Bronchoscope fixing system with angle adjustability

Abstract

The invention belongs to the technical field of medical apparatus and instruments and discloses a bronchoscope fixing system with angle adjustability. The bronchoscope fixing system is provided with asoft fiber pipe, wherein the tail end of the soft fiber pipe is fixed at the head end of an operation handle, an eyepiece is fixed at the tail end of the operation handle through a thread, and the side surface of the operation handle is communicated with a conduit hose; an optical fiber is arranged in the middle of the soft fiber pipe and coated with a protective layer, and the gap between the optical fiber and the protective layer is filled with an electrorheological fluid layer. An electrorheological fluid material is added on the basis of the conventional mature soft fiber bronchoscope, anelectrorheological fluid becomes solid when the electric field intensity of the electrorheological fluid is higher than a critical value, the body of the bronchoscope can become harder or return to softness by changing the current of the electrorheological fluid layer in the soft fiber pipe, and the head end angle of the soft fiber pipe can be rotated to be adjusted by the operation handle.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an angle-adjustable bronchoscope fixing system. Background technique [0002] Bronchoscope is a medical device suitable for observation of lung lobe, segmental and subsegmental bronchial lesions, biopsy sampling, bacteriological and cytological examination, and can cooperate with TV system for photography, teaching and dynamic recording. The bronchoscope is equipped with a biopsy sampling mechanism, which can help to detect early lesions, and can perform in vivo surgery such as polyp removal. It is a good precision instrument for the research of bronchial and lung diseases, postoperative examination, etc., and is a must for bronchial lesion inspection. Indispensable medical equipment. [0003] At present, the traditional bronchoscope is a hard fiber bronchoscope and a soft fiber bronchoscope, but because the hard fiber bronchoscope is a rigid object, the soft fiber bronc...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problem in the prior art is that the angle of the traditional bronchoscope cannot be adjusted at will, which brings inconvenience to the treatment and diagnosis.
