Digitally Controlled Dental Ultrasonic Therapy Apparatus

Abstract

The invention discloses a digitally controlled dental ultrasonic therapeutic apparatus which comprises a touch display control unit and a main control unit, wherein the touch display control unit is connected with a touch display screen and connected with the main control unit to realize communication. The main control unit is connected with a digital potentiometer; and through the connection between the digital potentiometer and an operational amplifier, multiple regulation nodes for power control are obtained, and the value adjustment precision is high. A rotation control signal is a PWM digital control signal directly output by the main control unit, and the precision is higher than that of a resistive simulation regulation way. By adopting a way of digital input regulation and digital display for the touch display screen, the operation and control are more flexible and convenient, and the regulation is more accurate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a dental ultrasonic therapy instrument which realizes digital control of power regulation and water volume regulation. Background technique [0002] Dental ultrasonic therapy instrument is a medical device commonly used in hospital stomatology and dental clinics. It is mainly used for oral care (such as cleaning tartar, root grinding, sealing), oral maintenance (such as tooth filling, restoration), pulp disease ( Such as root canal treatment), denture implantation, maintenance, repair, replacement, and periodontitis treatment, etc. As people pay more and more attention to dental health and beauty, more and more people choose to treat and maintain their teeth. [0003] The oral cavity and teeth are parts rich in nerves in the human body, which are very sensitive to touch and pain, especially for dental patients, who are usually accompanied by obvious symptoms of tooth discomfor...

AI Technical Summary

Problems solved by technology

[0004] The existing dental ultrasonic therapeutic apparatuses have low precision in power and water volume control, and are all controlled based on analog or a combination of analog and digital. The power and / or water volume can only be adjusted by knobs or buttons. At this time, it is impossible to display the accurate parameter value of each gear, and the switch between the gears can only be performed according to the doctor's feeling, and it is impossible to locate and fix the parameter output, and it is easy to misuse; The parameter value of each gear is marked, but the parameter value is only a fixed value and analog value set to match the gear, and it is impossible to make finer adjustments in the surrounding value range of the fixed value and analog value, and After long-term use, due to the short life of the device or the wear and tear of the device, the actual output parameters of the instrument are inaccurate compared with the parameter values ​​marked in each gear, and the treatment plan executed by the doctor in the same gear is actually deviated. of
