Abstract
The invention discloses a side-lit optical fiber for photodynamic therapy of prostatic diseases, comprising a fiber body. One end of the fiber body is connected with a fiber connector, while the other end is a laser output end. The side-lit optical fiber is characterized in that a fiber end at the laser output end is a slant, this slant end is disposed inside a transparent glass protective cover, the laser output end is fixed to a transparent casing through the protective cover, and the casing is provided with two mark points. The slant and the axis of the fiber make an included angle 25-28 DEG C. The two mark points are an emergence indicative mark point and a backlight indicative mark point, wherein the emergence indicative mark point is disposed below the slant and is consistent with an emergence direction, and the backlight indicative mark point is disposed opposite to the emergence indicative mark point. Light from the side-lit optical fiber is condensing and free of divergence and can irradiate accurately to a focal position in narrow space, and the side-lit optical fiber is convenient to adjust and use.
Description
Technical field
The present invention relates to medical laser light power optical fibers, specifically a kind of side light-coming out optical fiber for optical dynamic therapy prostatosis.
Background technology
Existing medical laser light power optical fibers, be generally point-like optical fiber and column optical fiber, the structure of these optical fiber comprises optical fiber body, and one end of optical fiber body is connected with the joints of optical fibre, and the other end is laser output.Before the treatment during row gland disease, because space in sick body tissue is very narrow and small, when the laser of point-like optical fiber is parallel to shaft axis of optic fibre injection from optic fibre end, cannot adjusts and make laser be radiated in focus; Although the laser of column optical fiber disperses injection around cylinder, this laser scattered out is dispersed, and does not condense, and the laser power after dispersing is less, and photosensitive drug can not be made to produce effect, and can be irradiated to non-lesions position, normal tissue produces infringement.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and a kind of side light-coming out optical fiber for optical dynamic therapy prostatosis is provided, this side light-coming out optical fiber goes out photocoagulator and does not disperse, and accurately can be irradiated to lesions position in small space, easy to adjust, easy to use.
The technical scheme realizing the object of the invention is:
A kind of side light-coming out optical fiber for optical dynamic therapy prostatosis; comprise optical fiber body; one end of described optical fiber body is connected with the joints of optical fibre; the other end is laser output; unlike the prior art, the optic fibre end of described laser output is inclined-plane, and this termination, inclined-plane is arranged in a clear glass protective cover; described laser output and protective cover are fixed by transparent casing, and sleeve pipe is provided with gauge point.
Described inclined-plane and the angle of shaft axis of optic fibre are 25-28 °.
Described gauge point is two, and be respectively bright dipping cue mark point and backlight cue mark point, wherein bright dipping cue mark point is arranged on the below on described inclined-plane, consistent with light direction, and backlight cue mark point is arranged in the opposite direction of bright dipping cue mark point.
Described bright dipping cue mark point is blue isosceles triangle gauge point, and the drift angle of described isosceles triangle faces described inclined-plane.
Described backlight cue mark point is red circular markers.
Also comprise the handle adjusting light direction, described optical fiber body is through the axis of handle, and handle is fixedly connected with optical fiber body.
Described handle is provided with arrow shaped groove or projection.
Dish out an inclined-plane in the termination of silica fibre by the present invention, change the direction of propagation of light, laser emits from optical fiber side, only irradiates for focus, do not injure normal tissue in narrow space; Termination, inclined-plane is arranged in glass tubing, and glass tubing and silica fibre are fixed by sleeve pipe, prevents glass tubing from coming off, and prevents the wedge angle of termination, inclined-plane from inserting tissue; Two visual marking points, observe the position of optic fibre end arrival with handled easily person, the exit positions of convenient adjustment optical fiber.
