Abstract：
The three-dimension digital image microscope system (3D-DIM) with a better ergonomic design and equipment characteristics can contribute to the achievement of good results during microsurgery. In this study, the safety and efficiency of 3D-DIM assisted varicocelectomy was evaluated. From July 2019 to November 2019, fifteen cases with varicocele (20 sides of varicocele in total) were included, seven cases underwent 3D-DIM-assisted modified microsurgical subinguinal varicocelectomy, and eight cases underwent modified microsurgical subinguinal varicocelectomy under standard operating microscope (SOM). The mean operative time of 3D-DIM group (67 ± 12.3 min) was a little longer than that of SOM group (55 ± 12.9 min) (p < 0.05). There was no significant difference between the two groups in the number of internal spermatic arteries, internal spermatic vein, lymphatics, gubernacular vein, external spermatic vein and post-operation complications. The 3D-DIM showed a significant difference in image definition for nurse (p < 0.01) and in doctor-nurse cooperation (p < 0.05) over SOM. The 3D-DIM with better ergonomic design and image definition can be applied to perform microsurgical subinguinal varicocelectomy, and could improve the surgeon\'s fatigue and doctor-nurse cooperation. We believe that the 3D-DIM would be widely used in the field of male infertility microsurgery in the near future.
摘要：
具有更好的人体工程学设计和设备特性的三维数字图像显微镜系统（3D-DIM）可以有助于在显微手术中取得良好的效果。在这项研究中,评估了3D-DIM辅助精索静脉曲张切除术的安全性和有效性.从2019年7月至2019年11月，包括15例精索静脉曲张（精索静脉曲张共20侧），7例接受了3D-DIM辅助的改良显微外科腹股沟下精索静脉曲张切除术，8例患者在标准手术显微镜（SOM）下接受了改良的显微手术腹股沟下精索静脉曲张切除术。3D-DIM组的平均手术时间（67±12.3min）比SOM组（55±12.9min）稍长（p<0.05）。两组间精索内动脉数目无显著差异,精索内静脉,淋巴管,杯状静脉,精索外静脉和术后并发症。与SOM相比，3D-DIM在护士的图像清晰度（p<0.01）和医生与护士的合作（p<0.05）方面具有显着差异。具有更好的人体工学设计和图像清晰度的3D-DIM可应用于显微外科腹股沟下精索静脉曲张切除术，可以改善外科医生的疲劳和医生-护士的合作。我们相信3D-DIM将在不久的将来广泛应用于男性不育显微外科领域。
