Technical effects

Compared with the prior art, the material which is soft and more attached to the skin is selected to be used as the skin dressing, so that the skin around the incision is not punctured and damaged;

the external structure is adopted to clamp the thread, so that the tension of the wound to be sutured is borne, the damage to skin tissues is avoided, the stress concentration is eliminated, and scars are prevented from being generated in the healing process;

the method adopts suture to suture outside the tissue, the closing effect on the wound is equal to the traditional method, and doctors are more skilled;

compared with CN104825200A, the method adopts a similar traditional Z-shaped sewing mode, can bear incision tension in the Y-axis direction and tensile force in the X-axis direction, and can eliminate tension stress on the incision caused by daily activities of a human body as much as possible.

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Detailed Description

The technical contents of the preferred embodiments of the present invention will be more clearly understood and appreciated by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.

In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the present invention is not limited to the size and thickness of each component. The thickness of the components may be exaggerated where appropriate in the figures to improve clarity.

As shown in figures 1 and 2, the skin-puncture-free epidermal incision stitching instrument comprises a skin dressing 10, a thread hanging bracket 20, a bellmouth 21, a clamping tongue 22, a notch 23 and a suture 30. The skin dressing 10 is provided with a plurality of hanging wire brackets 20 which are arranged side by side at intervals, the central distance between the adjacent hanging wire brackets 20 is kept to be 10mm, and the hanging wire brackets 20 are arranged in a plurality. The bell mouth 21 is arranged on the thread hanging bracket 20, so that the thread 30 can be clamped on the thread hanging bracket 20 conveniently. The latch 22 is located at the bottom of the flare 21 to facilitate gripping the suture 30.
