Described optically focused cavity adopts the structure of laser pump (ing) laser pump cavity, is the single elliptical shape of total reflection, is two copolymerization Jiao's oval cavity, is made of the oval cavity of the two parts that are connected through the hinge.
Described strong ultraviolet source is that the low pressure pulse xenon long-arc lamp by two surface coatings is installed on respectively on intravital two the non-public focal axis of oval laser pump cavity by support, and is formed by connecting with the high-voltage switch power supply that adopts the high frequency pumping mode.
The water route of described dental drill, gas circuit are equipped with photocatalyst compound sterilizing liquid spout, are equipped with the waste liquid returnable at the spout place.
When dental drill is sterilized, open laser pump cavity, dental drill is positioned on the public focal axis of two oval cavitys, in bactericidal liquid ejection spout, strong ultraviolet light produces photochemical reaction by waveguiding effect and photocatalyst compound sterilizing liquid, thereby reach the sterilization to the dental drill inner chamber, the waste liquid that the dental drill spout ejects is recycled to the waste liquid returnable by the mouth of pipe of laser pump cavity bottom with the waste liquid after the sterilization.
Compared with prior art, the invention has the beneficial effects as follows: in non-clinical biochemical test, with hepatitis B pathogenic bacteria and black withered tooth spore bacterium is main test strain, under non-water bath condition, carry out the sterilization of 30 seconds and 60 seconds, sterilization finishes back dental drill surface temperature rise all less than 20 ℃, and hands tool internal structure wears out, dissolves much smaller than making in absolute temperature rise, the temperature threshold values of modification, degraded.Hands tool after sterilization cleans with cleaning culture fluid, cleanout fluid is found after cultivating in 24 hours, this sterilizing installation can be killed hepatitis B pathogenic bacteria and 95% above black withered tooth spore bacterium in 30 seconds fully, and sterilization time reaches on the dental drill after 60 seconds bacterial strain to be killed fully, does not have germ carrying in the culture medium.This shows that the present invention has avoided the high temperature ageing problem of the pneumatic and waterway member of high speed turbine dental drill, the problem that " resorption " that has caused when having avoided the high speed turbine dental drill stall simultaneously carries disease germs and be difficult to go out and remove.
