Problems solved by technology

Conventional methods of treating scars, such as the incision method, are to draw and suture the two sides of the wound after the scar is removed. Because the amount of skin is not enough, the two sides will be tighter after being drawn together, which is called high tension in medicine. After the stitches are removed, The incision line is easy to crack and proliferate, so that the purpose of scar removal cannot be achieved; another method for treating scars is skin grafting. One of the disadvantages of this method is that the color of the grafted skin is quite different from that of the surrounding skin, and suture needles are left on the four sides scar, and it will leave a bigger scar at the skin removal site

Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with specific embodiments.

[0010] The living skin cell tissue cell polymer described in the embodiments of the present invention is prepared by the following method:

[0011] First design an incision along the edge of the scar, and after local anesthesia, remove all the scar with a depth of about 1-2mm; determine the amount of filling required according to the size of the scar, and then determine the range of skin tissue cells to be extracted, and use a steel gear grinding head grinder on the above wound surface The superficial wound is formed on the normal skin within the range of 1-5cm around; then the wound is cut vertically and horizontally with a multi-edged knife to a depth of 0.5mm, and the skin tissue fragments on the knife are collected while cutting, and the collected skin The tissue granules are soaked in heparin-containing saline to wash away the blood clot; then all the above g...

Abstract

The present invention relates to one kind of in vivo skin tissue cell polymer, which is prepared through the following steps: forming wound surface on health skin, criss-cross scratching the wound surface in the depth of 0.3-0.5 mm, collecting skin tissue segment from the cutter, setting the collected skin tissue segment in salt water containing heparin to wash out blood clot, shearing the segment repeatedly with eye scissors, rinsing to eliminate fat granules, and collecting the granules containing skin tissue cells to obtain skin tissue cell polymer. The skin tissue cell polymer is applied in scar repairing.

Description

technical field [0001] The invention relates to a preparation method of living skin tissue cell polymer and its application in scar repair technology. technical background [0002] The reason for the formation of scars is that the defects of normal skin tissue cannot be completely healed, and the fibrous tissue replaces and repairs the wound surface to form scars. Conventional methods of treating scars, such as the incision method, are to draw and suture the two sides of the wound after the scar is removed. Because the amount of skin is not enough, the two sides will be tighter after being drawn together, which is called high tension in medicine. After the stitches are removed, The incision line is easy to crack and proliferate, so that the purpose of scar removal cannot be achieved; another method for treating scars is skin grafting. One of the disadvantages of this method is that the color of the grafted skin is quite different from that of the surrounding skin, and suture...
