During the use, the lens switching rotary drum is rotated, a plurality of matching grooves are formed on the periphery of the drum wall of the switching rotary drum, and the corresponding lens is turned into the laser main light path when rotating to a certain angle, therefore, the most proper treatment spot is selected according to the shape and area of the skin to be treated, the accurate treatment is realized and the side effects are reduced.
Description
Technical field
The present invention relates to a kind of Optical devices, more particularly, to a kind of laser facula adjusting means.
Background technology
Nd：YAG crystal is current combination property laser crystal the most excellent.Optical maser wavelength 1064nm, the army of being widely used in
Thing, the industry such as industrial and medical.1064nm Nd：YAG laser therapeutic apparatus have been widely used the more than ten years in aesthetic medicine field.
1064nm Long Pulse LASER is the effective means for the treatment of vascular conditions.It is rich in hemangioma and skin red blood streak
HbO2 Oxyhemoglobins have stronger absorbability to 1064nm.It is converted into heat after hemoglobin absorption laser light energy in target tissue
Can, produce photo-thermal consolidation, vascular endothelial cell thus produces necrosis, degeneration, thus reaching by laser therapy hemangioma
Purpose with red blood streak.
Laser depilation：The treatment principle of laser depilation is based on selective photothermolysis, has due in hair follicle and hair shaft
Abundant melanin, melanin is distributed between the cell of ball top substrate, and shifts in the structure of hair shaft.Laser depilation is
Depilation treatment is carried out for target with melanin, absorbs certain wave in target and its carrier (hair follicle and perifollicolar tissue)
After the huge energy of long (1064nm) laser beam, temperature drastically raises, and leads to hair follicle and perifollicolar tissue to be destroyed, hair
Send out and lose primitive environment, and then forever dispelled.Because light beam only works to melanin, produce thus without normal tissue
Any untoward reaction, does not more interfere with the normal function of sweat gland.
With, in red blood streak and laser depilation in laser therapy hemangioma, skin, being accurately directed to skin region in need for the treatment of
Domain, reduces the impact to surrounding skin particularly important as far as possible.Therefore, the laser facula size adjusting device of brief and practical is reality
Application brings convenience and therapeutic potential.But the spot size adjusting means still not having at present a kind of therapeutic instrument is succinct enough,
Practical, durable.
Content of the invention
The technical problem to be solved is to provide a kind of big ditty of simple for structure, practical, durable laser facula
Regulating device.
The present invention is to solve above-mentioned technical problem to adopt the following technical scheme that：
A kind of laser facula size adjusting device, switches rotating cylinder, described lens switching rotating cylinder and equipment machine including lens
Frame axle connects, and is provided with some hole axles and switches parallel saturating of tube rotaring axis with described in the concentric circumferences that described lens switch rotating cylinder
Mirror through hole, is fixedly installed the different lens of focal length in described lens through hole, and the axis of described lens is cut in described lens
Change on the same concentric circular cylinder of rotating cylinder；Described lens switch rotating cylinder outer circumference surface be provided with angle positioning device it is ensured that
There are the axis of a described lens through hole and the dead in line of laser main optical path each time during rotational positioning.
Described angle positioning device can be by the hoodle mechanism fixed with equipment rack and the hoodle with hoodle mechanism
Some grooves being arranged at described lens switching rotating cylinder outer circumference surface that position matches are constituted, described lens switching rotating cylinder rotation
In when hoodle embeds one groove positioning each time, have the axis of a corresponding described lens through hole and described laser master
The axis location of light path overlaps；Described hoodle mechanism include with described matching grooves setting hoodle, be arranged at after hoodle
Elastic supporter and fairlead, described fairlead is fixedly connected with equipment rack.
Protective cover and rear protective cover before the two ends that described lens switch rotating cylinder are preferably respectively arranged with, in forward and backward guarantor
The guard shield position corresponding with described lens through hole offers through hole.
During use, relay lens switches rotating cylinder, and switch rotating cylinder barrel has multiple coupling grooves for one week, goes to certain angle
Degree, angle positioning device will position lens switching rotating cylinder, and now corresponding lens are called in laser main optical path, shoot laser
Spot size just changes therewith, the shape of the skin so treated as needed and area, selects most suitable treatment hot spot.
And angle positioning device can be specifically made up of hoodle mechanism and some detents, when the rotation of a certain detent
To hoodle authority match position when, hoodle below elastomeric material effect under coupling embed this detent in, now have
The axis of one corresponding described lens through hole is overlapped with the axis location of described laser main optical path；In rotation, hoodle coupling is embedded
Different detents, can switch the entrance laser optical path of the lens of different focal.Realize precisely treating, reduce sending out of side effect
Raw.
