Abstract
Using water jets for bone drilling surgery allows the development of flexible instruments for key-hole surgery. Since the heterogeneity of bone causes variations in the drilling depth, a predictive model that describes the drilling depth and maximum dispersion at various jet times was created. Twenty-two holes were drilled in twelve pig thigh-bones (70MPa, 0.4mm nozzle) with jet times of 1, 3 and 5 seconds and measured using microCT-scans. A significant (p<0.001, R2=0.52) correlation was found for predicting the drilling depth: Ldepth= 5.22 x t0,352. Limited depth-variation in drilling times <0.2s allows water jet surgery in open-loop configurations that is used for surgical cartilage repair treatments.
