Sensitive silicon piezoresistive measuring nerve-root retractor
Retractor is a product of applied research project L3-0309 Piezoresistive Force Sensors for controlled spinal nerve root retraction in lumbar disc surgery – a new surgical instrument for prevention of intraoperative root traction injury performed in collaboration between University Medical Centre Ljubljana, Department of Neurosurgery and University of Ljubljana, Faculty of Electrical Engineering, LMSE;
Funded by: Ministry of Health and Ministry of Higher Education, Science and Technology of Republic of Slovenia
Head of project: prof.dr.Roman Bošnjak, University Hospital Center, Department of Neurosurgery, Zaloska 7, 1000 Ljubljana, Slovenia:
