“…The research of surgical robots has gradually become a hot issues. New robotics technologies are emerging [15], such as the Invendoscopy E200 system, Flex® robot system, Senhance, Auris robotic endoscope system, and "Micro Hand S" surgical robot [10,16]. The results of this study showed no statistically significant difference was observed in baseline characteristics between RG and LG groups, so clinical outcomes of these two groups could be compared.…”

Background Expensive cost of surgery has limited the use of surgical robot in China. The emergence of “Micro Hand S” surgical robot provides more choices for surgical treatment. Our study was to evaluate the safety and feasibility of “Micro Hand S” surgical robotic gastrectomy for gastric cancer. Methods Perioperative data of 75 patients who underwent “Micro Hand S” surgical robotic gastrectomy (RG) or laparoscopic gastrectomy (LG) at the Department of General Surgery, Third Xiangya Hospital, Central South University from June 2017 to January 2019 were collected to compare the short-term outcomes between the two groups. Results No statistically significant difference was found in baseline characteristics between the two groups (P > 0.05). RG group had longer operation time (P < 0.01). The harvested lymph nodes were comparable between the two groups (P = 0.084). There were five positive margins in the LG group, and the R0 resection rate was comparable between the two groups (P = 0.247). 16 complications occurred in the RG group according to the Clavien-Dindo classification system, 6 in grade I, and 10 in grade II. 68 complications happened in the LG group, 22 in grade I, 44 in grade II, 1 in grade IIIa and 1 in grade IVa. The comprehensive complications index (CCI) was similar between the two groups (P = 0.895). Intraoperative blood loss, surgical resection, reconstruction of the digestive tract intraoperative blood transfusion, Chemoradiotherapy, pathological type, degree of differentiation, proximal resection margin, time of first flatus, time of liquid diet, time of abdominal drainage tube extraction, and hospital stay for RG and LG were similar too (P > 0.05). Conclusion “Micro Hand S” surgical robotic gastrectomy is safe and feasible. Keywords Surgical robot; Gastric cancer; Gastrectomy; Safety; Feasibility

Background As the first domestically produced Chinese surgical robot for clinical use, the Micro Hand S robot has been applied to total mesorectal excision (TME) for rectal cancer in our center since 2017. The aim of this study was to evaluate the safety and feasibility of the Micro Hand S robot-assisted TME (R-TME) in comparison with laparoscopic TME (L-TME).Methods Between May 2017 and February 2018, patients who underwent R-TME and L-TME in the Third Xiangya Hospital were prospectively included in this study. The data including intraoperative outcomes, postoperative outcomes, pathological outcomes, and functional outcomes were analyzed and compared.Results Totally, 30 patients underwent L-TME and 21 patients underwent R-TME. The patient characteristics of the two groups were similar. Regarding intraoperative and postoperative outcomes, the R-TME group had significantly less blood loss (95.2 vs. 130.0 ml, p = 0.022), shorter time to first flatus (2.1 vs. 2.9 d, p = 0.017) and first liquid intake (2.8 vs. 3.7 d, p = 0.027) than the L-TME group. There were no significant difference in the operative time, conversion, protective ileostomy, length of hospital stay, pain score, complications, and 30-day mortality between the two groups (p > 0.05). In addition, the pathological and functional outcomes also did not differ significantly.Conclusion The Micro Hand S robot-assisted total mesorectal excision is safe and feasible for rectal cancer. However, prospective and large sample size trials are needed to further confirm this conclusion.Trial registration:Clinicaltrial.gov, NCT02752698, Registered on 27 April 2016, https://clinicaltrials.gov/ct2/show/study/NCT02752698?term=Micro+hand&cntry=CN&draw=2&rank=1

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.
