Description
Technical field
This utility model relates to technology technical field of medical instruments, specifically, is that a kind of novel partculate skin is fast
Speed skin apparatus processed.
Background technology
The wretched insufficiency that patients with major full-thickness burn is originated due to autologous skin, its wound repair always burn
One difficult problem of clinical economics.Owing to wound surface fails timely and effective closing and the severe systemic infection that causes and all
Many visceral complications, can jeopardize the life of patient at any time.This has been done substantial amounts of research by Chinese scholars, its
In, Chinese scholar the wear debris emission art invented is because of extension ratio big (maximum amplifiable 20 times), skin-grafting
Efficiency and survival rate are high and become one of main wound repair technology of patients with major full-thickness burn.
Wear debris emission art is made by skin apparatus processed and autologous skin is made smaller than the microgranule of 1 mm square,
It is uniformly coated on the carrier such as allograft skin or biological dressing, is then covered by the wound surface removing slough,
The final amplification relying on microparticle skin reaches the permanent closure of wound surface.
Additionally, in cytologic experiment, more conventional enzyme digestion cell culture technology needs system too
Standby microparticle skin.
The current mode making microparticle skin mainly has two kinds, and one is to utilize tissue shear to make by hand, another kind of
It is to make by electronic onal mechanism.The equal existing defects of both microparticle skin production methods and deficiency.
Utilizing tissue shear to make microparticle skin by hand, speed is slow, and efficiency is low, and operating time is long, operative doctor labor
Momentum is big.Any operation is all the two-hit to patient, and operating time is the longest, hits the biggest, wind of performing the operation
Danger is the biggest.Additionally, the microparticle skin size that this mode makes is uneven, impact skin-grafting effect.
The operation principle of electronic onal machine is that electro-motor drives many group cutter head high speed rotating repeatedly to cut to reach
Onal purpose.This Zhi Pi mode automatization degree is high, can save a large amount of human and material resources, microparticle skin
Size is uniform, but the blade of high speed rotating has stronger impact dissection to cell, and cell injury is relatively big,
Skin graft survival rate is the highest.Therefore, the method is rarely employed in clinic.
Therefore, need badly a kind of efficiently, easily operation, skin grain size is uniform, cell injury is little novel partculate skin
Quickly skin apparatus processed.And yet there are no report about this quick skin apparatus processed.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, it is provided that a kind of operation efficient, easy, skin
The grain novel partculate skin skin the most processed apparatus that size is uniform, cell injury is little.
