Discovery and Detection of Surgical Activity in Percutaneous Vertebroplasties

Discovery and Detection of Surgical Activity in Percutaneous Vertebroplasties

In medical collaboration with:
Ekkehard Euler
Sandro Michael Heining

Contact Person(s): Ahmad Ahmadi

Keywords: Surgical Workflow, Past Projects


In this project, we aim at discovering automatically the workflow of percutaneous vertebroplasty. The medical framework is quite different from a parallel project , where we analyze laparoscopic surgeries. Contrary to cholecystectomies where much information is provided by the surgical tools and by the endoscopic video, in vertebroplasties and kyphoplasties, we believe that the body and hand movement of the surgeon give a key insight into the surgical activity. Surgical movements like hammering of the trocar into the vertebra or the stirring of cement compounds are indicative of the current workflow phase. The objectives of this project are to acquire the workflow related signals using accelerometers, processing the raw signals and detecting recurrent patterns in order to objectively identify the low-level and high-level workflow of the procedure.
