This paper presents details of the development and validation of a measurement system for
laparoscopic surgical procedures. An individual marker set is attached to each surgical
instrument, and hence the developed system can simultaneously track multiple surgical
instruments. The tracked surgical instruments can be exchanged during an operation. The
movements of surgical instruments such as grasping forceps, scissors forceps, clip appliers,
and needle holders are measured, and their tip positions, opening ratios, gripper rotation …

This paper describes the development and validation of measurement system for
laparoscopic surgical procedures in practical surgery training. In order to measure motion of
surgical instruments in a practical surgery training using cadaver or live animal, a motion
capture (MoCap) based simple measurement system is developed. Since this system has
simple configuration and requires only origin definition, it is easy to install in operating room.
By attaching individual marker set to each surgical instrument, this system can track multiple …
