Benefits of robotic surgery 2
PLEASE SCROLL DOWN FOR TEXT
AbstractBackground. Research has demonstrated the benefits of robotic surgery for the patient;however, research examining the benefits of robotic technology for the surgeon is limited.This study aimed to adopt validated measures of workload, mental effort, and gaze control to assess the benefits of robotic surgery for the surgeon. We predicted that the performance of surgical training tasks on a surgical robot would require lower investments of workload and mental effort, and would be accompanied by greater gaze control and better performance, when compared to conventional laparoscopy.Methods. Thirty-two surgeons performed two trials on a ball pick-and-drop task and a rope threading task on both robotic and laparoscopic systems. Measures of workload (The SurgeryTask Load Index [SURG-TLX]), mental effort (subjective: Rating Scale for Mental Effort[RSME] and objective: standard deviation of beat-to-beat intervals [SDNN]), gaze control (using a mobile eye movement recorder), and task performance (completion time and number of errors) were recorded.Results. As expected, surgeons performed both tasks more quickly and accurately (with fewer errors) on the robotic system. Self-reported measures of workload and mental effort were significantly lower on the robotic system compared to the laparoscopic system.Similarly, an object...
