The first connecting section 101 is in threaded connection with the transfer conduit 206, the light guide 213 is wrapped outside the first connecting section 101, the whole structure is more compact, the volume is small, and dust and impurities are not easy to enter.
In order to ensure the sealing property, sealing members are arranged at the joint of the gas sand channel and the pipeline and the joint of the liquid channel and the pipeline.
In the sandblasting handle 002 provided in this embodiment, after the handle body 200 and the spray head are installed, the central axis of the handle body 200 coincides with the central axis of the first connecting section 101. That is, the handle body 200 forms an included angle of 90-150 degrees with the second nozzle segment 110, which is convenient for operation. During use, illumination is provided by illumination system 210, and the operator is more aware of the conditions within the cavity, improving the therapeutic effect. When the sand blasting handle 002 is blocked in the use process, the spray head and the handle body 200 can be detached, and the spray head can be detached into two parts, so that the dredging is convenient, and the replacement is also convenient.
Example 3
