Abstract
The utility model discloses a holmium laser generator, which comprises a cavity, holmium crystal bars, xenon lamps, total reflecting mirrors, a half reflecting mirror, a coupling mirror and an optical fiber, wherein two groups of holmium crystal bars and xenon lamps are arranged in the cavity in parallel, each group of holmium crystal bar and xenon lamp comprises one holmium crystal bar and one xenon lamp which are mutually parallel, the xenon lamps are arranged at the outsides of the holmium crystal bars, two ends of the xenon lamps are respectively connected with the output end of a laser power supply, one end of the cavity is provided with two total reflecting mirrors which are respectively vertical to optical axes of the two holmium crystal bars, the other end of the cavity is provided with the half reflecting mirror vertical to the optical axes of the two holmium crystal bars, and the coupling mirror and the optical fiber are arranged on one side far away from the cavity of the half reflecting mirror with the central axis from the near to the distant. The holmium laser generator is mainly used for a holmium laser medical machine, solves the problems of poor reliability or oversize size and too-high production cost of the existing holmium laser generator, and has the advantages of high reliability, small size and low production cost.
Description
Technical field
This utility model relates to a kind of holmium laser generator, belongs to laser or laser medical equipment technical field.
Background technology
Adopting the laser surgery treatment human body diseases is a much progress of contemporary medical science.At present, often adopt carbon dioxide laser medical treatment machine that pathological tissues is burnt, excises, in this process; Because it is comparatively serious to the carbonizing degree of pathological tissues; And bigger to the hot injury of the when injected organism tissue around the pathological tissues, so the healing of patient's post-surgical trauma is slower, convalescent period is longer.
Though bait laser is on the best absworption peak of water, because prior art can not use the optical fiber transmission wavelength to surpass the laser of 2.6 μ m, it can only transmit with light-conducting arm, has limited it and can only do some operations of body surface.
The holmium laser output wavelength is 2100nm, belongs to the middle infrared (Mid-IR) scope, and its wavelength is near the first absworption peak 1950nm (living organism contains moisture 70%-80%) of water; Therefore, holmium laser is very easily absorbed by biological tissue very soon, gives full play to its effect; Have fabulous burn, solidify, vaporization, cutting effect, be not only applicable to the body surface operation, and can with endoscope and various tool fit applications; Do intracavity, the operation of intracranial insertion type easily, realize Wicresoft's wound or atraumatic surgical.
The holmium laser generator of existing holmium laser therapeutical machine mainly contains two kinds of forms, and a kind of is single chamber single lamp list bar type, and another kind is the two lamp twin stem types of two-chamber.First kind of holmium laser generator is owing to have only one road generating device of laser, so when this road generating device of laser broke down, the holmium laser therapeutical machine will be ineffective, and this might delay doctor's hands art in operation process; Second kind of holmium laser generator is owing to there is the two-way generating device of laser, so the reliability of this holmium laser generator is higher, but it also exists volume excessive simultaneously, the problem that production cost is higher.
The utility model content
The purpose of this utility model provides a kind of holmium laser generator, has holmium laser generator or poor reliability now to solve, or the problem that volume is excessive, production cost is higher.
The purpose of this utility model realizes through following technical scheme:
A kind of holmium laser generator; Comprise cavity, holmium crystal bar, xenon lamp, total reflective mirror, half anti-mirror, coupling mirror and optical fiber; Be provided with two groups of holmium crystal bars and xenon lamp in the said cavity abreast; Every group of holmium crystal bar and xenon lamp comprise a holmium crystal bar and an xenon lamp that is parallel to each other; Said xenon lamp is positioned at the outside of said holmium crystal bar, and the two ends of said xenon lamp are connected with the outfan of Laser Power Devices respectively, an end of said cavity be provided with two respectively with the vertical total reflective mirror of two holmium crystal bar optical axises; The other end of said cavity is provided with one and the vertical half anti-mirror of two holmium crystal bar optical axises, and said coupling mirror and optical fiber from the close-by examples to those far off are arranged on said half side of anti-mirror axis away from cavity.
The beneficial effect of this utility model is: through adopting the version of the two lamp double sticks in single chamber, both guaranteed reliability, and effectively dwindled volume again, and reduced production cost.
Description of drawings
According to accompanying drawing and embodiment this utility model is done further explain below.
Fig. 1 is the structural representation of this utility model.
Among the figure: 1, cavity; 2, holmium crystal bar; 3, xenon lamp; 4, total reflective mirror; 5, half anti-mirror; 6, coupling mirror; 7, optical fiber.
The specific embodiment
As shown in Figure 1; The holmium laser generator of this utility model; Comprise cavity 1, holmium crystal bar 2, xenon lamp 3, total reflective mirror 4, partly anti-mirror 5, coupling mirror 6 and optical fiber 7; Be provided with two groups of holmium crystal bars 2 and xenon lamp 3 in the said cavity 1 abreast, every group of holmium crystal bar 2 comprises a holmium crystal bar 2 and an xenon lamp 3 that is parallel to each other with xenon lamp 3, and said xenon lamp 3 is positioned at the outside of said holmium crystal bar 2; The two ends of said xenon lamp 3 are connected with the outfan of Laser Power Devices respectively; One end of said cavity 1 be provided with two respectively with the vertical total reflective mirror 4 of two holmium crystal bars, 2 optical axises, the other end of said cavity 1 be provided with one with the vertical half anti-mirror 5 of two holmium crystal bars, 2 optical axises, said coupling mirror 6 from the close-by examples to those far off is arranged on said half side of anti-mirror 5 axis away from cavity 1 with optical fiber 7.
The work process of this utility model is: connect Laser Power Devices, Laser Power Devices export xenon lamp to, after xenon lamp is lighted; The fluorescence that produces gathers on the holmium crystal bar through laser pump cavity, forms population inversion, produces excited radiation light; And between total reflective mirror and half-reflecting mirror, come and go the vibration amplification, when gain is enough, from half anti-mirror output; Gather on the optical fiber through coupling mirror, import organism by optical fiber pathological tissues is burnt, solidifies, gasifies, cuts.
This utility model is mainly used in the holmium laser therapeutical machine, has solved existing holmium laser generator or poor reliability, or the problem that volume is excessive, production cost is higher, has reliability height, volume is little and production cost is low advantage.
