Document Type and Number:
WIPO Patent Application WO/2022/262045
Kind Code:
A1
Abstract:
A modularized flexible operation arm based on a single power source, comprising a plurality of identical sub-sections, each sub-section comprising an external elbow assembly, a transmission assembly and an internal elbow driving assembly. The tail end of the modularized flexible operation arm may be connected to tail end execution mechanisms, such as claw forceps, tweezers and scissors, to form a flexible micro instrument which is mounted at the tail end of a minimally invasive surgical robot system to assist with carrying out minimally invasive surgery. In the operation arm, joints of the operation arm are modularized, and the driving of each joint is independent, which improves the flexibility of the operation arm, and can achieve the flexible sending of a tail end execution mechanism to near a lesion for surgery.
