Released on May. 26, 2022

Ureteroscope is a medical device used for minimally invasive diagnosis and treatment in urology. It is composed of optical fiber, working lumen and various working accessories for different purposes. The diameter is small and the length is 35 to 45 cm. Ureteroscopy is a slender endoscope that enters the ureter with a diameter of 0.2 to 0.5 cm through the urethra, bladder, and ureteral orifice. After connecting the monitoring equipment, the lesions in the ureter can be clearly observed, and then inserted through the working cavity. Different instruments for diagnosing and treating ureteral diseases.

Common faults and solutions of ureteroscope:

Fault 1. Image condition: blurred water, shadow, dust; solution: replace the internal internal optical components;

Fault 2. Beam: yellow and broken wire, burning and collapse, insufficient brightness; solution: replace the beam;

Failure 3. Mirror tube: bend, break, dent, fall off; solution: replace the mirror tube;

Failure 4. Instrument channel: wear and tear, deformation; solution: replace the instrument channel;

Fault 5. Objective lens: degumming, wear and tear; solution: replace the objective lens;

Fault 6. Light cone: burning black, yellow, falling off and missing; solution: replace the light cone;

Fault 7. Mirror bridge assembly: fall off, bayonet broken; solution: replace the mirror bridge assembly;

Fault 8. Eyepiece protective sheet: cracked, chipped, or missing; solution: replace the eyepiece protective sheet;

Fault 9. Eye mask: cracked, broken; solution: replace the eyepiece cover;

At present, ureteroscopy is mainly used for the treatment of ureteral calculi, ureteral strictures, and the diagnosis of ureteral tumors. It improves the level of diagnosis and treatment of ureteral diseases, significantly reduces the suffering of patients, shortens the hospitalization time of patients, and reduces the cost of treatment.
