Novel prostate dilation catheter

Abstract

The invention provides a novel prostate dilation catheter, which comprises a main tube, wherein a urinary catheterization cavity, an internal capsule cavity, an external capsule cavity and a flushing cavity are formed inside the main tube; a composite bar-like high pressure water capsule is arranged in the fronts of the outlet of the urinary catheterization cavity and the outlet of the flushing cavity; the composite bar-like high pressure water capsule comprises an internal capsule and an external capsule; the internal capsule is arranged at the front end of the interior of the outer capsule; and the front ends of the internal capsule cavity and the external capsule cavity are respectively formed with openings inside the internal capsule and the external capsule. By virtue of the structure, the catheter can automatically move inwards urinary bladder after bladder neck is dilated, so as to relieve stress on external sphincter to prevent the occurrence of urinary incontinence; and in addition, the catheter disclosed by the invention is more conducive to preoperative localization and postoperative fixation, so that the catheter is prevented from slipping after surgical decompression.

Description

technical field [0001] The invention relates to a novel prostatic fissure expansion catheter, in particular to a composite rod-shaped water bladder dilatation prostate catheter in which the inner capsule is located at the front end of the outer capsule. Background technique [0002] Prostatic hyperplasia (BPH) is a common benign lesion in elderly men. The incidence rate 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 ...

AI Technical Summary

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

[0007] For the second type of dilated prostate catheter, because the outer capsule is columnar after expansion, it is not conducive to sliding into the bladder during operation to avoid long-term compression of the external sphincter, and it is also not conducive to pulling and compressing hemostasis after surgery; in addition, the inner capsule Located at the back end of the external capsule, it is not conducive to preoperative positioning and postoperative fixation of the catheter, and there may be a risk of slipping
