Abstract: 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.

Abstract: A compound continuum robot for skull base tumor resection and a control method therefor. The robot includes a fixed base module, and a continuum mechanism, a notched continuum control mechanism, a concentric tube driving mechanism and a forceps opening and closing control mechanism which are arranged on the fixed base module. The continuum mechanism is sequentially composed of a concentric tube continuum mechanism and a notched continuum mechanism from interior to exterior, a bending motion and a rotating motion of the notched continuum mechanism are controlled by the notched continuum control mechanism, feeding and rotating motions of the concentric tube continuum mechanism are controlled by the concentric tube driving mechanism, and feeding and rotating motions of a forceps opening and closing control mechanism steel cable are controlled by the forceps opening and closing control mechanism, such that forceps are opened or closed.
