Hysteresis data, residual force and haptic sensitivity data

The dataset 'sensitivityThreshold(haptic feedback).zip' contains the results of a haptic feedback sensitivity study comparing a novel laparoscopic grasper with 2 conventional graspers. Also grip preference of each participant was stored.The instrument sensitivity was validated by measuring the level at which participants could discriminate force differences applied at the grasper tip with an increasing force level, while the subjects were holding the new instrument and a conventional grasper at the handle grip. The force was increased and subjects reported at which force level they were able to feel an increase. The dataset 'balancingError.zip' consists of 10 repetitions of measurements on a balanced compliant laparoscopic grasper. It is the instrument's unloaded residual balancing error measured on a linear stage with load cell.

数据集"sensitivityThreshold(触觉反馈（haptic feedback）).zip"包含一项触觉反馈敏感度研究的实验结果，该研究对比了一款新型腹腔镜抓钳与两款传统腹腔镜抓钳的性能，同时存储了每位受试者的握持偏好数据。本研究通过如下流程验证器械的敏感度：令受试者分别握持新型手术器械与传统腹腔镜抓钳的手柄，逐步递增施加于抓钳钳头的力，测量受试者可分辨该力变化的临界力值；受试者需报告自身首次感知到力的提升时对应的力级。数据集"balancingError.zip"包含对一款平衡型柔顺腹腔镜抓钳的10次重复测量结果，该测量为在搭载测力传感器的线性位移平台上测得的该器械的空载残余平衡误差。
