Surgical methods for skin grafts?
1, Epidermis skin piece
Skin-only epidermis layer and a little dermal papilla layer are the thinnest skin graft. The advantage is especially easy to survive, and skin is not easy to leave scars. However, because the surface is very easy to shrink after the transplant, the color will become darker, in cosmetic surgery is not used, mainly to cover some infected wounds.
2, medium thick skin piece
Contains epidermis and part of dermis, Burn Cosmetic Skin Graft Instruments the color change that survives is lighter than epidermis skin piece, and the texture is soft, can tolerate certain friction. However, because of its darker color, it also restricts the application of facial cosmetic surgery. Because this kind of skin is rich in source, easy to cut and grow easily, Burn Cosmetic Skin Graft Instruments it is sometimes used in the shaping of limbs and trunk.
3. Full Thickness Skin film
This kind of skin is more commonly used in cosmetic plastic surgery, the advantage is that after survival and normal skin color close, there is a soft feeling, good elasticity, Burn Cosmetic Skin Graft Instruments can withstand friction and oppression, basic can maintain the original skin color. The disadvantage is that the skin area is restricted and the growth condition is higher.
4. Full thickness skin with vascular network
Skin transplant Instruments
Commonly used surgical equipment.
In the case of stable vital signs, skin grafts are used as early as possible in the hospital to remove the necrotic tissue from the wound. Deep ⅱ° wound can retain thin layer dermis deep tissue, Burn Cosmetic Skin Graft Instruments using cutting scab method, the wound need scalpel will cut the edge of the incision neat, convenient and free skin patch fine suture. Invasive radical hemostasis, Burn Cosmetic Skin Graft Instruments full rinse to be skin.
The choice of the skin donor area of the middle thickness fault is the back, the side chest, the abdomen, the anterolateral thigh, the medial thigh and the calf. The wound area of the 10%TBSA adopts the drum-type skin-picking machine combined with the roller to take the skin knife or the electric cutting machine to cut the thin medium thick skin. No matter what kind of skin-pickup device is applied, Burn Cosmetic Skin Graft Instruments the 10-3/epinephrine saline is injected into the donor area.
When the roller blade is taken, the skin graft device in the hospital should be fully taken by the donor and the assistant on the adult back can be cut to the width of the CM, the area of $number cm2 of the entire thin medium thick skin, drum-type pick-up machine using continuous skin technology can also be cut to the area of $number cm2 large Zhang Zhengho skin.
In the skin thinner parts of the body, such as lower abdomen, thigh inside, Burn Cosmetic Skin Graft Instruments found that the skin donor area of the wound has small particles of fat exposure, in the hospital skin transplant equipment should be another blade thick scalp covering the base. With multilayer Vaseline gauze covering the wound of the donor area, the thick cotton cushion is pressed and bandaged, $number D removes the outer dressing, preserves the inner layer Vaseline gauze, until the wound heals itself.
The long axis of skin graft in the hospital is perpendicular to the longitudinal axis of the area, the skin piece is stitched and fixed with the edge of the 3/0 silk thread blanket, and the continuous suture between the skin and the skin.
If the roller to pick the skin blade edge to form a small serrated shape, should be slightly trimmed to benefit the skin and the skin piece docking tightly neat, and strive to skin graft without exposing any wounds.
In the hospital skin transplant equipment should pay attention to special areas such as axillary, neck, buttocks, perineum should be packed with coarse silk thread fixed dressings, and then pressurized bandaging; The 1 WK was first replaced with a conventional plaster-supported brake. If the first change of the dressing is found to have a skin graft or a poor skin graft, should immediately replenish the skin graft.
Risk and prevention of surgical treatment of skin graft instruments
The possible complications of skin graft: partial deformity, deletion and dysfunction after resection of partial tumor.
Through the introduction of the above-mentioned skin transplant devices, I believe that we have a good understanding of the effect and side effects of skin grafts. Burn Cosmetic Skin Graft Instruments To avoid the complications of skin graft equipment, you must go to the normal hospital for treatment.
Aesthetics of skin graft instruments
Under hyperbaric oxygen, the oxygen partial pressure and the increase of oxygen storage in tissue can enhance the growth vigor of the tissue, promote the growth of granulation tissue, reduce the exudation and bacterial infection, make the wound fresh and clean, and create good condition for skin grafting.
The high partial pressure oxygen in the tissue before the transplanted skin or skin flap and the blood circulation in the skin area have not been established, which can reduce the persistent hypoxic state caused by the lack of blood supply in the transplanted skin graft.
The cell's Division and proliferation ability is closely related to the oxygen partial pressure in the tissue. When the oxygen partial pressure of the extracellular fluid is below 1.3kPa (10MMHG), the cells no longer divide and no longer synthesize collagen fibers. Under hyperbaric oxygen, Burn Cosmetic Skin Graft Instruments the oxygen partial pressure increases, the cell is active, produces the collagen and the newborn capillary, promotes the blood circulation establishment. The circulation of blood between the transplanted skin and the skin area provides sufficient blood and oxygen to the graft flap or flap, thus increasing the survival rate of the transplanted skin.
