As laser medical treatment becomes more and more widespread, people are dazzled by various types of laser medical treatment, and some advertisements have fooled them into thinking that a laser is omnipotent and can treat various diseases. The fact is that different types of lasers correspond to different laser medical treatments. The medical aspects of different wavelengths and different forms of lasers are also the same. Below are some specific application analyses for some types of lasers.
Gem Laser Series
Monochromatic red light with a wavelength of 694.3nm, pulsed output (joule level) or continuous output (milliwatt level), is mainly used for the treatment of ophthalmological diseases. Apply pulsed ruby laser with a power of 0.1 to 0.5 joules to close retinal tears, to treat retinal detachment without fluid accumulation in the macular and posterior poles, and to seal the holes. The curative effect is more than 90%, and it has a significant effect; 1.0～2.0 joule ruby laser for irisectomy, treatment of pupil membrane closure and secondary glaucoma, removal of anterior lens capsule pigment tissue, congenital nuclear and nucleus around cataract, congenital residual pupil membrane, trauma or after surgery Pupil shift, iris cyst, conjunctival pigmentation, primary angle-closure glaucoma, etc. have good effects. Ruby laser with an output fiber laser marking machine with a power of more than 100 joules can treat pigmented nevi, sebaceous nevi, verrucous nevus, superficial telangiectasia, etc.
Nitrogen Molecular Laser Series
Monochromatic long-wave ultraviolet light with a wavelength of 337.1nm, pulse output, power 0.1～2.0 millijoules, can be used to treat superficial and localized purulent inflammation, infected wounds, tinea capitis, hands, tinea pedis, eczema, neurodermatitis, Chapped skin, prurigo nodularis, vitiligo, external auditory canal boils, tonsillitis, etc.; it can also be used for acupoint irradiation to treat medical and neurological diseases such as bronchitis, bronchial asthma, neurasthenia; in addition, nitrogen molecular laser can also be used for It is the light source of fluoroscopy to diagnose early tumors.
Argon ion laser series
Blue-green light with wavelengths of 488nm, 514nm and 514.5nm, continuous output of the marking machine, application of 1 to 2 watts of argon laser acupoint irradiation can treat traumatic paraplegia, sequelae of encephalitis, arachnoiditis, sequelae of polio, nerves Weakness, bronchial asthma, chronic hepatitis, diabetes, enuresis, etc.
The argon laser with an output power of 15-25 millijoules can seal retinal tears and retinal degeneration before the hole; low-power argon lasers can treat central serous retinal choroidopathy.
The application of argon laser with output power of several watts can be used for photocoagulation of hemangioma, or treatment of synovial cyst, skin gland cyst, lipoma, fibroma, lymphangioma, myofibromas, etc. Argon lasers can be used for surgical removal of skin or visceral lesions.
The argon laser can be used as a laser endoscope technology to stop bleeding in the stomach and intestines through a guided fiber welding machine; in addition, the argon ion laser and the argon ion pump dye laser (wavelength 6300) can be used for photosensitive diagnosis and treatment of new cancers. technology.
YAG laser series
Near-infrared light with a wavelength of 1064nm, pulse output or continuous output, and a neodymium-doped yttrium aluminum garnet laser with a power of hundreds of joules, can treat hemangioma, facial stains, sebaceous adenomas, lymphangiomas, mucous cysts, lip leukoplakia, etc. , Increasing the output power can also be used for the surgical cutting of skin and muscle, as well as the surgical resection of laryngeal cancer and gastrointestinal cancer.
Neodymium Glass Laser Series
Near-infrared light with wavelength of 10600, pulse output or continuous output, helium-neon laser is required for calibration and aiming during treatment. Neodymium glass laser with output power of 15-20 joules can be used to treat chronic wounds, chronic ulcers and soft tissue trauma.
The neodymium glass laser with application power of more than 100 joules can treat hemangioma, spider nevus, papilloma, pigmented nevus, common warts, corns, vulvar leukoplakia, basal cell carcinoma, etc.
Helium Cadmium Laser Series
Violet light with wavelength of 441.6nm and 325nm and long IoT wave ultraviolet light, continuous output power of 3-16 milliwatts of helium-cadmium laser acupoint irradiation can treat hypertension, dysmenorrhea, acute laryngitis, acute vocal cord inflammation, etc.; local irradiation It can treat neurodermatitis, skin pruritus, and prurigo nodularis.
The helium-cadmium laser with an output power of 15-20 milliwatts is guided into the body cavity through the light guide fiber, and the characteristics of fluorescence display can be used for early diagnosis, biopsy positioning and indication of gastric cancer, esophageal cancer, nasopharyngeal cancer, rectal cancer, cervical cancer, etc. Excise the extent of the cancerous tissue, etc.
