Description
Ureteral Access Sheath is a specialized urological device designed to establish a safe surgical channel for flexible ureteroscopy and ureterolithotomy, primarily used in the treatment of kidney stones.
It features a humanized funnel handle design that enables one-hand operation for easy locking of the dilator and cannula, improving clinical efficiency. The flexible seamless tip has a smooth long cone shape, allowing soft insertion and seamless transition between the inner core and outer sheath, enabling one-step gradual dilation during placement.
Constructed with a high-strength metal spring reinforced structure, it delivers enhanced radial support and bending resistance, maintaining structural integrity during manipulation. The inner layer is made of PTFE material, providing a smooth, ultra-thin wall cavity for seamless device insertion and removal. The surface of the dilator and sheath is coated with a hydrophilic layer, reducing friction for smoother insertion, while clear surface scales enable precise depth control.
