Needle in needle system is a twin needle, with inner tube made from steel and screw cap is connected by inner needle.

Product characteristics

1. Needle in needle design meets needs of both fine needle aspiration of cells and tissues from paracentesis and suction.

2. Lumen is unobstructed for suction, which increases the sampling quantity.

Operational method:

2. Withdraw the puncture needle tube under direct vision of endoscope, and the assistant connects inner tube cap and outer tube cap to fix them.
