title: Assessing cognitive & motor performance in minimally invasive surgery (MIS) for training & tool design.
abstract: The objective of this paper is to present the development of a new modelling diagram (MCMD) to represent MIS procedures in terms of both motor and cognitive actions. Through observation and analysis of several laparoscopic cholecystectomy procedures and based on task analysis techniques, we created a diagram language composed of six primary symbols: processes, decisions, interrupt service routines (ISRs), options points and AND and OR gates. We then tested and refined them during 10 new cases until no further changes seemed necessary, we have since applied this approach to 6 laparoscopic colorectal surgeries and have found that no further symbols were necessary though the procedural representation was naturally different. This modelling diagram allowed us to represent both cognitive and motor performance aspects of surgical procedures in a unified framework and will in future allow us to assess motor performance on particular surgical tasks at particular points in the procedure (i.e., the surgical context).
