Disclosed is an in-vivo micro-robot for nerve stretching, comprising a channel, and a movable part and a fixed part located at the channel. The movable part is disposed to be movable along the channel, the movable part sleeves the fixed part and is used for driving the fixed part to move along the channel, and the fixed part is connected to a nerve to be stretched. The in-vivo micro-robot is embedded into a patient's body through surgery, so that the extension of the nerve is accelerated and is regular and quantitative, thereby effectively solving the problems of small probability of nerve self-repair and long recovery period in traditional nerve bridging surgery.
