Automatic Vibrotactile Device for Interruption of Apnea in Premature Infants

The engineering design of surgical instrumentation to apply mehanical forces and linear moments on the human bones during he operations constitutes a rather difficult task. This is due both to he natural and pathological irregularities of the human bone morhology and surfaces and also to the individual variations from ne patient to another. Usually, the forces are applied by the sureon only on a determined part of the bone surfaces. This paper escribes an innovative computational design method to digialize, simulate, and fit mathematically the anterior vertebral body acet. We used real experimental data from 17 human cadaveric pecimens to get and store a large amount of numerical surface igital values. The complete anterior vertebral body side was viualized and analyzed with grid data Subroutine, which was also sed first to select the so-called natural regions of interest ROIs . hese ROIs correspond to those parts of the surface in contact ith the surgical instrumentation, where the mechanical forces are pplied. Subsequently, a numerical mathematical fitting-model
