The invention discloses a 
robotic surgery micro-device for minimally 
invasive surgery and relates to a 
surgery micro-device. The invention aims at solving the problem of the existing 
robotic surgery of inflexible operation. The 
robotic surgery micro-device for minimally 
invasive surgery comprises a quick change joint (1), as well as a micro-device driving mechanism (2), a guide rod (3), a 
wrist mechanism (4) and an end 
effector (5), wherein the quick change joint (1), the micro-device driving mechanism (2), the guide rod (3), the 
wrist mechanism (4) and the end 
effector (5) are connected in sequence from 
right to left. The robotic 
surgery micro-device for minimally 
invasive surgery disclosed by the invention is especially suitable for being applied in a 
robot auxiliary system and is controlled by a doctor to clamp, 
cut and separate nidus in the 
abdominal cavity of a patient and finish such surgical operations after the operation as sewing and knotting through the end 
effector by means of the control and drive of the micro-device driving mechanism. The robotic 
surgery micro-device for minimally invasive surgery disclosed by the invention is applied in abdominal surgeries.
