This disclosure provides an implantation device and an implantation
system. The implantation device includes: a receiving mechanism, the receiving mechanism including a first receiving portion; and an implantation component, the implantation component being housed in the first receiving portion, at least a portion of the implantation component being movable relative to the first receiving portion to drive the movement of electrodes attached to the implantation component; wherein the electrodes are capable of acquiring electrical signals from
biological tissue or applying electrical stimulation to
biological tissue. The solution of this disclosure can reliably improve at least one of implantation efficiency and implantation accuracy.
