Disposable ureteral guide sheath (abbreviation: ureteral guide sheath, flexible scope sheath)
Scope of application: For urological surgery, to establish a channel for endoscopes and other instruments to enter the urinary tract.
1. The dilation tube has good flexibility, and the smooth tapered tip seamlessly transitions with the sheath, which is easy to expand;
2. The sheath tube is designed and composed of three layers of polyamide elastomer (PEBAX) on the outer wall, 304 stainless steel in the middle layer, and polytetrafluoroethylene (PTFE) on the inner wall. The outer wall of polyamide elastomer makes the sheath tube have excellent toughness and chemical resistance high-strength metal spring reinforcement structure, which improves the radial support force and bending resistance of the sheath, and the PTFE inner structure greatly reduces the resistance of other instruments passing through the sheath, which can effectively protect surgical instruments during operation. Smooth operation in the sheath;
3. The hydrophilic coating on the surface of the sheath becomes super slippery after contacting saline/urine, reducing resistance and reducing urinary tract damage;
4. Reduce the damage to the ureter wall during the repeated exchange of instruments, and protect other precision instruments such as ureteroscopes from damage.
