Description
Technical Field
The utility model belongs to the technical field of medical instrument is relevant, concretely relates to novel urethral dilator of supplementary catheterization.
Background
The prostatic hyperplasia is a common disease in urinary surgery, and is a disease that the glandular connective tissue and smooth muscle tissue of the middle lobe or the inverted lobe under the posterior urethral mucosa are gradually proliferated under the action of factors such as sex hormone balance imbalance and the like of a human body to form a multiple spherical nodule, so that a series of functional disorders occur to the urethra, the bladder and the kidney. The main symptoms are as follows: 1. inability to urinate, thin urinary cords and urine droplets; 2. urinary retention: in the late stage of patients with severe prostatic hyperplasia, acute urine retention can occur due to the failure of urine discharge caused by cold catching, drinking, too long urine holding time or infection when obstruction is serious; 3. hematuria; 4. acute urinary tract infection; 5. abnormal urination: the problem that the prostatic hyperplasia is large and stimulates the posterior urethra and the bladder neck to be pressed in the early stage is common, so that frequent urination, urgent urination and the like are caused, in addition, urgent urination is caused, but the urgent urination cannot be rapidly discharged, the urination is not as smooth as before, the time is long, the feeling of incomplete urination is caused, the urination is difficult, and the like.
Male urethral stricture is also a common disease in urology surgery and can be classified into congenital, inflammatory and traumatic 3 types according to the etiology. Severe urethral stricture can cause upper urinary tract dropsy and renal function damage, and some cases can be complicated with periurethritis and periurethral abscess, even puncture to scrotum perineum to form a long-lasting urethral fistula, and also often complicated with urinary tract and reproductive tract infection.
Existing treatment regimens are often catheterization in addressing the acute urinary retention caused by prostatic hyperplasia and urethral stricture described above. In the present situation, patients with prostatic hyperplasia and urethral stricture, especially patients with long-term disease, the emergency catheterization is easy to fail. In order to further solve the symptoms of acute urinary retention of patients, a method for emergency cystostomy is selected after urinary catheterization fails, and the problems of great pain, short time and the like exist when the symptoms of acute urinary retention are treated in the emergency cystostomy. The idea of the novel urethral dilator for assisting in urethral catheterization is that the urethral dilator can assist in urination and assisting in urethral catheterization while dilating the urethra. After the rigid urethra dilator is placed into the urethra and the bladder, urine can be led out from the placing channel to quickly improve the symptoms of acute urinary retention of a patient, and then a guide wire can be placed into the urethra through the placing channel and further sent into the catheter through the guide wire. After the process, the symptoms of acute urinary retention can be quickly solved, the problem of difficult catheterization can be solved, and secondary treatment such as bladder fistulization can be avoided. The prior art of urethral dilators has the following problems: the urethral dilator can only perform urethral dilation, only solves the problem of urethral stricture of a patient, but cannot simultaneously solve the problem of difficult catheterization caused by urethral stricture, prostatic hyperplasia and the like of the patient.
