A multifunctional microwave ablation needle with efficient cooling

Abstract

The invention discloses an efficiently cooled multifunctional micro-wave ablation needle. The efficiently cooled multifunctional micro-wave ablation needle comprises a handle and an ablation needle rod, wherein the ablation needle rod comprises an outer sleeve; a needle head is arranged at the front end of the outer sleeve; a cable connecting a handle with the needle head is arranged in the outersleeve; a sleeve cavity is formed between the outer sleeve and the cable; a cooling tube adjacent to the cable, a silica fiber and a temperature sensor are arranged in the sleeve cavity; and a light transmitting portion is arranged at the front end, which corresponds to the silica fiber, of the outer sleeve. The provided ablation needle can be in combination with a 3D laser imaging technology, anoptical fiber temperature-control technology and an intelligent control system, the shape of ablation and solidification of the ablation needle can be controlled accurately and effectively, and a clinical requirement for inactivating tumors is met; and in a treatment process, the size of a solidified tumor can be confirmed under the guidance of imaging equipment such as CT and MRI, by the technology, the microwave radiation range can be controlled accurately, a tumor region is covered effectively, thorough treatment is ensured, the tumor is unlikely to relapse after a surgery, and the living quality of people can be improved well.

Description

technical field [0001] The invention relates to a microwave radiation ablation needle, in particular to a highly efficient cooling multifunctional microwave ablation needle. Background technique [0002] Current tumor treatment methods include traditional surgery, chemotherapy, radiotherapy, ablation (argon-helium knife, radiofrequency, microwave), etc. In the existing clinical treatment of tumors, each has its own characteristics and advantages, but also has its limitations and defects. Surgery cannot be performed on some advanced and difficult-to-operate sites; chemotherapy will be distributed throughout the body after the drug enters the body, not only killing solid tumors and tiny invisible metastases, but also "manslaughter" the body Normal tissue, causing some negative effects; radiotherapy is to use radiation to kill cancer cells, the effect is obvious, but radiation can also damage normal tissue; ablation (argon-helium knife) is to treat tumors by cryotherapy, its e...

AI Technical Summary

Problems solved by technology

[0006] The ablation needle of the present invention can realize 3D laser imaging after improvement, solves the defect that the existing technology cannot monitor the solidification range in real time through 3D laser infrared imaging technology, and controls the actual ablation needle range through a temperature-controlled quartz optical fiber sensor; another On the one hand, by improving the cooling tube and its cooling cycle, the cooling effect is better and the pain of the patient's treatment is relieved
