The tumor interventional thermal therapy instrument comprises a barrel composed of an inner barrel and an outer barrel, a piston is arranged in the inner barrel, a push rod is connected to the rear end of the piston and extends out of the inner barrel, a sleeve head extending out of the outer barrel is arranged at the front end of the inner barrel, a needle head is fixed to the front end of the sleeve head, and an overflow pipe communicated with an inner cavity of the inner barrel is fixed to the top of the inner barrel. The upper end of the overflow pipe extends out of the outer cylinder andis sleeved with a dustproof cover, an isolation plug is fixed in the overflow pipe, and a first channel and a second channel are formed in the upper end and the lower end of the overflow pipe respectively and communicated with the isolation plug. The device is simple in structure, and the manufacturing cost is reduced; and when the injection speed is too high, the redundant reagent can overflow through the isolation plug
