Microwave ablation probe

A microwave ablation probe (200; 300); 400), comprising: an applicator (202; 302; 402) arranged to apply microwave radiation to heat surrounding tissue; the feed line (204; 304, 304; 404) arranged to supply electromagnetic energy to the applicator; a coolant flow path (206) through which coolant can flow; a choking coil arranged to reduce a flow from the applicator (202; 302; 402) along the feed line (204; 304, 304; 404) the reflected power. The choke comprises a choke member (208; 208 ') cooled by a coolant flowing in a coolant flow path (206). 209, 209; 308, 308; 408) for a motor vehicle. The choke member (208; 209, 209; 308, 308; 408) extends between two points spaced apart in a direction of at least an assembly having a longitudinal axis parallel to the feed line. The choke member (208; 209, 209; 308, 308; 408) includes one or more turns extending around a longitudinal axis of the feed line. The choke member may be a helical member (208; 308, 308; 408) for a motor vehicle. 一种微波消融探针(200；300；400)，包括：涂药器(202
