Background: New robotic handheld systems have been developed to address some of the technical limitations of laparoscopy.
Aim: To perform a kinematic analysis of the surgeon during the use of a novel robotic-driven handheld laparoscopic instrument with ergonomic design in urethrovesical anastomosis on an animal model.
Project Description: Five right-handed experienced surgeons performed an urethrovesical anastomosis on an in vivo porcine model. They used both a conventional and robotic laparoscopic needle holder.The type of instrument (conventional or robotic) to start the procedure was randomly assigned to each surgeon. Inertial Measurement Units (IMUs) were used to estimate the pose of body segments (Xsens, MVN BIOMECH) and the Visual3D software (C-motion Inc) for kinematic analysis.
Preliminary Results: The use of IMUs allowed us to obtain in real time the body segments’ velocity and acceleration with higher accuracy than traditional photogrammetry methods.
