Preparation method of phantom model for ultrasonic puncture teaching

The invention discloses a preparation method of a phantom model for ultrasonic puncture teaching. The preparation method comprises the following steps: preparing a phantom model shell; the preparationof the phantom model shell comprises the following steps: S11, mixing medical silica gel A and medical silica gel B according to a mass ratio of 1:1-1:2 to obtain a first mixed solution; S12, uniformly stirring and mixing the first mixed solution, and performing vacuum defoaming for 1-10 minutes to obtain a bubble-free first mixed solution; and S13, injecting the bubble-free first mixed solutioninto a mold, properly rotating the mold to enable the bubble-free first mixed solution to be uniformly smeared on the inner surface of the mold, after smearing is completed, putting a mold inner coreinto the mold, fixing the mold inner core, and curing the mold in an environment of 60-100 DEG C for 10-30 min to obtain the phantom model shell. The structure mode that the shell comprises the core layer is adopted, and the pr
