Objective:Safety and certainty are important when performing minimally invasive cardiac surgery (MICS). To clarify the skills and goals to be acquired, we developed a three-dimensional (3D) surgical motion analysis system for MICS and researched quantification and evaluation of MICS skills. Methods:This system was developed at Keio University and JSR Corporation (JKiC: JSR/Keio University Medical and Chemical Innovation Center, Tokyo, Japan). The basic technology of this system is to attach a cube marker with a QR code to the end of the forceps used for MICS surgery, track the QR code with one camera to obtain a 3D view, and acquire the movement and trajectory of 3D forceps. Actual skill data (10 experts, 40 trainees) were collected. This system was designed using an algorithm that correlates the traditional evaluation method scored by two experts and the scoring method of this system. Results:As preliminary results, we collected data on hand shake; coordination, efficiency, and stability of left- and right-hand movements; and procedure time. Conclusions:This research has made it possible to quantify surgical skills and establish a surgical operation analysis system with algorithms that correlate with traditional assessment methods. In addition, we plan to introduce a new indicator for the protection of the organs. In the future, we would like to improve the accuracy of analytical data by collecting more operational data.
