Disposable flexible ureteroscope with dual working channels

Abstract

This invention relates to a disposable flexible ureteroscope with dual working channels. It comprises a housing having an installation part and a gripping part, and internally forming a first delivery channel and a second delivery channel. The gripping part is located at the bottom of the installation part and extends towards the rear end of the installation part. The installation part has a catheter extending towards the front end. The catheter is internally divided into a first working channel connecting the first delivery channel and a second working channel connecting the second delivery channel. The installation part has an irrigation tube and a connecting tube connecting the first delivery channel, and the gripping part has a discharge tube connecting the second delivery channel. Thus, the catheter has dual working channels, which can perform irrigation and aspiration operations in different working channels, or can perform irrigation and aspiration operations through the first working channel when the second working channel is blocked, providing patients with an extra layer of protection.
