An interactive method for achieving ergonomically optimum conditions during laparoscopic surgery

Laparoscopy is widely used during living kidney donation, nephrectomy, bariatric surgery, and surgery for gastrointestinal tumors and colorectal cancer. However, laparoscopic surgery requires prolonged use of instruments and has low mechanical efficiency. In addition, to meet specific surgical demands while visualizing the surgical area on the screen, surgical personnel frequently violate the postures proposed by human factor engineering; this naturally results in a physical burden on the personnel. In this study, using laparoscopic nephrectomy as an example, an auxiliary hoisting device for surgery was designed, and pedals from a variety of equipment were integrated into the auxiliary plant. Both entity testing conducted in the hospital and 3D surgical simulation of the auxiliary plant showed that this device could improve compliance with human factor engineering recommendations during laparoscopic surgery and could also promote interaction and tacit understanding between surgical personnel, thereby providing ergonomically optimum conditions during laparoscopy.
