Clinical efficacy and performance evaluation of a bendable remote robot system for a bone tumour surgery: A pilot animal study.

Background: Traditional open surgery for bone tumours sometimes has as a consequence an excessive removal of healthy bone tissue because of the limitations of rigid surgical instruments, increasing infection risk and recovery time.

Methods: We propose a remote robot with a 4.5-mm diameter bendable end-effector, offering four degrees of freedom for accessing the inside of the bone and performing tumour debridement.
