Model and specification: 10Fr17cm, 10Fr28cm, 10Fr35cm, 10Fr42cm, 10Fr45cm, 10Fr55cm, 10Fr55cm, 12Fr17cm, 12Fr28cm, 12Fr35cm, 12Fr42cm, 12Fr45cm, 12Fr55cm, 12Fr55cm, 14Fr1 7cm, 14Fr28cm, 14Fr35cm, 14Fr42cm, 14Fr45cm, 14Fr55cm, 14Fr55cm

Composition and structure: The disposable ureteral negative pressure introducer sheath consists of a sheath tube and a dilator. The sheath is composed of nylon, PTFE and stainless steel; the Y-joint is made of polycarbonate; the sealing cap is made of silicone

Scope of application: Treatment of kidney stones and ureteral stones under ureteroscope. To establish a channel during the operation so that the negative pressure part can effectively adjust the suction pressure, and the stone crushing and stone removal are can be executed simultaneously, effectively improving the clearance rate, preventing stone reflux, reducing the intracavity pressure during the operation, and decreasing surgical complications。

Features:

① Reduce intracavitary pressure and reduce surgical complications

② The surgical field of view is clear, which improves the efficiency of lithotripsy. The blood, pus and gravel powder in the renal collecting system can be effectively sucked out by adjusting the perfusion flow, pressure and negative pressure; the vision under the microscope is kept clear, which realizes continuous lithotripsy, improving the operation efficiency and the safety of the operation

③ Lithotripsy and stone cleaning are carried out at the same time to improve the efficiency of stone cleaning.By adjusting the appropriate negative pressure suction, the powdered stone fragments can be quickly sucked out of the body through the gap between the sheath tube and the ureter (soft) mirror, which realizes the clinical effect of stone crushing, suction and stone removal, markedly improving the stone removal rate and avoiding secondary surgery

④The product adds a size mark on the sheath, which is convenient for confirming the insertion depth of the sheath and the lesion site of the stone clinically
