Embodiment Construction

[0025] see figure 2 , Figure 4 , The front end of rear machine handle 4 establishes air inlet duct 42 and water inlet duct 41. Air pipe 5 and water pipe 6 from machine head 1 are inserted into air inlet tunnel 42 and water inlet tunnel 41 . Their connecting gaps are sealed with air pipe sealing O type ring 16 and water pipe sealing O type ring 17 respectively. Water inlet channel 41 is also provided with waterproof back-suction one-way valve 14, and the quick-insert inner tube 45 at the tail of the rear handle can be designed into various structures of different sizes, which can be plugged with various quick-inserted gas from dental treatment machines. Water connector 13.

[0026] One end of the rear handle is plugged with the front handle 3 of the mobile phone, and the other end is connected with the quick-plug air-water connector 13 from the dental treatment machine. When connecting, the quick-insert air-water joint sheath 12 needs to be pulled backwards so that the th...

Abstract

The disposable high speed turbine dental drill hand piece has one handle made of molded engineering plastic, and the handle has one integrated back part for connection to the dental drill hand piece and the other end made into tail structure suitable for connecting with water pipe and air pipe easily. The handle features its front part in inserting structure with O-ring for sealing the air pipe and water pipe union. The back part of the handle may be in different sizes for fast connection to water pipe and air pipe of different sizes. The handle may have one non-return valve installed to avoid back flow of water. The handle has light weight, high strength, easy manufacture and installation and low cost and is suitable for use in disposable high speed turbine dental drill hand piece.

Description

Technical field: [0001] The invention belongs to a dental medical instrument, in particular to a hand-held appliance for drilling and grinding teeth. Background technique: [0002] The high-speed vortex drill handpiece is a device used by doctors to drill and grind teeth. It uses clean compressed air as the power source, blows the turbine to rotate at a speed of about 300,000 revolutions per minute, and drives the cutting tool (dental needle) to drill and grind teeth. When a doctor uses a high-speed turbo dental drill handpiece for treatment, it will inevitably come into contact with the patient's teeth, oral mucosa, teeth and blood. If the doctor shares a dental drill handpiece with all patients during the treatment, incomplete disinfection and sterilization will lead to the spread of certain diseases, especially diseases such as AIDS, hepatitis, etc. that are transmitted through blood, saliva and mucous membranes. It is particularly worth noting that: since the high-speed...
