Split Overtube Prevents Loop Formation During Colonoscopy

USPTO published patent application US20260083313A1 for a split overtube device designed to prevent loop formation during colonoscopy. The device features a longitudinal split allowing placement over an endoscope shaft during an ongoing procedure. Invented by Rafal Sadurski, the overtube uses segmented oval openings and a fastening mechanism to create a semi-rigid conduit that translates axial force into forward endoscope movement without dangerous loop formation.
