Beside the main channel for ureteroscope and liquid infusion, Y-Shape sheath adds a bypass channel to reduce the visual interference and facilitate the stone discharging, together with the external negative pressure suction mechanism.
Working principle: In urological surgery, the access guide sheath is used in combination with the dilators. After entering the urinary tract under the guidance of B-ultrasound or X-ray, the dilator is withdrawn and the guide sheath is left in place to establish and maintain the passage for endoscope and other instruments to enter the urinary tract.
Scope of application: Disposable ureteral access sheath is used to establish tract/passage for endoscope and other instruments to enter the urinary tract during urological surgery.
Applicable population: It is suitable for patients who need to establish tract/passage for endoscope and other instruments to enter the urinary tract.
