MOBILE C-ARM REDESIGN
|Project: ||Redesign and manufacture lift arm and brake systems for mobile orthopedic C-arm|
|Client:||Lunar Corporation (now GE Lunar)|
Lunar Corporation created a compact, mobile orthopedic x-ray system (ORCA) for use in operating rooms. After identifiying a need for increased stiffness and position-holding capability in the C-arm, Lunar contracted Sebring Design to redesign the lift arm and brake systems to meet the new specifications.
Lunar had completed an initial production run before changing the specifications. As a result, a challenge in this project was to incorporate as many as possible of the existing components into the new design.
Sebring Design performed diagnostic life tests on the C-arm motions to identify specific targets for redesign. All new components were modeled in SolidWorks. We redesigned the brakes for lift, vertical pivot, horizontal pivot, and C-rotation. After manufacturing and installing a retrofit lift arm and brakes, we performed final life tests and the improved assembly passed successfully.
