Abstract

The invention discloses a multifunctional cold circulation concentrated beam radiofrequency treatment probe, which comprises an operating handle, wherein a concentrated beam consists of two or more liquid medium enhanced hollow cooling radiofrequency electrodes; the center of the concentrated beam is provided with a multifunctional channel for injecting a liquid medium into a tissue or embedding a solid medium or measuring the temperature or performing tissue biopsy; and the multifunctional channel and the concentrated beam are fixed on the operating handle. The ablation size of a radiofrequency tissue is enlarged remarkably, treatment effect is enhanced by injecting a liquid medium into the tissue or embedding the solid medium and various functions such as biopsy, temperature measurement, liquid medium injection, solid medium embedding and the like are achieved.

Description

technical field [0001] The invention relates to a medical device for ablation of human tissue, in particular to a multi-functional cold cycle cluster radio frequency treatment probe for thermal inactivation of human solid tumors or pathological tissues. Background technique [0002] Radiofrequency tumor ablation (Radiofrequency Tumor Ablation, RFA) is a new method of minimally invasive treatment, which has been more and more widely used clinically, and the treatment electrode is the key technology in this field. The radio frequency current generated by the generator is released into the target tissue through the electrodes inserted into the human body, causing ion vibration and friction in the target tissue to generate heat, causing the temperature of the target tissue to rise, causing it to coagulate and necrosis, and destroying the diseased tissue, thereby achieving the purpose of treatment. [0003] The existing radio frequency treatment electrode has a limited treatment ...
