Robot-assisted sleeve gastrectomy in patients with obesity with a novel Chinese domestic MicroHand SⅡ surgical system

Background: A new member has been added to the Chinese MicroHand surgical robot family, developed based on the successful application of control algorithms. As a benefit of using these specialized control algorithms, the motion mapping relation can be built up without the help of a built-in image system, resulting in a novel Chinese domestic surgical robot with two arms called MicroHand SⅡ, which is different from the former MicroHand S and da Vinci systems. The analysis technique of clinical practise using the Chinese domestic surgical robot to perform sleeve gastrectomy is not well presented. In this study, we investigate the performance of a novel MicroHand SⅡ robotic platform in patients with obesity. Methods: : From March 2018 to April 2019, a total of 7 patients affected by obesity were operated on with the robot-assisted technique using the MicroHand SⅡ surgical system. Data regarding demography, surgical procedure and the 3-month outcome postoperation were collected. Results: : There were 2 female and 5 male patients with a mean age of 34.0±11.4 years. The mean operative time was 166.4 ±16.1 minutes. None were converted to open surgery. All anthropometry indices improved significantly at 3 months postoperatively. Conclusions: : In conclusion, the Chinese domestic robot surgical system MicroHand SⅡ could be feasibly and safely applied in sleeve gastrectomy in patients with obesity. This robotic platform has presented its own obvious advantages.
