The invention relates to a flexible bladder endoscope, which comprises a light source, a light-transmitting optical fiber, an imaging optical fiber, an image-transmitting optical fiber and an image display device. The outer wall of the sheath I is symmetrically provided with two sliding slots arranged in the axial direction, and the endoscope also includes a swing driving device, which is used to control the swing of the sheath II4 from the distal end. The endoscope used for the bladder of the present invention can swing its head end to different degrees according to the needs, and can be applied to the diagnosis of any part of the bladder, and can achieve no blind area in the vision of the bladder, making up for the existing cystoscope. Insufficiently, the diagnostic rate of the cystoscope is significantly improved, and its adjustment method is purely mechanical, which can also save energy, reduce the complexity of the device, and increase the feasibility.
Description
Technical field
