Relevant Information About High Speed Handpiece

2024-12-11

High speed dental turbine handpiece is also referred to as dental handpiece or handpiece in dental industry. However, the abbreviation of dental handpiece/handpiece is relatively vague, which is easy to be confused with low-speed handpiece or air scaler handpiece. High speed handpiece is also called air turbine handpiece, fast handpiece air rotor handpiece and midwest handpiece.

High speed dental turbine handpiece is also referred to as dental handpiece or handpiece in dental industry. However, the abbreviation of dental handpiece/handpiece is relatively vague, which is easy to be confused with low-speed handpiece or air scaler handpiece. High speed handpiece is also called air turbine handpiece, fast handpiece air rotor handpiece and midwest handpiece.

In daily oral clinical operation, dental high-speed turbine handpieces are one of the most important treatment tools. The invention of the dental high-speed turbine handpiece can be described as a major breakthrough in dental equipment. It can not only greatly improve the efficiency of oral clinical treatment, but also greatly reduce the pain of patients in the treatment process. Meanwhile, the advent of dental high speed turbine handpiece has also triggered a major global innovation in this area. In just a few years, it has almost completely replaced the traditional form which is operation driven by motor in most of the world wide countries and regions in good economy. It has made a great contribution to the clinical treatment and prevention of dentistry.

 

Since the dental high speed handpiece is very important in the clinical application of dental equipment all over the world. Let's explore all aspects about it together.

 

The dental high speed turbine handpiece / midwest handpiece came out in 1957. It is a kind of high speed transformation medical equipment driven by airflow. Its function is mainly used for cutting tooth, preparing tooth cavity, preparing tooth shape and trimming tooth shape, etc... Although the air-bearing dental high speed turbine has a higher speed and a longer service life, it is rarely used because of the higher noise and lower torque generated during using.

 

The internal structure of the dental high speed handpiece is extremely precise, and its processing accuracy requirements are also very high. The appearance structure is mainly divided into three parts, the head with cap; the handle, and the pipe interface (coupler). The cartridge is built in the head of the air rotor, we called it "the heart of handpiece", "cartridge rotor" or "dental handpiece cartridge" (with a shell), and many people even call it "bearing". There are also several different names in English, such as Rotor, Turbine, Cartridge, etc... The turbine cartridge rotor is the core component and the most precise part of the dental high speed turbine handpiece, which is mainly composed of a shaft, a spindle and a pair of bearings.

 

There are many varieties of dental high speed handpieces. In addition to the differences in quality, there are also a variety of different appearances, as well as a variety of additional functions. For example, there are wrench, push button types; cooling methods include single hole water spray, 2 holes spray, 3 holes spray and 4 holes spray... It distinguishes from lighting function; blowing function; and anti-retraction function; quick coupler; 2 holes and 4 holes, and so on... There are mini head using for the wisdom teeth of children, and some of them can be automatic pressure limiting in other aspects.

 

This handpiece is not only high precision & high performance, but also very "sensitive" dental instruments. Therefore, we must understand its usage and maintenance methods. The current law stipulates that if the medical devices were sold on the market, they must be accompanied by instructions for using. To introduce users for common sense and correct usage method, as well as maintenance method.

 

At present, the government attaches great importance to the management of medical devices. The high speed turbine handpiece belongs to class II in medical documents. All medical devices shall be complied with the legal provisions. When they sold on the domestic market must be registered with the State Food and Drug Administration before they can be sold. And manufacturers must be obtained a medical production license. This is necessary. At the same time, the basis of the relevant laws expounds medical devices must clearly state the manufacturer's full name, detailed address, contact information, medical device’s registration number, manufacturer’s production license number, and production date on the packaging of product. Who fails to sell in accordance with the laws and regulations, or who uses medical devices that do not comply with the laws and  regulations. It is illegal. According to the news, many users (including medical institutions) have been prosecuted and punished by the relevant authorities because they did not know the relevant regulations and bought dental handpieces which did not meet the regulations (the packaging box did not follow the regulations). Everybody needs to know about these rules. 

 

Dental high speed turbine is an indispensable and important device in oral clinical treatment. Nevertheless, it has to be close contact with the saliva, blood, tissue fragments, secretions and dental plaque in the patient’s mouth during the application process. Therefore, the outside and inside, both of them may be contaminated by pathogenic microorganisms in varying degrees. Relevant data displays that one of the diagnosis and treatment items with a high cross infection rate from the diagnosis and treatment of oral diseases.And it occupies an important position in the prevention and control of infection in hospitals. Thus, the internal and external cleaning, disinfection and sterilization of the handpieces are very important.
