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.

Embodiment 1

[0043] Such as Figure 1 to Figure 2 As shown, an optical fiber connector 1 is installed on the input end of the silica glass optical fiber 2 with a small numerical aperture, and the two ends of the secondary metal hose 31 are respectively connected with the optical fiber connector 1 and Y of the silica glass optical fiber 2 with a small numerical aperture by threaded connections. Shaped bracket 5 is connected. An optical fiber connector 6 is installed on the input end of the quartz glass optical fiber 7 with a large numerical aperture, and the two ends of the secondary metal hose 32 are respectively connected with the optical fiber connector 6 and the Y-shaped support 5 of the quartz glass optical fiber 7 with a large numerical aperture through threaded connections. connected. The quartz glass optical fiber 2 with a small numerical aperture and the quartz glass optical fiber 7 with a large numerical aperture are assembled in the Y-shaped bracket 5 and placed in the main meta...

Embodiment 2

[0045] In the composite optical fiber head 9 composed of the silica glass optical fiber 2 with a small numerical aperture and the silica glass optical fiber 7 with a large numerical aperture, the two optical fibers are parallel and close to each other. In Example 2, the numerical value of the silica glass optical fiber 2 with a small numerical aperture is The aperture is 0.2, the divergence angle α1=22°, and the diameter is φ0.2mm; the numerical aperture of the quartz glass fiber 7 with large numerical aperture is 0.36, the divergence angle α2=40°, and the diameter is φ0.4mm. According to the calculation, detection and clinical test, at the position L=18mm of the length of the positioner 10, the light spot output by the quartz glass fiber 7 will completely cover the light spot of the quartz glass fiber 2, realizing the compounding of the two lasers.

Embodiment 3

[0047] Although not shown in the figure, it is also possible to connect a 2×1 silica glass fiber coupler to the optical fiber connector 1 of the silica glass optical fiber 2 with a small numerical aperture in the composite silica glass optical fiber device of Example 2, so that the numerical aperture A small silica glass fiber 2 is extended with two inputs. Thus the composite silica glass optical fiber device of the present invention can be formed to have three input ports so that laser light of three different wavelengths can be transmitted.

Abstract

The invention provides a compound quartz glass optical fiber device which comprises two quartz glass optical fibers, a connecting support, an operating handle and a positioner. Input ends of the two quartz glass optical fibers are independent from each other, the two quartz glass optical fibers are respectively mounted in two auxiliary metal hoses, and apertures of the two quartz glass optical fibers are different from each other; the connecting support is used for gathering the two separated quartz glass optical fibers in a main metal hose; 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 fiber bundle head; and the two quartz glass optical fibers are compounded in the compound optical fiber bundle head, laser which is outputted by the quartz glass optical fiber with the small aperture is used as an optical axis, the quartz glass optical fiber with the large aperture is parallelly abutted to the quartz glass optical fiber with the small aperture, and the laser outputted by the optical fiber with the small aperture and laser outputted by the optical fiber with the large aperture 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 quartz glass optical fiber 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...
