The main function of the spinal puncture model is to provide medical students, nurses and clinical doctors with a safe and intuitive teaching and practice platform, which is used to master common clinical operation skills such as lumbar puncture and subarachnoid puncture. This model is designed based on the real anatomical structure of the human lumbar vertebrae, featuring realistic tactile sensations of the vertebral body, spinous processes, intervertebral Spaces and skin layers. It can effectively help learners familiarize themselves with the positioning method of the puncture site and the needle insertion path.

Through the training of the spinal puncture model, trainees can repeatedly practice key steps such as the control of the puncture Angle and depth, and the extraction of cerebrospinal fluid, thereby enhancing the accuracy and safety of the operation. Models are usually equipped with replaceable modules and a simulated cerebrospinal fluid system, which can truly reproduce the process of fluid outflow, enhancing the authenticity of learning and clinical immersion. It can not only help beginners establish standardized operation procedures, but also be used for skills assessment and scientific research teaching. Overall, the spinal puncture model is of great significance in medical education, which helps to reduce clinical operation risks, improve the professional skills of medical staff and the safety guarantee level of patients.
