Abstract

Microsurgical skills of trainee surgeons have been subjectively evaluated due to the lack of technological tools. The objective of this investigation is to present the construct validity of the mitracks3D, which is a system designed to help in the objective evaluation of microsurgery trainees. To achieve this, a stereoscopic vision system records the 3D motion of two tweezers manipulated by surgeons during microsurgery training. Using motion analysis parameters (MAPs), quantitative information about their microsurgical skills and performance is obtained. For validation, 14 participants were enrolled and divided into two groups: expert microsurgeons (3 female, 2 male) and trainee surgeons (4 female, 5 male). The 3D motion tracking was acquired while the surgeons practiced with two training models: transferring objects and suture. Twelve MAPs were used to objective assessment the skill levels of each participant. Subsequent, statistical analysis was computed to compare the scores of both groups. Validation results showed statistically significant differences in 8 of the 12 MAPs and in 10 of the 12 MAPs using the transferring and the suturing models, respectively. The capability of mitracks3D to differentiate the performance of microsurgeons by analyzing their movements was shown. The mitracks3D system was successfully validated. With this system was possible to differentiate the psychomotor microsurgical skills between the two groups of surgeons. The mitracks3D system is a suitable device for the evaluation of microsurgical skills in a variety of surgical specialties that require it during the training of their residents.
