Abstract
The invention discloses a free combination radio frequency ablation needle. The free combination radio frequency ablation needle comprises a radio frequency source and an ablation needle, wherein the ablation needle comprises a needle body, one end of the needle body is connected with a needle head, the needle head is fixedly connected with the needle body, the other end of the needle body is fixedly connected with a connection wire, the connection wire is fixedly connected with a connection head, and the connection head is electrically connected with the radio frequency source. The free combination radio frequency ablation needle is not limited by work angles and tissue shapes, is convenient to use, decreases the number of ablation times, shortens operation time, retains tissue to the utmost, reduces pain of a patient, and reduces a bleeding volume.
Description
technical field [0001] The invention relates to a medical device, in particular to a freely combined radiofrequency ablation needle. Background technique [0002] Resection is still one of the main radical treatments for liver tumors, but intraoperative or postoperative bleeding is one of the most common and most difficult complications of liver surgery. Data show that about 20% to 60% of patients will have to receive blood transfusion due to surgical blood loss, and massive blood loss and blood transfusion are important factors affecting the prognosis and recurrence of liver cancer. How to control bleeding has always been the focus of liver surgery techniques. In recent years, radiofrequency ablation technology has been widely used in the treatment of the above-mentioned diseases because of its good ablation and hemostasis effect. However, the existing radiofrequency ablation needles are straight, which is convenient for laparotomy, but it cannot be convenient and smooth...
