2450MHz微波电疗机如使用微波双极辐射器(《解放军医学杂志》1985;(3):220.),配接针电极组成微波针,可将微波能量集中于很小面积,能对病变组织进行高温烧灼,扩大微波治疗疾病的范围。 一、微波针烧灼疗法简介 1. 微波针结构原理:微波针由微波双极辐射器A、针柄B、针头C1或C2组成(附图)。图中:A由南京金属元件厂WL-1型或株州电子设备厂LW-752型微波机的圆柱形辐射器(辐射器),配接微波转换器(转换器)组成;B由两只香蕉插头用锡焊接而成,C1用6-9号注射针头;C2用9号注射针头,将针管部份齐根剪去磨光,其端面呈圆形,直径3mm。A、B、C1连接时组成放电烧灼微波针,A、B、C2连接时组成表浅烧灼微波针。B和C1、C2连接插入A插口时,即成为天线辐射微波,天线同时具有双线电路馈电特性,它与转换器的阻抗匹配无严格要求,但长度短时微波能量损失小输出强,故长度以方便操作较短为宜。
2450MHz microwave electrotherapy machine such as the use of microwave bipolar radiators (“PLA Medical Journal” 1985; (3): 220), with needle electrodes composed of microwave needles, the microwave energy can be concentrated in a small area, can be carried out on diseased tissue High-temperature burning, expanding the scope of microwave treatment of disease. First, the introduction of microwave needle burning therapy 1. Microwave needle structure principle: microwave needle by the microwave bipolar radiator A, needle handle B, needle C1 or C2 composition (with photos). Figure: A by the Nanjing metal components factory WL-1 or Zhuzhou electronic equipment factory LW-752 type of microwave oven cylindrical radiator (radiator), with the microwave converter (converter); B consists of two Banana plugs welded with tin, C1 with 6-9 injection needle; C2 needle with No. 9, the needle part of the root cut to polish, the end of a round, diameter 3mm. A, B, C1 connected to form a firing consumable microwave needle, A, B, C2 composed of superficial cautery microwave needle. B and C1, C2 connected into the A jack, the antenna will become the radiation microwave antenna also has a two-wire circuit feed characteristics, which match the impedance of the converter without strict requirements, but the length of a short microwave energy loss small output strong Length to facilitate the shorter operation is appropriate.
