Ergonomic Enhancements for Laparoscopic Surgery Using Surgical Platforms

Charles B Becker, BS, MEM, J Scott Roth, MD. University of Kentucky College of Medicine. Introduction. Traditionally, the operating room environment requires the surgeon to stand adjacent to an operating room table. Although this interface was suitable for open operations, the dynamics of laparoscopic surgery may require alternative solutions. Surgical platforms are apparatuses designed to […]

ETrack: An Affordable Ergonomic Assessment Tool for Surgical Settings

Timothy R Coles, PhD, Caroline G Cao, PhD, Cedric Dumas, PhD. Commonwealth of Scientific and Industrial Research Organisation, Wright State University.  Introduction Ergonomic assessment for surgeons and evidence based medical simulation are increasingly recognized as enablers for more productive and safer clinical operations. These can be performed by gathering in-depth information about practitioner’s interactions within […]

Evaluation of eye & hand fatigue in 3D vs. 2D display systems for surgical novices during laparoscopic suturing; a Randomised Control Trial

Adham Youssef, Walid Elbakbak, Amina Bouhelal, Bijen Patel. Queen Mary, University of London. Background: The available data reports the efficacy of the 3D vision system and its superiority to 2D. However the physiological effect of 3D on surgeons remains unaddressed. Aims: We aimed to objectively investigate the effect of 3D on ocular and hand muscles […]
