The clinical advantage of disposable ureteral guidance sheath

Its clinical advantages are mainly reflected in the following aspects:

(1) reduce the risk of surgery and reduce surgical complications.The use of negative pressure suction during ureteroscopic holmium laser lithotripsy can effectively reduce the intrapelvic/ureteral pressure and reduce the increased intrapelvic/ureteral pressure

Related complications.

(2) to ensure clear surgical vision and improve the efficiency of gravel.By adjusting the perfusion flow, pressure and negative pressure, it can effectively suck out the blood, pus and gravel powder in the renal collecting system, keep the field of vision clear under the mirror, make continuous gravel possible, improve the surgical efficiency and enhance the surgical safety.

(3) stone removal should be carried out at the same time to improve stone clearance rate.By adjusting the appropriate negative pressure attraction, the powdered stone fragments were rapidly attracted out of the body through the space between the sheath tube and the ureteral (soft) mirror, achieving the clinical effects of side lithotripsy, side lithotripsy and side lithotripsy, significantly improving the stone removal rate, and avoiding the second operation.

(4) type II product is added on the scabbard tube with size marking (no marking for the conventional scabbard) to facilitate clinical confirmation of the depth of the scabbard tube insertion and the location of stone lesions.
