Ultrasonic dental unit without tooth damage

Abstract

The invention discloses an ultrasonic dental unit without tooth damage. The ultrasonic dental unit without tooth damage comprises a handle case and an energy converter arranged in the case, wherein the front end of the energy converter is fixedly connected with the first end of an amplitude change rod; the second end of the amplitude change rod extends to a position outside the case; the second end of the amplitude change rod is connected with a work point for cleaning teeth; the work point at least comprises a first work body and a second work body; the first work body and the second work body are integrally shaped or fixedly connected into a whole to form the work point with regions with different hardness. The ultrasonic dental unit also comprises an image collecting device, wherein theimage collecting device is connected with the tooth cleaning handle through a shape-changeable connecting device. Through the structural design of the amplitude change rod, the design of the work point, and the improvement of an image pick-up device and connection device, the safety and the comfort degree of the tooth cleaning equipment are integrally improved, so that the tooth cleaning handle can be more easily operated and used by an ordinary user; the healthy tooth caring mode of tooth cleaning can be completed in a self-help way at home.

Description

technical field [0001] The invention belongs to the field of medical dental cleaning instruments, and in particular relates to an ultrasonic tooth cleaning machine which does not damage teeth. Background technique [0002] The dental scaler is a special equipment for cleaning teeth, and it is a dental cleaning appliance used to remove dental calculus, smoke spots, bacterial plaque, etc. The ultrasonic scaler uses the high-frequency, high-energy vibration generated by ultrasonic waves to crush and fall off the calculus and stains on the surface of the teeth through the smooth working head on the handle of the ultrasonic scaler. Ultrasonic scalers generally include a power supply, a host, a handle and a foot switch. An ultrasonic generator is installed in the host, the working head is installed on the horn at the front end of the handle, and an ultrasonic wave connected to the ultrasonic generator through a cable is installed in the handle. Transducer, the ultrasonic transduc...

AI Technical Summary

Problems solved by technology

When the working tip of the dental scaler is in use, the working tip is in contact with the teeth to perform operations such as scraping, grinding, drilling, and root canal cleaning. The working tip is easy to be damaged and worn. Once the working tip is damaged Or wear, it is necessary to replace the entire scaler tip, the cost is high

Moreover, its metal material is not conducive to the user's own toothwashing operation. Although the amplitude of ultrasonic vibration is very small, people have a natural sense of fear due to the characteristics of the metal itself, so that people naturally reduce the frequency of toothwashing, especially after For repaired or implanted dentures, scratches will appear to allow plaque to adhere to the teeth after cleaning with metal working tips, which is contrary to the therapeutic principles of tooth cleaning

[0005] At the same time, the existing working tip and the horn of the dental scaler are connected in the outer shell of the handle, and only professional fixing tools can be used to fix or replace the working tip, which is very inconvenient to operate

At the same time, because the connection part is deep in the shell, the connection part cannot be cleaned effectively. After a period of use, a large number of bacteria will grow at the interface, which is not conducive to the health of users.

[0006] Moreover, if the user cleans his teeth at home, he needs to monitor the cleaning process comprehensively, and observe the cooperation between the working tip and the teeth at all times. However, the existing camera equipment of the tooth cleaning handle is not applied to the patient himself. The scenario of cleaning one's own teeth is designed, and the angle and position of the image acquisition cannot meet the user's requirements for observing the teeth.

[0007] The above factors have seriously restricted the dental cleaning machine from entering the homes of ordinary people, reducing the convenience and safety of the dental cleaning process.
