ABSTRACT=<p><bold>Objective:</bold> To compare the operation mode and clinical short-term outcomes of the Micro Hand S and the da Vinci surgical robot, we chose total mesorectal excision (TME) as the standard procedure for its good reflection of robot-assisted surgery advantages.</p><p><bold>Methods:</bold> We collected a total of 54 consecutive patients who underwent robot-assisted TME by two surgical robots from January 2016 to October 2020. We used propensity score matching (PSM) to create balanced cohorts of Micro Hand S group (<italic>n</italic> = 14) and da Vinci group (<italic>n</italic> = 14). Robotic installation and operation time, hospital and surgery costs, and intraoperative and postoperative clinical outcomes were compared.</p><p><bold>Results:</bold> In terms of robotic installation time, the Micro Hand S robot took longer than the da Vinci robot (24.2 ± 9.4 min vs. 17.1 ± 5.1 min, <italic>P</italic> &lt; 0.05). As for the costs, the Micro Hand S group had lower total hospital costs (87,040.1 ± 24,676.9 yuan vs. 125,292.3 ± 17,706.7 yuan, <italic>P</italic> &lt; 0.05) and surgery costs (25,772.3 ± 4,117.0 yuan vs. 46,940.9 ± 10,199.7 yuan, <italic>P</italic> &lt; 0.05) than the da Vinci group. There were no statistically significant differences (<italic>P</italic> &gt; 0.05) in other indicators, including total operation time, robotic operation time, blood loss, time to first liquid diet, time of getting out of bed, and hospital stay.</p><p><bold>Conclusion:</bold> The Micro Hand S enables patients with rectal cancer to enjoy lower medical costs of robotic surgery.</p><p><bold>Clinical Trial Registration:</bold><ext-link ext-link-type="uri" xlink:href="https://ClinicalTrials.gov" xmlns:xlink="http://www.w3.org/1999/xlink">ClinicalTrials.gov</ext-link> [NCT02752698]</p>
