Multicavity three-sac prostate capsule dilating and tissue cracking shifting catheter

Abstract

The invention discloses a multicavity three-sac prostate capsule dilating and tissue cracking shifting catheter which comprises a catheter main body, wherein a catheterization cavity, a front sac cavity, a back sac cavity, an inner sac cavity and a front flushing cavity are arranged in the catheter main body; a front flushing opening and a catheterization port communicating to the front flushing cavity and the catheterization cavity are separately formed in the front end of the catheter main body; a front sac communicating to the front sac cavity is arranged on the back part of the catheterization port; a back sac communicating to the back sac cavity is arranged on the back part of the front sac; and an inner sac communicating to the inner sac cavity is arranged at the front end in the front sac. The catheter can be also effectively fixed to the affected part while meeting an operating demand of dilating the membranous urethra and the prostate urethra in steps or in turns, so that traction positioning and hemostasis by compression of the catheter are achieved. According to the catheter flushed by a lot of water flows, caused wounds are minimal, patients have small pain, and the cure rate can be increased effectively and the postoperative recovery is accelerated.

Description

technical field [0001] The invention relates to a multi-cavity three-capsule positioning catheter for prostate capsule expansion and tissue fissure displacement, which belongs to the technical field of medical devices. Background technique [0002] In the process of treating male benign prostatic hyperplasia, due to the differences in the size and shape of the male prostate, especially in some patients, the apex of the prostate extends to the distal end of the spermatorrhea, the existing product structure cannot meet the needs of various hyperplastic prostate treatments And options, especially for patients whose apex of the prostate exceeds the Fus and the external urethral sphincter cannot be met. [0003] The application number is CN201220708881.9, and the title is a patent for invention of a peeping positioning prostate capsule expansion catheter, and the application number is CN201220707109.5, and the name is a patent for invention of a double-vessel positioning prostate...

AI Technical Summary

Problems solved by technology

In the actual use process, the catheter with this structure has the following problems: the actual length of the membranous urethra is about 1-2 cm, which is much shorter than the length of the prostate. The filling volume needs to be relatively large, and the anterior capsule in the above patent is mainly used to pull and position the catheter. Although the anterior capsule also has the function of dilating, due to its small length and size, the actual expansion effect is not ideal

The prostate expansion catheter of this patent can still only expand the prostate, but cannot meet the expansion needs of the membranous urethra, and it is easy to slide into the bladder and has no expansion effect on the membranous portion
