When the water pump 38 is operated and the two-way solenoid valve 44 is opened, the compressed air or other safety gas passes through the gas pressure reducing valve 40, the two-way solenoid valve 44 and the gas flowmeter 22 in sequence, is mixed with the purified water 35 at the three-way joint 53, enters the hand tool d through the connecting pipe 10 and is sprayed out in a mist form from the water outlet of the hand tool d. After the set laser start delay time, the laser D emits laser, and reaches the hand tool D through the optical fiber 94 and then reaches the focus part of the oral cavity of the patient for treatment.

When the foot pedal is released, the system is halted, the water pump 38 stops, and the two- way solenoid valves 42, 44 are closed. And the condition of the focus part is observed again through a real-time picture on the touch display screen, when the foot switch is stepped down again, the system is started again, and the operation is circulated until the operation is finished.

If the patient carries out the tooth preparation treatment during the treatment, the original three-dimensional sizes of the tooth to be treated and the left and right teeth are scanned by the hand-held dental 3D scanner 8 in the treatment process, the three-dimensional model is displayed on the matched software on the touch display screen after the scanning is finished, the size and the shape of the tooth to be treated are observed and measured by the aid of the software, and then the hard tissue excision treatment is carried out. The dental 3D scanner 8 may be held by a hand during treatment to scan the three-dimensional dimensions of the treated tooth and the left and right teeth. And then comparing the sizes of the first model and the second model, and displaying the cut part of the hard tissue in different colors, so that whether the size and the shape of the cut part meet the requirements of tooth preparation can be observed, if the size and the shape of the cut part do not meet the requirements of cutting treatment again, the prosthesis design is carried out, and after the design is finished, the data are directly sent to a processing plant for 3D printing of the prosthesis.

After the operation is finished, the hand tool d is carefully taken down, the tools are picked up and then taken to the cleaning device together for cleaning in time, after the cleaning is finished, the hand tool d is placed into the vacuum drying device for drying, and then is placed into the sterilization and disinfection device 46 for sterilization and disinfection treatment. And finally, the illuminating lamp 6, the medical CCD camera 11 and the like are returned, the software on the touch display screen is turned off, and the system power supply is turned off.

It should be understood that the above embodiments are exemplary only, and are not intended to limit the present invention. Various modifications and alterations of the above-described embodiments may be made by those skilled in the art in light of the teachings of the present invention without departing from the scope thereof.
