Urological Sheath (Bendable Ureteral Access Sheath & Ureteral Introducer Sheath)

Product Application Widely used in minimally invasive urological interventional procedures such as ureteroscopy and percutaneous nephrolithotomy to establish surgical access channels and guide endoscopes and instruments to lesion sites in the urinary tract. The adjustable bend sheath allows flexible angle adjustment to adapt to complex urinary tract anatomy, while the ureteral introducer sheath enables smooth insertion and reduces surgical trauma to the urinary tract. Material & Specifications Sheath inner diameters: 9Fr, 10Fr, 11Fr, 12Fr, 13Fr, 14Fr, 16Fr, 18Fr, 20Fr, 22Fr, 24Fr, 26Fr, etc. A complete range of specifications meets the needs of various surgical scenarios. The inner layer of the sheath is PTFE-treated with a multi-layer composite structure; the spring-reinforced shaft prevents kinking. The hydrophilic coating on the outer surface ensures smoother insertion. The dilator is made of modified imported materials with good elasticity and a soft, smooth, non-rigid tip to reduce tissue damage during insertion. The sheath features finely chamfered edges without sharp corners, providing a smooth transition with the dilator. Core Advantages Dual-material technology balances flexibility and rigidity for smooth, unobstructed insertion. The adjustable bend design improves surgical flexibility and reduces operational difficulty. The ultra-smooth coating effectively minimizes urinary tract mucosal injury and lowers the risk of postoperative infection. Lonyi’s standardized production process ensures stable batch quality. As China’s first OEM manufacturer of urological sheaths, we have achieved large-scale production with an annual output exceeding 500,000 units. The products comply with global clinical standards for urological surgery and are ideal supporting consumables for minimally invasive urological procedures.
