Description
Technical field
The present invention relates to a kind of cut crust machine for the electronic of deep-degreeburn.
Background technology
At present, deep-degreeburn is always burn surgery area research and the emphasis for the treatment of and difficult point.The application in deep-degreeburnwound of the dermabrasion art increasingly comes into one's own.Dermabrasion, is equal to grind skin art in broad terms, refers to that utilizing apparatus to pass through shearing force removes partial skin tissue, forms wound surface, mobilizes edge of wound and substrate health tissues epithelization again, reached wound healing or improved the therapeutic purposes of skin appearance.Sense stricto dermabrasion refers to use shaggy instrument, carries out grinding, wiping on wound surface, removes slough, hemorrhage with needle point sample or organize and general red reach healthy layer for degree.Degree of mixing wound surface and the wound surface of infection period, owing to crust is sliding, hard, current existing milling drum is less due to grinding machine head, and operation is relatively slow, and grinding efficiency is low, is unsuitable for the Wound treatment of larger area.Sand paper dermabrasion can depart from contamination wound tissue because of glass dust thereon, it is difficult to cleans.Various dermabrasion utensils have its limitation.To this end, be badly in need of finding a kind of new technique of crust excision that improves to improve efficiency, to reduce wound tissue pollution, protection medical personnel's personal safety.
Chinese patent 201220138558.2 reports a kind of electric shift burn dermabrasion device, it is to utilize motor to drive dermabrasion set to rotate the incrustation removing the wounded's burn site, this patent is electric drive, the physical demands to clinicist can be alleviated, but the slough that grinding is not removed by this patent is removed in time, splashing and residual, the impact judgement to Wound depth can be produced, have the severe disadvantage that in clinical practice
Chinese patent 02256217.6 reports a kind of burn scald abrading machine for for medical use, it is to utilize motor to drive coupled rotor to rotate to remove crust tissue, this patent sharpener does not has tool changing function, carrying out along with grinding, the grinding hole of tool surface will removed dead skin be blocked, affect grinding function, and the most corresponding a kind of cutter of a kind of sharpener, be unfavorable for recycling.
Chinese patent 201020004302 reports a kind of burn wound dermabrasion machine, and it is that wound surface is cleared up by the dermabrasion head utilizing manual operations to overlap equipped with dermabrasion.It is that wound surface is cleared up by the dermabrasion head utilizing manual operations to overlap equipped with dermabrasion, this patent needs to carry out dermabrasion operation by hand, higher to the physical fitness requirement of clinicist, operating time can be dramatically increased when processing large-area burn wound, increase operating difficulty and anesthetic risks.
Summary of the invention
It is an object of the invention to as overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of cut crust machine for the electronic of deep-degreeburn.
For achieving the above object, the present invention uses following technical proposals:
A kind of cut crust machine for the electronic of deep-degreeburn, including fuselage, fuselage latter half is the handle meeting human engineering, motor it 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 being connected with front fuselage through front fuselage, second driving shaft front end is stretched out and is connected with alligator clamp shell type handle of a knife outside sleeve, and Cutting tool installation manner is on alligator clamp shell type handle of a knife.
