Operation navigation instrument with function of automatically recognizing lesion at craniocerebral part

The invention discloses an operation navigation instrument with the function of automatically recognizing a lesion at a craniocerebral part. The operation navigation instrument comprises a data reading module for reading image data of the craniocerebral part, wherein the data reading module is connected with an identifying module used for identifying the lesion in the image data of each layer, and the identifying module is connected with a modeling module used for establishing a craniocerebral part structure and lesion three-dimensional model by using a three-dimensional rebuilding manner. The operation navigation instrument disclosed by the invention can be used for intelligently recognizing brain tumors and other lesion parts to effectively increase the efficiency and safety of an operation.
