title: Domestically produced Chinese minimally invasive surgical robot system "Micro Hand S" is applied to clinical surgery preliminarily in China.
abstract: To develop and validate one low-cost and easy-use domestically produced Chinese minimally invasive surgical robot system "Micro Hand S" that surgeons can use to resolve the complicated surgeries challenge.
  
  
  
  From April 2014 to April 2015, one patient with gastric perforation, three patients with acute appendicitis, five patients with acute cholecystitis, and one patient with right colon cancer underwent robotic-assisted surgeries. Eight of these patients were followed for 1 month, and pre- and postoperative changes in blood route test and hepatorenal function examination, surgery duration, hospital stay, total robotic setup time, total robotic operation time, intraoperative blood loss, total postoperative drainage amount, duration of bearing drainage tubes were recorded. Two patients withdrew from the study because of individual privacies.
  
  
  
  We accomplished surgical procedures using "Micro Hand S." No intraoperative complications or technical problems were encountered. All patients recovered and discharged from hospital without complications.
  
  
  
  The domestic surgical robot system "Micro Hand S" was validated as safe and effective through these clinical cases. The proposed design method is an effective way to make "Micro Hand S" become low-cost and easy-use robot system.
