Referring to fig. 4, the modeling module 4 includes: the vertebral focus position acquisition module is used for acquiring the vertebral focus position; the adjacent lumbar vertebra parameter acquisition module is used for acquiring parameters of two adjacent lumbar vertebrae of the spinal focus; and the vertebral focus three-dimensional establishing module is used for establishing a vertebral focus three-dimensional model. When the focus is generated on the spine, the possibility of injury of two sections of lumbar adjacent to the focus of the spine exists, so that the success rate of the operation can be increased through the position acquisition module of the focus of the spine and the parameter acquisition module of the adjacent lumbar, the possibility of relapse after the operation can be reduced, and the time for postoperative rehabilitation is shortened.

Referring to fig. 4, the control module 8 includes: the display module is used for importing the complete spine three-dimensional model to the display module of the intelligent device to display the complete spine three-dimensional model; and the processing module is used for carrying out the operations of selecting, deleting, adding, scaling in equal proportion, moving, rotating, color exchanging, marking and transparency increasing and decreasing functions on the complete vertebra three-dimensional model.

Please refer to fig. 4, which summarizes the following: medical personnel acquire the spine image data of a patient by utilizing CT through an image acquisition module 2, analyze parameters of a spine focus through an analysis module 3, then start working through a modeling module 4, establish a three-dimensional model of the spine focus, determine a connection point of the three-dimensional model of the spine focus, then start calling the three-dimensional model of the spine in a three-dimensional data storage library through a splicing module 7, splice the three-dimensional model of the spine in the three-dimensional data storage library with the three-dimensional model of the spine focus through the connection point of the three-dimensional model of the spine focus, and generate a complete three-dimensional model of the spine; and leading the complete spine three-dimensional model into intelligent equipment, and realizing control on the complete spine three-dimensional model in the intelligent equipment. When the spine is modeled in three dimensions, the whole lumbar vertebrae of a patient does not need to be modeled again, so that the modeling efficiency is improved, the working time of doctors is shortened, the waiting time of the patient is shortened, and the success rate of the operation is improved. Meanwhile, when the three-dimensional model of the patient is needed in the accidental situation during the operation, the image data of the focus of the patient can be locally scanned, only the focus of the patient is modeled, then the spine three-dimensional model in the three-dimensional data storage library is called for splicing, the rapidness and the accuracy are guaranteed to a certain extent, the intelligent equipment controls the complete spine three-dimensional model, the variability of the accidental situation during the operation is increased, and medical staff observe the complete spine three-dimensional model in multiple angles, so that the judgment on the focus parameters of the patient during the operation is increased, and the success rate of the operation is increased.

Although the methods and systems described in detail herein are generally described with respect to the spine, it is contemplated that the modeling methods and systems described above may be applied to the liver, spleen, or any other organ.

While several embodiments of the present disclosure have been illustrated in the accompanying drawings, it is not intended to limit the disclosure thereto, but rather to make the disclosure as broad in scope as the art will allow, and the specification should be read likewise. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments.
