ScopeAssist is a modular endoscope control attachment designed to reduce the physical strain associated with prolonged endoscopic procedures. Conventional endoscopes require repeated thumb movement to operate the angulation wheels while the clinician simultaneously grips, stabilises and rotates the scope, which can contribute to hand and wrist fatigue. ScopeAssist motorises the existing angulation controls and replaces repetitive wheel manipulation with an intuitive thumbstick interface, allowing the clinician to control tip movement while retaining the familiar endoscope, existing clinical workflow and direct control of the procedure. The project explores how a low-disruption, retrofit approach could improve ergonomics without requiring the replacement of current endoscopy systems.
