Description

Radio frequency needle

Technical Field

The utility model relates to the technical field of radio frequency needles, in particular to a radio frequency needle.

Background

The radio frequency ablation therapy is a physical therapy for treating tumors by utilizing high-speed oscillation and mutual collision and friction of ions in radio frequency current excited tissues to generate high heat so as to dehydrate tumor tissue cells and tissues to form local coagulation necrosis, and the radio frequency ablation treatment of the tumors also depends on the biological characteristics of the tumor tissues. The tumor tissue has the characteristics of insufficient blood supply, oxygen deficiency, partial warmth, thermolabile property and the like due to the defects of the anatomical tissue, and provides a theoretical basis for the radio frequency ablation treatment. After the tumor tissue absorbs heat energy, the heat can not be dissipated, the internal temperature rise can exceed 5-9 ℃ of the healthy tissue, sometimes even reaches 10-11 ℃, and the internal temperature rise can be maintained for a long time. The selective action of the radio frequency energy on the cancer tissue can achieve the aim of killing the cancer tissue without damaging the normal tissue.

When the radio frequency is used for pricking a patient, a general medical worker can hold the radio frequency needle with a single hand, but the pain of the patient is increased due to shaking of the hand when the hand suspends in the air, so that the pressure of the patient is high when the patient receives treatment, and the pricking efficiency is reduced.
