Multipole radiofrequency needle tumor ablation with plasma radiofrequency needle
Dec 16, 2022
It is a new minimally invasive treatment technology for solid tumors emerging in recent years, which can free patients from the pain of operation. Compared with traditional treatment, it has the advantages of high efficacy, less trauma, less pain, faster recovery, no sequelae, no risk, and wide indications, and is hailed as a green treatment technology by domestic and foreign experts. The tolerance of tumor cells to heat is worse than that of normal cells. Local heating to 39-40℃ can make cancer cells stop dividing, 41-42℃ can cause cancer cell death or DNA damage, and irreversible cell damage occurs above 49℃. The cluster electrode radio-frequency electrode sends out high frequency radio-frequency waves to stimulate tissue cells to carry out plasma shock. The heat generated can make the local temperature reach more than 90℃, so as to kill tumor cells quickly and effectively.
The principle of this technology is that under the guidance of CT and color B-ultrasound, the ablation electrode of the multi-pole female needle is accurately inserted into the tumor site, and the plasma radiofrequency instrument conducts the radiofrequency pulse energy through the multi-pole needle to the tumor tissue under the control of electronic computer, so that the tumor tissue generates local high temperature (70 ℃ -95 ℃). Thus, the tumor tissue and the adjacent tissues that may be spread are coagulated and necrotic, and the necrotic tissues are institutionalized or absorbed in situ.
