Novel urethral stenosis expanding and catheter indwelling assisting device

Abstract

The invention discloses a novel urethral stenosis expanding and catheter indwelling assisting device, which comprises a urethral probe, a zebra guide wire and a catheter puncture nail. The urethral probe is provided with a hollow cavity, the front end of the urethral probe is provided with an opening, the side wall of the front end of the urethral probe is provided with a side hole, and the rear end of the urethral probe is respectively provided with an independent guide wire imbedding tube and an independent liquid medicine injection tube; the axis of the guide wire imbedding tube is consistent with that of the urethra exploring tube, and the liquid medicine injection tube is located on one side of the guide wire imbedding tube; an expansion balloon is further arranged on the outer side wall of the front end of the urethra exploring tube and connected with a balloon communicating tube arranged in the hollow cavity, and the rear end of the balloon communicating tube extends out of theurethra exploring tube and expands to form an expansion balloon tube. The device is simple in structure, reasonable in design and easy and convenient to operate, urethra mucous membrane injuries caused by repeated urethra expansion are avoided, time is saved for clinicians, the operation difficulty is lowered, and pains and risks of patients are reduced.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, and more specifically, relates to a novel device for dilating urethral stricture and assisting indwelling catheter. Background technique [0002] Urinary catheterization is a commonly used medical operation in clinical medical work. It is a routine preoperative preparation for surgical patients and an important means of urination for patients with dysuria. Urethral stricture is a common disease in urology, mainly seen in male patients with urethral trauma, inflammation, scar formation after surgery, and moderate to severe benign prostatic hyperplasia. For this part of the patients, the conventional catheterization cannot successfully place the catheter to the bladder, and metal urethral bougies are often used in clinical medical work to expand the narrow urethra many times. This traditional urethral expansion method has several shortcomings: first, Incrementally use different...

Problems solved by technology

For this part of the patients, the conventional catheterization cannot successfully place the catheter to the bladder, and metal urethral bougies are often used in clinical medical work to expand the narrow urethra many times. This traditional urethral expansion method has several shortcomings: first, Incrementally use different types of urethral bougies to dilate the urethra sequentially, the operation is cumbersome, and will cause discomfort and pain to the patient; secondly, when a large-sized urethral bougie enters the urethral stricture longitudinally, it may puncture the normal tissue next to the urethra , causing false urethra
