Abstract：
BACKGROUND: Free flap surgery is inconvenient because an attending physician must observe a patient\'s condition every day to ensure that normal tissue is restored within 72 h after the surgery. To address this problem, this paper proposes a remote monitoring technology to observe a patient\'s condition in real time.
METHODS: To design a monitoring system, the camera consists of MCU board, DC-DC converter, alarm performance, Wi-fil module, and server, and the camera and MCU part is connected to the server through the wi-fi network. A camera obtains the images of the surgical site once every 2 s, and the images are transmitted to the attending physician or nurse via Wi-Fi communication. The working distance between camera and surgical site is 56 cm, and the viewing angle of a camera is 60° (radius).
RESULTS: A video shooting test is also performed, in which the images are obtained once per hour between 17:00 and 08:00 the next day; the results show that high-quality images are obtained in the video shooting test. The imaging error is zero (0 GB) in the video shooting test results.
CONCLUSIONS: The imaging of the surgical site can be obtained by camera system, and the proposed method is that there no storage error occurs during the shooting process. In addition, the shooting performance has high velocity. It is possible to control the WD according to a patient\'s body via a holding manipulator used for the camera. The new method is expected to be used for remote patient management, for a wide range of procedures, in the medical field.

摘要：
背景：游离皮瓣手术不方便，因为主治医师必须每天观察患者的病情，以确保在手术后72小时内恢复正常组织。为了解决这个问题,本文提出了一种实时观察病人病情的远程监控技术。
方法：要设计监控系统，相机由MCU板组成，DC-DC转换器，报警性能,Wi-fil模块,和服务器，摄像机和MCU部分通过wi-fi网络与服务器相连。一台摄像机每2秒获取一次手术部位的图像，图像通过Wi-Fi通信传输给主治医师或护士。摄像机与手术部位之间的工作距离为56厘米，相机的视角为60°(半径)。
结果：还进行了视频拍摄测试，其中在17:00至次日08:00之间每小时获取一次图像；结果表明，在视频拍摄测试中获得了高质量的图像。在视频拍摄测试结果中,成像误差为零(0GB)。
结论：手术部位的成像可以通过摄像机系统获得，所提出的方法是在拍摄过程中不发生存储错误。此外,射击性能具有很高的速度。可以经由用于相机的保持操纵器根据患者的身体来控制WD。新方法有望用于远程患者管理，对于广泛的程序，在医疗领域。
