Cystoscope with swinging head end

Abstract

The invention relates to a cystoscope with a swinging head end. The cystoscope comprises a light source, a light transmission optical fiber, an imaging optical fiber, an image transmission optical fiber and an image display device, wherein the imaging optical fiber and the light transmission optical fiber are arranged in a sheath tube which is composed of a sheath tube body I and a sheath tube body II, the sheath tube body I is hinged to the sheath tube body II, and the outer wall of the sheath tube body I is provided with a sliding groove in the axial direction. An endoscope further comprises a swinging drive device which mainly comprises a gear, a rack and a push-pull piece, the rack is stuck in the sliding groove, the gear is mutually meshed with the rack and can freely rotate, and the end, away from the gear, of the rack is connected with the sheath tube body II through the push-pull piece. According to the cystoscope, the head end can swing in different degrees according to needs, the cystoscope is suitable for diagnosing any portion in the bladder, no blind areas exist in the bladder in the view, defects of an existing cystoscope are made up for, the diagnosis confirmation rate of the cystoscope is improved, a regulating mode accords with the pure mechanical principle, energy can be saved, complication of the cystoscope is reduced, and feasibility is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cystoscope with a swingable head end. 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...
