Embodiment Construction

[0012] As shown in the figure: a flexible bladder endoscope, including a light source, an optical coupling component, a light-transmitting optical fiber 1, an imaging optical fiber 2, an image-transmitting optical fiber, an image coupling component, and an image display device. The optical fiber 1 and the imaging optical fiber 2 are connected to the image coupling component, and the image coupling component is connected to the image display device through the image transmission optical fiber. The imaging optical fiber 2 and the light transmission optical fiber 1 are all arranged in the sheath tube. ) conventional structure, the light generated by the light source is transmitted to the interior of the bladder to provide illumination light, and the imaging device forms an image of the tissue in the bladder, which is convenient for medical personnel to diagnose. The sheath tube is composed of a sheath tube I3 and a sheath tube II4, the sheath tube I3 is sleeved in the shell 11, th...

Abstract

The invention relates to a bendable and stretchable bladder endoscope which comprises a light source, a light transmission optical fiber, an imaging optical fiber, an image transmission optical fiber and an image display device. The imaging optical fiber and the light transmission optical fiber are both arranged inside sheath tubes, the sheath tubes comprise the sheath tube I and the sheath tube II which are mutually hinged, and two sliding chutes which are formed in the axial direction are symmetrically formed in the outer wall of the sheath tube I. The endoscope further comprises a swing driving device, and the swing driving device is used for controlling swing of the sheath tube II 4 in a far-end mode. The head of the bladder endoscope can swing in varying degrees according to needs, the bladder endoscope can be suitable for diagnosing any part in a bladder, a non-blind area view can be achieved in the bladder, the defects of an existing bladder endoscope are overcome, the definite diagnosis rate of the bladder endoscope is obviously improved, the adjusting manner is a pure mechanical principle adjusting manner, energy can also be saved, the complexity of the device is lowered, and feasibility is increased.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flexible bladder endoscope. Background technique [0002] With the development of endoscopic technology, cystoscopy has become the main method for the diagnosis of urinary system diseases. Because it can observe the size and location of lesions under direct vision, it has high diagnostic value for bladder tumors and complex stones, and can determine the surgical plan. It is of great significance, and it can treat diseases at the same time with electric cutter or lithotripsy device. However, because the existing cystoscope is a straight rigid mirror, which cannot be bent, it has become a blind spot for the straight cystoscope to target the anterior side wall of the bladder and the lesions near the internal opening of the urethra, thereby increasing the missed diagnosis rate and increasing the pain and burden of the patient. Although the application of soft mirrors h...
