Visual eccentric prostate dilation catheter

Abstract

The invention relates to a prostate dilation catheter, and in particular relates to a visual eccentric prostate dilation catheter. A main body of the visual eccentric prostate dilation catheter is thedilation catheter; a fixing bag capable of being clamped in the bladder and a dilation bag used for dilating the urethra sleeve the periphery of the dilation catheter in the sequence from front to back, the dilation bag is made of a transparent material, a catheter body of the dilation catheter penetrates through the dilation bag, and the position, penetrating through the dilation bag, of the catheter body of the dilation catheter deviates from the central area of the dilation bag; a urethral catheterization cavity used for urethral catheterization, an observing pipeline used for passing through of an observing mirror or a line, and a water injecting pipeline used for injecting water for the fixing bag are arranged in the dilation catheter; the front end of the urethral catheterization cavity communicates with the outside through urethral catheterization openings, and the rear end of the urethral catheterization cavity communicates with the outside; the front end of the observing pipeline communicates with the inner cavity of the dilation bag, and the rear end of the observing pipeline communicates with the outside; and the front end of the water injecting pipeline communicates with the inner cavity of the fixing bag, and the rear end of the water injecting pipeline communicates with the outside. For the visual eccentric prostate dilation catheter, the visual operation space can be provided during the dilation process, and thus the safety of the 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 water sac dilation, also known as prostatic urethra and membranous urethral dilation, is a relatively advanced treatment technology for benign prostatic hyperplasia, and it is also the only surgery that preserves the original organs among many prostate surgeries, with minimal trauma and short operation time , with a high safety factor, has increasingly become an effective method for patients with benign prostatic hyperplasia to solve dysuria. [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 enlargement surgery - prostate expansion catheter, there is also a "visualization" trend, such as A Chinese patent No. 201710560321.0, titled "Visual Positioning Prostate...

AI Technical Summary

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"
