Description

technical field [0001] The invention belongs to the technical field of medical device manufacturing, and relates to a urethral expansion bougie drainage tube with a step-by-step expansion balloon. Background technique [0002] Indwelling catheterization is widely used clinically and is one of the most basic diagnosis and treatment techniques. It is mainly used in urinary retention, bladder cancer, urinary incontinence, after surgery, bladder flushing, severe burns, etc., where it is difficult to urinate, and urine output and urethra need to be monitored. narrow patients. Although indwelling catheters can solve the above problems, there are certain risks in the operation. Traumatic urethral injury, postoperative urethral stricture, elderly prostatic hypertrophy and other populations are difficult to indwell the urinary catheter, and the failure rate is high. [0003] For the above-mentioned patients who failed the routine indwelling catheter, the traditional treatment metho...
