Embodiment Construction

[0014] As shown in the figure: a flexible endoscope for bladder, including light source, optical coupling part, light transmission fiber 1, imaging fiber 2, image transmission fiber, image coupling part and image display device, the light source passes through the optical coupling part Connect the light-transmitting optical fiber 1, the imaging optical fiber 2 is connected with the image coupling component, the image coupling component is connected to the image display device through the image-transmitting optical fiber, the imaging optical fiber 2 and the light-transmitting optical fiber 1 are all arranged in the sheath, and the above structure is a cystoscope ( The conventional structure of the endoscope) transmits the light generated by the light source 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 ...

Abstract

The invention relates to a bendable endoscope for a bladder. The bendable endoscope for the bladder comprises a light source, a light transmitting optical fiber, an imaging optical fiber, an image transmitting optical fiber and an image display device. The imaging optical fiber and the light transmitting optical fiber are both arranged in sheaths. The sheaths comprise the sheath I and the sheath II which are hinged to each other. Two sliding grooves which are arranged axially are symmetrically formed in the outer wall of the sheath I. The bendable endoscope further comprises a swinging driving device. The swinging driving device is used for controlling the sheath II 4 to swing at the far end. According to the bendable endoscope for the bladder, the head end of the bendable endoscope can swing to different degrees according to needs, the bendable endoscope is also suitable for the diagnosis of any part in the bladder, no blind area exists in the vision in the bladder, the defect of an existing cystoscope is overcome, and the rate of definite diagnoses of the cystoscope is remarkably improved; due to the fact that the adjusting method of the bendable endoscope is according to pure mechanical principles, energy can also be saved, the complexity of the bendable endoscope is lowered, and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flexible endoscope for bladder. 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 mirro...
