Abstract

A disposable high-speed turbine dental drill handpiece, the body of the machine head, the front handle and the rear handle have corresponding air hole channels, water mist air hole channels and central water hole channels, the air hole channels in the front machine handle, the center The water hole channel and the water mist air hole channel are respectively connected with an air hose, a water mist hose, and a water hose; It is connected with the barb joint of the trachea of ​​the machine head body, and the outside of the above-mentioned connection is tightly connected by a pipe hoop; the rear end of the water mist gas hose is connected with the barb joint of the water mist gas pipe of the rear machine handle, and the front end of the water mist gas hose is connected with the machine head body The water mist air pipe barb joint is connected, and the outside of the above connection is tightly connected by a pipe hoop; the rear end of the water delivery hose is connected to the water pipe barb joint of the rear machine handle, and the front end of the water delivery hose is connected to the water pipe barb joint of the machine head body Connection, the outside of the above-mentioned connection is tightly connected by a pipe hoop. The invention simplifies the installation process.

Description

(1) Technical field [0001] The invention belongs to a dental medical instrument, in particular to a hand-held appliance for drilling and grinding teeth. (2) Background technology [0002] The high-speed turbo dental drill handpiece is an essential hand-held device for drilling and grinding teeth in oral medicine, referred to as the handpiece. In order to prevent the cross-infection of diseases, the hospital has widely adopted the method of one person, one mobile phone, and one use, one disinfection. Disposable turbine dental drill mobile phones have also appeared. The existing disposable mobile phones are connected with metal air pipes and metal water pipes. This kind of structure is more complex, the assembly process is more troublesome, it needs to be welded, and the O-shaped rubber sealing ring is needed to seal the air and water, which not only increases the processing cost of the mobile phone, but also is difficult to control the production quality in mass production, a...
