Optical navigation marker structure and instrument navigation target

Abstract

The utility model relates to the technical field of surgical navigation, and provides an optical navigation marker structure and an instrument navigation target, and the optical navigation marker structure comprises a substrate, an optical layer, a light-transmitting layer and a barrier layer. The optical layer is arranged on the substrate, the light-transmitting layer is arranged on the side, away from the substrate, of the optical layer, the blocking layer is arranged on the side, away from the optical layer, of the light-transmitting layer, and an optical emitting area is formed in the blocking layer. According to the optical navigation marker structure provided by the invention, the light-transmitting layer and the barrier layer are arranged on the optical layer, and the barrier layer and the light-transmitting layer can reduce the risk that the optical layer is exposed and play a corresponding role in protecting the optical layer, so that the probability that the optical layer falls off or fails is reduced.
