Salient haptic skills trainer: initial validation of a novel simulator for training force-based laparoscopic surgical skills

Abstract

The novel, salient haptic skills simulator improved the precision and accuracy of participants when applying forces with the simulator. These results suggest that the simulator may be a viable tool for laparoscopic force skill training. However, further work must be undertaken to establish full validity. Nevertheless, this work presents important results toward addressing simulator-based force-skills training specifically and surgical skills training in general.

A Novel Craniotomy Simulator Provides a Validated Method to Enhance Education in the Management of Traumatic Brain Injury

“…These include construct, face, and content validation techniques. 18,19 Within the general surgery literature, these mechanisms for validating haptic simulators, 20,21 virtual reality devices, 22 and physical models have laid the groundwork for implementing these tools in surgical training programs. The neurosurgical trauma simulation course described here aimed to validate the craniotomy simulator as a useful training tool.…”

Face and Construct Validity of a Novel Virtual Reality–Based Bimanual Laparoscopic Force-Skills Trainer With Haptics Feedback

“…Previous studies on objective force skills assessment have mainly analyzed unimanual (ie, single-handed) laparoscopic force-based performance but not bimanual performance. 20-22 A few other studies that incorporated bimanual tasks did not effectively analyze the effect of handedness on force skills. 23-25 As hand dominance is found to affect the performance of surgeons and residents, 26 it is highly important to analyze the effect of handedness on bimanual force-based skills.…”

Haptic Feedback, Force Feedback, and Force-Sensing in Simulation Training for Laparoscopy: A Systematic Overview

“…This represents the absolute abdominal force in the left and the right trocar Newton Horeman et al 76 SP maximum abdominal force The absolute abdominal force in the single-port trocar Newton Horeman et al 76 A total of 7 studies have investigated visual force feedback systems. 10,12,20,24,78,83,84 These systems provide feedback either real time, during the task, or after having finished the task. Both methods have had positive effects on training results.…”

“…12 A simulator equipped with visual force feedback significantly improves precision and accuracy of force application by combining real-time visual feedback after practicing specifically designed tasks. 10,24,83 Instead of visual feedback, Wottawa et al have investigated the effect of enhanced tactile feedback. BTs already contain natural haptic feedbacks, therefore the tactile feedback signal consisted of an enhanced sensation transmitted to the handle grip using a specially designed laparoscopic grasper.…”
