Product characteristics
1. The waist can be moved. The operator needs to hold the simulated patient’s head with one hand and hold the leg socket of both lower limbs tightly with the other hand to make the spine kyphotic and widen the vertebral space as much as possible to complete the puncture. 2. The lumbar tissue structure is accurate and the body surface signs are obvious: there are complete 1~5 lumbar vertebrae (vertebral body, vertebral arch plate, spinous process), sacrum, sacral hiatus, sacral Angle, superior spinous ligament, interspinous ligament, yellow ligament, dura mater and omentum, as well as subomentum, epidural space and sacral canal formed by the above tissues: posterior superior iliac spine, iliac ridge, thoracic spine process and lumbar spine process can be truly felt. 3. The following operations are feasible: lumbar anesthesia, lumbar puncture, epidural block, caudal nerve block, sacral nerve block, lumbar sympathetic nerve block 4. Simulated reality of lumbar puncture: When the puncture needle reaches the simulated yellow ligament, the resistance increases and there is a sense of toughness, and the breakthrough of the yellow ligament has an obvious sense of disappointment. That is, into the epidural space, there is negative pressure (at this time, the injection of anesthetic liquid is epidural anesthesia): continue to inject the needle will puncture the dura and the omentum, there will be a second feeling of failure, that is, into the subomentum space, there will be simulated brain fluid outflow. The whole process simulates the real situation of clinical lumbar puncture.
