Standardised documentation of instrument use during laparoscopic surgery

Zickerow, Matthias; Holmer, Christoph; Kraft, Marc

To date, usability problems for laparoscopic instruments have mainly been investigated using questionnaires or laboratory studies. However, this methodology prevents the duration and frequency of instrument use from being documented objectively. Therefore, a tablet was used to create a graphic user interface which enables instrument use by operating and assisting surgeons to be documented with a high level of temporal precision. In a preliminary study, instrument use was documented for five laparoscopic operations (0:44h-6:01h). 2021 actions and 221 changes of instruments were documented. The longest uninterrupted usage period without changing hands was determined for grasping forceps at 97 min.
