Thermosensitive microwave ablation needle testing tool

The utility model relates to a thermosensitive microwave ablation needle testing tool which comprises an inner sleeve with an inner cavity and a shell arranged outside the inner sleeve in a sleeved mode, the inner sleeve is provided with a blind hole allowing a microwave ablation needle to be inserted, and the inner cavity of the inner sleeve is filled with microwave heat absorption materials. The shell is a thermosensitive color-changing shell, or the outer surface of the shell is covered with a thermosensitive color-changing coating or pasted with a thermosensitive color-changing sticker. During operation, a microwave ablation needle is inserted into the blind hole, microwave emission is started, after the microwave heat absorption material in the inner sleeve absorbs microwave energy, the temperature of the liquid rises, the temperature of the shell rises along with the temperature, and when the temperature of the shell reaches the set temperature, color change starts; along with the increase of microwave
