Abstract

The invention provides a high voltage bipolar steep pulse group tumor treatment device. The high voltage bipolar steep pulse group tumor treatment device comprises a main control unit, a steep impulsegenerating unit, an output control and monitor unit, and an output electrode needle unit. The main control unit is composed of a main control computer. The steep impulse generating unit comprises a steep impulse power source and an emergency stop button. The output control and monitor unit comprises a steep pulse output controller, a steep pulse output port, and a steep pulse output monitoring oscilloscope. The output electrode needle unit is a steep pulse electrode needle which is connected with the steep pulse output port. The invention further provides a high voltage bipolar steep pulse group tumor treatment system and method. When the device, the system, and the method are adopted to treat tumors, waveform output of the bipolar positive and negative steep pulse group is achieved, symmetrical electroporation holes can be formed in a cell membrane of tissue, uniformity of irreversible electroporation is improved, an ablation blind area is reduced, the hole diameter of the electroporation holes of the cell membranes on both sides is increased, the treatment effect of irreversible electroporation is improved, and the device can be widely used in tumor treatments of humans and animals.

Description

Technical field: [0001] The invention belongs to the technical field of tumor treatment, and in particular relates to a high-voltage bipolar steep pulse group tumor treatment device and system. Background technique: [0002] Irreversible electroporation (IRE) is a new tumor ablation technology related to tumor treatment. It forms nano-scale permanent perforation on tumor cells by releasing high-voltage pulses, destroying the internal balance of cells and causing rapid cell apoptosis. Numerous clinical studies have shown that this new technology is a safe and efficient tumor treatment technology. Compared with other tumor treatment technologies, it has the following advantages: (1) Short ablation time: a group of treatment takes less than one minute, so Even if there are three or four overlapping ablation zones, the whole ablation time will not exceed 5 minutes; (2) important tissues such as blood vessels and nerves in the treatment area are preserved: the new tumor ablation ...
