Problems solved by technology

[0006] 1. The measurement and positioning method of intracranial anatomical landmarks does not take into account the curvature of the skull, and it is difficult to make the surgical path from the lesion to the localized scalp area the shortest
[0007] 2. Surgical approach planning does not consider important intracranial tissues

Embodiment Construction

[0060] The present invention will be further described below in conjunction with the accompanying drawings.

[0061] The invention directly acquires the three-dimensional model output by the imaging equipment of the hospital, mainly including brain tumors, the surface near the scalp and important tissues. Important tissues include blood vessels, nerves or other brain tissues. For the convenience of discussion, blood vessels are used as an example. All 3D models exist in the form of surface point sets, and the coordinates of data points in the point set are based on the original image data coordinate system. First, the coordinates of the tumor center point are calculated, which represent the position of the tumor in the coordinate system. Then traverse all points on the adjacent scalp, and locate the point with the shortest distance from the tumor center. Display the line connecting the shortest distance point and the tumor center point, and judge whether there is a blood ves...

Abstract

The invention belongs to the field of computer-assisted surgery, and in particular relates to a brain tumor surgery incision locating and approach planning method which is used for incision localization and surgical approach planning before a brain tumor resection surgery on the basis of a medical image. The method comprises the following steps: acquiring a tumor central point; locating a point, which keeps the shortest distance from the tumor central point, on the scalp; locating a point, which keeps the shortest distance from the tumor central point, within a region; acquiring tumor marginal points; determining a surgical incision location; and designing a surgical approach. Compared with other methods of locating brain tumor on scalp, the method disclosed by the invention, under the circumstance of effectively avoiding intracranial important tissues, guarantees the shortest route of the designed surgical approach and meets the requirement of precise localization of incision with the minimum additional wound.

Description

technical field [0001] The invention belongs to the field of computer-aided surgery, and in particular relates to a brain tumor surgical incision and approach planning method for performing incision positioning and surgical approach planning using medical images before surgery for brain tumor resection. Background technique [0002] Brain tumor is a neurological disease that seriously endangers human life and health. The most direct and effective way to treat brain tumors is neurosurgery, but surgery has high requirements for doctors. It not only requires doctors to accurately remove the lesion, but also to minimize the surgical incision to avoid additional trauma to the patient. However, traditional neurosurgery often relies on the doctor's surgical experience, and it is difficult to accurately locate and remove the lesion, which may easily cause deviation of the surgical approach and bring additional harm to the patient. Mastering the positioning technique of intracranial...
