Of Nd: Y AG (1 064 nm) laser treatment wine stains is safe and effective in the treatment of hemangioma is best not to use large energy, so as to avoid the body caused by injury [32]. The Angiero [33] (800 ~ 940 nm) diode laser combined with photocoagulation technology, treatment of 136 cases of hemangioma patients, including 134 patients with complete remission, two cases of invalid, no adverse reactions in clinical follow-up. IPL can improve wrinkles, improve texture, irregular color Shen and telangiectasia, including all light aging [34]. For small diameter and shallow vascular lesions with a shorter wavelength (570 am filter) and a smaller pulse width treatment. They should increase the life time of the chip of green laser pointer .
For diameters larger and deeper vascular lesions take a long wavelength (590 nm filter) and a larger pulse width [35]. 755 nm laser treatment of vascular disease mechanism is that the laser can be oxygenated hemoglobin in the blood of selective absorption produces heat so that the vascular coagulation or destruction [36]. Gu Ying [37] reported PDT selective treatment of PWS basic research and clinical results show that the highly selective destructive effect of PDT on superficial dermal capillary network, the high clinical efficacy and side effects. Because the majority of vascular skin diseases in the face, make the patient have a serious psychological trauma, the patient treatment is very high. The long life time of green laser pointer can ensure the good and long time use and operation of the laser pointer for the customer.
Requires not only the elimination of lesions, also requires to achieve cosmetic results (no scarring), namely the treatment of normal skin color and texture [38]. Therefore reduce the side effects of intraoperative and postoperative problems faced by clinicians. Cynergy vascular lesions workstation is equipped with advanced Multi p the lex (the order of the multi-wavelength emission) technology, to launch two different wavelengths specified sequence in the same system of laser (a high-intensity pulsed dye laser, the other is the wavelength of 1 064 nm Nd: YAG laser). 595 nm dye laser and 064 nm pulsed laser in the treatment of vascular disease has made great progress, but still found due to the laser can be excessive or laser wavelength is too short to scar production or penetration depth is difficult enough to achieve the desired effect. Therefore, the long life time of laser pointer should be ensured at first.
Dual-wavelength laser pulse dye laser oxy hemoglobin transformed into hemin makes the target tissue on the Nd: YAG laser absorption rate increased by 3 to 5 times, 1 064-nm laser can reach the low energy density efficacy, thereby reducing the occurrence of side effects, increase security, reduce scar production, improve the efficacy [39]. Multi-wavelength transmission technology combination of PDL and Nd: YAG laser treatment, compared with the treatment of a single wavelength, can achieve better results. In contrast, the PDL, the long-pulsed 064 nm Nd: YAG laser and KTP adjustable pulse width 532 nm wavelength treatment usually takes 2 to 3 treatments, in order to achieve similar efficacy and low side effect rate [40]. When the factory manufactures green laser .
Make sure the location of the nanoparticles and then the laser irradiation. Researchers at the University of Wake welfare Waters has made new progress in the use of laser treatment of tumors. They used magnetic resonance imaging device successfully identified the location of carbon nanotubes into the tumor tissue after laser irradiation and heating them, thereby undermining the tumor tissue. Laser heating and destruction of tumor tissue is not a new technology, laser induced thermal therapy (LITT) has been used. Laser induced thermal therapy, however there is a problem, nanoparticles able to absorb the laser energy is injected into the patient's body, people can not track their footprint, it is difficult to know exactly whether nanoparticles into the tumor tissue. It is the 3000 hour life time of laser module of green laser led .
