The front end of the inner cavity is spherical, the rear end of the inner cavity is connected with the filamentous soft illuminating light, and the other parts of the inner cavity except the two mounting holes are used for emitting light. The spherical surface has better diffusivity and larger luminous area, thereby improving the image quality and reducing the unfavorable conditions of misjudgment of illness state and the like caused by image dark areas.

The image of the front end part is collected and transmitted to the display equipment through a photographing and video recording button on the operation part, the image is high in definition, the field angle of the wide-angle lens is less than or equal to 110 degrees, and the depth of field is 2-50 mm.

More preferably, the main hose is formed of a stainless steel pipe, and a spiral cut groove is formed in an outer circumferential surface of the stainless steel net. When the endoscope is inserted into a human body cavity for operation examination, the insertion part of the endoscope needs to rotate in the radial direction under the condition of searching an inlet of a natural cavity of the human body and the like, so that the radial torsion ratio of the main hose of the endoscope is close to 1:1, which is optimal. If the main hose adopts the spiral rigid belt, when the main hose is subjected to axial force, the main hose can be stretched or compressed, so that the main hose can also be slightly stretched. When radial rotation is needed, due to the elasticity of the spiral steel belt, the radial torsion of the two ends of the spiral steel belt is difficult to ensure synchronous unification. The utility model adopts thin-wall stainless steel pipes to be subjected to quenching and tempering to enhance the fatigue resistance of the thin-wall stainless steel pipes, and then the thin-wall stainless steel pipes are subjected to laser cutting to form a spiral array groove shape, so that the expansion amount of the main hose is basically 0, and the radial torsion is synchronous and uniform.

Preferably, the area of the light-emitting region is 1/2-3/5 of the whole spherical area.

Preferably, the operation part is provided with an attraction button, a photographing and recording button and a bending direction adjusting deflector rod, the attraction button is connected with an instrument channel in the endoscope body through an attraction pipe, the photographing and recording button is connected with an image sensor at the front end part and external display equipment through an electric wire, and the bending direction adjusting deflector rod is connected with the bending part through a rope. The bending direction-adjusting deflector rod on the operation part can sensitively control the tail section to realize active bending, and the upper and lower bending angles can reach 210 degrees. The passive bending design of the insertion section is convenient for entering into the branch trachea with a small angle.

Preferably, the operation portion is provided with a leakage detection interface, and the leakage detection interface is externally connected with an air pressure boosting device. The leak detector is inflated, pressurized and used for leak detection, the tightness of components such as a mirror tube and a channel can be detected, damage to the endoscope can be prevented from gradual change, early maintenance can be found early, and the use or maintenance cost is reduced.

Therefore, the soft electronic bronchoscope has the following advantages: the structure is simple, the illumination area is large, and the illumination effect is good, so that the image quality is improved, a doctor can see a focus part more clearly, and the diagnosis accuracy is improved; the bending effect of the bending part is better, and the radial torsion is synchronous and uniform.
