摘要

引言 本研究旨在利用大鼠股血管模型验证机器人显微手术平台的熟练性和准确性。材料和方法 8 名经验少于 5 年的显微外科医生每人进行了 8 次试验(大鼠),其中一半使用机器人,另一半使用人工显微吻合术,共完成了 256 例大鼠股血管手术。对两组的血管人口统计学、熟练程度(缝合持续时间和机器人显微外科技能结构评估(SARMS))和准确性(通畅度和扫描电子显微镜(SEM))进行了分析。结果 使用机器人时,平均需要 4 次试验才能达到吻合总时间和通畅率的高点。每根血管的吻合时间明显增加(第 8 次试验为 34.33 分钟,第 8 次试验为 21.63 分钟,P<0.05)。

Further validating the robotic microsurgery platform through preclinical studies on rat femoral artery and vein.

Introduction This research aims to validate the proficiency and accuracy of the robotic microsurgery platform using rat femoral vessel model. Materials and Methods Total of 256 rat femoral vessels were performed, half using robotic and the other by manual microanastomosis by 8 microsurgeons with less than 5 years of experience given 8 trials (rats) each. Vessel demographics, proficiency (duration of suture and Structured Assessment of Robotic Microsurgical Skills (SARMS)) and accuracy (patency and Scanning Electron Microscopic (SEM)) was analyzed between the two groups. Results Using the robot, an average of 4 trials was needed to reach a plateau in total anastomosis time and patency. Significant more time was required for each vessel anastomosis (34.33 versus 21.63 minutes on the 8th trial, p<0.001) one factor being higher number of sutures compared to the hand-sewn group (artery: 7.86±0.51 versus 5.86±0.67, p=0.035, vein: 12.63±0.49 versus 9.57±0.99, p=0.055). The SARMS scores became nonsignificant between the two group on the 4th trial. The SEM showed higher tendency of unevenly spaced sutures, infolding, tears in the vessel wall for the hand-sewn group. Conclusion Using the robot, similar patency, accuracy, and proficiency can be reached through fast but steep learning process within 4 trials (anastomosis of 8 vessels) as the hand-sewn group. The robotic anastomosis may take longer time, but this is due to the increased number of sutures reflecting higher precision and accuracy. Further insight of precision and accuracy was found through the SEM demonstrating the possibility of the robot to prevent unexpected and unwanted complications.

期刊介绍: The Journal of Reconstructive Microsurgery is a peer-reviewed, indexed journal that provides an international forum for the publication of articles focusing on reconstructive microsurgery and complex reconstructive surgery. The journal was originally established in 1984 for the microsurgical community to publish and share academic papers. The Journal of Reconstructive Microsurgery provides the latest in original research spanning basic laboratory, translational, and clinical investigations. Review papers cover current topics in complex reconstruction and microsurgery. In addition, special sections discuss new technologies, innovations, materials, and significant problem cases. The journal welcomes controversial topics, editorial comments, book reviews, and letters to the Editor, in order to complete the balanced spectrum of information available in the Journal of Reconstructive Microsurgery. All articles undergo stringent peer review by international experts in the specialty.
