Description
Ureteral Negative Pressure Access Sheath is a specialized urological device designed for efficient and safe minimally invasive surgery. It features a flexible seamless tip with a smooth long cone shape, enabling soft insertion and seamless transition between the inner core and outer sheath, allowing one-step gradual dilation during placement. The sheath tip can be bent to any angle, ensuring accurate and efficient pre-dilatation and device positioning.
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 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.
A dedicated negative pressure suction opening allows manual adjustment of suction pressure to clear the surgical field and improve visualization. Clear surface scales enable precise depth control, supporting accurate placement in clinical procedures.
