Dental handpiece repair kit

The structure of the dental handpiece

Dental handpieces are classified into two types: ball bearing type and air bearing type, according to the different working methods of the bearings used.

Ball bearing type high-speed handpiece is mainly composed of handpiece, handle and dental handpiece connector.

1. The internal structure of the machine head

The vortex core rotor is the core component of the machine head. It is composed of a bearing, a wind wheel and a mandrel. There are upper and lower miniature bearings in the machine head. The bearing is cushioned with an O-shaped rubber ring to keep the bur at high speed. Radial and axial concentricity during rotation, and reduces operating noise and vibration.

2. Clamping method of bur

There are various ways for the machine head to clamp the bur. In the early days, the reed-type clamp was used, that is, there were 3 evenly divided bow-shaped reeds in the mandrel. The bur handle is inserted into it, and the reed is deformed by force to clamp the needle handle.

Nowadays, screw-type and pressing-type bur clamping methods are mostly used. The clamping sleeve of this dental handpiece has an elastic three-lobed clamping spring. The clamping spring is in the shape of a hammer and has three axial grooves. Or press the top spring to open or lock the clamp spring to hold the bur.

3. Spray structure

There is a water pipe and a gas pipe at the tail of the turbine dental handpiece. The water and gas are mixed at the outlet of the handpiece and sprayed out from the spray hole in the form of a mist.

4. Dental handpiece connector

The dental handpiece connector is the connection between the handpiece and the output hose of the main unit. The main air flow that drives the rotation of the dental handpiece wind wheel and the branch air that generates atomization enter the main air hole, branch hole and water hole of the dental handpiece connector through the pipeline respectively. Dental handpiece. There are two ways of connection between the handpiece and the handpiece connector: one is with a fixed lock nut on the handpiece connector, and the other is with a quick-release connector.

Prohibited items:

1.Be sure to replace the bur or attach and detach the dental handpiece after the rotation of the motor has completely stopped. (May cause injury.)

2.After the treatment, please clean it immediately, lubricate it with oil (do not lubricate the motor with oil), and sterilize it at high temperature and high pressure. (May cause blood to clot inside the dental handpiece.)

3.In the environment of electromagnetic waves, malfunction may occur. Do not place this product near machines that generate electromagnetic waves.

Maintenance of Dental Autoclave Sterilizer

Sterilizer is an instrument that can kill or remove all microorganisms on the transmission medium, including bacterial spores and non-pathogenic microorganisms. There are usually three methods: moist heat sterilization, dry heat sterilization, and chemical sterilization.

The Dental Autoclave Sterilizer consists of a water tank, a sterilization chamber, a thermal insulation layer, a door body, a pipeline system, a control system and an outer casing. The sterilizer should have a 121°C or 134°C setting program. The sterilization temperature should not exceed the set temperature of 4 °C; the temperature difference between any two points should not exceed 2 °C; the performance of other products should meet the technical requirements of registered products. Doing good maintenance and maintenance is actually the best way to prolong the life of each instrument and reduce the incidence of failures. There is no shortage of sterilizers. After all, long-term sterilization of sterilizers is also necessary. Better maintenance and maintenance are required.

1. Daily maintenance
1.1 Scrub the exterior of the sterilizer and keep the sterilization chamber clean and dry every day
1.2 Cleaning of the filter screen, the filter screen is easily attached to various fiber debris and sediments, which will seriously affect the speed of vacuuming and the smoothness of condensed water treatment
1.3 Check whether the rubber ring is damaged or not and whether the air inlet is blocked. It is best to apply talcum powder on the rubber strip after using it every day to prolong the service life of the rubber strip.
1.4 Check whether the pointer of the pressure gauge can return to "0", and the degree is not accurate
1.5 After the sterilization work is over, cut off the power supply, turn off the power supply, and turn off the steam power supply.

2. Regular maintenance:
2.1 Clean the inner wall of the sterilization pot with neutral detergent every week; remove the remaining water inside the boiler and close the valve in time
2.2 Pull the handle of the safety valve in the inner chamber of the sterilizer once a month and flush it with steam to prevent its action from malfunctioning. At the same time, it should be noted that the sterilization room must be thoroughly descaled, repaired and maintained at least once a month. When descaling, properly mix water and descaling agent according to the principle of 1:100, and then perform descaling after mixing evenly. After 10 minutes, clean the container and then wipe the container with a lint-free cloth to keep the container dry. The sterilization room and the cleaning car can also be cleaned according to the above method, and the stainless steel parts should be wiped with gauze soaked in paraffin oil.
2.3 Every quarter, let the pressure sterilizer manufacturer carry out large-scale maintenance and repair work on the instrument. For example, check whether the door panel of the autoclave is flat, and remove the cover panel in the autoclave. At the same time, rust should be removed for the rusted parts, and high temperature lubricating oil should be added to the pressure sterilizer.
2.4 Remove the sealing strip every half a year, clean it with soapy liquid, wipe it with alcohol and dry it, and then put it back into the sealing tank; descale the steam generator; clean the air inlet and water inlet pipe filters; And steam generator pressure gauge sent to the Measurement Technology Testing Institute for testing and retain the test certificate.
2.5 The sterilizer and the safety valve of the steam generator are sent to the Special Equipment Supervision and Inspection Institute for inspection once a year and the inspection report is retained.

Whether it is daily maintenance or regular maintenance, it is an opportunity for the instrument to rejuvenate. In the day-to-day work, it can also feel a refreshing maintenance, which can not only prolong the service life, but also stabilize the way it works.  ----From Ruito dental equipment
