Described concentrating element is to form the periodically optical element of spot array, is made up of a main micro optical element at least.

The scope of the formed periodicity array of light spots of described concentrating element is 20～1000.

The focal distance f scope of described concentrating element is 5mm～100mm.

The profile of described concentrating element is circular, tetragon, or hexagon.

Adopt encapsulation technology with the unified encapsulation of optical filter, aperture diaphragm and concentrating element, also can be divided into two sections or three sections encapsulation, every section comprises an element or two elements, utilizes screw thread to twist and lumps together.

The material that above-mentioned encapsulation is adopted is metal or alloy.

The advantage that this utility model is compared with prior art had is:

(1) medical beauty treatment device of the present utility model is to adopt concentrating element to realize laser beam is divided into the focal beam spot array, the energy that is laser has carried out beam splitting, utilize this spot array to carry out medical and beauty treatment, use this device not need directly to contact skin, adopt the collagen of the heat effect destruction skin of focal beam spot, it is regrowed form the skin of new youth;

(2) medical beauty treatment device focused spot size of the present utility model is a micron dimension, hot spot only destroys by about 20% skin collagen matter tissue in the area for treatment, the skin histology of remainder is not destroyed, therefore the collagen of the youth that ruined collagen can ramp Cheng Xin can be finished regenerating of whole area for treatment skin by treatment repeatedly;

(3) medical beauty treatment device of the present utility model adopts the concentrating element of periodicity array of light spots can produce tens to the individual independently focal beam spot array of hundreds of, than existing single-point laser scanning technique, has improved the efficient and the practical application of device;

(4) medical beauty treatment device of the present utility model is simple in structure, and cost is low, can satisfy individual even family of small hospital needs, is convenient to promote.

(5) medical beauty treatment device of the present utility model is contactless for skin when actual therapeutic, can avoid injured skin or cause scar.

Description of drawings

Fig. 1 is the light path sketch map that utilizes the laser medical beauty treatment device of focal beam spot;
