A recent study led by Arsham Hamidi, entitled “Multimodal Feedback Systems for Smart Laser Osteotomy: Depth Control and Tissue Differentiation,” focuses on the development of a multimodal feedback system to achieve an accurate and safe surgery procedure.
The study, published in Lasers in Surgery and Medicine (LSM), the official journal of the American Society for Laser Medicine and Surgery, Inc. (ASLMS), was selected as the November 2023 Editor’s Choice.
Testing on pig femur bone specimens showed successful tissue differentiation and depth feedback without observable thermal damage or carbonization.
“The developed multimodal feedback system exhibited high accuracy in tissue differentiation and depth control, indicating its potential for enhancing minimally invasive surgery,” Hamidi said. “The system demonstrated promising results in improving the safety and accuracy of laser surgery. This integrated approach warrants further research and development.”

About the Study
Optical feedback systems were incorporated with an Er:YAG laser to enhance the safety and precision of laser osteotomy (bone surgery). The feedback systems included a real-time visual monitoring system for controlling the depth of laser cuts and a tissue sensor that distinguished between different tissue types based on their chemical composition.Testing on pig femur bone specimens showed successful tissue differentiation and depth feedback without observable thermal damage or carbonization.
