The invention relates to a magnetic-control liquid embolism robot and a magnetic-control embolism system, belongs to the field of medical instruments, and aims to solve the problems of ectopic embolism and reflux caused by incapability of resisting blood flow impact after a current liquid embolism material is injected into a body and difficulty in conveying the embolism material through a catheter in a relatively complex vascular structure. The invention provides a magnetically-controllable liquid embolism robot, which adopts a pure liquid embolism technology, is a mixed liquid of an embolism material and magnetic powder particles in vitro, enters an in-vivo blood environment through injection during use, is fixed at a target part through magnetic control, or flows to the target part in a complex and zigzag blood vessel through magnetic control and is fixed. The embolism is completed through the ionic cross-linking reaction in the blood environment and the complete solidification at the target part to jelly.
