Embodiment 1

[0020] Embodiment one: see figure 1 , a kind of reticular skin grafting punching mold of the present invention, its metal body 1 is flat plate shape, is provided with several evenly arranged elliptic through-holes 2 on this flat-shaped metal body 1, wherein two adjacent through-holes The long axis is vertical.

Embodiment 2

[0021] Embodiment two: see figure 2 , a kind of reticular skin grafting punching mold of the present invention, its metal body 1 is cylindrical shape, and the metal body 1 of this cylindrical shape is provided with several evenly arranged oval-shaped through-holes 2, wherein adjacent two through-holes The long axis of the hole is vertical; one end of the cylindrical metal body is a duckbill-shaped 3 blind ends.

Embodiment 3

[0022] Embodiment three: see image 3 , Figure 4 , a mesh skin grafting punching mold of the present invention, its metal body 1 is in the shape of a flat tube, and the metal body 1 in the shape of a flat tube is provided with several evenly arranged oval through holes 2, wherein two adjacent holes The long axis of the hole is vertical; one end of the metal body in the shape of a flat tube is a duckbill-shaped 3 blind ends.

[0023] When the present invention is used, the skin is spread on the metal body 1, and holes are punched on the skin corresponding to the through holes 2 on the metal body 1, and then skin grafting is carried out, and blood flows out from the holes, which not only ensures that the skin can be planted on the wound during the operation , and solved the problem of large wound and insufficient skin volume.

Abstract

The invention relates to a medical instrument, in particular to a mesh-shaped skin grafting punching die, comprising a metal body which is provided with a plurality of through holes which are uniformly arranged on the metal body; adjacent through holes are vertical to each other. The mesh-shaped skin grafting punching die solves the problem that the operation wound surface is large and the skin quantity is not enough and solves the flow guiding of accumulated blood and accumulated liquid under the grafted skin, thus ensuring the surviving problem of the grafted skin on the wound surface; furthermore, during the skin grafting operation, regular punching is carried out according to the uniformly arranged through holes so as to ensure that the skin grafting area to be regularly enlarged.

Description

technical field [0001] The invention relates to a medical device. Specifically relates to a mesh skin grafting punching mold. Background technique [0002] Congenital absence of a vagina is a common congenital malformation of the female reproductive system, with an incidence of 1:4000 to 1:10000 newborns. As far back as the time of Hippocrates, the absence of the vagina and its treatment have been documented. At present, there are many ways to reconstruct the vagina. Except for a very small number of people who unconsciously adopt the non-surgical method of simple pressure expansion, most of them use surgical methods to reconstruct the vagina, that is, through the mucous membrane of the depression behind the urethral opening, between the urethra and the rectum. A blind-end cave that is larger than the normal vagina is stripped out. After the cave is built, the four walls of the cave are covered with different tissues (skin, oral mucosa, amniotic membrane, allogeneic tissue...
