Abstract

The invention relates to a device for a radioactive ion to radiate and induce a cell for damaging at a short distance. The device comprises a culture dish, a protecting cover, a control push rod and a radioactive ion loading plate, wherein the protecting cover is mounted above the culture dish in a sleeving manner; the bottom of the culture dish is loaded with cells ready for an experiment; the control push rod is connected with the radioactive ion loading plate; the control push rod drives the radioactive ion loading plate to move up and down in the protecting cover. The device is simple in structure, is high in safety, is convenient to use, can be repeatedly used, low in cost, and is suitable to popularize; a material is obtained easily; high pressure and ozone can be adopted for sterilization.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a device for radiating particles to induce cell damage by close-range radiation. Background technique [0002] Malignant tumors have the characteristics of insidious onset and difficult to cure, and have seriously threatened the health of the people. The treatment methods mainly include three methods: surgical resection, radiation therapy and chemotherapy. At present, early surgical resection is still the main method for the treatment of various cancers. However, most patients are already in the advanced (advanced) stage of cancer when they are diagnosed, and lose the opportunity for surgical resection; The curative effect is not good because of the limited sensitivity of radiation, and systemic chemotherapy not only has very limited effect, but also has huge side effects. [0003] At present, many malignant tumors, including liver cancer, have been proved to be sensitive t...
