Problems solved by technology

[0003] In order to overcome the deficiency that the urethroscope commonly used in clinical practice has no urethral dilating function, and the metal rod urethral probe cannot directly look at the urethra when dilating the urethra, and avoid serious complications caused by dilating the urethra, the present invention provides a urethroscope with a urethral dilating function, which has The function of ordinary urethroscopy, at the same time, urethral dilatation can be performed under direct vision for patients with urethral stricture

specific Embodiment approach

[0012] Specific embodiments: a urethroscope with urethral expansion function, including a detachable outer sheath 1 and an endoscope system, characterized in that the outer sheath 1 is made of transparent hard plastic material, disposable and sterile. Divided into different models, it is hollow (including two longitudinal channels 2 and 3). The head end is round bullet-shaped (the tip is slightly flattened 4), and the front section is slightly curved. On one side of the rear end, there is a flushing end 6 communicating with the small channel 3 in the outer sheath, and the small channel opens at the tip 5; in the middle of the rear end, there is an endoscope system mirror body 7 entering the large channel 2, and the large channel to the tip is in the shape of a lens 4 . The mirror body of the endoscope system used can be bent, and the same endoscope is applicable to different types of outer sheaths. The endoscope system is an integrated structure (similar to an industrial end...

Abstract

The invention discloses a urethroscope with an urethral dilatation function. The urethroscope comprises a detachable outer sheath and an endoscope system, wherein the outer sheath is prepared by a transparent hard plastic material with one-time application and sterility, is divided into different models, and is hollow (including vertical large and small channels); a head end is rounded in bullet shape (the tip is slightly flat) and a front section is slightly curved; one side of a rear end has a flushing end communicating with the small channel in the outer sheath, and the small channel is open at the head end; an endoscope system mirror body at middle of the rear end enters the large channel, and the large channel to the tip end is lenticular. The endoscope system is flexible, and the same endoscope is suitable for different types of the outer sheaths. The endoscope system has an integrated structure (like an industrial endoscope system), including an objective lens, a light source, fiber optic fiber, and a display, which can be reused and used without disinfection. The mirror body extends from the rear end of the outer sheath into the longitudinal large passage in the outer sheath to a outer sheath tip lens, and has an own light source and a display system. The urethroscope solves the functions of common urethroscope direct vision examination and dilatation of urethral stricture, and has the characteristics of clear intraoperative vision, simple structure, and easy learning and use.

Description

technical field [0001] The invention belongs to the field of urological medical equipment, and has the function of a common urethroscope, and also has the function of dilating the urethra for examining and treating urethral stricture under direct vision. Background technique [0002] Urethroscopy has an irreplaceable role in diagnosing urethral lesions and has been widely used in urology. However, urethroscopes currently in clinical use have no urethral expansion function and are not suitable for patients with urethral strictures. The urethra is prone to urethral stricture after trauma and surgery, especially in male patients. It can occur in all age groups. There is no special treatment method except for reoperation and urethral dilatation. At present, the commonly used urethral dilator is a metal rod-type urethral probe. However, the urethral probe cannot look directly at the urethra when dilating. , perforation, bleeding, etc., leading to complicated urethra, and finally...
