Radio frequency needle

Abstract

The invention discloses a radio frequency needle. The radio frequency needle comprises a radio frequency needle body, an arm fixing device is arranged outside the radio frequency needle body, the arm fixing device comprises a support, an upper clamping frame is fixedly connected to the back face of the middle of the support, two suction cups are fixedly connected to the lower face of the support, a sponge pad is fixedly connected to the upper face of the support, two springs are fixedly connected between the front portion of the support and the front portion of the sponge pad, a shell clamping device is arranged outside the radio frequency needle body, and a displacement device is arranged outside the radio frequency needle body. According to the radio frequency needle, when the front portion of an arm is held, the front portion of the sponge mat is extruded downwards, the two springs below the front portion of the sponge pad can keep the sponge pad attached to a wrist of a user, the user can take up a needle tail box to use the needle tail box for a patient, the support and the arm of a medical worker are fixed, therefore, the stability in the using process can be improved, and shaking caused by single-hand holding is reduced.

Description

technical field [0001] The invention relates to the technical field of radio frequency needles, in particular to a radio frequency needle. Background technique [0002] Radiofrequency ablation therapy is a kind of physical therapy that uses radiofrequency current to excite high-speed oscillations of ions in tissues to collide and rub against each other to generate high heat to dehydrate tumor tissue cells and tissues to form local coagulation necrosis to treat tumors. Radiofrequency ablation treatment of tumors also depends on tumor tissue own biological properties. Due to the anatomical and histological defects of tumor tissue, there are characteristics such as insufficient blood supply, hypoxia, partial warming, and heat resistance, which provide a theoretical basis for radiofrequency ablation therapy. Tumor tissue cannot dissipate heat after absorbing heat energy, and its internal temperature can rise 5-9°C higher than that of healthy tissue, sometimes even as high as 10...

Problems solved by technology

[0003] When using radio frequency to perform acupuncture on patients, the general medical staff will pinch the radio frequency needle with one hand, but because the human hand will shake when suspended in the air, the pain of the patient will increase, which will make the patient feel stressed during the treatment and reduce the efficiency of needle injection
