Abstract

The invention discloses a double balloon positioning prostatic capsule expansion and prostatic capsule tissue splitting displacement catheter which comprises a catheter main body; a urinary catheterization cavity, a flushing cavity, a front balloon cavity and a rear balloon cavity are arranged in the catheter main body; the four cavities are provided with front end openings respectively; the front balloon cavity is formed in the rear parts of the front end openings of the urinary catheterization cavity and the flushing cavity; the rear balloon cavity is formed in the rear part of the front balloon cavity in parallel; the front end openings of the urinary catheterization cavity are two holes; the front end opening of the flushing cavity is a single hole; the length of the front balloon cavity is 38 cm; the outside diameter of the front balloon cavity and the rear balloon cavity are 3.2-3.9 cm when the front balloon cavity and the rear balloon cavity are filled up. The catheter is characterized in that the front balloon cavity and the rear balloon cavity are barrel-shaped after being filled up; the length of the front balloon cavity is equal to or larger than that of the rear balloon cavity; the outside diameter of the catheter main body is 0.6-0.8 cm. The catheter has the advantages that the requirement and selection of various hyperplastic prostate treatment can be met, especially the requirements of patients with apex of prostate exceeding verumontanum and external urethral sphincter. The catheter is made of TPU, and has the advantages of being high in pressure resistance, shapable, high in tightness, soft, smooth and transparent.

Description

technical field [0001] The invention relates to an improved catheter for the expansion of the capsule of the prostate and the dehiscence of the prostate tissue for positioning with double capsules. Background technique [0002] Existing technologies, such as utility model patent No. ZL201220707109.5, a dual-capsule positioning prostate capsule expansion catheter, including a catheter body (A), which is equipped with a catheterization cavity, a flushing cavity, and an anterior capsule cavity (B) , Posterior cystic cavity (C), the four cavities are respectively provided with front openings, the rear part of the front openings of the catheterization cavity and the irrigation cavity is the anterior cystic cavity (B), and the rear part of the anterior cystic cavity (B) The posterior capsule cavity (C) is arranged in parallel; the front opening (A1) of the catheterization cavity is two holes, and the front opening (A2) of the irrigation cavity is a single hole; the length of the c...
