Summary of the invention
The improvement project that the purpose of this invention is to provide a kind of suction nozzle of epidermis separator is more prone to, fast the bigger epidermis of separating area.
The object of the present invention is achieved like this: this suction nozzle is design in pairs, each to suction nozzle by cloudy piece and sun piece each one piece of compositions (being named of cloudy piece and sun piece just in order to narrate convenience, in fact a pair of suction nozzle can be named any one piece and be positive piece, and another piece then is cloudy piece).Suction nozzle can adopt anyly has the material of certain degree of hardness to make, as organic glass, glass, plastics, metal, these materials do not have ill effect to human body, are difficult for causing allergic reaction, adopt material transparent then can see through the variation that suction nozzle is observed skin at any time, use more convenient.The profile of the moon piece and sun piece of suction nozzle of partnering and big or small identical.Each free several wall of each piece suction nozzle surround a ducted body, this ducted body communicates with the external world by concave part 2, communicate with the vacuum suction pipe of epidermis separator by negative pressure channel 5, negative pressure channel communicates with each segment space in the concave part by the branch 12 of negative pressure channel.The inside of ducted body can be divided into two parts from top to bottom, and top is heating part 1, and the bottom is a concave part 2, and ducted body also can only be made up of part of concave part.The heating part is positioned at the top of concave part, and electro-heat equipment 4 and attemperating unit 6 can be installed, and the heating part communicates with concave part, and the heat that electro-heat equipment produces can be delivered to the skin that needs to inhale bleb smoothly, and can regulate and control the quantity of heat production of electro-heat equipment by attemperating unit.A mediastinum 3 can be set in the heating portion, be used for fixing electro-heat equipment, attemperating unit and negative pressure channel.The power circuit of electro-heat equipment and attemperating unit and negative pressure channel can be drawn from the top of suction nozzle or near the side at top, draw the passage at position and inlay sealing ring, to avoid circulation of air.Can adopt any energy bridging mode between heating part and the concave part, as screw thread, screw and binding agent, these bridging modes can make the slit between heating part and the concave part not have circulation of air when inhaling bleb, are convenient to the dismounting maintenance again.Lack the heating part, the suction nozzle of fluted portion only, the top of concave part is a complete top, and the top is connected with all around wall, constitutes a ducted body, and negative pressure channel enters the top from the side, is branched off into each following recess again.The collar extension of negative pressure channel can connect a pipe, as stainless steel tube, plastic tube, so that be connected with the vacuum suction pipe.Concave part is positioned at the bottom of suction nozzle, be used for contact need below the concave part and inhale the skin of bleb, one of the edge of this face becomes a complete ring-type (hereinafter referred to as ring-shaped edge 9) on every side, cyclic edge is positioned on the same plane, the other parts of groove can not exceed this plane downwards, to guarantee that following edge can be identical closely with skin, essentially no air admission when vacuum suction can form negative pressure.It is identical with size that ring-shaped edge below cloudy piece and the sun piece groove surrounds regional shape.Look up suction nozzle below, forms by recess 7 and protuberance 8 two parts in the concave part.The part that forms lacuna that caves inward is called recess, and the lacuna that recess forms can be Any shape, as cylindrical, prismatic or other is irregularly shaped, the degree of depth can be 2mm～50mm, be the best with 10～20mm generally, width is 1mm～50mm, is the best with 5mm～15mm.Each recess all communicates with negative pressure channel by the branch of negative pressure channel, further communicates with the vacuum suction pipe.Protuberance is for constituting the wall of recess, and recess is comparatively outstanding relatively, is that in the groove some surround the zone every the ring-shaped edge below, the groove and are slit into a plurality of recesses by a plurality of convex portions of certain distance apart.One piece of suction nozzle can have one to hundreds of even more recess and protuberance, and recess and protuberance are alternately.In the zone that ring-shaped edge surrounded below cloudy piece and the sun piece, the protuberance and the recess of cloudy piece and sun piece are complementary, and just at the identical position of relative position, wherein one piece is the position of protuberance, and another piece then is recess.Two pieces of suction nozzles that partner, at the identical position of relative position, the cross-sectional geometry of one piece recess in a pair of suction nozzle and the protuberance of another piece is similar figures, can be by circle, triangle, tetragon, polygon, other is irregularly shaped and the constituting of multiple shape, the area of recess cross section can be slightly larger than or equal the area of correspondence position protuberance cross section, and some can not be attracted the generation vesicle with the skin of avoiding need inhaling bleb.Because the edge of vitiligo skin lesion is often irregular, the suction nozzle of Zhi Zuoing in most of the cases all can not match with the skin lesion shape in advance, therefore, the present invention has designed some stoppers 10, suction nozzle according to circumstances can use also can not use stopper, any one cross-sectional area in these stoppers is less than or equal to the cross-sectional area of a recess, highly equal concave depth, one or more stoppers are combined side by side can just fill a part of inhaling first recess or a recess, but all recesses of this suction nozzle of complete filling that will combine for all stoppers that one piece of suction nozzle is made.The following making of stopper is by the blind pipe 11 of shallow diagonal to the deep, the blind pipe angle of inclination can be 10 °～70 °, with 30 °～45 ° be good, blind pipe collar extension and volume inside size to be inserting tweezers tip degree of being, so that insert in the groove corkage downwards with tweezers.Stopper can adopt any material of certain degree of hardness to make, and as glass, lucite, plastics, rubber, metal, timber, these materials are nontoxic to human body, are difficult for causing allergic reaction, be made into stopper after, when inhaling bleb, do not have obvious distortion.Before inhaling bleb, shape according to patient's vitiligo white macula district, select area below a pair of groove to be a bit larger tham the suction nozzle of white macula area, stopper with some is filled that part of recess that may attract normal skin, it is identical substantially to make suction nozzle can inhale the shape and the white macula district shape of part of bleb, a pair of suction nozzle is used for inhaling bleb white macula district (being subjected to the dermatotome), use the same method again make a pair of be subjected to the dermatotome to inhale the identical suction nozzle of suction nozzle of bleb, be used in skin donor site suction bleb.If on skin, inhale bleb with cloudy piece suction nozzle earlier, the pairing position of recess will produce vesicle, the pairing position of protuberance does not then have vesicle and occurs, be placed on the cloudy piece position of just having placed with positive piece then, positive piece recess is then corresponding to the pairing position of cloudy piece protuberance, attract the back to produce vesicle, positive piece protuberance has just in time attracted to form the position of vesicle corresponding to cloudy piece recess, makes the position that produces vesicle avoid continuing by vacuum suction.If earlier piece inhale bleb, and then inhale bleb in a sun piece position of just having placed with cloudy piece with sun, also can obtain same effect, the use of cloudy piece and positive piece is in no particular order.Earlier with one piece in cloudy piece and the sun piece after carrying out negative pressure suction bleb on the skin, another piece of reuse continues to attract in the position that had just attracted (if vesicle hinders the placement of suction nozzle, can under the sterile working, it be punctured, discharge bleb liquid), then will form a vesicle that is slightly smaller than area below the suction nozzle, cut the epidermis of vesicle, promptly disposablely obtained an epidermis that area is bigger.Suction nozzle is made into different specifications, select for use area below the suction nozzle to be a bit larger tham the suction nozzle of vitiligo white macula district area during use, (also can not use stopper fill to adjust inhale the shape at position of bleb with stopper after, directly select for use the specification size to be suitable for the suction nozzle of white macula size), respectively at skin donor site and be subjected to the dermatotome to inhale bleb simultaneously, removal is subjected to the epidermis of dermatotome vesicle bleb wall, take off the skin donor site epidermic grafting to being subjected to dermatotome (white macula district), the aseptic dressing wrapping, through after a while, can make the recovery pigment of white macula district uniformity.
Advantage of the present invention be can be disposable from being subjected to the dermatotome to remove large-area epidermis, can disposablely obtain large surface of skin simultaneously from skin donor site, simple to operate, with the skin donor site epidermic grafting to being subjected to the dermatotome only to need a few minutes to finish.Shortcoming is to be to adopt common suction nozzle to inhale the twice of bleb the suction time that bleb spent.Yet, considering the fritter epidermis is transplanted to one by one is subjected to the dermatotome need spend the time of dozens of minutes even several hrs, though use suction nozzle of the present invention to increase the suction bleb time, but obviously reduced the skin donor site epidermic grafting to being subjected to the required time of dermatotome, thereby reduced the total spended time of the whole process of epidermic grafting, reduced the workload of operator.Owing to be the monoblock epidermis to be covered be subjected to the dermatotome, make the recovery uniformity of operation back pigment, therapeutic effect is significantly improved.Therefore, the present invention possesses the value of promoting the use of.
