Bone cyst surgery robot with bendable drilling and remote control

Abstract Limited by rigid instruments, traditional open curettage of bone cysts requires large incisions and the removal substantial amounts healthy tissue to approach lesion. This causes a lengthy recovery period with an increased risk for complications. While other less invasive methods have been suggested, none accepted as standard treatment modalities, many them not applied beyond academic studies. We propose fully robotic compliant joint-based endoscopic surgery system capable minimally cysts. A drilling robot optimized bend removes lesion, while provides visual feedback well suction irrigation cleaning inner bone. Two leader devices are used precisely control movement each in leader–follower configuration. The performance proposed was evaluated series experiments on animal femurs.
