Abstract

The invention relates to a flexible microwave ablation needle under an ultrasonic endoscope. The flexible microwave ablation needle comprises a handle, a radio-frequency coaxial connector and a microwave radiating antenna, wherein the radio-frequency coaxial connector is arranged on the handle, the radio-frequency coaxial connector is connected with the microwave radiating antenna through a radio-frequency coaxial cable, the periphery of the radio-frequency coaxial cable is provided with a capillary tube and an inner tube in sequence, the radio-frequency coaxial cable is arranged in the capillary tube, the capillary tube is arranged in the inner tube, the inner tube comprises a first end portion and a second end portion, the first end portion extends to the microwave radiating antenna, thesecond end portion keeps away from the microwave radiating antenna, and the inner tube is tapered off gradually from the second end portion to the first end portion. The ablation needle can reach more lesion sites and has strong penetrability.

Description

technical field [0001] The invention relates to a flexible microwave ablation needle used for microwave ablation treatment of intra-abdominal tumors and diseased tissues, and relates to the field of microwave treatment medical devices. Background technique [0002] At present, my country's medical industry is developing by leaps and bounds. At the same time, the demand for products is becoming more and more refined. Microwave ablation, as a minimally invasive surgery, is more and more widely used. Microwave ablation uses the thermal effect of microwave biological tissues to treat lesions. Tissues can stop bleeding, coagulate, burn or reduce inflammation, reduce swelling, relieve pain, improve local tissue blood circulation, etc., to achieve the effect of treating diseases. It has the advantages of less trauma, quick effect, and strong penetration ability, and is accepted by more and more patients. [0003] Most of the existing minimally invasive microwave ablation operations...
