Lens with different focal lengths are fixedly arranged on the lens through holes. An angle location device is arranged on the outer circumferential surface of the lens switchover rotary drum, and therefore an axis of one of the lens through holes is guaranteed to be coincided with the axis of a laser mina path. While using, a user can rotate the lens switchover rotary drum. And a plurality of matched grooves are arranged on the wall of the lens switchover rotary drum. The corresponding lens is regulated into the laser mina path after the lens switchover rotary drum is rotated in a certain angle. According to shape and size of skin which needs curing, the user can choose the best suitable light spot to achieve accurate cure and reduce occurrence of side-effect.
Description
Technical field
This utility model relates to a kind of Optical devices, relates in particular to a kind of laser facula adjusting device.
Background technology
The Nd:YAG crystal is the most excellent laser crystal of present combination property.Optical maser wavelength 1064nm is widely used in military affairs, industry and the industry such as medical.1064nm Nd:YAG laser therapeutic apparatus has been widely used the more than ten years in the aesthetic medicine field.
The 1064nm Long Pulse LASER is the effective means for the treatment of vascular conditions.The HbO2 Oxyhemoglobin that is rich in hemangioma and the skin red blood streak has stronger absorbability to 1064nm.Be converted into heat energy behind the hemoglobin absorbing laser luminous energy in the target tissue, produce the photo-thermal consolidation, vascular endothelial cell produces necrosis, degeneration thus, thereby reaches the purpose by laser therapy hemangioma and red blood streak.
Laser depilation: the treatment principle of laser depilation is based on selective photothermolysis, owing in hair follicle and the hair shaft abundant melanin is arranged, melanin is distributed between the cell of ball top substrate, and shifts in the structure of hair shaft.Laser depilation is the treatment of losing hair or feathers take melanin as target, after target and carrier (hair follicle and hair follicle surrounding tissue) thereof have absorbed the huge energy of specific wavelength (1064nm) laser beam, temperature sharply raises, cause hair follicle and hair follicle surrounding tissue to be damaged, hair loses primitive environment, and then is forever dispelled.Because light beam only works to melanin, therefore can not produce any untoward reaction by normal tissue, more can not affect the normal function of sweat gland.
In with laser therapy hemangioma, skin, in red blood streak and the laser depilation, accurately for the skin area of needs treatment, reduce the impact of surrounding skin particularly important as far as possible.Therefore, succinct practical laser facula size adjusting device is that practical application brings convenience and treatment meaning.But still there is not a kind of spot size adjusting device of therapeutic instrument enough succinct, practical, durable at present.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple for structure, practical, durable laser facula size adjusting device.
This utility model is to solve the problems of the technologies described above to adopt following technical scheme:
A kind of laser facula size adjusting device, comprise that lens switch rotating cylinder, described lens switch rotating cylinder and equipment rack is coupling, the concentric circumference of switching rotating cylinder at described lens is provided with some holes axle lens through hole parallel with described switching tube rotaring axis, be fixedly installed the different lens of focal length in described lens through hole, the axis of described lens switches on the same concentric circular cylinder of rotating cylinder at described lens; The outer circumference surface that switches rotating cylinder at described lens is provided with angle positioning device, and the dead in line of axis and the laser main optical path of a described lens opening is arranged when guaranteeing to rotate each time the location.
Described angle positioning device can be by somely being arranged at the grooves that described lens switch the rotating cylinder outer circumference surface and consisting of with the fixing hoodle mechanism of equipment rack and with the hoodle position of hoodle mechanism is complementary, described lens switch when hoodle embeds described groove location each time in the rotating cylinder rotation, have the axis of the described lens opening of a correspondence to overlap with the axis location of described laser main optical path; Described hoodle mechanism comprises the hoodle that arranges with described groove coupling, be arranged at elastic supporter and fairlead behind the hoodle, and described fairlead is fixedly connected with equipment rack.
Protective cover and rear protective cover before the two ends of described lens switching rotating cylinder preferably are respectively arranged with, the position corresponding with described lens opening at forward and backward protective cover offers through hole.
During use, relay lens switches rotating cylinder, switch a plurality of coupling grooves that have in a week of rotating cylinder barrel, forward certain angle to, angle positioning device will switch rotating cylinder by positioning lens, and this moment, corresponding lens were called in the laser main optical path, and the spot size of shoot laser just changes thereupon, shape and the area of the skin for the treatment of are selected only treatment hot spot so as required.
And angle positioning device can specifically be made of hoodle mechanism and some detents, when a certain detent rotates to the position of hoodle mechanism coupling, hoodle mates under the elastomeric material effect of back in this detent of embedding, and have the axis of the described lens opening of a correspondence to overlap with the axis location of described laser main optical path this moment; Hoodle coupling embeds different detents in the rotation, can switch different focal lens enter laser optical path.Realize precisely treatment, reduce the generation of side effect.
