The evolution of traditional surgical techniques and training models of surgeons require changes. For this reason the centre of research and training in minimally invasive surgery (CLEMI) has developed and applied teaching models that help in the training of minimally invasive surgical techniques such as the endoscopy of the spine. CLEMI proposes a model based on simulation taught in a controlled, structured, and progressive environment that is adjusted to the individual rhythm of each of the participants. The student will initially encounter the theoretical concepts of instruments, equipment, and the surgical technique. This will be followed by a practical phase in which the acquired concepts will be applied using a sawbone model of the lumbar spine. Finally the practice will be carried out on a human anatomical model on which they develop, in a complete and guided manner, the different endoscopic procedures used at the lumbar level. Model training in a controlled environment decreases the learning period and increases student skills.
