Hip Knee Navigation
Many patients take hip and knee replacement surgery for granted, but achieving the accuracy necessary for a proper joint fit that lasts for years isn't easy. Computer-aided navigation systems like Aesculap's OrthoPilot 2 help a surgeon properly align the implant, making it reliable and minimizing the stress on the cement bond between bone and implant (one of the most common failures of joint replacements).
“[OrthoPilot 2’s] high-tech accuracy and ease of use is helping to revolutionize knee surgery, improving … long- term surgical success rates.”
Aesculap knew it had cutting-edge technology; it came to frog for a world-class industrial design. Because the device would be physically and metaphorically at the surgeon’s side throughout the procedure, the goal was to design an equipment structure that would enable easy adjustment and visibility, without the technology getting in the surgeon’s way.
The OrthoPilot 2 uses a combination of optical, radio frequency, and ultrasound systems to assist the surgeon in three main ways: by accurately positioning the cutting guides, drills, and reamers; by providing measurements of bone alignment, and by indicating optimized angles and positions for implant placement.
Delivering that goal would demand nothing less than ergonomic perfection based on a deep understanding of how the surgeons worked. frog designed the system as a collection of modules in order to minimize unit size, maximize surgeons’ freedom of movement, and allow customization for the needs of individual hospitals and patients. A special 3-D camera, information unit, and
monitor provide the medical team with a highly accurate view of the implant’s every movement. frog also designed a flexible-arm system that makes it easy to handle both the monitor and the camera. A foot pedal adds a secondary level of control, keeping the hands of the surgical staff free to operate.
After 24 months fine-tuning the design, including comprehensive user testing and research into manufacturing methods to reduce costs, the OrthoPilot2 was successfully launched in April 2008.
