Prostate dilation catheter provided with front opening

Abstract

The invention provides a prostate dilation catheter provided with a front opening. The prostate dilation catheter comprises a main catheter body, an inner bag and an outer bag, wherein a urine guide cavity, a washing cavity, an inner bag cavity and an outer bag cavity are arranged in the main catheter body, the inner bag is positioned inside the outer bag, the tail end of the inner bag and the tail end of the outer bag are arranged at an interval, an opening is formed in the front end surface of the main catheter body, the urine guide cavity is connected with the opening, a locating bulge is arranged on the main catheter body, and the outer bag is positioned between the locating bulge and the opening. The front opening of the urine guide cavity is arranged on the front end surface of the main catheter body, guide wires or a catheter insertion aider can be inserted into the urine guide cavity, so that the insertion position of the main catheter body can be accurately acquired, and meanwhile, by combining with the arrangement of the locating bulge, the locating of the prostate dilation catheter is accurate, convenient and efficient. In addition, the tail end of the inner bag and the tail end of the outer bag are arranged at the interval, so that the locating effect can be further achieved.

Description

technical field [0001] The invention relates to the field of medical equipment for dilatation of the prostate, in particular to a catheter for dilation of the prostate with a front opening. Background technique [0002] Prostatic hyperplasia (BPH) is a common benign lesion in elderly men. The incidence rate of patients over 60 years old accounts for 65%, and 25% of patients have clinical symptoms and need medical or surgical treatment. The effect of traditional transvesical prostatectomy or electric resection and laser surgery is certain, but the surgery has a greater impact on patients, and the elderly have relatively poor physical and psychological tolerance for surgery, so many elderly patients are afraid of surgery . Long-term maintenance by catheterization, or even suprapubic cystostomy to solve dysuria. The quality of life is extremely poor. Using posterior urethral dilatation to treat benign prostatic hyperplasia is a method that the medical community should pay a...

Problems solved by technology

[0006] For the first type of prostatic dilatation catheter, since the outer capsule is located in the bladder, when the internal pressure is inflated, the internal slip is not easy to control, and the expansion effect is unstable

For the second type of prostate dilation catheter, due to the addition of a positioning convex, it is convenient to locate the catheter during the operation, but due to the different weights of the patients, for obese patients, the doctor can not be better during the operation. Sensing the positioning convex, which makes the positioning of the catheter difficult
