connecting support sheet 7 are all provided with multiple through holes 8 for ventilation. The purpose is to maintain the comfort of the patient when wearing the anastomosis device, and to allow air to participate in the metabolism of wound cells on the wound and the skin surface on both sides, which is conducive to accelerating the healing of the wound.

[0048] See also Figure 2 According to another embodiment of the present invention, a finished assembly is provided, comprising a release film 10 comprising a plurality of fixedly connected sub-release films 1001. Each sub-release film 1001 has a needle-free epidermal stapler attached to its upper side, thereby protecting the bottom surface of the needle-free epidermal stapler prior to use. The finished assembly is also convenient for portability and handling when multiple needle-free epidermal staplers are required for patients with large wounds.

[0049] In particular, the connection between two adjacent sub-release films 1001 is further provided with an easy-tear line 11, and the number of the needle-free epidermal stapler used can be freely selected.

[0050] The steps of using the utility model are:

[0051] Step 1: Suture the wound subcutaneously;

[0052] Step 2: Clean the wound and the surrounding skin surface, ensuring that blood stains, disinfectants, etc. are wiped away and kept dry;

[0053] Step 3: Attach the first fixing sheet 1 with scale lines 9 on the surface to a position approximately 3-5 mm on one side of the wound, and then attach the second fixing sheet 2 to a position approximately 3-5 mm on the other side of the wound;

[0054] Step 4: Pull the front end of the fitting piece 3 toward the first fixing piece 1 to the ideal position, adhere the front end of the fitting piece 3 to the upper side of the first fixing piece 1 and gently press and smooth it so that the hook surface Velcro 301 fully contacts the fleece surface Velcro 102 to complete the wound fitting.

[0055] Step 5: If the wound is large, multiple needle-free epidermal staplers on the finished component can be removed one after another to suture the wound. The interval between two adjacent needle-free epidermal staplers is set to 8-10 mm.
