1. Lifelike appearance, realistic texture, lateral position
2. Waist movable
3. Accurate waist structure and obvious landmarks
4. The operations that can be performed: lumbaranesthesia, lumbar puncture, epidural block, caudal nerveblock, sacral nerve block, lumbar sympathetic nerve block
5. Realistic puncture experience: when the puncture needlereaches the simulated ligamentum flavum, the resistanceincreases and there is a sense of toughness. When thepuncture needle breaks through the ligamentum flavum,there is an obvious sense of empty, it means enters theepidural space and there has negative pressure, injectliquid to simulate epidural anesthesia. If the needlecontinues to be inserted, the endorhachis and arachnoidmembrane will be punctured, and the second sense ofempty will appea, it means enters the subarachnoidspace, there will be outflow of simulated cerebrospinalfluid
