Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like figure 2 ,like Figure 4 , an electrode needle system of an adjustable water injection ablation electrode needle, comprising: a needle bar (1), a needle bar fixing seat (6), a water pipe fixing seat (7), a water pipe (80), and a radio frequency cable assembly (8) The needle bar holder (6) and the water pipe holder (7) are hermetically connected, and a cavity is formed between the needle bar holder (6) and the water pipe holder (7), and this cavity is connected with the hollow inside the needle bar (1) The structure is connected, and one end of the water pipe (80) is connected to the water pipe fixing seat (7) so that the water pipe (80) communicates with the inside of the needle bar (1). One or more pores (102) are opened on the rod (1), and the pores (102) communicate with the hollow structure inside the needle rod (1), and then communicate with the wat...

Abstract

The invention provides an electrode needle system of an adjustable water injection ablation electrode needle. The electrode needle system is characterized by comprising a needle bar (1), a needle bar fixing base (6), a water tube fixing base (7), a water tube (80) and a radio frequency cable assembly (8), wherein the needle bar fixing base (6) is connected with the water tube fixing base (7) through a sealing manner, a cavity is formed between the needle bar fixing base (6) and the water tube fixing base (7), the cavity is communicated with a hollow structure inside the needle bar (1), and one end of the water tube (80) is connected with the water tube fixing base (7) so that the water tube (80) is communicated with the inside of the needle bar (1). According to the electrode needle system, the water tube and a radio frequency cable are integrated, so that the breakage phenomenon seldom occurs, the adhesion to a coating can be prevented, and the problem of tissue adhesion caused by high-temperature heating can be improved or solved; and meanwhile, liquid can exude through the water tube at the front end of the needle bar, so that the effects of reducing the temperature and cooling can be realized.

Description

technical field [0001] The invention relates to a disposable radiofrequency ablation device, in particular to an electrode needle system of a temperature-controlled radiofrequency adjustable water injection ablation electrode needle for radiofrequency ablation treatment of tumors and diseased tissues. Background technique [0002] With the advancement of technology and oncology, radiofrequency ablation has become an effective way to treat cancer. Radiofrequency ablation generally uses local anesthesia, and CT or B-ultrasound scans are used to locate the signs of disease. After the electrode needle is inserted into the center of the lesion, the output power of radiofrequency ablation is automatically adjusted by monitoring the changes in the impedance, temperature and other parameters of the lesion tissue. Start radiofrequency ablation to rapidly produce large-scale coagulation necrosis in the lesion tissue. At present, there are two methods of radiofrequency ablation, one i...
