Product Brief Introduction：

The puncture training model is a product with a highly simulated design concept, applying domestic advanced molding technology, made with new polymer simulation materials, and simulating the real puncture plot throughout the operation.  

 
Functional Parameters：
1. The simulated standardized patient takes a lateral lying position, the back is perpendicular to the bed surface, the head is bent forward to the chest, the knees are flexed to the abdomen, and the trunk is arched.
The waist can be moved. The operator needs to hold the simulated patient's head with one hand and hold the lower limbs at the popliteal fossa with the other hand to make the spine as wide as possible and widen the intervertebral space to complete the puncture.
2. The lumbar tissue structure is accurate and the body surface marks are obvious: there are complete 1-5 lumbar vertebrae (vertebral body, vertebral arch plate, spinous process), sacrum, sacral hole, sacral angle, supraspinous ligament, interspinous ligament, ligamentum flavum, The dura mater and the bead omentum, as well as the subdural space, epidural space, and sacral canal formed by the above tissues; the posterior superior iliac spine, iliac crest, thoracic spinous process, and lumbar spinous process can be truly touched.
3. The following operations are feasible: lumbar anesthesia, lumbar puncture, epidural block, caudal nerve block, sacral nerve block, lumbar sympathetic nerve block.
(1) Simulation of lumbar puncture simulation: When the puncture needle reaches the simulated ligamentum flavum, the resistance increases and there is a sense of resilience.
(2) Breaking through the yellow tenacity with a clear sense of emptyness, that is, entering the epidural space and showing negative pressure (at this time, the injection of anesthetic liquid is epidural anesthesia).
(3) Continued needle insertion will puncture the dura mater and the bead omentum, and a second sense of emptyness will appear, that is, enter the subdural cavity, and there will be simulated cerebrospinal fluid outflow, which simulates the real plot of clinical lumbar puncture throughout the course.
Note: Both the skin and the simulated spinal cavity can be replaced, and supplies are available.
