Description
Technical field
The present invention relates to and a kind ofly cut crust machine for the electronic of deepⅱdegreeburn.
Background technology
At present, deepⅱdegreeburn is the Focal point and difficult point of burn surgery area research and treatment always.The application of dermabrasion art in deepⅱdegreeburnwound more and more comes into one's own.Dermabrasion, is equal to mill skin art in broad terms, refers to and utilizes apparatus to remove part skin histology by shearing force, form wound surface, mobilize edge of wound and substrate health tissues epithelization again, has reached wound healing or has improved the therapeutic purposes of skin appearance.Sense stricto dermabrasion refers to uses shaggy instrument, wound surface carries out grind, wipe, remove slough, with needle point sample hemorrhage or organize general red reach healthy layer for degree.The wound surface of degree of mixing wound surface and infection period, because crust is sliding, hard, current existing milling drum is less due to grinding machine head, and operate comparatively slow, grinding efficiency is low, is unsuitable for the Wound treatment of larger area.Sand paper dermabrasion can be infected with wound tissue because the glass dust on it departs from, and is difficult to cleaning.Various dermabrasion utensil has its limitation.For this reason, be badly in need of finding a kind of new technique improving crust excision to raise the efficiency, reduce wound tissue pollution, protection medical personnel personal safety.
Chinese patent 201220138558.2 reports a kind of electric shift burn dermabrasion device, it utilizes motor to drive dermabrasion cover to rotate the incrustation of removing the wounded's burn site, this patent is electric drive, the physical demands to clinicist can be alleviated, but this patent is not removed in time to the slough that grinding is removed, can produce and splash and remain, affect the judgement to Wound depth, in clinical practice, there is major defect:
Chinese patent 02256217.6 reports a kind of burn scald abrading machine for for medical use, it utilizes motor to drive coupled rotor to rotate to remove crust tissue, this patent sharpener does not have tool changing function, along with the carrying out of grinding, the grinding hole of tool surface will removed dead skin block, affect grinding function, and a kind of sharpener only corresponding a kind of cutter, be unfavorable for recycling.
Chinese patent 201020004302 reports a kind of burn wound dermabrasion machine, and it utilizes the dermabrasion head that dermabrasion cover is equipped with in manual operations to clear up wound surface.It utilizes the dermabrasion head that dermabrasion cover is equipped with in manual operations to clear up wound surface, this patent needs to carry out dermabrasion operation by hand, higher to the physical fitness requirement of clinicist, significantly operating time be can increase during process large-area burn wound, operating difficulty and anesthetic risks increased.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, providing a kind of and cutting crust machine for the electronic of deepⅱdegreeburn.
For achieving the above object, the present invention adopts following technical proposals:
A kind ofly cut crust machine for the electronic of deepⅱdegreeburn, comprise fuselage, fuselage latter half is the handle meeting human engineering, motor is provided with in fuselage, the main shaft of motor is connected with the first hollow power transmission shaft, and the first power transmission shaft is connected with second driving shaft, and second driving shaft enters in the sleeve be connected with front fuselage through front fuselage, second driving shaft front end is stretched out outside sleeve and is connected with alligator clamp shell type handle of a knife, and Cutting tool installation manner is on alligator clamp shell type handle of a knife.
