Problems solved by technology

Semiconductor laser tubes are very sensitive to temperature and can easily cause thermal damage
According to the environmental requirements of medical electrical equipment, the semiconductor laser treatment instrument must select a climate and environment group, that is, the semiconductor laser treatment instrument must meet a specified operating temperature range, and the laser power generated by the semiconductor laser tube is very sensitive to temperature changes. It can be seen from the curve that as the working temperature rises, the laser power will drop rapidly. However, as a medical laser, in order to ensure the clinical effect of laser treatment, it is necessary to ensure the accuracy of the irradiation dose of laser treatment, and it is necessary to increase the work rate through the feedback control circuit. Current, keep the laser power relatively stable, which makes the semiconductor laser tube emit the same laser power, the higher the operating temperature, the greater the operating current, and the greater the heat generated by the laser tube. Inadequate selection of the model or improper design of the heat dissipation structure of the treatment head will cause ablation damage to the laser tube
[0004] Second, it is easy to be damaged by static electricity
[0006] At the same time, the existing technology still lacks a technical solution for safety protection in laser irradiation, such as patent No. 97222500.5, which does not mention the safety technical guarantee of the treatment head of the semiconductor laser therapeutic instrument in clinical application in the technical solution and structural design The content of the plan lacks the safety design guarantee of the treatment head for laser emission in clinical treatment

Abstract

The invention relates to a nasal cavity irradiating therapeutic head of a semiconductor laser therapeutic apparatus, which can reach effectiveness and safety requirements on laser clinical therapies. The nasal cavity irradiating therapeutic head comprises a laser, a heat-stabilized heat conducting device, a packing positioning device, a light guiding and transmitting device, a laser window cover, a housing, a nasal clip device and a power supply lead, wherein the heat-stabilized heat conducting device is designed according to heat balance temperature to control the operating temperature range of the laser, the light guiding and transmitting device is designed according to fiber optical light guide transmission so that the laser is far away from a laser irradiating window, which is beneficial to structural design; meanwhile, a fiber numerical aperture is used for ensuring the guide and the scattering output of scattered semiconductor laser. The housing is made from an insulating material and is an anti-static electromagnetic compatibility design, which prevents electrostatic interference from causing the laser power attenuation and the laser damage. The laser window cover is designed by adopting safe irradiation power density of a light outputting opening and laser scattering irradiation on light spots, the safety control of laser irradiation is provided, and thus the effectiveness of the clinical therapies and the safety of the laser irradiation can be ensured.

Description

technical field [0001] The invention relates to a treatment head of a semiconductor laser treatment instrument. Background technique [0002] The semiconductor laser tube is the main functional device of the treatment head and the core component of the semiconductor laser therapeutic device. The structural characteristics of semiconductor laser tubes determine that it has two major weaknesses: [0003] One is heat damage. Semiconductor laser tubes are very sensitive to temperature and can easily cause thermal damage. According to the environmental requirements of medical electrical equipment, the semiconductor laser treatment instrument must select a climate and environment group, that is, the semiconductor laser treatment instrument must meet a specified operating temperature range, and the laser power generated by the semiconductor laser tube is very sensitive to temperature changes. It can be seen from the curve that as the working temperature rises, the laser power wi...
