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 embodiment of the present invention is prepared by the following method:

[0011] First, design an incision along the edge of the scar. After local anesthesia, remove all scars with a depth of about 1-2mm; determine the amount of filling needed according to the size of the scar, and then determine the range of skin tissue cells to be extracted. Use a steel gear grinding machine to apply the above-mentioned wound. The normal skin within the range of 1-5cm around the formation of the surface layer of the wound; then use a multi-blade knife to cut the wound horizontally and horizontally to a depth of 0.5mm, while cutting, while collecting the skin tissue fragments on the knife, the collected skin The tissue fragments are immersed in heparin-containing saline to wash away blood clots; then all the above-menti...

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 present invention relates to a preparation method of living skin tissue cell polymer and its use in scar repair technology. technical background [0002] The reason for scar formation is that the defects of normal skin tissue cannot be completely healed, and the fibrous tissue replaces the wound to form a scar. The conventional method of treating scars, such as the incision method, is to draw and sew the wound edges on both sides after the scar is removed. Because the amount of skin is not enough, the two sides will become tighter after being pulled together. It is called high tension in medicine. The incision line is easy to split and proliferate, which can not achieve the purpose of removing scars. Another method to treat scars is skin grafting. One of the disadvantages of this method is that the color of the grafted skin is very different from the surrounding skin, and suture needles are left on all sides. Scars, and will leave larger scars on the s...
