The invention discloses a direction-adjustable high-temperature steam ablation needle device, which comprises a needle tube, a heat insulation sleeve, a direction adjusting tube, an adjusting driving rod and a direction adjusting mechanism, wherein steam outlet holes are distributed on the tube wall of the extending end of the needle tube; the direction adjusting tube is mounted in the needle tube; a rectangular hole is arranged on the direction adjusting tube; the adjusting driving rod is fixed on the direction adjusting tube; and rotation of the adjusting driving rod is adjusted by the direction adjusting mechanism. According to the direction-adjustable high-temperature steam ablation needle device, an air inlet tube, the needle tube and the steam outlet holes are arranged in a matched mode, so that steam is guided into a corresponding position to be subjected to high-temperature ablation, the steam can be liquefied into water after ablation, and the water can be conveniently sucked out; the steam outlet holes in the corresponding direction are conducted by rotating and adjusting the direction adjusting tube, so that an ablation direction is adjusted; and through cooperation of the adjusting driving rod and the direction adjusting mechanism, the direction adjusting tube can be rotationally adjusted and positioned.
Description
technical field [0001] The invention relates to an ablation needle device, in particular to a direction-adjustable high-temperature water vapor ablation needle device. Background technique [0002] At present, the ablation needle is the main surgical tool for ablation surgery. When it is used, the ablation needle is used to percutaneously puncture into the central area of the tumor. There is a 1mm-sized "micro-wave oven" on a certain point of the microwave needle. The microwave magnetic field released by it can Make the surrounding molecules rotate at high speed and heat up by friction, so that the tissue is coagulated, dehydrated and necrotic, and the purpose of treatment is achieved. However, the existing microwave ablation method can only be spherical ablation, which is not directional. If the shape of the tumor is irregular, then when the tumor edge is ablated, the normal tissue will be ablated when microwave ablation is used. Contents of the invention [0003] Purp...
