Stanmore Sculptor RGA (Robotic Guidance Arm)

Stanmore Sculptor RGA is a unique bone sculpting solution based on Stanmore's patent protected 'Active Constraint' technology, which confines a bone cutting tool by hardware and software to a defined volume in space (creating a 'no-fly zone') as determined by the surgical plan created in Stanmore's proprietary Planner software.

The Stanmore Sculptor RGA system is a robotic guide to assist with bone preparation to receive patient specific implants designed by Stanmore Implants. Bone sculpting is performed by a high speed cutting burr attached to the robotic arm. A second mechanical tracking arm is attached to the bone that is being sculpted to accurately track the cutting burr location relative to the bone. This surgeon controlled system features an interactive touch screen which the surgeon uses throughout the procedure.

The Active Constraint concept was used successfully in a randomised, double blind comparative clinical investigation in 2004 (published in Journal of Bone & Joint Surgery; 2006) where a number of unicompartmental knee replacements were carried out using the Sculptor RGA system and a number of conventional surgeries were carried out as a control group. The study demonstrated that the Sculptor RGA system consistently and accurately enabled the positioning of a prosthetic implant according to a surgical plan. 100% of Sculptor RGA cases were implanted within 2° of a desired orientation versus 40% for the conventionally implanted control group.
