Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] refer to figure 1 As shown, an embodiment of the present invention is a submillimeter-scale tumor thermal ablation needle based on NV color centers, which consists of an ablation needle 1 , an ablation needle shaft 2 and an ablation needle tube 3 . The ablation needle is diamond particles with high NV color center content. The ablation needle 1 is seamlessly bonded to the front end of the ablation needle rod 2 by UV glue or low-melting glass powder, and the ablation rod 2 extends into the matching conical hollow capillary. In the ablation needle tube 3.
[0028] In this embodiment, the ablation needle tube 3 is a tapered hollow capillary steel tube matched with the optical fiber needle shaft 2, and the steel tube can be manufactured by cold pressing or high temperature drawing technology. When fixing the fiber optic needle rod, apply ...
