Abstract

A disposable high speed turbo dental drill handset is disclosed, wherein the interior of the frame head, the front bolt handle and the back bolt handle are equipped with the corresponding air hole channel, the water spray air hole channel and the central water pore channel, while the air hole channel, the central water pore channel and the water spray air hole channel in the front bolt handle are equipped with an air hose, a water fume hose, a water hose. The back end of the air hose is connected with the air tube barb joint of the back bolt handle, and the front end of the air hose is connected to the air tube barb joint of the frame head, wherein the outside of the joint is tightly connected by the pipe holder. The back end of the water fume hose is connected with the water spay trachea barb joint of the back bolt handle, and the front end of the water fume hose is connected with the water spay trachea barb joint of the frame head, wherein the outside of the joint is tightly connected by the pipe holder. The back end of the water hose is connected with the water pipe barb joint of the back bolt handle, and the front end of the water hose is connected with the water bard joint of the frame head, wherein the outside of the joint is tightly connected by the pipe holder. The invention simplifies the installation technology.

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...
