摘要现代化水平的不断进步和医疗水平发展，眼科的手术已经进入显微手术时代。手术显微镜主要是用于显微外科手术，医生在一些比较特殊的手术中，人眼不能直接观察一些细微的病灶，必须借助于显微外科显微镜，在一定的放大分辨率的情况下才能完成手术。目前，手术显微镜成为了一种比较常规的医疗设备。51244

做眼科手术时要求在显微镜下有一定的操作空间，同时视野宽广，使医生能在显微镜下进行精密操作。同时，要求X-Y移动器能够平稳移动，支撑手术臂并能够较快捷精确的移动到手术位置，医生方便的进行眼科手术。

无论何种形式的手术显微镜，均包括光学显微镜系统、照明系统、安装系统和调节系统四部分。本文主要对调节系统中的X-Y移动系统进行设计，一般通过脚踏开关控制，使显微镜做前后左右移动，保持显微镜镜身在手术视野中心，水平X-Y移动装置则可将显微镜精确定位于所需要的位置 。X-Y 平面移动器这种自动化的功能都极大的方便了手术的进行，定位准确而且操作方便。

对于X-Y水平移动器的设计，本文主要介绍传动丝杆机构和直线导轨机构以及电机的选取。

Abstract The level of modernization level of continued progress and development of medical, ophthalmic surgery has entered the era of micro-surgery. Surgical microscope is mainly used for micro-surgery, the doctor some special operation, the human eye can not directly observe some subtle lesions must be by means microsurgical microscope, in certain cases, the resolution can be enlarged complete surgery . Currently, surgical microscope has become a more conventional medical devices.

When requested to do eye surgery under the microscope have some room for maneuver, while broad vision, so that doctors can operate under a microscope for precision. At the same time, requiring XY mover can move smoothly, the support arm and the surgery can be more efficient to move to the exact location of surgery, doctors convenient for ophthalmic surgery.

No matter what form of surgical microscope, includes an optical microscope system, lighting system, install the system and regulation systems in four parts. This paper focuses on the aspect regulating system mobile system - (XY Mobile Systems) for the design, usually controlled by a foot switch, so that the microscope do move around, to keep the body in the operative field microscope lens center, the mobile device can be horizontal XY microscope precise definition in the desired position. XY plane mover such automated features greatly facilitate the conduct of the operation, accurate positioning and easy operation.

For the XY horizontal mover design, this article introduces the drive screw mechanism and linear guide mechanism and the motor selection.

Keywords: Surgical microscope; X-Y movement; Regulating device
