Special catheter for patient with prostatic hyperplasia

Abstract

The invention provides a special catheter for a patient with prostatic hyperplasia, and relates to the technical field of a urology department. An inner pipe is arranged in an outer pipe, a second airinlet pipe, a supporting device and a rolling device are arranged on the outer pipe, the second air inlet pipe is arranged on the inner wall of the outer pipe, and the supporting device is arranged on the outer side surface of one end of the second air inlet pipe; a first air inlet pipe is arranged on the supporting device; the rolling device is arranged at the tip of the outer pipe at one end ofthe supporting device; the supporting device consists of at least two supporting bodies, a telescopic pipe, a fastening ring, a supporting inner wall and the first air inlet pipe, the fastening ringis arranged on the outer side surface of one end of the outer pipe, the supporting bodies and the supporting inner wall are arranged on the fastening ring, the telescopic pipe is arranged between thetwo supporting bodies, the telescopic pipe, the supporting bodies and the supporting inner wall commonly form a closed space, and the first air inlet pipe is arranged on the supporting bodies. The special catheter is reasonable and practical in structure and can be effectively inserted into a patient with the prostatic hyperplasia, so that the risk caused during a bladder puncture operation of thepatient is avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of urology, in particular to a special urinary catheter for patients with benign prostatic hyperplasia. 【Background technique】 [0002] It is well known that benign prostatic hyperplasia is a very common disease.

[0002] It is well known that benign prostatic hyperplasia is a very common disease. Prostatic hyperplasia will block the urethra, resulting in poor urination. When the patient is hospitalized, due to bed rest, it is necessary to use a catheter to assist the patient to urinate. However, in case of The problem comes when the patient with benign prostatic hyperplasia is hospitalized. It is difficult for the usual urinary catheter to enter the patient's body when the prostate is enlarged. In this case, it is difficult for even experienced surgical experts to insert the current urinary catheter into the patient's body during the operation, and finally they can only assist the patient's urination through bladder puncture. The operation will not only increase the patient's treatment cost, but also cause certain damage to the patient's body, and the patent number is: CN88219869.6, the application date is 1988.08.12, the patent name is: a prostatic urethral dilator, and its specific method The purpose of expanding the prostatic urethra is to expand the pressure-resistant balloon by inflating it. However, in practice, this method cannot well stretch the urethra at the hyperplasia of the prostate, and the urethra becomes curved due to the compression of the hyperplasia of the prostate. The pressure-resistant airbag in this patent is opened at one time, so it can only stretch the urethra at one point, and it is obviously unrealistic to stretch the entire urethra at the hyperplasia of the prostate, because it is difficult to enter The urethra at the hyperplasia of the prostate, if forcibly entered, will also destroy the urethral wall. In addition, the metal urethral probe in this patent is used to enter the urethra, but in the actual operation process, when the diseased part of the hyperplasia is blocked In some cases, the metal urethral probe cannot get in at all. If it can go in, then all the stents can be used to expand the urethra. Therefore, it is necessary to gradually open the urethra at the blockage, and then enter the urethra at the blockage bit by bit, so that Only through the prostatic hyperplasia can the bladder be further reached, and obviously the solution of this patent is useful for mild patients, but it cannot be done for patients with severe benign prostatic hyperplasia, forcible entry will only bring greater harm to the patient
