Controllable non-invasive extended implantable electric artificial prosthesis

The utility model provides a controllable non-invasive extended implantable electric artificial prosthesis which mainly comprises an artificial prosthesis and an in-vivo and in-vitro controller, and the artificial prosthesis is composed of a moving body, a rotating body, a sealing shell, a transmission box, a micro motor and the like. The in-vivo controller is mainly composed of a control printed circuit board, a microcontroller, an energy storage battery and a wireless charging coil. The in-vitro controller is mainly composed of a signal transmitting end and a wireless charger. According to the utility model, after a signal is transmitted to the in-vivo controller through Bluetooth, the micro motor makes a corresponding instruction to drive the rotating body to rotate so as to push the moving body to move forwards, so that the extension effect is achieved. By means of the device, limb extension can be carried out for many times, and infection risks and psychological burdens brought to a patient by repeated o
