Abstract

The invention provides pulse generation equipment and a control method thereof. The pulse generation equipment comprises a control circuit, a power supply circuit and a pulse generation circuit; the control circuit and the power supply circuit are electrically connected with the pulse generation circuit, and the control circuit is also electrically connected with the power supply circuit; and the control circuit is used for controlling the pulse generation circuit, so that the pulse generation circuit outputs bipolar pulses or unipolar pulses. By controlling the pulse generation circuit, the pulse generation circuit outputs bipolar pulses or unipolar pulses, so that electric field distribution in a target tissue area during tumor cell treatment is more uniform, and the tumor ablation effect can be greatly improved.

Description

technical field [0001] The present application relates to the technical field of signal generating devices, and in particular, the present application relates to a pulse generating device and a control method for the pulse generating device. Background technique [0002] Since IRE (Irreversible Electroporation) ablation of tumors was approved for clinical use, it has become more and more widely used and has achieved good therapeutic effects. [0003] However, with the deepening of clinical research, it is found that IRE has the following problems in ablation of tumors: due to the stimulation of pulsed electric fields, muscles and nerves will trigger action potentials, resulting in muscle contraction, which will increase the pain of patients in clinical treatment, and It is easy to cause the displacement of the electrode needle, resulting in the inaccurate control of the ablation area; due to the uneven distribution of the electric field in the tissue, the local ablation of t...
