1. An implantation system for implanting a flexible neural electrode, wherein the implantation system comprises:
a flexible neural electrode on which an auxiliary implantation part is provided; and
an auxiliary implantation assembly comprising a cannula assembly and a guide wire, the cannula assembly comprises an inner cannula and an outer cannula sleeved outside the inner cannula, the guide wire is made of a shape memory material and has a retracted state in which it is retracted within the inner cannula and an extended state in which it penetrates out of a distal end of the inner cannula, and an extended end of the guide wire is connected to the auxiliary implantation part,
wherein, when the guide wire is in the retracted state, the flexible neural electrode is in a curled state in which it is curled between the inner cannula and the outer cannula, when the guide wire is in the extended state, the guide wire is configured to form a target shape conforming to an outer contour of the flexible neural electrode under the influence of the environment, and the flexible neural electrode moves to an intended target area along with the guide wire and unfolds, so as to transition from the curled state to an unfolded state, thereby enabling the flexible neural electrode to be flatly adhered to the intended target area;
wherein a bent part is formed at a distal end of the guide wire, and the bent part is penetrated through the auxiliary implantation part, so as to drive the flexible neural electrode to move via the guide wire.
