ABSTRACT　　The　invention　provides　a　teaching　tool　for　lateral　ventricle　puncture　surgery　based　on　AR　　augmented　reality　technology,　　which　comprises　a　brain　tissue　three-dimensional　model　library　　and　a　puncture　surgical　instrument　three-dimensional　model　library;　　The　identification　module;　　　Teaching　module　of　puncture　surgery;　　And　a　puncture　operation　module.　According　to　the　　invention,　　the　operation　in　the　real　world　under　the　camera　is　interacted　with　the　virtual　　puncture　operation　environment　in　the　computer.　Users　can　learn　the　lateral　ventricle　puncture　　operation　through　the　system　of　the　invention,　　which　greatly　reduces　the　teaching　cost　in　　hospitals　and　schools,　　and　doctors　and　students　can　use　the　system　to　carry　out　training　　repeatedly,　　so　long　as　the　identification　tools　and　computers　or　mobile　phones　are　available.　1/1　　FIGURES　　Image　of　　brain　　A　teaching　Identifiable　tools　such　as　　tool　for　CT　sean,　　　lateral　　Identification　　ventricle　module　Reverse　engineering　　punctuMr　　Punctule　operation-　Brain　tissue　　basedon　teaching　module　three　dimnsqional　　AR　model　　augmented　Petm(,　orainlibrary　　reality　module　　Figure　1　　Fig.1　A　system　module　diagram　of　the　present　invention.
