ShaftFlex technical and pre-clinical validation data

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.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.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]本数据集涵盖ShaftFlex（适配腹腔镜抓取器的抓取力反馈加装套件）的技术校准与临床前验证阶段所采集的数据。本次技术校准旨在实现实时霍尔（Hall）传感器数据与抓取力的精准映射：文件calibration_grasping_force_ShaftFlex.m包含2次校准步骤的采集数据（涵盖力、压强与霍尔传感器测量值），并通过指数回归算法推导出力与霍尔传感器输出间的对应关系。本次临床前验证（随机对照试验）旨在评估抓取力反馈对腹腔镜技能训练中技能习得的影响：Excel文件force_feedback_grasper_data.xlsx包含以下客观参数数据：完成时长[单位：秒，s]、最大力[F]、平均力[F]、失误数量
