Impact of navigated‐control assistance on performance, workload and situation awareness of experienced surgeons performing a simulated mastoidectomy

Abstract

The results demonstrate the potential of NC support in terms of lower workload and enhanced patient safety. Cost effects might be reduced by remodelling the control function.

Envisioning robotic surgery: Surgeons' needs and views on interacting with future technologies and interfaces

“…37 In addition, interruptions in the surgeon's workflow caused by the technological implementation have been addressed. 29 The learning curve in robotic surgery varies, depending on the complexity of the procedures and on the surgeon's experience of similar technology and familiarity with the procedure in question. 22 In recent work, it was suggested that the minimal training before patient-related console time should involve live and video observations and should confer knowledge, table assistance and basic skills.…”

“…Leaving virtual landmarks on the image (#19 in Table 2) could serve several functions. In addition to helping surgeons orient and navigate (cf image-guided navigation 29,37 ), the surgeons saw potential in marking areas where extra caution is needed (cf 'no-go' zones 5,9,11,12,18,34 ; #11 in Table 2). The use of markers in a 3D environment for realigning the robotic instruments has already been suggested.…”

“…In this paper, the operation outcome is considered from the potential of the technologies in the surgeons' eyes; discussion on actual patients' outcomes is excluded (see, e.g., Ahmed et al . and Luz et al …”

“…reported improvements in performance and patient safety – at the cost of increased time pressure and mental workload for inexperienced surgeons – but there were differences between surgeons in reactions when the information from the navigation system conflicted with their own assessment of the situation . In addition, interruptions in the surgeon's workflow caused by the technological implementation have been addressed …”

“…In the case of prostatectomy, operation outcome depends principally on the removal of all cancerous tissue and secondarily on post-surgery complications and how well the nerves and other important structures that affect erectile and urinary functions are preserved. 28 In this paper, the operation outcome is considered from the potential of the technologies in the surgeons' eyes; discussion on actual patients' outcomes is excluded (see, e.g., Ahmed et al 3 and Luz et al 29 ). In examining the second angle, user experience, we refer to good human-robot interaction with regard to usability, user feedback and interfaces, immersion, physical and cognitive ergonomics, communication in the operating theatre and comfort.…”
