Adjustable flexible nasal endoscope

Abstract

An adjustable flexible nasal endoscope belongs to the technical field of medical apparatus and instruments, and can solve the problem that the conventional nasal endoscopes are complex in structure and are poor in stability, hard nasal endoscopes cannot flex according to a natural cavity structure, expansion ball bags cannot perform expansion treatment in a visible situation and cannot directly perform washing and medicine changing in sinus cavities, and the application effect is poor. The adjustable flexible nasal endoscope includes a hand-held portion; a winding mechanism arranged on the back of the hand-held portion; a three-cavity flexible pipe passing through the hand-held portion and extending out from a front part, wherein a power channel, an optical fiber imaging channel, and an apparatus channel are arranged in the three-cavity flexible pipe in the length direction in parallel; a steel cap arranged on one end extending out of a front cover, of the three-cavity flexible pipe; a steel pipe sleeving the three-cavity flexible pipe, wherein one end of the steel pipe and the front end of the hand-held portion form a slide fit; a micro steel pipe arranged in a power channel of the three-cavity flexible pipe, wherein one end of the micro steel pipe is fixedly connected to a fixing block in a back cover, and the other end of the micro steel pipe is fixed on an end portion of the three-cavity flexible pipe; a steel wire arranged in the micro steel pipe, wherein one end of the steel wire is fixed on one end near the steel cap, of the micro steel pipe, and the other end of the steel wire extends out of the micro steel pipe and passes through the fixing block, and is connected to the winding mechanism through a guide wheel, and the working length of the steel wire can be changed through the winding mechanism.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an adjustable and bendable sinus mirror. Background technique [0002] At present, the methods for treating rhinitis, sinusitis, and sinus lesions include drug therapy, surgical therapy, laser or microwave therapy, low-temperature plasma radiofrequency therapy, and balloon dilatation contrast catheter flushing. However, these treatment methods are either destructive or ineffective, and may even cause greater secondary harm to the patient, as well as cause drug dependence, drug-induced rhinitis, and nasal mucosal damage. Treatment also requires the help of other aids. [0003] An endoscope is a tube equipped with light, which can enter the human body through the natural orifice of the human body or a small incision made by surgery. After being illuminated by the light guide tube, the image is collected for analysis, which is convenient for doctors to diagnose and treat; w...

Problems solved by technology

[0004] The purpose of the present invention is to propose an adjustable and bendable sinus mirror, which solves the problems in the prior art that the structure is complex, the stability is poor, the hard sinus mirror cannot be bent according to the structure of the natural cavity of the human body, and the expansion balloon cannot be seen. Lower dilatation treatment, unable to directly wash and change the sinus cavity, poor application effect
