Problems solved by technology

However, due to the small diameter of the catheter itself, multiple chambers have been set up inside, and the space is limited, which has certain space limitations for setting up the camera
At the same time, when the catheter enters the human body, if the patient bleeds a lot, blood clots can easily blur the camera, resulting in unclear vision and obstacles to visualization

Abstract

The invention discloses a visual membrane and prostatic part urethra dilation catheter which comprises a catheter body, a urethral catheterization cavity, an irrigation cavity, a front balloon cavity and a rear balloon cavity. The urethral catheterization cavity, the irrigation cavity, the front balloon cavity and the rear balloon cavity are arranged in the catheter body, one end of the urethral catheterization cavity is connected to the head of the catheter body and provided with at least two holes, and the other end of the urethral catheterization cavity is led out from the tail of the catheter body and connected with a water injection tube. The visual membrane and prostatic part urethra dilation catheter is characterized by further comprising a visual probe for observing the path of the catheter body entering a body, the visual probe enters the catheter body through the urethral catheterization cavity and is arranged in one hole in one end of the urethral catheterization cavity, and a signal wire of the visual probe is led out from the other end of the urethral catheterization cavity and connected onto a control computer. The internal space of the dilation catheter is reasonably used, the visual probe is arranged in the urethral catheterization cavity, and the problems of deficiency of dilation catheter space and incapability of setting the visual probe are solved.

Description

technical field [0001] The invention relates to a catheter for dilating the urethra with visible membranous part and prostatic part. Background technique [0002] The inventor has disclosed the expansion catheter structure of the prostate capsule and prostate tissue in several Chinese patent documents such as CN 202982896 U and CN 204932549 U. This expansion catheter usually includes a catheter body and a catheterization cavity, a flushing cavity, an anterior capsule cavity and a posterior capsule cavity arranged on the catheter body. After injecting water into the anterior and posterior cystic cavities, the anterior and posterior cystic cavities are filled and become barrel-shaped to achieve the effect of expanding the prostate tissue. The expansion catheter is used in the treatment of prostatic tissue site expansion, retains the original organ, retains the original function, has minimal trauma, and has a high safety factor. [0003] However, due to the small diameter of ...
