The invention discloses an auxiliary implantation system and method for a flexible neural electrode with an integrated sensing needle tip, and belongs to the technical field of electrode implantation. The invention aims to solve the problem that the implantation precision is affected due to the fact that an existing neural electrode does not have the fine sensing and distinguishing capability on biological tissues in the implantation process. According to the system, a guide rod is arranged in a packaging shell; the outer surface of the guide rod is provided with a lead coating as an electric connection end; the actuating mechanism is sequentially connected with the guide rod, the quartz crystal oscillator and the microneedle, and the tail end of the microneedle extends out of the packaging shell; two pins of the quartz crystal oscillator are respectively connected with the two electric connection ends; driving voltage of the signal generation and acquisition module is output to one pin of the quartz crystal
