This invention relates to the field of
medical education technology, and discloses an interactive teaching
system and method for simulating the biomechanical changes of the
cervical spine in people who frequently look down at their phones. The
system includes a
physical model module, a sensing and control module, and a
software visualization module. The
physical model module is constructed as a movable
cervical spine model, incorporating
ligament structures and flexible tubular structures to simulate nerves or blood vessels. The sensing and control module drives the
cervical spine model to produce flexion or extension movements via a drive mechanism, and collects biomechanical data during the cervical spine movement using pressure sensors, angle sensors, and tension sensors. The
software visualization module receives the sensor data, drives the virtual 3D cervical spine model to move synchronously, and displays the data as a pressure distribution map and angle-pressure relationship curves. When the pressure reaches a preset threshold, a simulated
intervertebral disc herniation demonstration is triggered. This invention demonstrates the changes in cervical
spine curvature and
intervertebral disc stress under different head-down postures, and is suitable for
medical teaching and
popular science demonstrations.
