Description
Technical field
This utility model relates to beauty treatment instrument, is specifically related to a kind of hand-held twin-stage beauty treatment machine treatment head, belongs to International Classification of Patents A61B18/00 " to human body or transmit surgical instruments, device or the method for on-mechanical form energy from human body " technical field.
Background technology
The ultimate principle of laser beautifying is to utilize human body different tissues pigment that the selectivity Absorption of different wave length laser and the heat effect that the moment impact that laser produced destroys or accumulate longer action time of different pulse widths are removed various speckles, nevus, tumor, hair, and free time addiction such as wrinkle, reach the effect of beauty treatment.The laser beautifying machine of releasing the earliest is the Venus of U.S. Coherent company in the world, and its main performance can see Table 1.From last century end, domesticly begin to utilize Nd:YAG electric-optically Q-switched, the one-level vibration adds one-level amplifies, and the about 800mj of output 1064nm laser through the about 350mj of frequency multiplication output 532nm laser, is causing human body conducting through joint arm.Joint arm efficiency of transmission about 70%.Every price is 100,000 yuan at present.The easy deliquescence of electric-optically Q-switched crystal, the complete machine structure bulky complex is gradually by Cr
4+: YAG transfers Q to replace.Table 1 referring to the description tail.
Summary of the invention
The purpose of this utility model is to improve at prior art, provide a kind of therapeutic effect good, adopt handheld structure compactness, volume-diminished, vibration and amplification to unite two into one, the hand-held twin-stage beauty treatment machine treatment head of good stability.
The purpose of this utility model is achieved through the following technical solutions.
Hand-held twin-stage beauty treatment machine treatment head is provided with the folding Cr of twin-stage in its plastic handle shell
4+: the YAG Q-switched laser, the front end of plastic handle is top for focusing on, and plastic handle is interior, completely reflecting mirror is settled at the rear of Q-switched laser.This completely reflecting mirror is a pair of two 45 ° folding completely reflecting mirror, and wherein: one for fixing a scalable.
Be arranged with the oscillator stage Nd:YAG rod of amplifier stage Nd:YAG rod, xenon flash lamp and bonding in the described Q-switched laser, this xenon flash lamp places between two Nd:YAG rods of oscillator stage and amplifier stage, unified placing in the condenser.
Described bonding oscillator stage Nd:YAG rod, its front portion is provided with the Cr of bonding
4+: the YAG adjusting Q crystal, the front end of adjusting Q crystal connects the white YAG crystal of bonding, and the white crystalline front end of YAG is coated with total reflection film.
Adopt white YAG, Cr4+:YAG, the unified bonding structure of Nd:YAG rod is as oscillator stage.
This utility model hand-held twin-stage beauty treatment machine treatment head has the following advantages:
1, adopts the passive Q-adjusted replacement Pockers cell of Cr4+:YAG electric-optically Q-switched, not only reduce cost greatly, and avoided the deliquescent shortcoming of KD*P in the Pockers cell.Cr4+:YAG is passive Q-adjusted to be still fast switch, and output pulse width is about 8ns.Therapeutic effect is not inferior.
2, adopt high concentration Cr4+:YAG as passive Q-adjusted element.And with white YAG crystal bonding, thereby the length of Cr4+:YAG is increased greatly, and with the Nd:YAG bonding, Cr4+:YAG has very long one section realization water-cooled of can ducking in drink.Thereby under high-energy, realize 5-10 time/second work.
3, adopt a lamp pump double stick scheme.One lamp is placed between two Nd:YAG rods, and place in the unified condenser, so just will vibrate and amplification unites two into one, dwindled volume greatly, make hand-heldly, cancelled joint arm, not only reduce cost, overcome the loss of joint arm simultaneously energy.
4, the distance between oscillator stage and the amplifier stage must be greater than 100mm in order to realize a lamp pump double stick, and we have adopted the folding scheme of two 45 ° of reflecting mirrors (or corner cube prism).When the distance between oscillator stage and the amplifier stage was too small, enlarger added radiation of oscillator stage superfluorescence and amplification to the feedback of oscillator stage, made Cr4+:YAG bleaching ahead of time.Pump energy can not be added, otherwise multiple-pulse occurs.Distance between oscillator stage and the amplifier stage is far away more, and enlarger is more little to the feedback of oscillator stage.Selected distance is the most suitable between 100-250mm, and spacing is excessive, and machine volume is strengthened, and inconvenience is used.
5, folding 45 ° of completely reflecting mirrors, one adjustable, one fixing.Thereby improved stability greatly, improved the quality of machine, also further reduced cost.
Description of drawings
Fig. 1 is the structural representation of this utility model treatment head;
Fig. 2 is the structural representation of the oscillator stage Nd:YAG rod of bonding.
Among the figure: 1, be plated in total reflection film on the white YAG, 2, the white YAG crystal of bonding, 3, the Cr of bonding
4+: YAG adjusting Q crystal, 4, the oscillator stage Nd:YAG rod of bonding; 5, two 45 ° of folding completely reflecting mirrors; 6, amplifier stage Nd:YAG rod, 7, xenon flash lamp, 8, diffuse-reflective cavity, 9, plastic handle, 10, focus on top.
The specific embodiment
Referring to Fig. 1, the treatment head is the core of whole beauty treatment machine, and it comprises plastic handle shell 9, the folding Cr of twin-stage
4+: Y master AG Q-switched laser 8 and focus on toply 10, the structure and the quality of laser instrument 8 itself have determined beauty treatment machine machine performance.Be arranged with the oscillator stage Nd:YAG rod 4 of amplifier stage Nd:YAG rod 6, xenon flash lamp 7 and bonding in the Q-switched laser 8.Bonding oscillator stage Nd:YAG rod 4 its front portions are the Cr of bonding
4+: YAG adjusting Q crystal 3, front end are the white YAG crystal 2 of bonding, and the front end of white YAG crystal 2 is coated with total reflection film 1.Completely reflecting mirror 5 is a pair of two 45 ° folding completely reflecting mirror, and wherein: one for fixing a scalable.
This utility model twin-stage folds Cr
4+: the important improvement of YAG Q-switched laser is as follows:
1, adopt high concentration Cr4+:YAG to replace low concentration Cr4+:YAG to do the Q-switching device: originally low concentration Cr4+:YAG needs crystal length to be～20mm, price is 1200 yuan, now adopts high concentration Cr4+:YAG, needs crystal length only to be～5mm, price is 200 yuan, thereby reduces cost greatly.
2, adopt plain pure YAG (claiming white YAG again) and Cr
4+: the YAG bonding increases the heat radiation volume and solves Cr
4+: YAG heat dissipation problem at work.Plate reflectance coating at the white YAG other end simultaneously, thereby saved completely reflecting mirror, also avoided because the completely reflecting mirror imbalance influences the stability of device, referring to Fig. 2.
This utility model is simple in structure, need not any adjustment structure, does not also just have imbalance, and stability is improved greatly.
3. adopt the Nd of resistance furnace growth
3+: the YAG crystal replaces the crystal of actinobolia growth.The crystal Nd of the former growth
3+Activated ion concentration is obviously than latter height, and lasing efficiency is just high.Adopt same size crystal bar, the synthetic energy of the highest exportable 350mj Q of former device.New device output is greater than the 500mj energy.Because the crystal gain height needn't plate 80% film on the output end face, only depend on 8% reflection of self enough.This not only provides cost savings, and has avoided causing the device instability because rete destroys.
4. on the structure of a lamp pump double stick, adopted two 45 ° of adjustable completely reflecting mirrors originally, facts have proved that the probability of such imbalance increased.Now adopt one to fix, one adjustable, and it becomes the unique adjustable element of entire machine.Be adjusted into aluminium foil increase and decrease screw dead (in fact not had guiding mechanism) admittedly with screw before changing.Thereby make entire machine not have imbalance.Quality, reliability improves greatly.
