This 8 mm inner diameter x 5 cm PassPort button cannula is a specialized soft orthopedic portal component engineered from low-friction medical silicone. Its flexible double-flange design collapses easily for port placement, creating a stable, low-profile working bridge that prevents soft tissue fluid leakage during arthroscopy workflows. Delivered sterile, it shields fragile capsular margins from instrument friction and resists cannula displacement bugs.
