Simulating laser ablation for minimal invasive surgery of bone

Background: Musculoskeletal diseases affect millions of people in ageing societies world wide. Modern treatment strategies heavily rely on minimal invasive access procedures which may exploit laser based dissection techniques. Likewise, laser ablation is used to prepare micron sized biopsies that, in turn, inform the development of new treatment technologies. However, little is know about the heat impact on the material during the ablation process.

Project: Therefore, this project aims at investigating the heat impact during pulsed laser ablation and key tasks include

(i) develop a finite element based evaluation of the heat impact of a pulsed laser on bones extra-cellular matrix
(ii) use this model to identify a set of admissible operating parameters that do not damage the material

Impact: If successful, this project will inform minimal invasive surgery technologies. In addition, the results will have direct, positive impact on state of the art preparation technologies used in different laboratories at Heriot-Watt University and help to improve its research performance.
