Requirements of Teslaman TP3090 High Voltage Pulse Power Supply for Reversible and Irreversible Electroporation
Cancer is a serious threat to human life and health. According to data released by the World Health Organization, there will be 19.29 million new cancer cases and 9.96 million new deaths worldwide in 2020, including 4.57 million new cases and 3 million deaths in China, the highest in the world. first place.
There are many ways to treat cancer. According to the mechanism, there are two kinds, one is to stimulate the body's immunity, and the other is to reduce the tumor load. According to the form of energy, it can be divided into surgery by mechanical energy, radiotherapy by nuclear energy, hyperthermia by thermal energy, phototherapy by light energy, cell and vaccine therapy by chemical energy, and now a new method has been added is pulse. Electric field therapy.
After years of development, pulsed electric field therapy has reversible electroporation and irreversible electroporation.
The reversible electroporation method is to form micropores on the cell membrane through the electroporation effect under the action of a pulsed electric field, so that the permeability of the cells is increased, so that macromolecules with low permeability can penetrate and treat cancer tissues. The cell membrane temporarily increases in permeability, creating an opportunity to deliver low-permeability molecules into the cell. This method requires the cooperation of therapeutic drugs.
In the irreversible electroporation method, the energy is compressed on the microsecond time scale through the high-voltage ultra-short pulse electric field, and the instantaneous high power is obtained on the load, which causes the irreversible electrical breakdown of the cell biodielectric and causes the cancer cells to die. The dielectric parameters and physical morphology of normal cells and tumor cells are significantly different, so the survival of normal cells can be effectively guaranteed. Moreover, this therapy does not damage the bile ducts, blood vessels and nerves in the ablation area, and has good targeting. It has the characteristics of controllable, visual and fast.
Teslaman's TP3090, TP3200 and various pulse power sources are widely used in major universities, research institutes and enterprises.
