Urethral dilatation catheter for urethral stenosis and using method thereof

Abstract

The invention discloses a urethral dilatation catheter for urethral stenosis and a using method of the urethral dilatation catheter, and belongs to the technical field of medical instruments. The urethral dilatation catheter for urethral stenosis comprises a catheter. The catheter is connected with a conical block; the catheter is connected with a drainage tube, a first water injection tube, a second water injection tube, a third water injection tube, a fourth water injection tube and a fifth water injection tube; the fifth water injection tube is connected with a valve; the outer wall of thecatheter is sequentially connected with a balloon, a first airbag, a second airbag, a third airbag and a fourth airbag; the first water injection tube is connected with the first airbag, the second water injection tube is connected with the second airbag, the third water injection tube is connected with the third airbag, the fourth water injection tube is connected with the fourth airbag, and thefifth water injection tube is connected with the balloon; and the drainage tube penetrates through the outer wall of the catheter and is provided with a sixth through hole. According to the invention,split type transverse expansion is used for relieving the pain of a patient and preventing infection, bleeding and artificial tracts; and the independently controlled airbags are used for targeted expansion, so that the pain of the patient is relieved and the medical compliance of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a urethral dilatation catheter for urethral stricture and a usage method thereof. Background technique [0002] Urethral stricture is a common clinical urological disease, with more male patients; in recent years, the incidence of urethral stricture caused by traffic accidents, intracavitary surgery, urinary system infection, etc. has been increasing, which seriously affects the normal life of patients; urethral stricture The main manifestations are poor urination, dysuria, and thinning of urine stream. With the advancement of medicine, many new methods for the treatment of urethral stricture have emerged. The trauma is small, and the incidence of complications is lower, which has greater advantages in clinical treatment, and the scope of application is gradually expanding. [0003] At present, the most widely used method is intracavitary urethral stricture internal inci...

AI Technical Summary

Problems solved by technology

[0003] At present, the most widely used method is intracavitary urethral stricture internal incision, and regular urethral dilatation after surgery. Currently, metal dilators are used clinically for urethral dilation, which poses safety hazards to sensitive parts of patients, and there are many complications during the operation. For example, bleeding, pain, infection, and false tract formation. On the one hand, once bleeding or infection occurs, urine stimulates the wound to form new scars, which will affect the curative effect of urethral stricture. On the other hand, most patients have poor medical compliance due to pain. Rather endure dysuria than perform urethral dilation, which leads to a high recurrence rate and poor cure rate of urethral strictures, and most patients have to accept the reality of urinary diversion; therefore, there is a need for a method that avoids infection and helps relieve Painful urethral dilation catheter
