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).
