  1. Usability test with neurosurgeons. The usability test with neurosurgeons was performed to validate multiple customer requirements in terms of the performance and the ergonomics of SQ.line® KERRISON. The test was performed with 12 neurosurgeons within a simulated clinical environment. The performance and the ergonomic properties were rated positive.
  2. Handle comfort evaluation report. The SQ.line® KERRISON handle was compared in terms of comfort during use to its predecessor and one of its competitor’s handle. It is based on the visualization of prevailing surface pressure distributions during the actuation by means of pressure measuring foil. The SQ.line® KERRISON showed smaller areas of high surface pressure and a more homogeneous pressure distribution.
  3. Gloss value measurement. The gloss values of two new and five aged SQ.line® KERRISONs were measured on three defined areas from two different angles each. The results were compared to the values of uncoated Aesculap KERRISONs. The processing had no significant influence on the reflection behavior. The Noir® plus coating reduced reflections on the slider by 70% to 86%, on the main part by 47% to 63% and on the handle by 19% to 76% depending on the direction of measurement.
  4. Jamming test. Five samples of three different SQ.line® KERRISONs and previous Aesculap KERRISONs were tested on lamb spine with 50 repeated punches. The SQ.line® KERRISON showed no jamming for the duration of the test.
  5. Usability test with CSSD and OR personnel. The usability test with CSSD and OR personnel was performed to validate multiple customer requirements in terms of the reprocessing and handling of the upwards cutting SQ.line® KERRISON. Ten people with an average CSSD experience of more then five years where interviewed. The suitability for reprocessing and the handling were rated positive.
