Impact of a motorised articulated laparoscopic needle holder with ergonomic handle on the gesture smoothness: a pilot study

Résumé

Purpose: The objective of this study is to assess the smoothness of a laparoscopic gesture performed with a motorised articulated instrument in comparison with a conventional one. Methods: One right-handed laparoscopic expert surgeon has been recruited for this study. He performed ten vesicourethral anastomoses, in a pelvic stand, using two kinds of laparoscopic instruments (standard and motorised) for different operating room conditions, especially table height adjustments. A 3-axis accelerometer and cameras are used to record information on the dominant upper limb motions during the tasks. Results: Two different methods are applied in order to evaluate the gesture smoothness. Both are using the acceleration data of the elbow collected during the surgical procedure. The first method uses the first-order derivative of the acceleration and is called log dimensionless jerk. The second one is based on the acceleration's Fourier spectrum and is called SPARC. For similar surgical trials of 2.5 stitches, the two methods tend to show that the gesture smoothness is globally improved by using the motorised articulated laparoscopic needle-holder. Conclusions: These preliminary results give a first indication on the benefit of the motorisations and articulations of a surgical instrument on the gesture performance. They have to be validated with more trials.
