Chemical ablation apparatus for treating arrhythmia

A chemical ablation apparatus, comprising:

• a clipping component comprising a clamp body and a clamp head, the clamp head comprising a pair of clamp jaws installed on the clamp body and configured to clamp or release a target ablation tissue by a relative motion of the clamp jaws;
• a needle head component installed inside the clamp jaws, the needle head component comprising a needle head assembly, and a needle head extension and retraction control assembly, wherein:
• the needle head extension and retraction control assembly comprises an ablation reagent injection head and a plurality of needle heads installed on the ablation reagent injection head;
• the plurality of needle heads are configured to be used to inject ablation reagents into the target ablation tissue;
• the needle head extension and retraction control assembly is configured to control the plurality of needle heads to extend out of or retract into the clamp jaws;
• and
• a plurality of injection needle holes provided on a side of each of the pair of clamp jaws opposite another of the pair of clamp jaws for the plurality of needle heads to extend out of or retract into the clamp jaws;
• a plurality of pipeline components comprising ablation reagent transporting pipelines, the ablation reagent transporting pipelines being in fluid communication with the needle head extraction and retraction control assembly so as to transport the ablation reagents;
• an electrocardiographic mapping component configured to detect a conduction condition of at least one of electrocardiosignals or external electrical stimulus signals around the target ablation tissue;
• a spraying system comprising spraying holes arranged on the clamp jaws;
• and
• a suction system comprising suction holes arranged on the clamp jaws, wherein the spraying holes and the suction holes are connected to a spraying pipeline and a suction pipeline, respectively.
