CONCRETE EMBODIMENT
[0029] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0030] Embodiment one:
[0031] A buckle device for a skin anastomat, like Figures 1 to 4As shown, including zipper rack 1 and elastic fastener 2, elastic fastener 2 elastic loose or close to the zipper rack 1 before and after the lengthening or shortening, elastic fastener 2 on the zipper rack 1 buckle can fix the distance of the zipper rack 1, thereby controlling the distance between the fixed block 3 and the elastic fastener 2, that is, controlling the distance between the wounds, and the elastic fastener 2 is in close contact with the skin, the lower end of the elastic fastener 2 is in close contact with the skin, such as adhesive contact, while the elastic fastener 2 is loose or closed only in the vertical direction to mobilize and will not affect the transverse wound closure distance.
[0032] Also includes a fixed block 3 connected to one end of the zipper rack 1, the fixed block 3 is in close contact with the skin, the fixed block 3 controls the length of the zipper rack 1 with the elastic fastener 2 to provide a closing force to the wound, the zipper rack 1 includes inner teeth 4 and outer teeth 5, the tip of the inner teeth 4 is flat, the top of the elastic fastener 2 is provided with a buckle tooth 6 engaged with or released from the zipper rack 1, the tip of the buckle tooth 6 is flat, effectively enhancing the tooth strength of the inner teeth 4 and the buckle tooth 6, the sharp corners are easy to wear, on the one hand, reducing the tooth strength, on the other hand, causing debris to fall into the wound, leading to infection, reducing the cure rate, increasing the tooth strength of the inner teeth 4 and the buckle tooth 6, reducing the wound pollution, and improving the service life of the product.
[0033] It is worth mentioning that the flat end of the buckle tooth 6 and the inner teeth 4 not only refers to the vertical surface perpendicular to the axis of the zipper rack 1, but also forms a complete inclined surface when they are in contact with each other, which also falls within the scope of the present utility model.
[0034] The top of the zipper rack 1 is usually a sharp corner, which is easy to break during production demolding, increasing production cost and greatly reducing the yield, which will increase the production burden of the manufacturer and shorten the service life of the product. At the same time, in order to cooperate with the zipper rack 1, the top of the elastic fastener 2 used for engagement is usually also a sharp corner. When adjusting the tightness of the skin surface stapler, the elastic fastener 2 is easy to cause the sharp corner to break when sliding on the inner teeth 4 of the zipper rack 1.
