Problems solved by technology

[0003] However, at present, there is a common phenomenon in the prostate expansion catheter that after the use of the prostate expansion catheter, a large amount of blood will be stained, and the patient after use is prone to thrombus; In the natural state, the size and tolerance are quite different, so it is easy to have too much prostate tear or insufficient prostate tear during operation, which not only reduces the effect of surgery, but also may cause damage due to excessive expansion of the non-prostatic urethra. Injury to urinary continence and urethra

Abstract

The invention relates to the field of medical equipment for dilatation of the prostate, in particular to a novel catheter for dilation of the prostate. A novel prostatic fissure catheter is provided with a catheterization cavity, a flushing cavity, and a high-pressure water bladder cavity. Compared with the catheters currently on the market, the prostate expansion catheter described in the present invention is more accurate and convenient in positioning, and can be kept fixed after the prostate is expanded to ensure the expansion effect, play the role of compression and hemostasis, and relieve the compression of the external sphincter , will not excessively damage the external sphincter, and prevent urinary incontinence and hemorrhage; in addition, the catheter of the present invention can effectively avoid blood coagulation during the operation due to the addition of foreign materials, resulting in the danger of thrombus, and the water bladder can be expanded freely and naturally The tolerance of the size in the state is not large, so that the pain of the patient is reduced during the operation.

Description

technical field [0001] The invention belongs to the field of medical equipment for prostate dilation, and more specifically, the invention relates to a novel prostate dilation catheter. Background technique [0002] Prostatic hyperplasia is a common disease in middle-aged and elderly men. The so-called benign prostatic hyperplasia is mainly due to the hyperplasia of the prostate tissue, resulting in an increase in its volume, which in turn squeezes the surrounding organs, resulting in a smaller and narrower urinary tract, resulting in dysuria, frequent urination, Prolonged urination and other symptoms. The traditional treatment method is to cut the prostate tissue, but the operation is a big blow to the patient, and the elderly's physical and psychological tolerance to the operation is poor, so they are unwilling to accept the operation. At present, the more advanced treatment method is prostate expansion surgery. This treatment operation is to insert the prostate expansion...
