Targeted cell ablation method and system

Abstract

An embodiment of the invention discloses a targeted cell ablation method and system. The method comprises steps as follows: a switch power supply is turned on, a single chip microcomputer in a singlechip microcomputer control circuit is initialized, and a relay and a drive circuit are configured; the single chip microcomputer controls the relay and the drive circuit to generate positive and negative pulses for target ablation of target cells; and the positive and negative pulses are applied to target cells for target ablation. Therefore, targeted cell ablation is effectively performed, and muscle tremor is effectively reduced as well.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular to a method and system for targeted ablation of cells. Background technique [0002] In the current tumor treatment, whether it is traditional radiotherapy, chemotherapy, or emerging treatment technologies such as hyperthermia, molecular immunotherapy, etc., clinically there are dose-limiting toxic DLT, biological resistance or escape, and off-target effects that cause residual tumors and tumor cell resistance. And immune system damage, etc., can lead to medical problems such as poor prognosis of patients, tumor recurrence and tumor metastasis. Under the severe situation of rising tumor morbidity and mortality in our country, for malignant tumors with high recurrence and high metastasis, how to overcome the resistance and variability of tumor cells and effectively inhibit recurrence and metastasis after treatment is a safer and more effective ...

Problems solved by technology

Although the microsecond pulse irreversible electroporation technology, as a new tumor ablation technology, has achieved exciting therapeutic effects in clinical applications at home and abroad, in the face of complex and changeable tumor cells with various shapes and their latent tumor cells For tumor stem cells in the population, microsecond pulses target the outer membrane of tumor cells to induce their electroporation or lead to the escape of morphologically heterogeneous tumor cell subpopulations within the tumor cell population and the escape of malignant tumor stem cell subpopulations latent in the tumor population , leading to incomplete tumor ablation, or large side effects caused by treatment techniques, causing recurrence and metastasis after treatment, affecting the health of patients
