The invention relates to the technical field of medical equipment, especially an operation microscope base for clinical department of general surgery. The universal wheel can rotate relative to the base of the base. The inner part of the base body is located at the bottom of the bracket to connect the first rotating shaft, the pull rod is fixed to the first rotating shaft, and the pull rod is located symmetrically at the connecting place of the first rotating shaft. At the end of the bar, the two ends of the bar are fixed with a rotating hole and a pulling hole. The bottom of the base is fixed with a counterweight slot, and the four corners of the weight block are fixed with a fixed hole. The universal wheel is composed of a mounting seat, a fixed frame and a wheel. The wheel is connected to the fixing frame through a screw, and a fixture is set on the screw, and the universal wheel is fixed through the mounting seat. At the bottom of the equipment, the fixed frame is rotatably fixed at the bottom of the mounting seat in the vertical direction through a middle heart pit nail, and the support includes two support plates, both upper and lower, arranged in parallel. The upper and lower support plates are connected by a vertical column, and the surface area of the upper support plate is less than the surface area of the lower support plate. One

本专利技术涉及医疗器械
,尤其是一种临床普外科用手术显微镜底座。
技术介绍
在手术显微镜例如眼科手术显微镜中,手术显微镜支架用于支承不同配置和重量的显微镜头部。带有落地式支架的手术显微镜借助于位于支架底端的底座搁置在地面上。在底座上设置有脚轮以方便移动整个手术显微镜支架并改变其在地面上的相对位置。为了平衡不同配置的显微镜头部的不同重量,要求底座的重量能根据需要而改变。现有的手术显微镜支架中,通过增减附加配重来调节所需的底座重量。在显微镜头部相对较重时,增设配重可以提高支架的倾翻阻力,从而防止整个支架倾翻。例如,当某种配置的显微镜头部重量相对较轻时,也可以去掉或省去一些附加配重,同样也意味着该显微镜用户不必购买过多的配重块,从而可以节省采购成本。现有技术中已经公开了具有可变重量的底座结构,例如专利文献WO2013/143656A2公开了一种支架底座,包括:支架底座主体,该支架底座主体可以设计成能够装配至少一个第一配重模块;支承装置,该支承装置与支架底座主体连接,并且在至少三个点处与地板接触用以定位支架底座;以及与支架底座主体以可拆卸的方式连接的附加主体,该附加主体设置用于装配其他附加配重模块,其中支架底座主体底侧面对由所述至少三个点限定的平面,其中所述支架底座主体底侧与所述平面之间的最短距离大于10厘米。支架底座主体中用于装配至少一个第一配重模块的凹部面向所述平面开口。因此,在装配配重模块和/或附加主体时,需要将支架底座翻过来并从而将螺钉旋拧到底座底侧相应的孔内以将配重模块牢固地组装到支架底座主体上。最后,将支架底座翻回 ...
