Abstract
A dexterous operation arm driven by modular joint time-sharing switching, the operation arm comprising a plurality of completely identical sub-sections, each sub-section comprising three parts: an external elbow assembly, an internal transmission assembly, and an elbow drive unit. The tail end of the operation arm can be connected to end effectors, such as claws, tweezers, scissors, and the like, to form a dexterous micro-device, which is mounted at the tail end of a minimally invasive surgical robotic system to assist in minimally invasive surgery. The operation arm modularizes operation arm joints, and separates the drive of each joint, which improves the flexibility of the operation arm, and can enable dexterously delivering an end effector to the vicinity of a lesion for surgery.
