Puncture simulation training model under guidance of mammary gland ultrasonic examination Technical Field The invention relates to the technical field of mammary gland ultrasonic detection training models, in particular to a puncture simulation training model under the guidance of mammary gland ultrasonic examination. Background In medicine, when the simulated mammary gland is subjected to ultrasonic intervention simulation training, the model of the simulated mammary gland mainly comprises a konjak gel model, an animal tissue model, a polyurethane silica gel high simulation model and the like. For the konjak gel model, the anatomical and physical simulation degree is low, so the konjak gel model is mainly used for puncture practice of the parts such as mammary glands. But has the fundamental defects of poor mechanical simulation degree, brittle and hard texture, lack of elasticity of real tissues, incapability of simulating biopsy cutting hand feeling, homogeneous and single structure and incapability of presenting breast fat-gland layering dissection. For animal tissue models, the individual difference of tissue characteristics is large, standardization cannot be achieved, biological safety risks and ethical problems exist, the preservation time is short, and in addition, specific human anatomy structures (such as mammary gland layering) cannot be simulated. For the polyurethane silica gel high simulation model, the price is extremely expensive (thousands to tens of thousands dollars), the puncture loss cost is high, and the focus is usually in a prefabricated fixed mode, so that the mode cannot be flexibly adjusted, and the diversity of training scenes is limited. Based on the method, a simulation model is designed, so that the method not only requires low cost and repeated use, but also can accurately simulate the ultrasonic imaging characteristics and puncture hand feeling of various typical focuses.
