摘要：
The utility model relates to a minimally invasive positioning device for pedicle screws.It has two positioning rods.Fixed on one vertebra to provide two nonparallel rods；Certain position board,The utility model has a first positioning tube body.The first and second positioning tube bodies,A long transverse notch,And a plurality of sleeve combinations,The second positioning tube body has a longitudinal opening for communicating with the long transverse gap.In the process of one of the two non parallel rods passing through the first positioning tube body,The second rod body is made to enter the second positioning tube body through the long transverse gap and the longitudinal opening.So as to complete a positioning program；And a plurality of metal nails,For inserting the vertebra through the plurality of sleeve combinations after the positioning procedure is completed,A plurality of pedicle screws are guided to lock into the vertebra after removing one of the inner sleeves of each sleeve combination.一種椎弓根螺釘微創定位裝置，具有：二定位桿，用以固定在一脊椎骨上以提供二非平行桿體；一定位板，具有一第一定位管體、一第二定位管體、一長形橫向缺口、及複數個套筒組合，該第二定位管體具有一縱向開口以與該長形橫向缺口連通，俾以在所述二非平行桿體之一桿體穿過該第一定位管體的過程中，使另一桿體藉由該長形橫向缺口及該縱向開口進入所述第二定位管體內，從而完成一定位程序；以及複數根金屬釘，用以在該定位程序完成後經由所述複數個套筒組合插入該脊椎骨，並在去除各所述套筒組合之一內套筒後引導複數根椎弓根螺釘鎖入該脊椎骨中。
