Problems solved by technology

Due to the small size of the subthalamic nucleus and inconspicuous borders, low resolution of intraoperative MRI images, and large electrode artifacts, electrode insertion directly based on image data will not only be difficult in operation, but also greatly affect the accuracy rate.

Embodiment 1

[0040] Such as figure 1 As shown, a model device for simulating the implantation operation of deep brain stimulation electrodes includes: a cranial brain model 1, a pressure sensor 2, a data processing module 3 and an output device 4. The cranial brain model includes a subthalamic nucleus 5, a pressure sensor 2 is set on the subthalamic nucleus 5, the pressure sensor 2 is connected with the data processing module 3, and the data processing module 3 is electrically or signally connected with the output device 4 located outside the brain model 1.

Embodiment 2

[0042] The cranial brain model can also include the cranial cavity structure, intracranial blood vessels, ventricles and brain tissue formed by the cooperation of the upper skull and the lower skull, the subthalamic nucleus, intracranial blood vessels, and ventricles are located in the cranial cavity structure, and the The brain tissue is filled in the cranial cavity, and the material of the brain tissue can be soft materials such as silica gel, gel or rubber. A complete brain model structure can make the simulation more similar to the actual human brain environment, thereby further improving the accuracy of preoperative simulation. The upper skull, lower skull, cranial blood vessels, subthalamic nucleus, and ventricles in the brain model are formed by 3D printing according to the three-dimensional image data of the patient's brain structure. The brain model prepared in this way is completely personalized. It provides a good clinical reference value for doctors to study specif...

Description

technical field [0001] The present invention relates to the technical field of deep brain stimulation electrode implantation simulation operations, and more specifically, to a model device for simulating deep brain stimulation electrode implantation operations and a preparation method thereof. Background technique [0002] The subthalamic nucleus (STN) is an important structure in the human brain related to Parkinson's and other involuntary movements, which belongs to functional neurosurgery. The current related operations mainly rely on a positioning iron frame with coordinate information, which is fixed on the patient's head, and the coordinates are adjusted. The patient takes this iron frame to do CT or MRI (magnetic resonance imaging), and then combines the image data and After the recorded coordinate information, microelectrodes are implanted in the patient's brain to the subthalamic nucleus for deep electrophysiological stimulation of the subthalamic nucleus (STN-DBS)....
