Description
Technical field
The present invention relates to technology technical field of medical instruments, specifically, be a kind of novel partculate skin quickly skin apparatus processed.
Background technology
The wretched insufficiency that patients with major full-thickness burn is originated due to autologous skin, its wound repair is always up a difficult problem of Burns treatment.Owing to wound surface fails timely and effective closing and the severe systemic infection that causes and many visceral complications, the life of patient can be jeopardized at any time.This has been done substantial amounts of research by Chinese scholars, wherein, the wear debris emission art invented by Chinese scholar becomes one of main wound repair technology of patients with major full-thickness burn because extension ratio big (maximum amplifiable 20 times), skin-grafting efficiency and survival rate are high.
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, being 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, comparatively conventional enzyme digestion cell culture technology needs to prepare microparticle skin too.
The current mode making microparticle skin mainly has two kinds, and one is to utilize tissue shear to make by hand, and another kind 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, and the operative doctor amount of labour is big.Any operation is all the two-hit to patient, and operating time is more long, hits more big, and operation risk is also more big.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, it is possible to saving a large amount of human and material resources, microparticle skin size is uniform, but cell is had stronger impact dissection by the blade of high speed rotating, and cell injury is relatively big, and skin graft survival rate is not high.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
It is an object of the invention to for deficiency of the prior art, it is provided that a kind of operation efficient, easy, the novel partculate skin quickly skin apparatus processed that skin grain size is uniform, cell injury is little.
For achieving the above object, the present invention adopts the technical scheme that:
A kind of novel partculate skin quickly skin apparatus processed, described skin apparatus processed includes the first finger ring, the first straight-arm, the first linking arm, the first shears, rotating shaft, the second finger ring, the second straight-arm, the second linking arm, the second shears；Described first linking arm is connected with the second linking arm by rotating shaft；The first described linking arm and the second linking arm are copline or non-co-planar；The first described shears and the second shears are copline or non-co-planar；The first described shears is provided with son tiltedly blade or dentation sword；The second described shears is provided with female tiltedly blade or dentation sword.
Described the first finger ring, the first straight-arm, the first linking arm, the first shears are Integratively formed.
Described the second finger ring, the second straight-arm, the second linking arm, the second shears are Integratively formed.
The first described finger ring and the second finger ring are shaped as ellipse.
The first described shears is provided with four oblique blades of son, and has gap between adjacent two oblique blades of son；The second described shears is provided with four oblique blades of mother, and has gap between four oblique blades of mother；Oblique blade engages each other the oblique blade of described son with the mother of correspondence position.
The quantity of described first shears and the second shears is at least one.
The described distance between dentation sword is less than 1mm.
The invention has the advantages that:
1, a kind of novel partculate skin of the present invention quickly skin apparatus processed, efficiently, easily operates, and skin grain size is uniform, and cell injury is little；
2, being provided with son tiltedly blade and the oblique blade of mother, by the engagement between the oblique blade of son and the oblique blade of mother, it is achieved the shearing of microparticle skin, and the shear direction of microparticle skin is vertical direction, simple to operate；
3, it is provided with gap between adjacent son tiltedly blade or female oblique blade so that the microparticle skin completing to shear is discharged from gap, it is to avoid microparticle skin is detained, thus improving skin efficiency processed, reduces cell injury；
4, the quantitative design of son tiltedly blade and the oblique blade of mother is multiple, and arranges from transverse direction and genesis analysis, and microparticle skin make efficiency is high, shortens operating time, alleviates operation and hits, reduces operation risk；
5, being provided with the dentation sword being smaller than 1mm, through the microparticle skin that skin apparatus processed is sheared, its area is respectively less than 1 square millimeter, so makes the microparticle skin size made uniform.
