The PHACON Spine Patients are artificial specimens to practice different spine surgeries. They are removed after the training session and can be replaced easily by a new model. This concept achieves a cost-saving course organisation, because only the Cervical Spine Patient is exchanged from the trainer. To automatically detect injuries of risk structures, the models contain electronic sensors (electrical detection). The PHACON Thoracic Spine Patients can be reordered at PHACON any time.
