Abstract

The invention discloses a urethral sheath of an ureteroscope. The urethral sheath comprises an insertion part, a urethral sheath wall, a ureteroscope intubation tube, a compressible telescopic tube, an inflation module and a pressure measurement module; the insertion part is fixed at the front end of the urethra sheath wall; one end of the compressible telescopic tube is connected with the rear end of the urethra sheath wall, and the other end is connected with the ureteroscope intubation tube; the ureteroscope intubation tube is used for inserting a ureteroscope from the rear end of the wholeurethral sheath; a pressure measuring module for monitoring the pressure in the bladder is arranged on the insertion part; and the inflation module is arranged on the outer wall of the front end of the urethral sheath wall and used for flexibly fixing the urethral sheath after inflation expansion. The pressure measuring module can detect the pressure in the bladder, the urethral sheath can be prevented from slipping to injure the urethra through the inflation module, the success rate of an operation can be effectively increased, and the risk of serious surgical complications is reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a urethral sheath for a ureteroscope. Background technique [0002] Urinary calculus is a common disease in urology. In recent years, the incidence of urinary stones in my country has been increasing, and it is one of the three high-incidence areas of stones in the world. At present, the prevalence of kidney stones in Chinese adults is 5.8%, and there are about 61 million kidney stone patients, including about 34.7 million men and 26.5 million women. With the development of endourology, flexible ureteroscope has been widely used by urologists as the main method for the treatment of kidney stones because of its minimally invasive, safe and effective features. Ureteroscopic lithotripsy needs to pass through the urethra during the operation, and it needs to be pushed and pulled back and forth during the operation, which can easily cause urethral injury, infection, and stricture....
