Abstract

The non-sterile pneumatic turbine head includes a head assembly, the air turbine assembly includes a turbine, and bearings arranged at the upper and lower ends of the turbine. Holes and air outlet holes, slots are provided in the connecting part, the handle assembly is provided with a convex part inserted into the slot of the head assembly, and an air inlet channel and an air outlet channel that are connected with the air inlet hole and the air outlet hole are run through the convex part. It includes a flexible anti-return pad. The anti-return pad is arranged between the convex part and the bottom surface of the slot of the head assembly. The anti-return pad includes a base body. The base body is provided with an air intake resistance block and an air outlet resistance block. The area is larger than the air inlet channel and smaller than the air inlet hole. The air outlet channel of the convex part is provided with a gap, and the air outlet resistance block flexibly bends to the gap when it is impacted by the outflow gas, so that the air outlet hole and the air outlet channel are connected. The invention realizes partial replacement of the pneumatic turbine handpiece and avoids iatrogenic infection at the handle.

Description

technical field [0001] The invention relates to a handpiece of a disposable pneumatic turbine handpiece. Background technique [0002] The repeated use of the pneumatic turbine handpiece will cause hospital-acquired infection to patients, which is very unsafe and hygienic. Disposable pneumatic turbine handpieces currently on the market are directly replaced by a whole set of handpieces, which is costly and wastes resources. During the use of the pneumatic turbine handpiece, there are two parts of the infected part, the machine head and the handle. At present, there is no air turbine handpiece that can directly replace the handpiece to avoid iatrogenic infection. Contents of the invention [0003] In order to overcome the disadvantages of high use cost and waste of resources of the prior art disposable pneumatic turbine handpiece, the present invention provides a disposable non-sterilized pneumatic turbine handpiece. [0004] The technical solution of the present inventio...
