Abstract
The utility model relates to a nasoscope with a lighting function. The nasoscope comprises an upper blade and a lower blade. One illuminating optical fiber sleeve pipe is fixed to the inner wall of the upper blade. An illuminating optical fiber is fastened by an optical fiber fixing device fixedly arranged on the nasoscope. The front end of the illuminating optical fiber is penetrated and is exposed out of the front port of the optical fiber sleeve pipe. The utility model has the advantages of simple structure and convenient operation. The nasoscope can provide clear and stable cold light illumination. The nasoscope with a lighting function is very suitable for clinical examination for ear nose throat department doctors.
Description
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of asoscope.
Asoscope is a kind of clinical examination instrument of ent surgery, at present, and the asoscope that department of otorhinolaryngology is used, asoscope itself does not possess illumination functions, rely on the doctor with head lamp or frontal mirror illumination nasal cavity, when the doctor goes the consultation of doctors of other section office, need have extra light source could check nasal cavity, very inconvenient.If arrive the community medicine health check-up, or give first aid to then more apparent inconvenience to the disaster scene.How to design a kind of convenient and practically, light stability, the asoscope clearly of throwing light on are relatively problems of reality.
The purpose of this utility model is to provide a kind of asoscope with illumination functions.
The technical solution of the utility model has been to adopt a kind of asoscope with illumination functions, comprise blade up and down, on the inwall of blade, be fixed with a lighting fiber sleeve pipe, lighting fiber is fastening by the optic fibre fixing device that is fixedly set on the asoscope, and the front end of lighting fiber interts and expose the front port of ferrule.
Described optic fibre fixing device is made of the trip bolt that radially is provided with on fastening sleeve pipe and the fastening sleeve pipe, and fastening telescopic central tube is an optical-fibre channel, and fastening sleeve pipe is fixed in the asoscope rotating shaft by connecting rod.
After in the asoscope blade, being provided with lighting fiber, can make asoscope self have illumination functions, need not outer luminous intensity distribution source, can obtain steady and audible illumination, very easy to use.The optical fibre illumination that carries can make patient avoid the hardship of bulb baking, and it is dazzling tired to make the doctor avoid high light.In addition, lighting fiber is interspersed within the ferrule of blade through behind the optical fiber clamp device, can prevent that optical fiber from skidding off in ferrule in blade opening and closing process, and what help to check carries out smoothly.
Below in conjunction with accompanying drawing this utility model is done further explanation and explanation.
Fig. 1 is a structural representation of the present utility model:
Fig. 2 is the left view of Fig. 1.
As shown in Figure 1 and Figure 2, asoscope of the present utility model is made of handle 5, blade 1, lower blade 9.For automatic light source, on the inwall of blade 1, be welded with ferrule 8.Be interspersed with lighting fiber 4 in the tube chamber of ferrule, the upper end of lighting fiber exposes ferrule upper port 5-10mm.In order to make lighting fiber dehisce to be unlikely slippage from ferrule 8 in the process, on asoscope, also be provided with an optic fibre fixing device at blade up and down.In the present embodiment optic fibre fixing device by on fastening sleeve pipe 3 and the fastening sleeve pipe 3 radially in the screw trip bolt 2 of spinning constitute.Fastening sleeve pipe 3 is fixed in the asoscope rotating shaft 6 by a connecting rod 7.The asoscope that this utility model is described can be made with rustless steel or plastics.Lighting fiber of the present utility model is selected common wick of children's bronchial mirror or the cold light source that uses clinically at present for use, and power supply is Portable DC power supply or ac-dc dual power supply.
