AI Technical Summary

Technical Problem

Existing liquid embolization agents are only used for tumor vascular embolization, and the treatment method is single, and tumor cells after embolization may regenerate, which becomes a health threat.

Method used

A liquid embolization agent was developed, containing polymers, solvents and carbonyl iron powder. The carbonyl iron powder has development function and magnetothermal therapy function. It is implanted into the tumor lesion area through a microcatheter, and the embolization process is monitored by the development positioning of carbonyl iron powder, and a magnetothermal effect is generated under the applied alternating magnetic field, which can locally heat up and eliminate tumor cells.

Benefits of technology

It realizes the dual functions of liquid embolization agent development and magnetothermal therapy, which can completely eliminate and eliminate tumor cell regeneration, and improves the effectiveness and safety of treatment.

Abstract

The invention relates to a liquid embolism agent as well as a preparation method and an application method thereof, and belongs to the technical field of medical instruments. The invention discloses a liquid embolism agent which has a developing function and a magnetic hyperthermia function. The liquid embolism agent comprises a polymer, a solvent and carbonyl iron powder, wherein the carbonyl iron powder has a developing function and a magnetic hyperthermia function. The liquid embolism agent is prepared by using the compound carbonyl iron powder which has developing and magnetic hyperthermia effects at the same time, so that when the liquid embolism agent is implanted into a tumor focus area through a microcatheter to embolize tumor blood vessels, the embolism process can be monitored through developing and positioning of the carbonyl iron powder, and meanwhile, under an external alternating magnetic field, the embolism effect can be effectively improved. The carbonyl iron powder generates a magnetocaloric effect under the action of an external magnetic field, so that a focus part is locally heated, and tumor cell regeneration is thoroughly eliminated and eradicated.
