laser pointer will enhance learning outcome

Irradiated by laser treatment machine 3, every part of 3 minutes, day 1, treatment 6 times, surgical openings began to shrink, the wound clean, the surgeon asked to stop using plaster traction therapy methods to help wound healing, but three days wound appeared purulent discharge again, and then continue to use the laser 11, the wound gradually reduced, the skin gradually grow, basic wound healing, in the rush to hospital, no further treatment. Example 2: The patient Zhang  , patients Wang  , No. 34115 and 34118,2 physical therapy patients in cataract surgery the next day, ptosis, eyelid closure, the laser treatment, 1 patient treated three times, and 1 treatment 1 After the eyelids open, the patient recovered, which is dominated by the movement of the orbicularis oculi muscle fibers by nerve damage, impaired neurological recovery after treatment.  laser pointer  should use the typical battery.
In recent years, the semiconductor laser in medical applications is the development of gallium arsenide semiconductor material gallium arsenide laser, the wavelength of 980nm, the wavelength of the laser as gallium arsenide in the human body within the window, deep penetration, power, helium-neon laser heat than obvious damage to the skin than the He-Ne laser is small, the analgesic effect was, the mechanism is able to promote within the body produces morphine-like substances, play analgesic effect on the nervous system, can promote nerve regeneration, patients with peripheral facial neuritis, treatment, basic recovery in January, although no infection on surgical wound sterilization and antibacterial effect, but can increase immunity, enhance the activity of the number of phagocytic cells and enhance immune globulin concentration, and promote local blood circulation, accelerate metabolism and improve the local nutrition, to promote absorption of inflammatory substances in output, and thus play inflammation, swelling effect. The battery of laser pointer  should be kept away from the water.laser pointer   can facilitate teaching
laser irradiation, rats 31. GaAs semiconductor laser wavelength 830nm, power continuously adjustable 0-500mW, measured before each use Laser Power Meter Laser power output. Irradiation spot diameter 0.6cm2, targeting nerve anastomosis each exposure 10min, A, B, C, D rats irradiated laser energy density of 0Jcm2, 10.62Jcm2, 21.23Jcm2 and 31.85Jcm2. Histological examination: 2,4,6,8 weeks after the group 3 rats were sacrificed to observe the sciatic nerve healing, and drawn for routine pathological staining nerve fibers and Bieschowsky Act Weil iron alum hematoxylin staining marrow sheath staining nerve fibers and myelin at different times of change.
Nd: YAG laser treatment of bladder tumor volume can be expanded from 1.5cm2 to 5cm2, the number can be expanded from 2 to 4 treatment to 7 to 8, and some even up to 10 tumors, depending on patient circumstances. Quartz fiber radiation angle difficult, it can swing the direction of cystoscopy, or reduce the injection of water, the upper part of the pubic or anal pressure refers to the patient to raise the bottom of the bladder neck or adjust the operating table tilt angle so that the vertical optical angle to meet the tumor's requirements. Of the ureteral orifice larger than 5cm2 tumor, master can be applied after laser treatment. In the laser cystoscope photodynamic therapy. The finished products of laser pointer  is stored in the specific area. laser pointer   will enhance learning outcome
