Lifelike appearance, realistic texture, lateral position

Waist movable

Accurate waist structure and obvious landmarks

The operations that can be performed: lumbar anesthesia, lumbar puncture, epidural block, caudal nerve block, sacral nerve block, lumbar sympathetic nerve block

Realistic puncture experience: when the puncture needle reaches the simulated ligamentum flavum, the resistance increases and there is a sense of toughness. When the puncture needle breaks through the ligamentum flavum, there is an obvious sense of empty, it means enters the epidural space and there has negative pressure, inject liquid to simulate epidural anesthesia. If the needle continues to be inserted, the endorhachis and arachnoid membrane will be punctured, and the second sense of empty will appea, it means enters the subarachnoid space, there will be outflow of simulated cerebrospinal fluid
