NCT04855448

Brief Summary

Central South University in collaboration with Tianjin University developed the first domestically produced Chinese minimally invasive surgical (MIS) robot system which named "Micro Hand S" in 2013. This new MIS robot had been authorized to enter the clinical trial stage by the Ethics Committee of the Third Xiangya Hospital at Central South University. The Micro Hand S robot is safe and feasible in the preliminary study. However, the learning curve in low anterior resection for rectal resection with the Micro Hand S robot are unclear and whether the two surgical robots (Micro Hand S and da Vinci) shared a similar learning curve and the two robot can be trained simultaneously. Therefore, the investigators conduct this retrospective study to focus on this concern.
