摘要:
A microwave ablation probe (200; 300; 400), comprising:an applicator (202; 302; 402) arranged to apply microwave radiation to heat surrounding tissue;a feeding cable (204; 304; 404) arranged to supply electromagnetic energy to the applicator;a coolant flow path (206) via which coolant is able to flow; and a choke arranged to reduce power reflected from the applicator (202; 302; 402) along the feeding cable (204; 304; 404). The choke comprises a choke member (208; 209; 308; 408) cooled by coolant flowing in the coolant flow path (206). The choke member (208; 209; 308; 408) extends between two points spaced apart in a direction having at least a component parallel to a longitudinal axis of the feeding cable. The choke member (208; 209; 308; 408) comprises one or more turns extending around the longitudinal axis of the feeding cable. The choke member may be a spiral member (208; 308; 408).
