Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a long-wavelength semiconductor laser medical device, in particular to a portable, high-power semiconductor laser therapeutic instrument for medical optical fiber transmission used in soft tissue cutting. Background technique [0002] In recent years, with the continuous development of laser technology, lasers of various wavelengths have been used more and more widely in the field of treatment of human soft tissue diseases, but they all have certain limitations during the treatment and fail to achieve the best results. [0003] We know that the near-infrared laser of 800nm-1064nm is mainly absorbed by melanin and oxyhemoglobin, which has good coagulation and hemostasis effects in clinical practice, but has poor vaporization cutting ability for tissues; 2.1μm holmium laser (Ho:YAG) It has a good soft tissue resection ability when working in a short pulse and high energy state, but it ...

[0002] In recent years, with the continuous development of laser technology, various wavelength lasers have become more and more widely used in the field of treatment of human soft tissue diseases, but they all have certain limitations during treatment and cannot achieve the best results

[0003] We know that the near-infrared laser of 800nm-1064nm is mainly absorbed by melanin and oxyhemoglobin, which has good coagulation and hemostasis effects in clinical practice, but has poor vaporization cutting ability for tissues; 2.1μm holmium laser (Ho:YAG) It has a good soft tissue resection ability when working in a short pulse and high energy state, but it is prone to split damage, easy to bleed, difficult to learn and master surgical skills, and the treatment instrument has a complex structure and large volume; green laser (KTP) It can effectively remove human soft tissue, and has the advantages of simple method, quick effect, and good hemostasis effect. However, the area of ​​missing tissue is large after operation, and the wound repair time is long, which increases the risk of secondary bleeding or secondary infection. Tissue coagulation reduces resection rate
