摘要

The high-speed turbine dental handpiece adapted for single safe use comprises a nose, a handle connected to the rear end of the nose, a plug connector disposed at the rear end of the handle, and a clip ring for fixing the handle and the plug connector, wherein the plug connector is provided with a first fixing slot at a side wall, the tail end of the handle is provided with a second fixing slot matched with the first fixing slot, the inner wall of the clip ring is provided with bumps matched with the first fixing slot and the second fixing slot, and when the clip ring is hooped on the plug connector, the bumps are embedded into the first fixing slot and the second fixing slot to limit and fix the handle and the plug connector. The invention effectively prevents the disposable dental handpiece from being reused in various ways, it is simple in structure and convenient to detach and thus can be conveniently detached and destroyed after being used, and in addition, with the disposable light-emitting component, whether the dental handpiece is used can be identified simply and clearly. According to the inventor, the concept of “one handpiece for one patient for single use” as advocated by the WHO in the field of oral health can be achieved, effectively solving the problem of iatrogenic cross infection in the field of stomatology. The invention is similar to a disposable syringe but with a more complex structure as a dental handpiece.
