Special catheter for prostatic hyperplasia patients[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of urology, in particular to a special catheter for patients with prostatic hyperplasia.
[ background of the invention ]
It is known that prostatic hyperplasia is a common disease, and the prostatic hyperplasia can block the urethra, thereby causing unsmooth urination, when a patient is in hospital, the patient needs to be assisted to urinate through a catheter due to bed rest, however, when a patient suffering from prostatic hyperplasia is hospitalized, the conventional catheter is difficult to enter the body of the patient under the condition of enlarged prostate, if forced, the urethral wall of the patient is damaged, causing great pain to the patient, and in such a case, even experienced surgical specialists have difficulty inserting the current catheters into the patient's body, eventually assisting the patient in urination only by means of bladder puncture, such an operation not only increases the treatment cost of the patient, but also causes a certain damage to the body of the patient, and the patent numbers are: CN88219869.6, filing date 1988.08.12, with patent names: a prostatic urethra expander, which is specifically implemented by expanding a pressure-resistant air bag through inflation so as to achieve the aim of expanding the prostatic urethra, but the method cannot well expand the urethra at the prostatic hyperplasia part in practice, the urethra becomes bent due to the compression of the prostatic hyperplasia, the pressure-resistant air bag in the patent is opened at one time, so that the urethra at one point can be expanded, the urethra at the whole prostatic hyperplasia part is difficult to expand, the urethra at the prostatic hyperplasia part is difficult to enter, the urethral wall is damaged if the urethra is forced to enter, in addition, a metal urethral probe in the patent is used for entering the urethra, but in the actual operation process, when the diseased part of the hyperplasia is blocked, the metal urethral probe cannot enter at all, if all the stents can be used for expanding the urethra, it is therefore necessary to progressively open the blocked urethra and then to gain a little access to the blocked urethra in order to gain further access to the bladder through the prostatic hyperplasia, and it is clear that the solution of this patent is useful for mild patients, but not for severe patients, where forced access would only cause greater harm to the patient.
