The electrotungsten fire needle tumor ablation system provided in this application embodiment is used to achieve precise, safe, and effective ablation of tumors. Currently, tumor thermal ablation technology has certain limitations. Radiofrequency / microwave ablation suffers from uneven heat field distribution and limited ablation range, while traditional fire needle therapy lacks a precise temperature control system, making it difficult to meet the requirements of modern tumor treatment for precision, safety, and effectiveness. Therefore, developing a novel tumor ablation system has significant practical implications. To this end, this application embodiment provides an electrotungsten fire needle tumor ablation system to achieve precise, safe, and effective ablation of tumors. The following detailed description, in conjunction with specific accompanying drawings, illustrates the system.
