This apparatus is adapted for replaceable implantation in soft body tissues for the measurement of the mechanical behavior of the soft tissues of the body. The apparatus consists of a thin walled tube with a piezo-resistive strain gauge element bonded to its walls. Tension in tissue fiber bundles results in a squeezing pressure against the sides of the tube, which produces a change in the shape of the tube and thus a change in the resistance of the strain gauge element. This resistance change is then measured and displayed. A method of inserting and removing the apparatus is also described, as are several techniques for calibration. |
