The specific embodiment
As shown in Figure 1, roller micropin instrument of the present utility model comprises: roller 1, its excircle are provided with a plurality of draw-in grooves 11, and the center, two sides is provided with installing hole 13; Embed the substrate microneedle configuration 2 in each draw-in groove 11, its a plurality of micropins 21 tops protrude in the excircle of roller 1; The handle portion 3 that is rotationally connected with roller 1.
Concrete, roller microneedle devices of the present utility model comprises roller, a plurality of substrate microneedle configuration and handle portion.Wherein, as shown in Figure 2, the excircle of roller is provided with a plurality of draw-in grooves 11, a plurality of substrate microneedle configuration embed respectively in each draw-in groove and with its formation one, the installing hole 13 at handle portion and roller center forms and is rotationally connected.When treating when operation, hold handle portion it is moved forwards or backwards, then roller drives the substrate microneedle configuration that is embedded in its excircle and rolls at skin surface along with the motion of handle portion, thereby reaches the purpose of treatment.
As shown in Figure 3, substrate microneedle configuration 2 of the present utility model comprises substrate 22 that is strip and a plurality of micropins 21 that in a row are fixed thereon.Wherein, the upper surface of substrate is plane or arc surface, in the draw-in groove 11 of its dismountable embedding roller, and a plurality of micropins that substrate is provided with are one-body molded with it, and the top of micropin protrudes in the excircle of roller, thereby can utilize the small syringe needle chafe of micropin, make active component effectively infiltrate skin, simultaneously micropin stimulates skin corium, and percutaneous self-healing ability is effectively desalinated small rut on the skin and the cicatrix on the skin.
For the substrate microneedle configuration that prevents to embed in the roller draw-in groove comes off, draw-in groove adopts the wedge-shaped slot of upper opening size less than the lower openings size, thereby the substrate microneedle configuration can be stuck in the wedge-shaped slot.Further, slide vertically in draw-in groove in order to prevent the substrate microneedle configuration, be provided with anti-skid structure in substrate microneedle configuration 2 and 1 on roller, this anti-skid structure comprises the lobe 23 of being located at substrate microneedle configuration 2 one sides and the groove 12 of being located at draw-in groove 11 1 sides and mating with lobe 23.
In the substrate microneedle configuration 2 employing polymeric materials of the present utility model one or more are mixed and made into, as making by the PMMA material, needle body of micropin 21 is circular cone structure or frustum of a pyramid structure on it, and row's number of the micropin on each substrate microneedle configuration is 1-4 row.When adopting frustum of a cone micropin, its vertical diameter is 0.02mm-0.2mm, and the bottom diameter is 0.04mm-1mm, highly is 0.2mm-3mm; When adopting frustum of a pyramid micropin, its vertical minimum length is 0.02mm-0.2mm, and the bottom minimum length is 0.04mm-1mm, highly is 0.2mm-3mm.Adopt tiny micropin to fill the object of arbitrary dimension, therapeutic effect is good.
As shown in Figure 4, handle portion 3 of the present utility model comprises that an end has the handle 31 of U type support 32 and is arranged at a pair of back shaft 33 of U type support 32 opening inboards in opposite directions.Back shaft 33 inserts in the installing hole 13 of roller, form with roller to be rotationally connected, thereby when handle portion was moved, drive roller and the substrate microneedle configuration that is embedded on the roller is rolled on skin.In actual use, handle portion 3 can be used always, when the micropin in certain the substrate microneedle configuration on being embedded in roller weares and teares, this substrate microneedle configuration can be taken off, and embed new substrate microneedle configuration again, thereby not influence serviceability.And the substrate microneedle configuration that embeds in the roller draw-in groove can be selected the different micropin of length according to the treatment needs, thereby the micropin of different length is mixed use, and then reaches best therapeutic effect.
Although above this utility model has been done detailed description; but this utility model is not limited thereto; those skilled in the art can make amendment according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
