Abstract
The utility model relates to a hard cold-light illuminator of an endoscope. The resolving performance and the brightness of the illumination are enhanced by using the cold-light illumination to replace the incandescent illumination in the prior art. The utility model mainly comprises a single light conducting fiber 2 of which both ends are respectively made into a sphere 1 and a cone 6, a protection layer 3 of the light conducting fiber, a joint 4 which is provided with a flange, and a spherical surface convex lens 7 which is installed at the joint. The hard cold-light illuminator of an endoscope can be matched with various cold-light sources. The hard cold-light illuminator of an endoscope is used for the illumination of the hard oesophagoscope, the bronchoscope, etc. The utility model has the advantages of simple structure and convenient operation.
Description
Hard endoscope cold light illumination unit is supporting with the cold light light source, is exclusively used in the illuminator in the hard endoscope, belongs to medical mechanical domain.
In the prior art, the used illuminator of hard endoscope is a low-voltage, the weak current electric filament lamp, because electric filament lamp brightness is low, light quality is poor, so the resolving power of this device is low, influence is bigger when being particularly useful for the tissues observed pathological changes.
The purpose of this utility model is: provide cold light illumination unit that a kind of suitable hard endoscope uses to improve illumination light brightness, improve light quality, strengthen resolving power.
Figure of description is a structural representation of the present utility model.1 is spheroid among the figure, the 2nd, and optical fibers, the 3rd, protective layer, the 4th, joint, the 5th, flange, the 6th, cone, the 7th, sphere convex lens.
In the utility model, optical fiber 2 is single, and an end (entering the human body end with rigid endoscope) of optical fiber 2 is made spheroid 1, and its purpose is to make the light diffusion, forms an area of illumination (avoiding forming local hot spot) at institute's look-out station. The other end (cold light source acceptance end) of optical fiber 2 is made a cone 6, and what cooperate with cone 6 is a sphere convex lens 7. Sphere convex lens 7 is reduced with diameter that cone 6 contacts the plane to it gradually by sphere, forms a circular cone body. The effect of sphere convex lens 7 is to assemble the cold light light beam. At one layer of overcoat 3(crust of the outer wall of optical fiber 2 and sphere convex lens 7 parcel), this overcoat can be made of plastic or be made with silicon rubber, and the overcoat that wherein is positioned at sphere convex lens one end is thicker, forms the joint 4 that cooperates with the joint hole of cold light light source. Make joint firmly in order to increase frictional resistance, on joint 4 outer walls of the present utility model several flanges 5 are arranged, flange 5 is risen gradually by sphere convex lens 7 one sides and increases, and its purpose is the joint bore dia that is applicable to different model cold light light source.
The utility model has the advantages that, realized the cold light illumination of hard endoscope, reach more than five times thereby improve brightness, and strengthened resolving power, improved the condition of disease clinical diagnosis and treatment by the change of light quality.
Embodiment:
Select the single optical fibers 2 long 2m of φ 0.6mm for use, the one end is made the spheroid 1 of R1.4mm, and the other end is made big end, and to be that φ 1.5mm is high be the cone 6 of 3.32mm, wraps up with uniform one deck silastic material at the outer surface of optical fibers 2.Wherein, thicker at the silastic-layer at joint 4 places, (the joint diameter is φ 7.5mm) has flange 5 everywhere on joint 4, and lip diameter is from being followed successively by φ 8.0mm, φ 8.3mm, φ 8.6mm and φ 8.9mm near sphere convex lens side.The planar ends diameter of sphere convex lens is φ 1.5mm, and the cone 6 of this end and optical fibers 2 is fitted.The sphere of sphere convex lens 7 is R3.93mm.Sphere convex lens thickness is 22.1mm.
The hard endoscope cold light illumination unit of said structure and LG150-2 cold light source fit applications are respond well in the hard esophagoscope.
Claims (2)
1, hard endoscope cold light illumination unit; comprise optical fibers 2, protective layer 3, joint 4; it is characterized in that: optical fibers 2 is for single, and the two ends of optical fibers 2 are made spheroid 1 and cone 6 respectively, in the terminal of joint 4 the sphere convex lens 7 that cooperates with cone 6 is installed.
2, hard according to claim 1 endoscope cold light illumination unit, it is characterized in that: several flanges 5 are arranged on the outer wall of joint 4, and the diameter of flange 5 increases gradually from a side at sphere convex lens 7 places.
