Abstract

The utility model discloses an optical fiber lighting front nasoscope. The utility model is composed of a left and a right supporting arc-shaped sheets 1, 1', a handle 2, a rotary shaft 3 and an elastic sheet 4, wherein, the left and the right supporting arc-shaped sheets 1, 1' are respectively composed of an inner layer and an outer layer. Each outer layer is a stainless steel sheet 5, and each inner layer is a transparent plastic sheet 6. The inner sides of the stainless steel sheets 5 are provided with reflecting bulge rings 7 which are reflected forwards. Optical fiber bundles 8 are clamped between the inner and the outer layers. The handle 2 is provided with a hollow cavity tube. A light emitting lamp 9 is arranged inside an inner cavity of the front end of the handle 2. The optical fiber bundles 8 are extended to the insides between the inner and the outer layers of the left and the right supporting arc-shaped sheets 1, 1' from the front side of the light emitting lamp 9. The optical fiber lighting front nasoscope has the advantages that the light source can be carried self, the operation is labor-saving, the use is convenient, and the utility model is not restricted by a power supply. All positions inside a nasal cavity can be clearly observed. The utility model can be widely used for the examination of an E. N. T. department.

Description

Asoscope before the optical fibre illumination

Technical field

This utility model relates to a kind of improvement of preceding asoscope, and asoscope before specifically a kind of optical fibre illumination is applicable to otorhinolaryngologic inspection.

Background technology

Preceding asoscope is the inspection utensil that a kind of department of otorhinolaryngology is used, constitute by the left and right arc-like sheet, handle, turning cylinder, flexure strip of strutting, the left and right awl tubular that forms when strutting the arc-like sheet make-up, the doctor is when making nasal cavity and check to patient, and the doctor need put on frontal mirror, the left and right arc-like sheet that struts is put into nasal cavity, hold handle, strut nasal cavity, by the bulb source of a side, by frontal mirror luminous reflectance is advanced nasal cavity, observe.Because therefore the outside intense light source of employing is subjected to the restriction of power supply, high light is easily stabbed eyes, wastes energy, and then can not work when having electricity, influences patient's treatment opportunity, and head band uses inconvenience, the eyes fatiguability on head in addition.

Summary of the invention

The restriction that the purpose of this utility model is a kind of automatic light source to be provided, not to be subjected to power supply, easy to operate, can improve nasal cavity and observe asoscope before the optical fibre illumination of illuminance.

For reaching above purpose, the technical scheme that this utility model adopted is: asoscope before this optical fibre illumination, by a left side, the right side struts arc-like sheet, handle, turning cylinder, flexure strip constitutes, a left side, when strutting the arc-like sheet make-up, the right side forms an awl tubular, a left side, the right side struts arc-like sheet respectively by interior, outer two-layer composition, skin is a stainless steel substrates, internal layer is a transparent plastic sheet, be provided with reflection bulge loop to front-reflection in the inboard of stainless steel substrates, in, accompany fibre-optic bundle between the skin, handle is the cavity pipe, and electroluminescent lamp is located in the front end cavity of handle, and fibre-optic bundle extends a left side from the electroluminescent lamp front side, the right side strut arc-like sheet in, in the outside sandwich.This utility model is also implemented by following measure: the end of fibre-optic bundle in a row is fixed on the front side of the reflection bulge loop on the stainless steel substrates, so that light is to front-reflection, electroluminescent lamp is miniature spot light lamp bulb, battery is located in the cavity at handle middle part, lead one end is connected with battery, the other end is connected with electroluminescent lamp, establishes switch at the middle part of battery.When using this utility model, can directly insert nasal cavity, turn on the power switch strutting arc-like sheet, can be by fibre-optic bundle with illumination to the nasal cavity inboard, directly spy on the nasal cavity pathological changes.

The beneficial effects of the utility model are: with existing before asoscope compare, can automatic light source, rapid operation, easy to use, the restriction that is not subjected to power supply, can observe each position of nasal cavity clearly.
