Description

Technical Field

[0001] This invention relates to the field of laser therapy technology, and in particular to a thulium-doped fiber laser therapy machine. Background Technology

[0002] Thulium-doped fiber laser therapy is a laser medical device that uses thulium-doped optical fiber as the laser medium. Currently, existing laser therapy devices all utilize only one of the two peaks (e.g., using a single wavelength of 1.72μm). However, human tissue contains about 80-90% water, so the laser must pass through the water-rich human tissue to reach the target tissue. Although water does not absorb 1.72μm wavelength laser as strongly as fat, it will still cause some of the laser to be lost when it reaches the sebum, thus failing to exert its maximum effect and reducing the therapeutic effect.

[0003] Therefore, it is necessary to provide a novel thulium-doped fiber laser therapy machine to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide a thulium-doped fiber laser therapy machine. The main control board of the device sends control commands to the laser control board, which then controls the thulium-doped fiber laser to operate. The thulium-doped fiber laser generates laser light (wavelength 1940nm) for the treatment of the patient's human tissue. Based on the thermal effect, it burns, coagulates, vaporizes diseased tissues in various parts of the human body to achieve the therapeutic purpose, and has a very good therapeutic effect.

[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows: a thulium-doped fiber laser therapy machine, comprising: a filter module, a solid-state relay, a first switching power supply, a second switching power supply, a constant current source, a laser control board, a main control board of the equipment, and a thulium-doped fiber laser;
