Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a skin sampler suitable for skin transplantation.
Background
Autologous skin grafting is a common method of treating skin defects caused by wounds, burns and other factors. Skin grafting includes free grafting of skin tissue alone and grafting of pedicle flaps or tubes of skin and subcutaneous tissue simultaneously. The viability of the transplanted skin depends primarily on whether the transplanted skin and the dermal tissue establish effective blood circulation. Factors influencing the survival of the transplanted skin sheet or skin flap comprise wound infection, skin sheet movement, pedicle torsion compression of a leather tube or skin flap, excessive fat of the leather tube and the like, and the hyperbaric oxygen treatment is beneficial to the success of skin transplantation.
Under high pressure oxygen, the oxygen partial pressure and oxygen storage capacity in the tissue are increased, so that the growth activity of the tissue in a skin receiving area can be enhanced, the growth of granulation tissue is promoted, the exudation and bacterial infection of the wound surface are reduced, the wound surface is fresh and clean, and good conditions are created for skin grafting.
Before the blood circulation of the transplanted skin or skin flap and the skin receiving area is not established, the high-partial-pressure oxygen in the tissue can relieve the continuous anaerobic state of the transplanted skin due to the lack of blood supply, and is favorable for the survival of the transplanted skin.
The cell 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 less than 1.3kPa (10mmHg), the cells are no longer dividing and collagen fibers are no longer synthesized. The oxygen partial pressure around the cells is increased under high pressure oxygen, the cells are activated, collagen and new capillaries are generated, and the establishment of blood circulation is promoted. The blood circulation established between the transplanted skin and the recipient area supplies sufficient blood and oxygen to the transplanted skin patch or flap, thereby increasing the survival rate of the transplanted skin.
A skin sampler commonly used in skin transplantation operation is a skin trephine, the depth of the skin trephine needs to be determined every time sampling, the sampling depth is not easy to control, and the sampling depth is not consistent.
