Summary
Novice surgeons often worry about the lack of haptic feedback (HF) in robotic surgery. However, with increased experience, the perception of HF and comfort levels rise, suggesting its importance may be overestimated.
Area of Science:
- Robotic Surgery
- Surgical Simulation
- Human-Computer Interaction
Background:
- The absence of haptic feedback (HF) is a significant concern for surgeons new to robotic procedures.
- Enhanced visual cues in robotic surgery might mitigate the perceived need for HF.
Purpose of the Study:
- To investigate the perception of HF among surgeons with varying levels of robotic surgery experience.
- To assess the impact of HF absence on surgeon comfort and identify any HF-related complications.
Main Methods:
- A survey of 52 individuals assessing HF perception, missed HF, and discomfort during robotic surgery.
- Participants included surgical novices, intermediate laparoscopic surgeons, and experienced robotic surgeons.
- Visual analog scales were used for subjective assessments, and experienced surgeons reported on complications.
Main Results:
- Perception of HF increased with experience, from 50% in novices to 100% in experts (p < 0.05).
- Discomfort due to lack of HF decreased significantly with experience (4.0 in novices vs. 2.6 in experts).
- One complication was reported by an expert surgeon attributed to the lack of HF.
Conclusions:
- Surgeons, even beginners, develop a perception of HF during robotic surgery.
- Increased experience enhances HF perception and comfort, indicating that the importance of "real" HF may be overestimated by novices.
