The flexible ureteroscope front-end bendable negative pressure sheath technology is mainly used in combination with flexible ureteroscopes for minimally invasive treatment of kidney stones or upper urinary tract diseases.Its core functions include continuously aspirating stone fragments, blood or irrigation fluid during surgery through a negative pressure suction system, maintaining a clear surgical field, reducing intrarenal pressure, lowering the risk of infection, and improving the efficiency of stone fragment removal.The flexible ureteroscope front-end bendable negative pressure sheath technology is mainly used in combination with flexible ureteroscopes for minimally invasive treatment of kidney stones or upper urinary tract diseases.Its core functions include continuously aspirating stone fragments, blood or irrigation fluid during surgery through a negative pressure suction system, maintaining a clear surgical field, reducing intrarenal pressure, lowering the risk of infection, and improving the efficiency of stone fragment removal.The flexible ureteroscope front-end bendable negative pressure sheath technology is mainly used in combination with flexible ureteroscopes for minimally invasive treatment of kidney stones or upper urinary tract diseases.Its core functions include continuously aspirating stone fragments, blood or irrigation fluid during surgery through a negative pressure suction system, maintaining a clear surgical field, reducing intrarenal pressure, lowering the risk of infection, and improving the efficiency of stone fragment removal.
