A1

An implant delivery handle, an implant system, an implant delivery system and a use method therefor. The delivery system of the implant delivery handle comprises a lead screw, an inner tube connector, an outer gear, and an inner gear, wherein the outer gear is rotatably connected to the inner gear and used for driving the inner gear to rotate, the lead screw is connected to a first inner tube (11) or a second inner tube (12) by means of the inner tube connector, and the lead screw is further connected to the inner gear and rotates along with the inner gear so as to drive the first inner tube (11) or the second inner tube (12) to move in an axial direction, wherein a transmission ratio of the outer gear to the inner gear is greater than 1, such that the outer gear and the inner gear form a planet wheel. By combining the planet wheel and the lead screw, the transmission rate of the implant delivery system is improved, the operation time is shortened, and the residence time of an instrument in the body of a patient is reduced, and thus, the risk of accidents in the operation is reduced.
