Oral Therapy Handpieces Daily Use and Maintenance Tips To Extend The Service Life Of Your Handpieces
The "mobile phone" of the stomatology department refers to the "dental handpiece", a therapeutic instrument held by the doctor, which is an essential tool for oral treatment of patients. It is mainly divided into high-speed handpieces and low-speed handpieces. The speed of high-speed handpiece reaches 350-420,000 revolutions per minute, mainly used to do treatment and repair such as holes, cutting and so on. Low-speed handpiece is divided into straight machine and bending machine; The straight machine is used for polishing and polishing, which is treated outside the mouth, and the bending machine is treated inside the mouth.
Oral treatment fast handpiece direct contact with the patient's mouth, easy to produce hospital risk, and the water and gas pipeline is easy to block, so after treatment, daily cleaning and disinfection and maintenance should be done to extend the service life, prevent unnecessary failures, and ensure the safety of clinical use.
●Why need to disinfect dental handpieces?
Because dental handpieces mainly cause cross infection through the following ways:
1. Surface contamination caused by contact with the patient's saliva, blood and debris during the operation of the dental handpiece in the mouth;
2. Air pollution caused by aerosol and droplets of pathogenic microorganisms entering the air during high-speed rotary cutting of dental handpieces;
3. The negative pressure formed when the high-speed turbine of the handpiece stops rotating can suck pathogenic microorganisms in the patient's mouth back to the inside of the dental handpiece and enter the water and gas pipeline system of the comprehensive treatment table through the joint, causing pollution.
4. The opening of the down-hung pipeline is upward, which is easy to fall into foreign bodies, causing pipeline blockage or other failures. Therefore, it is necessary to empty the step before installing the handpiece to blow out the foreign matter that may fall into the pipeline to avoid causing failure.
●Proper use of dental handpieces
Before Use
1,Start the foot switch before installing the dental handpiece, spray the residual air and water in the tube, and observe whether the outlet water is normal.
2,Install handpiece, needle.
a. Lock needle type (screw type) : Install the handpiece on the treatment table, install the needle, use the dental handpiece key to gently tighten, must not be too hard, can be in place.
b. Button type (gland type) : press the button on the head of the handpiece, you can load and unload the needle, relax the button, the needle is clamped. After installing the needle, use your hand to test whether it is in place.
3, start the foot switch, the water is adjusted to the appropriate flow, the gas is adjusted to the appropriate pressure, high-speed handpiece standard pressure 0.2-0.23Mpa.
Note: It is strictly prohibited to step on the foot switch before the needle is loaded, otherwise the clamping mechanism will be easily damaged.
In Use
1, Dental handpiece in use, must be careful, meticulous, slight, strictly prohibited brutal operation, do not drop the handpiece to the ground.
2, No matter how the Angle, should follow the way of lifting up and down to operate, so that light touch, point, must not side force.
3, The use of improved pen holding handpiece, find a stable fulcrum, intermittent operation.
4, According to the different tooth position and the shape of the spare hole, timely replace the handpiece and the needle, as far as possible to reduce the wear of the handpiece bearing.
5,To use sharp needles, blunt needles not only time-consuming, laborious, but also cause damage to the handpiece, but also increase the pain of patients.
6,In the process of using the handpiece, it is necessary to often check whether the car needle is loose, so as not to cause flying needles.
7,Choose different handpieces according to different clinical conditions (such as the use of mini handpieces that do not affect the line of sight; The use of powerful high-torque handpieces in dental preparation).
8,The one-time workload is too large, two dental handpieces should be used in turn, one to avoid excessive damage to the handpiece load, and two to save the time to replace the handpiece.
9,The handpiece movement is serious radial swing, longitudinal movement is strictly prohibited to use, in the state of no water or water shortage is strictly prohibited to use the handpiece.
10,The air pressure and water pressure will change with the use of the treatment table, so the air pressure and water pressure should be checked frequently during clinical operation to ensure the normal use of the handpiece.
●Cleaning and maintenance of dental handpiece after use
1:Pretreatment
After the dental handpiece is used, it should be cleaned as soon as possible, otherwise the dirt will solidify and be difficult to clean. Before removing the needle, step on the foot brake to flush the tube cavity for 30 seconds, clean the debris on the working head with water mist, and remove the contaminated dental handpiece in time, and wipe the visible dirt on the surface of the dental handpiece with wet cotton balls in time.
2:Take down the needle
After use, only need to loosen the key (turn) 1/4 turn when going to the needle, too much loose, the three-lobe spring will be damaged to the back cover. After each use, the needle should be removed in time to facilitate the recovery of the mechanical parts of the handpiece needle.
3:Clean
●Ultrasonic cleaning machine is not recommended for dental handpiece cleaning, but automatic dental handpiece cleaning machine is recommended.
●If cleaning by hand, high-pressure water gun and air gun should be used in the tube cavity to flush the internal pipeline. Because of the variable speed, the internal contains two bearings, it is more difficult to clean, and the ideal state is the best manual cleaning + automatic cleaning machine.
●Cleaning water should be distilled or purified water.
4:Disinfect
The automatic cleaning machine has the effect of thermal disinfection. Manual cleaning should be carried out in accordance with the requirements of the "Hospital Disinfection Supply Center Part 2: Technical Operation Specifications for Cleaning, Disinfection and Sterilization".
5:Dry
Use a high-pressure air gun or syringe to dry the surface water of the pipe and wind wheel bearing, or inject 75% ethanol to dry. Natural drying methods should not be used for drying.
6:Check and Maintenance
●Check the cleanliness and performance of dental handpieces and instruments after drying with visual inspection or a magnifying glass with light source.
●Use automatic oiling equipment or hand to inject special handpiece cleaning lubricant into the inside of the dental handpiece.
7: Packing
Paper and plastic packaging should be used and sealed with a medical heat sealing machine. Other packaging and packaging processes shall be carried out in accordance with the operating procedures for packaging reusable surgical instruments.
8: Sterilization
Preferred pre-vacuum pressure steam sterilizer for sterilization, loading can not be stacked, leave a certain gap between the dental handpiece, paper face up, conducive to steam penetration and drying.
9:Storage
Bare sterilized should be stored in a sterile container, valid for no more than 4 hours. When using disposable paper and plastic packaging, the validity period should be 6 months.
●Dental handpiece maintenance equipment - Handpiece Lubricator
Dental oiler is a maintenance equipment, used for dental handpiece oil injection cleaning. Its role is mainly to lubricate and cool the dental handpiece, and remove the dirt and bacteria inside the handpiece. The high-tech design of the dental oiler enables it to provide a stable and continuous flow of lubricating oil, ensuring the normal operation of the mechanical equipment. The oiler plays an important role in prolonging the service life of the stomatology cell handpiece and preventing cross infection.
The working principle of the dental oiler is to send lubricating oil into various parts of the mechanical equipment through compressed air, so as to achieve the purpose of lubrication. Dental oiling machine is mainly composed of oiling machine body, sprayer, infusion tube and regulating system. Among them, the body of the oil filler is the core part of the whole equipment, which is mainly composed of the air source part, the controller, the atomizer, the liquid storage tank and the output system.
The working flow of the dental oiler is as follows:
First, add lubricating oil to the oil tank and connect the oil tank to the compressor. Then, the compressor is started and the compressed air feeds the lubricating oil into the tank. Then, start the oil pump and send the lubricating oil in the oil tank into various parts of the mechanical equipment. Finally, the lubricating oil is sprayed to various parts of the mechanical equipment through the oil nozzle to complete the lubrication process.
The role of the oil injection machine is mainly to help clean and cool.
In some oiler systems, the air work of the oiler can help with cleaning and cooling. When the oiler is running, some impurities and pollutants may accumulate in the pipeline and parts of the oiler, affecting the normal operation and lubrication effect of the oiler. By opening the blowing function, these impurities and pollutants can be effectively removed, and the oil injection machine can be kept clean and normal operation.
In addition, blowing can also help cool the oiler. When the oiler is running, some parts and lubricating oil may produce higher temperatures, which may affect the normal operation and life of the oiler. By opening the blowing function, the temperature of these parts can be effectively reduced, the normal operation of the oiler can be maintained and its service life can be extended.
