Description
Technical field
This utility model relate to a kind of utilize laser to transmit surgical instruments from the energy of on-mechanical form to human body or device, be specifically related to a kind of laser therapeutic head exporting circular uniform light spots.
Background technology
1064nm/532nm adjusts Q nd yag doubled-frequency laser therapy apparatus to be widely used at beauty treatment fields, is mainly used in dispelling skin green grass or young crops, blue birthmark, nevus fuscoceruleus ophthalmomaxillaris and dark color and tatoos.And existing therapy apparatus output beam is radiated on skin, be characterized in that central energy density is maximum, when expanding to edge from beam center, energy density diminishes gradually, and Laser beam energy distribution is uneven, when treating, skin Stimulated Light irradiates uneven easy injured skin.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is: provide a kind of laser therapeutic head exporting circular uniform light spots, and the problem that can effectively avoid spot energy distribution uneven realizes the even output of hot spot, prevents injured patient's skin.
The technical scheme that this utility model adopts for its technical problem of solution is:
The laser therapeutic head of the circular uniform light spots of described output; comprise lens barrel; described lens barrel one end connects joint arm; the lens barrel other end connects centring ring; lens barrel inside arranges holographic grating, condenser lens and cover glass in turn along laser light source transmit direction; in lens barrel, corresponding holographic grating, condenser lens and cover glass arrange holddown groove respectively, and former three is fixed in corresponding holddown groove respectively by partition.
Holographic grating, condenser lens and cover glass is set gradually in this utility model lens barrel; be placed in the direction of advance of laser light source transmitting; during use, centring ring is pressed close to human body position to be treated, accurate positioning; the Gaussian Beam joint arm that laser instrument is launched enters lens barrel; through holographic grating, beam energy is redistributed, and focuses on through condenser lens; by cover glass, gauss laser beam is shaped conglobate flat top beam.
Gaussian beam is through holographic grating, be divided into some tiny light beams, energy is skewness also, place condenser lens below, make the parallel light focusing of the same angle sent by each tiny light beam on the focal plane of condenser lens, the angle of the light sent due to each tiny light beam is continuous distribution, therefore focal plane is formed the energy tiny hot spot of the same size of continuous distribution, organizes conglobate uniform light spots.
The tiny light beam of the larger formation of grid stroke groove density is more, in Laser beam propagation, energy loss is less, adopt holographic grating, ghost line and satellite line can not be produced during work, there is not the defects such as the irregular or burr of the microcosmic of ruled grating cutting, veiling glare is far smaller than the veiling glare of ruled grating, and the uniformity therefore obtaining hot spot is better.
Wherein, preferred version is:
Described condenser lens adopts non-spherical lens, and non-spherical lens has better radius of curvature, can maintain good lens error correction.
The described lens barrel other end is fixedly connected with elastic ring one end, and elastic ring connects centring ring by vertical rod, and vertical rod is separated out a segment distance by between condenser lens focal plane and human body therapy position, prevents hypotelorism burn treatment area skin.
Described elastic ring is threaded with lens barrel, elastic ring is connected to centring ring by vertical rod, the length of vertical rod determines the distance at condenser lens focal plane and human body therapy position, in therapeutic process, the different state of an illness needs to adopt different irradiation distances, and different irradiation distance needs to change different elastic rings, to adapt to treat needs, be threaded convenient disassembly, time saving and energy saving.
Compared with prior art, this utility model has following beneficial effect:
This utility model structure is simple, and use safety, the problem that can effectively avoid spot energy distribution uneven, realizes the even output of hot spot, prevent injured patient's skin.During use, centring ring is pressed close to human body position to be treated, accurate positioning, the Gaussian Beam joint arm that laser instrument is launched enters lens barrel, then carries out the redistribution of energy through holographic grating, laser beam is made to be evenly distributed on the focal plane of lens through condenser lens again, namely treat face, light spot energy is even, avoids because being applied to energy on skin uneven and cause skin heat to damage, then the phenomenon of chromogenesis calmness, improves laser therapy safety coefficient.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is described further:
As shown in Figure 1-2; the laser therapeutic head of the circular uniform light spots of output described in the utility model; comprise lens barrel 1; described lens barrel 1 one end connects joint arm 2; lens barrel 1 other end connects centring ring 3; lens barrel 1 inside arranges holographic grating 4, condenser lens 5 and cover glass 6 in turn along laser light source transmit direction, and in lens barrel 1, corresponding holographic grating 4, condenser lens 5 and cover glass 6 arrange holddown groove respectively, and former three is fixed in corresponding holddown groove respectively by partition 7.
Wherein, condenser lens 5 adopts non-spherical lens, and non-spherical lens has better radius of curvature, can maintain good lens error correction; Lens barrel 1 other end is fixedly connected with elastic ring 8 one end, and elastic ring 8 connects centring ring 3 by vertical rod 9, and vertical rod 9 is separated out a segment distance by between condenser lens 5 focal plane 11 and human body therapy position, prevents hypotelorism burn treatment area skin; Elastic ring 8 is threaded with lens barrel 1, elastic ring 8 is connected to centring ring 3 by vertical rod 9, the length of vertical rod 9 determines the distance at condenser lens 5 focal plane 11 and human body therapy position, in therapeutic process, the different state of an illness needs to adopt different irradiation distances, and different irradiation distance needs to change different elastic rings 8, to adapt to treat needs, be threaded convenient disassembly, time saving and energy saving.
This utility model structure is simple, and use safety, the problem that can effectively avoid spot energy distribution uneven, realizes the even output of hot spot, prevent injured patient's skin.Holographic grating 4, condenser lens 5 and cover glass 6 is set gradually in lens barrel 1; be placed in the direction of advance of laser light source transmitting; during use, centring ring 3 is pressed close to human body position to be treated, accurate positioning; the Gaussian beam 10 that laser instrument is launched enters lens barrel 1 through joint arm 2; when holographic grating 4, beam energy is redistributed, and focuses on through condenser lens 5; by cover glass 6, Gaussian beam 10 is shaped conglobate flat top beam.
Gaussian beam 10 is when holographic grating 4, be divided into some tiny light beams, energy is skewness also, place condenser lens 5 below, make the parallel light focusing of the same angle sent by each tiny light beam on the focal plane 11 of condenser lens 5, the angle of the light sent due to each tiny light beam is continuous distribution, therefore focal plane 11 is formed the energy tiny hot spot of the same size of continuous distribution, organizes conglobate uniform light spots.
The tiny light beam of the larger formation of grid stroke groove density is more, in Laser beam propagation, energy loss is less, adopt holographic grating 4, ghost line and satellite line can not be produced during work, there is not the defects such as the irregular or burr of the microcosmic of ruled grating cutting, veiling glare is far smaller than the veiling glare of ruled grating, and the uniformity therefore obtaining hot spot is better.
