This study is a prospective, comparative trial designed to evaluate the cleaning effectiveness of a novel pulsed vacuum cleaning and disinfection device against a conventional vacuum ultrasonic cleaner for rigid endoscopic instruments. Key outcomes measured include cleaning time, cleaning quality (via visual, light source, and ATP inspection), protein residue levels, and instrument damage rate.
