Description
Technical Field
The invention belongs to the technical field of medical instrument manufacturing, and relates to a urethra expansion bougie drainage tube with a step-by-step expansion balloon.
Background
Indwelling catheterization is widely applied in clinic, and is one of the most basic diagnosis and treatment technologies, and is mainly applied to patients who have difficulty in micturition, need to monitor urine volume and urethral stricture, such as urinary retention, bladder cancer, urinary incontinence, after surgical operation, bladder irrigation, severe burns and the like. Indwelling catheters, while solving the above problems, also present certain risks in handling. The difficulty of indwelling the urinary catheter for the patients with traumatic urethral injury, postoperative urethral stricture, senile prostatic hypertrophy and hyperplasia and the like is high, and the failure rate is high.
For the patients who fail to keep the urinary catheter in the conventional way, the traditional treatment method is to use a thinner urethral probe to induce and check, determine the position and the degree of urethral stricture, use a thicker probe to expand the stricture step by step, and finally keep the urinary catheter to drain urine and support the stricture. Patients with severe urethral stricture need to repeat urethral dilation until a catheter of a satisfactory diameter can be indwelling.
The bougie of present clinical application is mostly metal material, passes in and out the urethra bougie repeatedly and keeps somewhere the catheterization, not only increases patient's misery, consumes medical resources, has the damage of normal urethra mucous membrane simultaneously, has complications such as urethral hemorrhage, tear, fracture even, causes great misery for patient.
Disclosure of Invention

the length of the invention is 25cm, and the pipe diameter of the drainage pipe is 8 Fr;
the expansion circumference of the balloon 8 is 12-24 Fr;
the balloon 8 is cylindrical;
the number of the balloons 8 is 4;
the head part 1, the body part 2 and the tail part 3 are made of hard polyethylene materials;
the head 1 and the body 2 are L-shaped;
there are 2 through holes 5.
The invention has the advantages that:
1. the device is provided with four expansion saccules, the saccules can be bent, the urethra is kept running while the stenosis expansion is carried out, and the stimulation to the urethra is small;
2. the probe rod of the device is made of hard polyethylene material, has a thin pipe diameter, and an arc-shaped head end, is easy to pass through urethral stricture and is safer;
3. the urethral dilator can perform urethral dilation while draining urine, can achieve the purposes of draining urine and dilating stricture by one-time operation, does not need to be repeatedly pulled out and replaced, is simple to operate, and simultaneously reduces the damage to urethral mucosa caused by repeated replacement;
4. the device can realize the asymptote of urethral stricture and the continuous balloon dilatation balloon expansion, can not cause the tearing and scar repair of the stricture mucous membrane, and reduces the incidence of complications such as urethral hemorrhage and the like and restenosis caused by violent dilatation.
