Visual urethra dilatation kit

Abstract

The invention discloses a visual urethral dilation kit, which comprises a urethroscope, a guide wire, a balloon, a guide sheath, a balloon pressurizer, a urethral dilator and a pusher, wherein the balloon is provided with the guide wire; a channel allowing the guide wire to penetrate through is arranged in the urethroscope; the balloon pressurizer and the balloon with the guide wire jointly form a balloon dilator; the balloon pressurizer is connected to the rear end of the guide wire of the balloon and communicates with the balloon through a pressurizing hole in the guide wire; the diameter of the guide sheath is larger than that of the guide wire; the urethral dilator is in sleeving at the front end of the guide sheath; and the pusher is connected to the rear end of the guide sheath and has the same diameter with the guide sheath. According to the visual urethral dilation kit, the modes of balloon dilation and urethral dilator implantation are adopted, the visual technology is combined, and the purposes of accurately, effectively and continuously dilating the urethra and protecting the bladder and kidney functions are achieved.
