Abstract

The invention discloses a urethral dilator. The urethral dilator comprises a conduit, a first vertical through hole is formed in the conduit, dilatation arms are symmetrically hinged to the inner walls of the two sides of the top of the first vertical through hole, and first springs are arranged between the inner walls of the dilatation arms and the first vertical through hole; the first verticalthrough hole comprises a front hole section and a back hole section, air channels, alcohol channels, air feeding mechanisms and alcohol feeding mechanisms are arranged on the two sides of the front hole section, and air generating mechanisms connected with the air feeding mechanisms are arranged on the two sides of the back hole section; the urethral dilator also comprises a linking mechanism linked with the air feeding mechanisms and the alcohol feeding mechanisms. By means of the urethral dilator, the problems that a present urethral dilator is poor in dilation effect and fussy in operationare mainly solved.

Description

technical field [0001] The present invention relates to a device for delivering a medium into or onto a human body. Background technique [0002] With the development of endovascular technology in urology, the transurethral approach has become the most important natural channel for urology diagnosis and treatment. Dilation of a narrow urethra with a urethral dilator is the most common approach when endoscopic access to the posterior urethra and bladder is not possible during endoscopic procedures (eg, transurethral resection of the prostate, transurethral resection of bladder tumors). When dilating the urethra, the urologist inserts a traditional urethral dilator into the urethra and bladder according to the anatomical structure of the urethra and operating experience. For male urethras with narrow and abnormal angles, urethral mucosal false passages, avulsions, and perforations are prone to damage, causing Complications such as urinary extravasation and long-term urethral ...
