Compound-glass optical fiber bundle device

Abstract

The invention provides a compound-glass optical fiber bundle device which comprises a quartz-glass optical fiber, a multi-component glass optical fiber bundle, a connecting support, an operating handle and a positioner. An input end of the quartz-glass optical fiber and an input end of the multi-component glass optical fiber bundle are independent from each other, and the quartz-glass optical fiber and the multi-component glass optical fiber bundle are respectively mounted in two auxiliary metal hoses; the quartz-glass optical fiber and the multi-component glass optical fiber bundle which are separated from each other are gathered in a main metal hose by the connecting support; the operating handle is positioned at the end, which is far away from the connecting support, of the main metal hose, one end of the operating handle is connected with the main metal hose, and a compound optical fiber bundle head is arranged at the other end of the operating handle; the positioner is arranged at the other end of the operating handle and is externally disposed at a laser output end of the compound optical laser bundle head; and the quartz-glass optical fiber and the multi-component glass optical fiber bundle are compounded in the compound optical fiber bundle head, laser outputted by the quartz-glass optical fiber is used as an optical axis, the multi-component glass fiber bundle is closely arrayed on the periphery of the quartz-glass optical fiber in a concentric distribution mode, and the laser outputted by the quartz-glass optical fiber and laser outputted by the multi-component glass optical fiber bundle are intersected with each other at an output end of the positioner.

Description

technical field [0001] The invention belongs to the field of laser medicine, and more specifically relates to a composite glass fiber bundle device. Background technique [0002] At present, laser acupuncture treatment has been widely used in clinical treatment. The laser used for treatment is mainly He-Ne laser, and other single-wavelength lasers such as 650nm semiconductor laser. Lasers in these wavelength ranges can penetrate deep into human tissues and replace the needles in traditional acupuncture, so they are commonly called "laser needles". [0003] For example, the function and mechanism of "light acupuncture" published in "Shanghai Journal of Acupuncture and Moxibustion" (December 1999, Volume 18, Issue 6), published in "Applied Laser" (December 1999, Volume 19, Issue 6) The "Physical Basis of Laser Acupuncture" and other articles mentioned the mechanism of action of laser needles. In addition, a laser therapeutic instrument is disclosed in Patent Document 1 with ...

Problems solved by technology

However, since the laser spot output by the silver halide crystal fiber is elliptical, the energy distribution as laser moxibustion is uneven

In another composite optical head with a structure, the silver halide crystal fiber is used as the optical axis, and the quartz glass fiber is concentrically distributed around the silver halide crystal fiber in the form of a bundle. However, the composite optical head composed of this will make the laser needle The laser spot becomes larger, resulting in a decrease in laser energy density

Therefore, the clinical effect of the composite optical fiber device in practical applications has been affected to a certain extent.
