ScopeAssist
FOCUS
Clinical research / Mechanism design / Prototyping
A removable powered-assist attachment that explores a more intuitive way to steer existing endoscopes.
01 / THE CHALLENGE
A familiar tool. A demanding interaction.
Endoscope steering asks clinicians to stabilise a handle while repeatedly manipulating two angulation wheels. ScopeAssist investigates how powered assistance could support that interaction while preserving access to familiar controls and retaining clinician authority.
02 / RESEARCH & PROCESS
Research where the work happens.
A day observing 8 procedures at Glasgow Royal Infirmary, hands-on exploration with an endoscopy simulator, and discussions with 7 gastroenterologists and researchers shaped the brief. Reach, repeated thumb movement and coordination emerged as key concerns. The design direction became an attachment for existing equipment, rather than an entirely new endoscope.
03 / DESIGN DECISIONS
Prove the mechanism, then refine the form.
An initial ball-chain mechanism demonstrated that the existing angulation wheels could be motorised externally to steer the distal tip. A second prototype brought the mechanism into a more integrated housing. A thumbstick was selected as the intended two-axis input, with the electronics and battery architecture still to be fully integrated.
04 / OUTCOME & REFLECTION
A validated direction. A clear path forward.
ScopeAssist demonstrated the potential of powered endoscope angulation through a compact, intuitive assistive system designed around existing clinical workflows. The concept received highly positive feedback from clinicians and faculty, particularly for its potential to reduce thumb strain, improve comfort and support more controlled endoscope manipulation during prolonged procedures.
​
ScopeAssist ultimately demonstrated how a focused mechanical intervention could meaningfully enhance a long-established medical interface while retaining the familiarity and control clinicians already rely on.
