A tumor ablation system includes a heating needle and a power supply device. The heated needle includes a rigid tubular outer casing. The heating needle further includes a heat generating portion and at least one heat generating wire, a central cylinder and a distal end portion of the outer casing, wherein the heat generating wire and the central cylinder are located in the outer casing, The heating wire is electrically connected to the non-heating portion, and the heating wire is wound around the central cylinder to form a coil, wherein a distal end portion of the outer casing covers the coil formed by the heating wire on the central cylinder And wherein when the heating wire is energized, the heating wire generates thermal energy to be transmitted to a distal end portion of the outer casing. The power supply device is coupled to the non-heat generating portion, and the power supply device supplies power to the heating needle. |
