Description
Technical field
This utility model relates to a kind of adjustable electric negative pressure scab grinding machine.
Background technology
The process of burn wound is the Focal point and difficult point of burn surgery area research and treatment always.Organizing of burnt degree is divided into slough, parabiosis tissue and normal structure from shallow to deep.Slough has lost blood fortune, namely starts by bacteria attack in a few minutes, and after wound, 6 hours bacterial content are up to 10
6/ cm
3.Parabiosis tissue refers to that cell damage, inflammatory reaction are strong, the obvious Level of organization of edema, two kinds can be had to lapse to direction: if by the bacteria attack from slough, then there is wound sepsis, and secondary tissue is downright bad; If Wound treatment is proper, there is not deep tissue infection, then recover blood fortune, cytothesis gradually.Therefore as early as possible, accurately remove the slough of burn wound and don't damage parabiosis tissue and normal structure, thus a series of pathophysiological change alleviating, reduce or eliminate burn toxin and cause, be the key issue of successful treatment skin burn.
Mode mainly expectant treatment and the operative treatment of current process burn wound.First according to perusal, the degree of depth of assessment tissue of burn, be divided into I °, shallow II °, dark II ° and III ° of wound surface.Wherein, I ° adopts with shallow II ° of wound surface expectant treatment of changing dressings, and dark II ° of wound surface application dermatome cuts crust to skin corium, and III ° of wound surface then needs deep fascia to organize full-thickness excisional with shallow.Current Wound treatment mode has been applied for many years, but all kinds of corrupt practices creep in: each area skin thickness of (1) whole body is different, the depth of burn that the same source of causing injury is caused may be unbalanced, and naked eyes are very inaccurate to the assessment of depth of burn, can cause the error of Wound treatment way selection.(2) I ° is not carried out the thorough debridement of wound surface with shallow II ° wound surface, easily sacrifices parabiosis tissue because of wound surface secondary infection; And dark II ° and III ° is all directly cut crust or cut crust to specific level, then can cause the excessive excision to parabiosis tissue and normal structure, sacrifice the local function after wounds healing.So think at present, optimal Wound treatment mode is the degree of depth without the need to assessing burn wound in advance, application accurately, the mode of successively debridement, from the superficial to the deep remove wound surface slough.This burn wound of debridement mode to each degree of depth has universality, decreases the destruction to parabiosis tissue and normal structure and waste while thoroughly removing slough.
According to clinical experience and Design Theory, adopt the mode of grinding can realize above-mentioned imagination to the accurate debridement of slough.Chinese patent " patent 201020004302 " discloses a kind of burn wound dermabrasion machine, it utilizes the dermabrasion head that dermabrasion cover is housed 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; Chinese patent " patent 201010002616.4 " discloses a kind of scab grinding machine, it utilizes driven by motor rotor to clear up wound surface, this patent is electric drive, the physical demands to clinicist can be alleviated, the height of scalable grinding cutter head is to control the degree of depth of grinding, by blowdown attractor, the slough that grinding is removed is removed in time, prevent from splashing and the residual impact on the judgement of Wound depth; But this patent has many defects in clinical practice: the grinding of (1) high speed rotating can cause the temperature of tissue surface obviously to raise, the blood coagulation of wound surface blood capillary can be there is, poor arterial inflow increases the weight of, cause secondary hot injury and wound surface deepening; (2) sharpener does not have auxiliary moving device, the long period can carry out grinding at place's wound surface, cause grinding excessively dark.For avoiding this problem, clinicist need lift sharpener repeatedly, and observe Wound depth after grinding and manual mobile sharpener position, clinical practice is very inconvenient.(3) sharpener does not have tool changing function, and along with the carrying out of grinding, the grinding hole of tool surface will removed dead skin block, and affects grinding function, and a kind of sharpener only corresponding a kind of cutter, be unfavorable for recycling.
