Visual eccentric prostate dilation catheter

Abstract

The invention relates to a prostate dilation catheter, in particular to a visual eccentric prostate dilation catheter. The visual eccentric prostate dilation catheter is characterized in that the front end portion of a dilation catheter body as a main body is provided with a urinary catheterization opening, and a urinary catheterization cavity is formed in the dilation catheter body; the visual eccentric prostate dilation catheter further comprises a composite dilation bag which comprises an external dilation bag body and an internal dilation bag body, and an external bag communication cavityand an internal bag communication cavity are formed in the dilation catheter body. Two openings are formed in the rear end of the internal bag communication cavity, one, as a water injection opening,of the end openings is used for injecting water, and the other end opening as a mirror opening is used for allowing an observation mirror or a line to pass. The visual eccentric prostate dilation catheter can provide a visual operation space in the dilation process, and the safety of a surgery is improved.

Description

technical field [0001] The invention relates to a prostate dilation catheter, in particular to a visualized eccentric prostate dilation catheter. Background technique [0002] Transurethral dilatation, also known as prostatic urethra and membranous urethral dilation, is a relatively advanced treatment technique for benign prostatic hyperplasia. It has a high safety factor and is increasingly becoming an effective method for patients with benign prostatic hyperplasia to solve urination difficulties. [0003] With the rapid development of medical technology, all kinds of medical devices have entered the "visualization era", and the most important surgical instrument in prostate dilation, the prostate dilation catheter, has also appeared in the trend of "visualization", such as A Chinese patent number is 201710560321.0, a patent named "Visually Positioning Prostate Dilation Catheter", which discloses a visualized dilation catheter, which uses a flexible endoscope to observe th...

Problems solved by technology

[0004] However, in order to further improve the convenience and safety of the operation, we are not satisfied with the precise position of the catheter. Due to the differences in the growth patterns of benign prostatic hyperplasia between individuals, the wall of the prostatic tissue after hyperplasia is different. There is a huge difference in the thickness of the dilated sac, and the surgical operation for dilation is currently performed by the experience of the medical staff themselves, and the dilated surgical site cannot be observed, so it is impossible to properly grasp the pressure of the dilated sac; The blood supply is rich, but the existing expansion catheter cannot be visualized during the expansion process, so it is difficult to control the expansion process, and the operation risk is high

[0005] It can be seen that although similar prior art solutions solve the problem of accurately placing the expansion capsule into the position of the prostate, they cannot achieve "visualization" during the expansion process. Therefore, in the field of prostate expansion, the current prior art There is still a big gap from the real "visual"
