Commonly laser treatmontor include semiconductor laser, ammonia-neon (He-Ne) laser, nitrogen molecular laser, hydrogen ion laser, ammonia-cadmium laser, Nd-YAG laser, carbon dioxide laser and so on. These lasers are applied in different clinics in the low, medium, and high energy ranges, respectively.
Low and medium energy lasers can be applied to the following clinical treatments:
1. Internal medicine diseases: essential hypertension, hypotension, asthma, pneumonia, bronchitis, gastrointestinal dysfunction, hepatitis, rheumatoid arthritis, tumor patients with radiotherapy or chemotherapy response, leukopenia, neurasthenia, concussion sequelae, nerve headache, radiculitis, syringomyelia, facial neuritis, trigeminal neuralgia, pediatric cerebral palsy, enuresis, etc.
2. Surgical diseases: chronic wounds, chronic ulcers, pressure sores, burn sores, paronychia, furuncle, carbuncle, lymphadenitis, phlebitis, vascular occlusion, vasculitis, tenosynovitis, synovitis, periarthritis of shoulder, humeral epicondylitis, soft tissue contusion, sprain, fistula, prostatitis, etc.
3.Gynecological diseases: dysmenorrhea, adnexitis, ovarian dysfunction, breech metastasis, vulgenitis, vaginitis, sexual diseases, etc.
4.Dermatological diseases: eczema, dermatitis, alopecia areata, herpes zoster, skin pruritus, neurodermatitis, herpes simplex, etc.
5.Oral diseases: chronic lipilitis, map tongue, glossitis, tongue nipple peeling, traumatic oral ulcer, recurrent stomatitis, drug allergic stomatitis, herpetic stomatitis, irradiation of tooth surface enamel, can enhance the ability of anti-decalcification, has the effect of preventing dental caries.
6.Otolaryngology diseases: ear soft periosteal inflammation, chronic rhinitis, allergic in taking inflammation, atrophic rhinitis, pharyngitis, tonsillitis, laryngitis, deafness, tinnitus, etc.
High-strength energy laser can be applied in the following clinical treatments:
1.Output power is 10-30W, acute disease patients can often use for less than 10W, and chronic patients can be used for about 20W. Treatment of diseases including wound infection, chronic ulcers, pressure ulcers, myofibrolitis, tenosynovitis, bursitis, external epicondylitis, sprain, chronic diarrhea, wet arthritis, neurodermatitis, scleroderma, tuberous, itchy rash, eczema, tinea hand, facial neuritis, temporal joint dysfunction, dental allergy, dental injection, simple rhinitis, vulvar pruritus adnexitis, pelvic inflammatory diseases, cervical cancer, enuresis, etc.
2.Output power 30-80W, the treatment of diseases including pigment nevus, melanoma, hemangioma, bright red spot nevus wart nevus, papilloma, ordinary wart, senile keratosis, chicken eye, skin cancer in situ, basal cell carcinoma, squamous cell cancer, lip cancer, tongue cancer, tongue cancer, tongue lip mucus cyst, hypertrophic rhinitis, epistaxis, son official neck erosion, cervical cancer, etc.
3.The output power is 100-300W, which is used as a "light knife". Clinically, carbon dioxide "light knife" has been used for surgery in the neck chest, limbs, body surface and other parts, most of which are used for tumor resection. Otolaryngology is used for tonsillectomy, total epiosteectomy, etc. In burns it is used for the removal of scab sts or scarring.
