微創手術的立體定位裝置

A three-dimensional positioning device for mini-incision surgery comprises a base body, two angle-positioning components, a positioning frame, a sliding seat positioning component, an alignment component, an alignment-adjusting component, and a fine adjusting component. The base body comprises two first frame bodies and two second frame bodies. Each angle-positioning component is installed separately on a pivotal connection portion of each first frame body. Two ends of the positioning frame are respectively fixed to the angle-positioning components. The sliding seat positioning component is slidable along a slide rail portion of the positioning frame according to the predetermined lesion position. The alignment component is adjustably mounted to the second frame body. The alignment-adjusting component is installed on the alignment component. The fine adjusting component is installed on the alignment-adjusting component. Thus, the mini-incision surgery is provided with the effect of more accurate positioning, simple and convenient operation, and light and handy structure.
