Each THORACOPORT™ 5.5 mm, 10.5 mm, 11.5 mm and 15 mm single use trocar consists of a blunt-tipped obturator and a threaded sleeve with a shroud at its proximal end to protect against foreign materials entering the chest cavity, and for instrument stabilization.
Once inserted into a free space in the chest cavity, the threaded sleeve is turned clockwise until securely seated in the tissue.
The threaded sleeve will grip tissue to reduce slippage during instrument manipulation.
