Surgical Robots towards the Design Concept of an Intelligent Tool for Bone Resection in Total Knee Arthorplasty

A robot with only high positioning accuracy is still not adequate for surgery application. Modularization and intelligent human machine interface are the two crucial ones among the key factors for a successful medical robot in surgery applications. These two factors have to be put into consideration during designing a medical robot at the first place. Base on the viewpoint, a new architecture of a surgical robot for orthopaedics applications has been proposed. The new type of robot has also been compared with the past versions of surgical robots developed in the authors' laboratory. Its advantages in clinical application have also been verified by orthopaedics surgeon on cadaver test and the results justified the new design concept.
