Superfine fiberscope system with guiding function and using method thereof

Abstract

The invention discloses a superfine fiberscope system with a guiding function, which comprises a fiberscope, a controllable bending angle sheath tube, a control handle and a rotating control damping piece. The fiberscope holding handle of the fiberscope is connected with an optical cable through an optical cable connecting seat; the fiberscope holding handle of the fiberscope is connected with animage amplifying camera; the image amplifying camera is connected with a cable through a cable connecting seat; the fiberscope body of the fiberscope passes through the controllable bending angle sheath tube through the control handle; the control handle controls the locking state between the fiberscope body and the controllable bending angle sheath tube through the matching connection between thecontrol handle and the rotating control damping piece; the outer diameter of the fiberscope body is smaller than the inner diameter of the controllable bending angle sheath tube. The system can reachthe lung edge of the 11-15 level lung bronchus to acquire the image information of the natural cavity of a human body through simple operation. The invention also discloses a use method of the superfine fiberscope system with the guiding function.

Description

technical field [0001] The invention relates to an endoscope used in minimally invasive surgical medicine for internal inspection, diagnosis and treatment of a human body, in particular to an ultrafine fiberscope system with a guiding function. The invention also relates to a method for using the microfiber mirror system with guiding function. Background technique [0002] Lung cancer has become the first cause of death from malignant tumors in China, and it is also one of the most common and deadliest cancers in the world. According to statistics, the incidence of lung cancer in China is increasing by more than 20% every year. In 2015, the incidence of lung cancer in China was 50.93 / 100,000, and the death rate was 43.24 / 100,000; the incidence of lung cancer in women was 22.4 / 100,000, and the death rate was 17.78 / 100,000. [0003] For the diagnosis of lung cancer, the current commonly used method is to first find the lesion through imaging examinations such as X-ray film, C...

Problems solved by technology

[0004] Among the existing bronchoscopes, the outer diameter of the thinnest bronchoscope can reach 2.6 mm, but its working channel is only about 1 mm. Although it can reach the 10th level of the pulmonary bronchus, the biopsy tissue that can be obtained is very small, and it is difficult to Deeper tissue examination is done by, for example, OCT probe, so it cannot be used for pathological examination of tracheal lesions at the edge of the lung, and cannot be used for the diagnosis of peripheral lung lesions

[0005] At present, the electromagnetic navigation bronchoscopy system can also be used for the exploration of the pulmonary edge trachea, but the use of this system must rely on a bronchoscope. Due to the limitation of the outer diameter of the bronchoscope, the bronchi in the edge area of ​​the lung cannot be directly observed. Expensive and not conducive to popularization
