Surgical lighting in motion: Design and validation of an improved suspension mechanism for the surgical luminaire

Usability issues have been observed in luminaire repositioning, during surgical operations. These difficulties were confirmed to be related to the kinematics of the translational subsystem of the suspension mechanism, specifically the possibility of singularity. Due to which the required force for luminaire repositioning depends on the spatial...

Collecting Relevant Environmental Parameters for Surgical Lighting Control

During the surgery, the lighting unit often needs to be manually adapted. However, the manual manipulation may cause loss of concentration, loss of time and increased risk of infections. To improve the manipulation, a semi-automated lighting system commanded by the surgeon is suggested. The commands are given via a pointer device to indicate the...

The surgical lighting problem: ‘Manipulation problems with the surgical lighting system during surgical procedures’

Ergonomic problems of surgical lighting systems have been indicated by surgeons; however, the underlying causes are not clear. The aim of this dissertation is to assess the problems in detail, and subsequently clarify the underlying causes. In the first stage of the research, the observation method was used to quantify the luminaire use during...
