最佳视力和人体工程学是显微外科手术取得良好效果的重要因素。三维(3D)数字图像显微镜系统具有更好的3D景深，可以缓解外科医生颈部和背部的压力，从而改善显微外科手术的效果。我们报道了一项使用3D数字图像显微镜系统(3D-DIM)对大鼠进行的一项随机前瞻性研究：附睾术和输精管吻合术。成年雄性大鼠16只，随机分为标准手术显微镜(SOM)组和3D-DIM组，每组8只。测量的结果包括手术时间、术后实时机械通畅率和吻合口漏。此外，还设计了用户友好的显微镜评分，以评估显微镜的人体工学设计和设备特性。两组手术时间差异无统计学意义。两组术后实时机械通畅率均为100.0%。SOM组和3D-DIM组吻合口瘘发生率分别为16.7%和25.0%，两组均未发现吻合口瘘。在人体工学设计方面，3D-DIM组根据外科医生的感受获得了更好的分数；在设备特性方面，3D-DIM组的清晰度得分较低，灵活性和适应性得分较高。基于我们在大鼠模型上的随机前瞻性研究，我们认为3D-DIM在男性不育重建显微手术中可以在不影响结果的情况下提高外科医生的舒适度，因此3D-DIM可能会在未来得到广泛的应用。
Optimal vision and ergonomics are essential factors contributing to the achievement of good results during microsurgery. The three-dimensional (3D) digital image microscope system with a better 3D depth of field can release strain on the surgeon's neck and back, which can improve outcomes in microsurgery. We report a randomized prospective study of vasoepididymostomy and vasovasostomy using a 3D digital image microscope system (3D-DIM) in rats. A total of 16 adult male rats were randomly divided into two groups of 8 each: the standard operating microscope (SOM) group and the 3D-DIM group. The outcomes measured included the operative time, real-time postoperative mechanical patency, and anastomosis leakage. Furthermore, a user-friendly microscope score was designed to evaluate the ergonomic design and equipment characteristics of the microscope. There were no differences in operative time between the two groups. The real-time postoperative mechanical patency rates were 100.0% for both groups. The percentage of vasoepididymostomy anastomosis leakage was 16.7% in the SOM group and 25.0% in the 3D-DIM group; however, no vasovasostomy anastomosis leakage was found in either group. In terms of the ergonomic design, the 3D-DIM group obtained better scores based on the surgeon's feelings; in terms of the equipment characteristics, the 3D-DIM group had lower scores for clarity and higher scores for flexibility and adaptivity. Based on our randomized prospective study in a rat model, we believe that the 3D-DIM can improve surgeon comfort without compromising outcomes in male infertility reconstructive microsurgery, so the 3D-DIM might be widely used in the future.
