A catheter for use in patients with urethral malformations and strictures

Abstract

The present invention discloses a catheter for use in patients with urethral deformities and strictures, comprising a catheter. The front end of the catheter is equipped with a guide tube, while the rear end features an irrigation tube, a fixation tube, and a drainage tube. The catheter, irrigation tube, fixation tube, and drainage tube are integrally formed. The fixation tube is connected to a fixation connector. The guide tube is provided with a first side hole, while the catheter features a balloon on its outer peripheral wall and a second side hole. This invention eliminates the need for guidewire assistance, making it more suitable for patients with urethral malformations and strictures. It helps reduce tissue damage, facilitates faster recovery, and features a more rational design that simplifies manufacturing and installation.
