• Description :
• Our Laser Instrument for Oral Cavity, which is specially based on oral cavity characteristics, is a novel medical instrument. It can treat pure gingivitis; Flatness lichen in oral cavity, periodontitis, pulpits, pericoronitis, dental caries and diseases of oral mucosa, and the curative effect is wonderful beyond all others. Therefore the application of the instrument is an effective means for diseases in oral cavity. As early as in the 1980s a medical Nd: YAG laser was applied to the oral cavity in USA and the Great Britain. The machine has many characteristics, such as small volume, light weight, easy operation, stable and reliable performance, fastness therapy, slight heat damage, short period of ulcer healing, no pain, no complications and a wonderful curative effect, so it is popular with clinic surgeons and patients. Compared with the product made in foreign countries, the instrument is not only of good quality, but also of low price. The price is ten times as low as that made abroad, which is about a hundred thousand US dollars per set. Structural Characteristics The machine is a fine instrument, which is integrated in optics, mechanics and electricity. Optical Path: As the 1064nm laser, which is emitted by the laser, is an invisible pulsed light, so an indicating and collimating beam must be needed. In order to minimize the volume, we use a He-Ne laser, which emits a red light of 633nm, as an indicating and collimating beam coaxially output with the Nd: YAG laser. The working media of the master laser is a high-quality Nd: YAG rod, and the machine is pumped by a high repetition-rate lamp. A Φ0.9mm optical fiber made of quartz is used for the laser delivery system, the output end of which can reach and is inserted into any part of patient´ S oral cavity. Power Supply A compact switching power supply is adopted, which has output of less than 500W, working at the repetition rate of 1Hz, 5Hz, 10Hz. The mains voltage used by the machine is AC 220V, 50Hz. Mechanics The metal case of the instrument is used, which is of small volume and durable. A reliable optical bench is adopted in need of high stability of the machine. The supporting optics board is a plate made of reinforced cast aluminum, which is hard to distort. A stainless steel tank and a magnetic pump are used in the recycling system of cooling water, where a recycling passage is connected by means of a hard pipe, so the blocking of the water path can be avoided.
