An anti-displacement coil spring-type spine stabilization device includes: a coil spring member made of a spiral spring wire having multiple continuous loops, the coil spring member having the form of an elongated bar two connection members securely connected with two ends of the coil spring member, opposite end faces of the two connection members being respectively formed with two axially extending sockets and at least one elastic bar disposed in the coil spring member and axially extending through the coil spring member with two ends of the elastic bar respectively extending into the sockets of the connection members. The coil spring member is made of the spiral spring wire so that two ends of the coil spring member are naturally formed with threads, which can be directly screwed on the connection members without further mechanically processing. This simplifies the manufacturing process to lower the manufacturing cost.
