ENDOSCOPE OPERATING SHEATH FOR UROLOGICAL SURGERY

An endoscope operating endoscopy sheath (2) for urological surgery, comprising a core rod (3) that can be disposed in the endoscope operating endoscopy sheath (2) and axially slides relative to the endoscope operating endoscopy sheath (2). The core rod (3) is internally provided with a guide wire passage (5), a water injection passage (6), and an imaging passage (7) that extend from the rear end to the front end of the core rod (3); an endoscope endoscopy handle (1) is provided with a guide wire connector (8), a water injection connector (9), and an endoscope connector (10) for respectively guiding a guide wire, water, and an endoscope into the guide wire passage (5), the water injection passage (6), and the imaging passage (7). The endoscope operating endoscopy sheath (2) and the core rod (3) enter a human body along the guide wire; the core rod (3) is drawn out after reaching a lesion site; then a flexible cystoscope is put into the endoscope operating endoscopy sheath (2); the endoscope operating endoscopy sheath (2) and the flexible cystoscope are operated to observe the lesion site and cooperate with surgical instruments for performing surgery. The method is simple and easy to implement; the endoscope operating endoscopy sheath can be widely applied to renal pelvis and renal caliceal calculi surgery, and may serve as a ureterectasia visualization endoscopy sheath, and is applicable to, but not limited to, cardiovascular intervention, gynecological surgery, thyroid gland and mammary gland surgery, neurosurgery and orthopedic surgery, and other unmentioned related clinical medical fields.
