abstract: "<p>This dataset comprises the data obtained during the technical calibration and preclinical validation of the ShaftFlex, a grasping force feedback providing add-on for laparoscopic graspers.</p><ul><li>The technical calibration was done to accurately map real-time Hall sensor data to grasping force: the file calibration_grasping_force_ShaftFlex.m contains the data of the 2 calibration steps (with force, pressure and Hall sensor measurements) and uses exponential regression to produce a relation between force and Hall sensor output.</li><li>The preclinical validation (randomized controlled trial) was done to measure the influence of grasping force feedback on skill acquisition in laparoscopic skills training: the Excel file force_feedback_grasper_data.xlsx contains the following objective parameter data: time to completion [s], maximum force [F], mean force [F], errors [number of]</li></ul>"
