Abstract

The invention discloses a urethral dilator used for men. The urethral dilator comprises a handle and a sleeve, wherein the sleeve is fixed at the front end of the handle; a first passage and a second passage which are mutually communicated are arranged in the handle; a rotating switch is arranged on the second passage. The urethral dilator is structurally characterized by being also provided with a catheter; one end of the catheter is fixed in the handle through the sleeve; the other end of the catheter is provided with a ball bag; a ball bag passage and a urethral passage which are mutually independent are arranged inside the catheter; one end of the ball bag passage communicates with the second passage; the other end of the ball bag passage communicates with the inside of the ball bag; one end of the urethral passage communicates with the first passage; the other end of the urethral passage communicates with the outside. The urethral dilator has the advantages that the structure design is reasonable; the use is convenient; the effective dilation and flushing is realized; minimally invasive and non-injury effects are achieved.

Description

technical field [0001] The invention relates to a urethral dilator for males. Background technique [0002] The urethral dilator used by men is a commonly used medical device in urological surgery. It is used in the examination and diagnosis of male urethral diseases and surgical treatment of urethral injury caused by trauma. Its function is to expand the narrow urethra and has a wide range of applications. [0003] Traditional urethral dilators are simple in structure and low in cost, and will cause damage to the urethra during expansion, so the technical requirements for doctors are relatively high. As the position and size of urethral stricture vary greatly, if the doctor is inexperienced, it is easy to form a false tract during the expansion process, and even expand to the rectum, resulting in serious surgical complications, resulting in long operation time and low operation quality. as a result of. Contents of the invention [0004] The technical problem to be solve...
