Abstract: The disclosure relates to a chemical ablation apparatus for treating arrhythmia. The apparatus includes a clamp body, a clamp head consisting of a pair of clamp jaws, a needle head assembly, a needle head extension and retraction control assembly, pipeline components, and an electrocardiographic mapping component. The chemical ablation apparatus can control needle heads to extend out of or retract into the clamp head by means of the needle head extension and retraction control assembly. A chemical ablation reagent may be injected to a cardiac muscle tissue to conveniently achieve complete ablation of the cardiac muscle tissue by applying a chemical ablation method. The ablation effect can be verified by an electrocardiographic mapping system, to increase the success rate and lower the difficulty level of arrhythmia ablation operations, while also reducing the manufacturing cost of ablation apparatus and corollary equipment thereof, and decreasing expenses for atrial fibrillation surgical operations.
