Abstract

The invention relates to a pulse generation circuit and a high-voltage electric pulse tumor therapeutic instrument. The pulse generation circuit is applied to the high-voltage electric pulse tumor therapeutic instrument, and comprises a control circuit, a pulse generator and a surge protection circuit, wherein the control circuit is used for generating and outputting a pulse signal; the pulse generator is used for processing the high-voltage signal output by a charging circuit of the high-voltage electric pulse tumor therapeutic instrument under the control of the pulse signal to obtain a high-voltage pulse, and transmitting the high-voltage pulse to the charging circuit of the high-voltage electric pulse tumor therapeutic instrument; and the surge protection circuit is connected with thepulse generator and used for suppressing surge of the pulse generator. The pulse generation circuit can suppress surge in the high-voltage pulse generation process, absorb transient overvoltage and reduce interference of high-voltage pulses on pulse signals, and therefore stability and reliability of high-voltage pulse output are improved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a pulse generating circuit and a high-voltage electric pulse tumor therapeutic apparatus. Background technique [0002] High-voltage electric pulse tumor therapy instrument is a new type of instrument for treating malignant tumors, which combines biomedical engineering, high-voltage new technology, modern power electronics technology, computer technology and microelectronics technology. The working process of the high-voltage electric pulse tumor therapy instrument is generally as follows: the instantaneous electric field intensity of the electric field pulse applied to the cells is higher than 1kV / cm (kilovolts per centimeter), which greatly increases the molecular permeability of the cells, and then produces electroporation. The continuous increase of the pulse electric field intensity leads to irreversible electrical breakdown, which leads to mechanical rup...
