Description

Technical Field

[0001] The utility model relates to the technical field of electric field therapy equipment for tumors, in particular to a lifting device for electric field therapy equipment. Background Art

[0002] The tumor electric field therapy device is a device that uses electric fields to treat tumors. The electric field therapy device generates a low-intensity, medium-frequency alternating electric field, which acts on the microtubules of proliferating cancer cells, interferes with tumor cell mitosis, causes affected cancer cells to undergo apoptosis and inhibits tumor growth. Compared with traditional treatments such as surgery, radiotherapy and drug therapy, the tumor electric field therapy has fewer side effects due to its local delivery mode and anti-mitotic effect, and is therefore widely used.

[0003] Common electric field therapy devices are fixedly installed in the treatment environment, and the patient lies on a supporting platform. The movement of the supporting platform drives the patient to move into the interactive electric field generated by the electric field therapy device, so as to treat the tumor patient.
