Task and crisis analysis during surgical training

Purpose   To design a surgical training environment based on task and crisis analysis of the surgical workflow.Method   The environment consists of: (1) real surgical instruments that are augmented with realistic haptic feedback and VR capabilities, (2) human sensory channels such as tactile, auditory and visual in real time, and (3) the ability to facilitate deliberate exposure to adverse events enabling mediation of error recovery strategies.Validation   Five surgeons were immersed in our medical simulation environment through task and crisis scenarios of a typical vertebroplasty workflow.Results   Based on a five-point Likert-scale survey, the face validity of our simulation environment was confirmed by investigating surgeon behavior and workflow response.Conclusions   The result of the conducted user-study corroborates our unique medical simulation concept of combining VR and human multisensory responses into surgical workflow.
