980nm and 2100nm holmium laser dual wavelength therapeutic instrument

Abstract

The invention discloses a 980nm and 2100nm holmium laser dual wavelength therapeutic instrument. The laser's optical path whose outputted wavelength is 532nm is provided in sequence with a first 45-degree angled reflection mirror (M1), a non-spherical lens (M4) and an optical fiber. The focal length of the non-spherical lens (M4) ranges from 15-25nm; and the two faces of the non-spherical lens (M4) are plated with 532nm, 980nm and 2100nm reflection reducing films. The laser's optical path whose outputted wavelength is 980nm is provided in sequence with a second 45-degree angled reflection mirror (M2), a first 45-degree angled reflection mirror (M1), a non-spherical lens (M4) and an optical fiber. The holmium laser's optical path whose outputted wavelength is 2100nm is provided in sequence with a third 45-degree angled reflection mirror (M3), a second 45-degree angled reflection mirror (M2), a first 45-degree angled reflection mirror (M1), a non-spherical lens (M4) and an optical fiber. The application scope of the holmium laser dual wavelength therapeutic instrument is further extended. Characterized by a simple structure and the advantage for convenient installation, the therapeutic instrument is capable of coaxially outputting through a single optical fiber three light-containing lasers. The instrument is also able to pulverize and cure diseased tissues of a person precisely.

Description

technical field [0001] The invention relates to a laser, in particular to a 980nm and 2100nm holmium laser dual-wavelength therapeutic instrument. Background technique [0002] At present, lasers invented by humans in the 20th century have been widely used in various fields of production and life. As applications in the medical field, lasers have been used to treat brain diseases, cardiovascular diseases, diabetes, malignant tumors, leukemia, psychiatry, etc. disease, psoriasis, rhinitis and other diseases. In order to give full play to the medical effect of laser, people have made various efforts, such as a holmium laser therapeutic apparatus published on November 23, 2016 in Chinese invention patent application CN 106137388 A. The therapeutic instrument is mainly composed of a holmium laser, an optical fiber and a detection treatment device connected in sequence, a control device connected to the detection treatment device, and an endoscope placed at the end of the optica...

AI Technical Summary

Problems solved by technology

Although this holmium laser therapy instrument can be used for crushing stones in the human body and cutting and vaporizing various tissues, it also has shortcomings. First, the single output wavelength limits the range of treatment and limits the treatment area. Secondly, the holmium laser with a wavelength of 2100nm is a mid-infrared light that is invisible to the human eye. During the treatment process, it is difficult for medical staff to precisely aim it at the affected area, which can easily damage the normal tissues of the human body and cause medical accidents.
