Description

Medical appliance for urethra expansion

The present invention minimizes mucosal wounds of the penis, oral urethra, external urethra, sphincter area urethra, and prostate urethra (hereinafter collectively referred to as "urethra") when the endoscope is inserted into the bladder for bladder endoscopy. In addition, the present invention relates to a medical device for urethra expansion in which the urethra can be easily inserted into the bladder by expanding the urethra when the urethra is narrowed or blocked.

In general, a bladder endoscopy is required to examine the bladder and receive treatment, and for the bladder endoscopy, an endoscope must be inserted through the urethra (penis, oral urethra, external urethra, sphincter area urethra, prostate urethra) to reach the bladder. In this way, when the endoscope passes through the urethra, it causes a wound on the urethral mucosa.

In addition, the urethra has an increasing number of patients with urethral stricture or obstruction due to inflammation such as prostatitis, prostatic hypertrophy, trauma or congenital obstruction due to changes in the habits and diet of modern people, and such people perform bladder endoscopy. In order to do so, you must have a separate urethral dilation surgery.

Therefore, in recent years, the urethra is expanded using a medical device for urethral expansion as shown in FIG. 1 without having to separately undergo the above-described urethral expansion surgery, and then a bladder endoscope is inserted into the bladder through the expanded urethra and examined.

Looking at the configuration of the urethral expansion medical device 10 as described above, a handle 11 is formed at the rear end, and a circular urethral expansion tool 12 is installed at the tip of the handle 11 longer than the length of the urethra. , In front of the urethral dilatation unit 12, a bent portion 13 corresponding to the bent urethra in the lower part of the bladder is formed, and from the bent portion to the tip of the urethral dilatation unit 12 is easily inserted into the patient's urethra The diameter of the urethral dilatation port 12 was formed to be gradually reduced so as to be.

The conventional medical device for urethral expansion 10 as described above is provided in various ways from 3mm to 9.5mm with a difference of 0.5mm in the circular diameter of the urethral expansion device 12, and when using them to expand the patient's urethra The patient's urethra is not inserted into the urethral dilatation unit 12 of the desired diameter at a time to expand, but the urethra is sequentially expanded by sequentially inserting a larger one starting from a small one.

The reason is that if the urethral dilatation tool 12 having the desired diameter is inserted into the patient's urethra and expanded at once, the urethral mucosa is wounded and the patient’s pain increases, so the diameter of the urethral dilatation tool 12 is small. Starting from the start, the urethra is expanded by sequentially inserting a larger one into the urethra, and finally an endoscope is inserted into the expanded urethra to examine the bladder.

At this time, since the urethral dilatation device 12 sequentially inserted into the urethra to expand the urethra is not checked and inserted by the doctor, but is inserted by the doctor's sense in an invisible state, a wound on the urethral mucosa may occur. The wound not only leads to the pain of the speaker, but also has the disadvantage of delaying recovery.

In addition, in the conventional urethral dilatation device 12 as described above, it takes a long time to expand the urethra, and accordingly, the patient's pain time and the doctor's operation time are long.
