2.79 mu m Q-switched erbium laser dental instrument

Abstract

The invention discloses a 2.79 mu m Q-switched erbium laser dental instrument. The 2.79 mu m Q-switched erbium laser dental instrument comprises a laser power supply, a laser component, a laser water cooling system, a light guide output system, a gas and water spraying system and a central control system; the laser power supply is used for providing energy to the laser component; the laser component consists of a total-reflection chamber piece, a polarizer, a Q-switched crystal, a xenon lamp, a laser rod, a light condensing chamber, a wave plate and an output chamber piece; the laser water cooling system is used for cooling the laser rod and the xenon lamp in the laser component; the light guide output system is used for conducting laser, and is convenient to operate and use; the gas and water spraying system is used for spraying a mixture of gas and water to a laser acted tooth tissue, and has the effects of reducing the temperature of the tissue and participating laser treatment; the central control system is used for controlling the parameters of the laser power supply, the laser water cooling system and the gas and water spraying system to ensure the coordination work among the subsystems. The 2.79 mu m Q-switched erbium laser dental instrument has pulse Q-switched laser which has short pulse width and high peak power and acts the tooth tissue to improve ablation precision; meanwhile, the thermal damage to peripheral tissues also can be effectively reduced; the pain of a patient can be reduced effectively.

Description

technical field [0001] The invention relates to a 2.79 μm Q-switched erbium laser dental treatment instrument. Background technique [0002] Dental caries is one of the dental diseases with the highest prevalence rate in modern humans, commonly known as "tooth decay". According to incomplete statistics, the total number of caries in my country's population is more than 2 billion, and 90% of these caries have not been treated. Dental caries is caused by the dissolution of calcium and phosphorus in the enamel by plaque to form small holes. Dental caries is very harmful to human health. If the diseased teeth are not treated in time, they will corrode the tooth tissue, and the acid produced will destroy the enamel and damage the tooth cells under the enamel. In severe cases, it will cause systemic infection. [0003] At present, caries treatment mainly includes three processes of caries removal, cavity preparation and filling, among which cavity preparation is a necessary step...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies in the existing dental medical technology, and provide a 2.79 μm Q-switched erbium laser (Cr, Er: YSGG) dental treatment instrument, which changes the Er: YAG laser repetition rate is not high , low efficiency, to replace the role of traditional turbines in cutting tooth hard tissues, effectively remove the smear layer on the surface of the root canal wall, and have a bactericidal effect to improve the effect of root canal treatment, and has short pulse width and high peak power The pulsed Q-switched laser, acting on the tooth tissue can also greatly reduce the thermal damage of the surrounding tissue and effectively reduce the pain of the patient
