“Copper” Disposable Ureteral Access Sheath
Structure and Composition
The disposable ureteral access sheath consists of a dilator, sheath, and guide wire.
The dilator of the conventional ureteral access sheath consists of a tube body, base, and locking clip, while the sheath consists of a tube body and base (with suture holes).
The dilator of the vacuum ureteral access sheath consists of a tube body and locking connector, while the sheath consists of a tube body, Y-shaped sheath connector, and sealing cap. The guide wire is composed of a nitinol alloy core with a PTFE-coated surface, and the guide wire tip is straight.
Application
It is only used in urological ureteroscopic surgery as a channel for instrument passage.
Product Features:
- The unique locking device on the base of the dilator securely locks the dilator onto the access sheath, allowing for simultaneous advancement of the sheath and dilator.
- The reinforced wire structure of the sheath is resistant to compression and kinking, and the smooth outer surfaces of the access sheath and dilator facilitate easier insertion.
- The tip of the dilator is smooth and conical, allowing for gradual dilation with minimal trauma. The tube body is radiopaque, providing excellent imaging visibility.
- The PTFE inner layer of the sheath facilitates smooth passage and retrieval of instruments. Its thin-wall structure maximizes the inner lumen while keeping the outer diameter as small as possible.
- The straight tube of the vacuum access sheath’s connector serves as a passage for instruments, while the angled tube allows fluid drainage or can be used as a vacuum suction channel. The angled tube at the Y-shaped connector of the sheath allows fluid drainage or can be connected to a vacuum suction device.
- The flexible and bendable distal end of the sheath allows for easy entry into the renal pelvis and calyces.
