Key Components & Features

1. Puncture Needle

• Features a frosted tip and air slots in the inner core, delivering an excellent dual contrast effect for clear visualization during puncture, enabling accurate hepatic access.

2. Guide Wire

• Constructed with a Nitinol core for robust structural support and maneuverability.
• Equipped with a hydrophilic-coated head end, significantly reducing insertion resistance and ensuring smooth navigation through hepatic anatomy.

3. Dilators

• Manufactured from medical polyethylene material with moderate stiffness, balancing flexibility and pushability for controlled dilation of the transhepatic tract.

4. Peelable Sheath

• Offers negative/non-negative pressure options to accommodate diverse clinical needs.
• Boasts a seamless transition at the sheath tip, facilitating smooth insertion and minimizing trauma during placement.

5. Drainage Tube

• A straight single-lumen silicone drain with a large internal lumen, enabling unobstructed and efficient drainage of hepatic fluids.
