Tumor ablation device for radiotherapy assistance

Abstract

The invention provides a tumor ablation device for radiotherapy assistance, which belongs to the technical field of medical instruments, and comprises a tube body, a needle head, an ablation needle, adriving tube and an electricity control assembly, and is characterized in that a suction port communicated with an air pump is formed in the tube body; wherein the needle head is arranged at the front end of the tube body, a plurality of through holes are formed in the needle head, and the plurality of through holes are radially distributed around the axis of the needle head; the ablation needleis connected into the tube body in a sliding mode, a plurality of ablation heads are arranged at the front end of the ablation needle, and the ablation heads are connected with the through holes in asliding mode; the driving tube is arranged on the periphery of the ablation needle in a sleeving mode and connected with the ablation needle in a sliding mode, the driving tube makes conductive contact with the ablation needle, the front end of the driving tube is provided with a cutting blade distributed spirally, the cutting blade is arranged on the periphery of the ablation needle in a sleevingmode, and the head end of the cutting blade is fixedly connected with the needle head. The tumor ablation device for radiotherapy assistance provided by the invention is beneficial to rehabilitationof a patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a radiotherapy-assisted tumor ablation device. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors. [0003] Existing radiotherapy for tumors has a relatively shallow area of ​​action on tumor tissues with larger diameters, and the effect on tumor cells in the center of the tumor tissue is not obvious.
