Monochromatic red light with wavelength of 694.3nm, pulsed output (Joule level) or continuous output (milliwatt level), mainly used for the treatment of ophthalmic diseases.The ruby laser with pulsed output, with power of 0.1 ~ 0.5 joule, is used to close retinal hiatus in the treatment of retinal detachment without effusion in macular area and posterior pole, with efficacy of over 90% and significant effect.Application of 1.0 ~ 2.0 bajaur ruby laser iridectomy, pupillary membrane and secondary glaucoma, closed treatment to remove pigment crystal before sac organization, congenital nuclear and around the nuclear cataract, congenital pupil residual film, trauma, or the shift of the pupil, iris cyst after the surgery, conjunctival pigment disorder, primary closure Angle glaucoma, etc all have a good effect.Ruby laser with output fiber laser marking machine power above 100 joules can treat nevus of pigment, sebaceous glands, verrucous nevus, superficial telangiectasia, etc.
Nitrogen molecular laser
Single-color long wave ULTRAVIOLET light with a wavelength of 337.1nm, pulse output, power of 0.1 ~ 2.0 mm, can be used to treat superficial limited purulent inflammation, infection wounds, tinea capitis, hand, tinea pedis, eczema, neurodermatitis, skin chap, nodal urticaria, vitiligo, furunculosis of external auditory canal, tonsillitis, etc.It can also be used for acupoint irradiation for the treatment of bronchitis, bronchial asthma, neurasthenia and other internal and neurological diseases;In addition, nitrogen molecular laser can also be used as a source of fluorescence detection, diagnosis of early tumors.
Argon ion laser
Lanqing-green light with wavelength of 488nm, 514nm and 514.5nm, continuously output by marking machine, and 1-2 watt argon laser point irradiation can treat traumatic paraplegia, encephalitis sequela, arachnoiditis, poliomyelitis sequela, neurasthenia, bronchial asthma, chronic hepatitis, glycauria, enuresis, etc.
Argon laser with output power of 15 ~ 25 millijoule can close retinal hole and retinal degeneration in early stage of retinal hole.Low power argon laser can be used to treat central serous chorioretinopathy.
Argon laser with output power of several watts can be used to make hemangioma photocoagulation, or to treat synovial cyst, skin gland cyst, lipoma, fibroma, lymphangioma, myofibroma and so on.Argon laser can be used for surgical removal of skin or visceral lesions.
Argon laser can be used as laser endoscope technology to stop the bleeding of stomach and intestine by conducting fiber optic welding machine.In addition, argon-ion laser and argon-ion pumped dye laser (wavelength 6300) can be used for photosensitive diagnosis and treatment of cancer.
Near-infrared wavelength of 1064 nm, pulse output, or continuous output, application of the power of hundreds of joule neodymium-doped yttrium aluminum garnet laser, can cure hemangioma, face against, sebaceous gland tumor, lymphangioma, mucous cyst, labial ministry white spot, etc., to increase the output power also can make the skin and muscle surgery cutting and laryngeal cancer, gastric carcinoma resection.
Neodymium glass laser
With 10600 wavelength of near-infrared light, pulse output or continuous output, he-ne laser is needed for calibration and aiming in treatment. The neodymium glass laser with output power of 15 ~ 20 j can be used to treat chronic wounds, chronic ulcers and soft tissue injuries.
Neodymium glass laser with power of over 100 joules can treat hemangioma, spider nevus, papilloma, pigmented nevus, common warts, corns, vulva leukoplar, basal cell carcinoma, etc.
He CD laser
The continuous output power of 3-16 milliwatts of helium-cadmium laser point irradiation can treat hypertension, dysmenorrhea, acute laryngitis, acute vocal cord inflammation, and so on.Local irradiation can treat neurodermatitis, skin scrapie, nodular urticaria and so on.
The he-Cd laser with an output power of 15-20 milliwatts is introduced into the body cavity through the light guide fiber. With the characteristics of fluorescence display, it can be used for the early diagnosis, biopsy location, and indication of the range of resection of cancer tissues, etc.
