Puncture temperature measuring needle for high-voltage steep pulse tumor ablation

The puncture temperature measuring needle comprises a handle and a needle body, the rear end of the needle body is installed in the handle, the needle body comprises a ceramic puncture head, an optical fiber temperature measuring probe is installed in the ceramic puncture head, and the rear end of the optical fiber temperature measuring probe is connected with an optical fiber line. An optical fiber sleeve is sleeved outside the optical fiber cable and the optical fiber temperature measurement probe, and an insulating sleeve is sleeved outside the ceramic puncture head and the rear end of the optical fiber sleeve. Compared with the prior art, the nano-scalpel has the advantages that when the nano-scalpel ablates tumor tissue, the temperature measuring needle directly punctures the tumor tissue in a percutaneous mode, temperature detection is conducted on the ablated tumor tissue, the situation that blood vessels and nerves are damaged due to over-ablation is avoided, and operation safety and reliability are i
