Abstract
AbstractThe use of pulsating water jet as a minimal invasive method for disintegration of bone cement requires optimal determination of its machine settings which effects the erosion depth. The volume of fluid required and the distance of the nozzle from the bone cement surface during its disintegration are one of the important machine settings for its in-vivo applications. Moreover, controlling of the technology during its action without effecting the phenomenon responsible for erosion is a challenging task. Therefore, in this study influence of variation of the nozzle diameter and standoff distance on the disintegration depth have been studied. Acoustic emission signals in form of acceleration values, recorded during the disintegration process are analyzed and correlated with the achieved groove depth trends. The results showed similar trend of acceleration values and disintegration depth when varying the nozzle diameter or standoff distance. Both the acceleration and disintegration depth, increases with an increase in the standoff distance till an optimal limit and decreases after it. Also, with the increase in the nozzle diameter, disintegration depth and acceleration value increase due to increase in the water flow rate. The analogy of recorded acoustic emission signals with the depth values achieved during the process can be used in further studies for controlling of the water jet process.KeywordsPulsating water jetBone cementDisintegration depthOn-line monitoring
