Smartphone cameras are continuously improving. The present study aimed to evaluate the possibility of using smartphones' magnification system to perform microanastomosis in rats.
Fifteen rats were randomly divided into 3 groups, according to the magnification system used: Microscope, iPhone 7 smartphone, and Galaxy S7 smartphone. In the microscope group, a DFVasconcelos microsurgery microscope was used. In both smartphone groups, the magnifications systems were connected to a 55-inch television through the mirror function. Animals in both groups underwent femoral artery anastomosis in the right forepaw and femoral nerve neurorrhaphy in the left hindleg. The body weight, arterial and nerve caliber, and anastomosis time and patency were immediately analyzed.
No significant differences were observed between the groups regarding body weight, arterial, or nerve caliber. The smartphones did not provide a sufficient quality of image for an adequate identification of the arterial walls. Therefore, neither arterial anastomosis nor neurorrhaphy could be completed, even after 3 hours of surgery. The first steps toward anastomosis or raffia were performed with difficulty.
The current video resolution and lack of stereoscopic image of available smartphones is not sufficient to perform video-assisted anastomosis of femoral arteries or nerves.
智能手机摄像头在不断改进。本研究旨在评估使用智能手机放大系统在大鼠身上进行显微吻合术的可能性。
根据所使用的放大系统，将15只大鼠随机分为3组：显微镜组、iPhone 7智能手机组和Galaxy S7智能手机组。显微镜组使用DFVasconcelos显微外科显微镜。在两个智能手机组中，放大系统通过镜像功能连接到一台55英寸的电视机。两组动物均在右前爪进行股动脉吻合术，在左后肢进行股神经缝合术。立即分析体重、动脉和神经管径以及吻合时间和通畅情况。
在体重、动脉或神经管径方面，各组之间未观察到显著差异。智能手机无法提供足够质量的图像以充分识别动脉壁。因此，即使经过3小时的手术，动脉吻合术和神经缝合术均无法完成。进行吻合术或神经缝合术的第一步都很困难。
目前可用智能手机的视频分辨率和缺乏立体图像不足以进行股动脉或神经的视频辅助吻合术。
