Device capable of eliminating water mist and dirt on bronchofiberscope lens and keeping clear view

Abstract

The invention discloses a device capable of eliminating water mist and dirt on a bronchofiberscope lens and keeping a clear visual field, which is characterized by comprising an outer protective cover, a transparent top cover, an upper scraping and sweeping part, a lower scraping and sweeping part, a scraping and sweeping part connecting structure, an electric heating wire and a control rod, the upper end and the lower end of the outer protective cover are open, the transparent top cover is integrally connected to the opening in the upper end, the upper scraping and sweeping part and the lower scraping and sweeping part are movably connected to the transparent top cover through a scraping and sweeping part connecting structure, and the upper scraping and sweeping part and the lower scraping and sweeping part are located on the upper face and the lower face of the transparent top cover respectively. An interlayer is arranged in the transparent top cover, and a circle of electric heating wire is arranged in the interlayer; the upper end of the control rod is detachably connected with the lower end of the scraping and sweeping part connecting structure; the device is detachably arranged at the end part of the bronchofiberscope and is used for protecting a lens of the bronchofiberscope without influencing normal visual field observation; the dirt or water mist in the visual field can be removed in vitro through a control structure of the device; the lens is protected, and the service life of the lens is prolonged.

Description

technical field [0001] The invention belongs to the technical field of auxiliary devices for bronchoscopic examination, and in particular relates to a device capable of eliminating water mist and dirt from the lens of a bronchoscope and maintaining a clear field of view. Background technique [0002] Fiber bronchoscope is suitable for observation of lung lobe, segmental and subsegmental bronchial lesions, biopsy sampling, bacteriological and cytological examination, and can be used for photography, teaching and dynamic recording with TV system. The bronchoscope is equipped with biopsy sampling and deconstruction, which can help to detect early lesions, and can perform in vivo surgery such as polyp removal. It is a good precision instrument for bronchial and lung disease research, postoperative examination, etc.; [0003] However, in the process of fiberoptic bronchoscopy, the lens of the fiberoptic bronchoscope will be blocked due to the condensation of water mist in the lun...

Problems solved by technology

[0003] However, in the process of fiberoptic bronchoscopy, the lens of the fiberoptic bronchoscope will be blocked due to the condensation of water mist in the lungs, blood stains and other dirt, which cannot provide a clear view and affect the normal operation or inspection process; currently there is no A more effective device that can be adapted to remove water mist and dirt on the bronchoscope without affecting the normal use of the bronchoscope
