Medical sealed-off carbon dioxide laser tube

Abstract

The invention discloses a medical sealed-off carbon dioxide laser tube which comprises a discharge tube, a water-cooled tube, a gas storage tube, a gas return tube, a total reflector, an anode electrode, an output reflector and a cathode electrode, a nanometer gold coating which plays a catalytic role and a voltage reducing and current stabilizing role is arranged on the inner wall of the discharge tube through a chemical plating technology, and the length of the discharge tube ranges from 0.6 m to 0.95 m. The medical sealed-off carbon dioxide laser tube is suitable for medical use, the power is smaller, the volume is smaller, by means of the nanometer gold coating, the catalytic role of carbonic oxide molecules and oxygen atoms are accelerated, and the service life is prolonged. In addition, the nanometer gold coating further has the voltage reducing and current stabilizing role, the electrostatic voltage of the laser tube can be decreased to range from 160 V to 220 V, the current can be reduced, therefore, working of the laser tube can be more stable, the quality of facula emitted by a laser is guaranteed, and the medical facula requirements are met.

Description

technical field [0001] The invention relates to the field of carbon dioxide laser tubes, in particular to a medical sealed-off carbon dioxide laser tube. Background technique [0002] The tube body of the current sealed-off carbon dioxide laser tube is composed of a discharge tube, a water-cooled tube, a gas storage tube and a gas return tube by firing extra-hard glass frit, usually with a three-layer casing structure. The innermost is the discharge tube, the middle is the water cooling tube, the outermost layer is the gas storage tube, and the gas return tube is used to connect the discharge tube and the gas storage tube. A total reflection mirror is arranged on the nozzle at one end of the gas return pipe, and an anode electrode is arranged at the discharge tube at this end; an output reflection mirror is arranged at the nozzle at the other end, and a cathode electrode is arranged at the discharge tube at this end. [0003] During the use of the current carbon dioxide las...

AI Technical Summary

Problems solved by technology

Also, the coating is slower to catalyze carbon monoxide molecules and oxygen atoms, resulting in a shorter service life

[0006] In addition, the above-mentioned patent also has the situation that the discharge tube is easily bent due to heat generation, gravity, etc., which affects the quality of the laser spot

[0007] Furthermore, the static voltage of a general carbon dioxide laser tube is between 185-220V, and the current is too large, which makes the laser tube work unstable.
