Abstract

The utility model relates to a laser instrument external-cavity optical fiber medical treatment knife head, in particular to an modification of a fine optical fiber medical knife head with a glass matrix, which comprises an optical fiber seat, an axial adjustment nut, an axial movement speculum seat, an iris screw cap, a double convex lens, a lens seat, a lens, optical fiber, a screw cap, a fastening nut, a handhold handle, a fastening screw, a spreader spring, and a guidance key screw. An iris and a set of double convex lens are added in the utility model to adjust the position among the optical fiber on the optical fiber seat and the double convex lens and the iris screw cap, as well as the position relationship between the lens and the double convex lens, to meet the conditions of the high quality laser facula and energy uniformity output, for manufacturing the laser instrument external-cavity optical fiber medical knife head, and the adjustment of the medical knife head is convenient. The utility model has the advantages that the operation is simple, the cost is inexpensive, thus can be widely used for laser instruments and various medical laser instruments.

Description

A kind of laser device chamber infrared optical fiber treatment cutter head

Technical field

This utility model belongs to laser technology field, relates to laser device chamber infrared optical fiber treatment cutter head; Especially relate to a kind of improvement of treatment cutter head of thin optic fibre of glass basis.

Background technology

Optical fiber treatment cutter head outside the known laser instrument chamber is:

1) directly the optical fiber on the laser cavity inner fiber coupling positioner is derived, add upper handle or add a diaphragm promptly available at outfan.

2) being 1) in the basic Chu, optical fiber output front end is installed a slice lens on handle, and the laser facula of optical fiber output is converged.

But answering proving effect by practice is not clearly, and the optical quality of laser power output is undesirable; The Energy distribution inequality has a strong impact on therapeutic effect.

Summary of the invention

In order to solve the Energy distribution inequality of laser power output, the problem of optical quality difference, this utility model provides a kind of laser device chamber infrared optical fiber treatment cutter head, improves therapeutic effect.

Detailed content of the present utility model: this treatment cutter head comprises fiber bench, axial adjustment nut, moves axially microscope base, aperture and nut, biconvex lens, lens mount, lens, optical fiber, nut, locking nut, hand holding handle, lock-screw, stage clip, feather key screw.

Its static structure and mutual relation characteristics are: at first optical fiber is installed on the fiber bench, biconvex lens is installed to moves axially on the microscope base then, and tighten up with aperture and nut.Afterwards stage clip is put into and moves axially in the microscope base pilot hole, again fiber bench is packed into along the feather key orientation, feather key screw and axial adjustment nut are installed then; And will together be installed on the hand holding handle, use lock-screw fastening afterwards.Then lens are installed on the lens mount, and with together being contained on the hand holding handle with locking nut after the nut compressing.

Outstanding feature of the present utility model is; Increase an aperture and one group of biconvex lens, thereby constituted a kind of new optical system.Regulate optical fiber and biconvex lens on the fiber bench; Position between the aperture nut; And the relation of the position between lens and the biconvex lens, satisfy the condition that obtains high-quality laser facula and energy even output.Thereby provide a kind of new equipment of laser device chamber infrared optical fiber treatment cutter head.

The utility model has the advantages that; Can the good laser facula of stabilized uniform output quality with this laser device chamber infrared optical fiber treatment cutter head, improve the quality of optical fiber treatment cutter head, improve therapeutic effect.This laser device chamber infrared optical fiber treatment cutter head is easy to adjust, simple to operate, stable performance.Can be widely used in laser device and the various medical laser instrument.

Description of drawings:

Fig. 1 is a section of structure of the present utility model

Fig. 2 is a left pseudosection of the present utility model

Parts are among the figure: fiber bench 1, axial adjustment nut 2, move axially microscope base 3, diaphragm nut 4, biconvex lens 5, lens mount 6, lens 7, optical fiber 8, nut 9, locking nut 10, hand holding handle 11, lock-screw 12, stage clip 13, feather key screw 14.

The specific embodiment

Embodiment of the present utility model: according to battery of lens optical quality is had grooming function, at first with part fiber bench 1; Axial adjustment nut 2; Move axially microscope base 3; Diaphragm nut 4; Biconvex lens 5; Optical fiber 8; Stage clip 13; 14 assemblings of feather key screw together.Again with lens mount 6; Lens 7; Nut 9; Locking nut 10; Lock-screw 12 assemblings together.Together be installed on the hand holding handle 11 afterwards.When this moment, if endovenous laser was by the existing output of optical fiber, for making the output of laser device chamber infrared optical fiber treatment cutter head laser best, after at first unclamping the feather key screw 14 that moves axially on the microscope base 3 during debugging, regulating shaft is locked feather key screw 14 after adjusting nut 2 makes the relative biconvex lens 5 position the bests of optical fiber; Locking nut 10 is unclamped, relay lens seat 6 is regulated lens 7 and is made its best with biconvex lens 5 positions again, thereby obtains the output of high-quality laser facula and energy even, afterwards again with locking nut 10 lockings.To guarantee this device stability; Can both guarantee laser stabilization output during each the use.Biconvex lens 5 adopts K9 optical glass to make with lens 7; Fiber bench 1; Axial adjustment nut 2; And move axially microscope base 3 diaphragm nuts 4 and lens mount 6; Nut 9; Locking nut 10; Hand holding handle 11 all uses aluminium alloy (2Al2) to make.Optical fiber 8 and lock-screw 12 (standard component) outsourcing; Stage clip 13 usefulness carbon element carbon spring steel wires are made.No. 45 steels of feather key screw 14 usefulness are done.
