Problems solved by technology

[0010] The technical problem to be solved by the present invention is to overcome the fact that the existing neurosurgery navigation technology cannot effectively assist doctors to quickly, accurately and safely establish cranial puncture paths for neurosurgery navigation, which leads to overreliance on Due to the doctor's clinical experience, the doctor's work is difficult and stressful, and the surgical risk is relatively high. A new method and system for establishing a cranial puncture path for neurosurgery navigation is proposed.

Embodiment approach

[0060] According to some preferred embodiments of the present invention, the feature points include part or all of the following: lateral canthus, center of external auditory canal, nasal heel, each skull, each skull joint, each bony landmark, cavity, and fossa. The feature points referred to here may refer to the geometric center points related to these feature points. And preferably, in this step S3, the cross-section, sagittal plane and coronal plane of the brain in the medical image data are replaced by the three-dimensional coordinate system of the brain model constructed.

[0061] In steps S2 and S3, for example, the lateral canthus point can be identified based on the image information involved in the cranial brain model. in such as image 3 , 4 In the example shown, the connection line of the external auditory canal can be established according to the image information, and the virtual "OM" connection line and the bilateral external auditory canal (the center of the ...

Abstract

The invention discloses a craniocerebral puncture path establishment method and system for neurosurgery navigation. The craniocerebral puncture path establishment method comprises the steps of generating a three-dimensional craniocerebral model based on craniocerebral medical image data; identifying a plurality of feature points in the craniocerebral model, and requesting to confirm or manually modify geometric features of the feature points in the craniocerebral model; constructing a three-dimensional coordinate system of the craniocerebral model according to the geometric features of the confirmed or manually modified feature points; generating a dangerous area and a puncturable area in the craniocerebral model; and establishing a puncture path based on the dangerous area and the puncturable area. According to the craniocerebral puncture path establishment method and system for neurosurgery navigation, a doctor can be effectively assisted in quickly, accurately and safely establishing the craniocerebral puncture path for neurosurgery navigation, and the safety of a craniocerebral puncture drainage operation is particularly improved.

Description

technical field [0001] The invention relates to neurosurgery navigation technology and processing of cranial brain image data, in particular to a cranial puncture route establishment method and system for neurosurgery navigation. Background technique [0002] Hypertensive cerebral hemorrhage is a common disease in neurosurgery. The commonly used surgical methods include craniotomy for hematoma removal and stereotactic soft channel minimally invasive puncture hematoma drainage (cube positioning soft channel puncture technique), among which stereotactic soft channel minimally invasive puncture With the development of neuronavigation technology and the application of surgical instruments, drainage is also being updated and upgraded in surgical methods, gradually developing in the direction of higher precision, lower risk, and easier. [0003] In the past ten years, there has been a lot of research work on puncture points and targeting in surgery. Moreover, puncture and drainage...
