Problems solved by technology

However, once a non-ruptured aneurysm ruptures, it will cause spontaneous subarachnoid hemorrhage, and then evolve into a ruptured aneurysm. The fatality and disability rate of a ruptured aneurysm exceeds 50%, which seriously threatens the lives of patients

Abstract

The invention discloses a micro-catheter virtual intervention path simulation method and device thereof, and the method comprises the steps: n central line points are selected from a central line after the central line of a virtual blood vessel is generated; m points are selected from the edge of a virtual cross section where each center line point is located, h points are randomly generated inside the virtual cross section, and a point set corresponding to the virtual cross section where each center line point is located is obtained; according to the cut-off point of the virtual blood vessel,each point set and a starting point of the virtual blood vessel, a target broken line corresponding to the center line is determined, and the elastic potential energy sum of the target broken lines is smaller than the elastic potential energy sum of any broken line except the target broken line in the broken line set; and smoothing and interpolation operation can be performed on the target brokenline to obtain a continuous curve segment, and the continuous curve segment is determined as a virtual intervention path of the virtual micro-catheter corresponding to the virtual blood vessel. Therefore, the simulation accuracy of the interventional path of the micro-catheter can be improved, and then the plasticity of the micro-catheter and the accuracy of the micro-catheter entering the affected part can be improved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, and in particular to a path simulation method and device for virtual intervention of a micro catheter. Background technique [0002] Intracranial aneurysm, also known as cerebral hemangioma, is a kind of tumor-like protrusion formed by the abnormal expansion of the lumen of the intracranial artery. It is a common vascular disease. According to statistics, every 100 adults in my country Seven of the adults are carriers of aneurysm. Intracranial aneurysms can be divided into non-ruptured aneurysms and ruptured aneurysms. The vast majority of intracranial aneurysms are non-ruptured aneurysms, and the annual rupture rate of non-ruptured aneurysms is only 0.05%. However, once a non-ruptured aneurysm is ruptured, it will cause spontaneous subarachnoid hemorrhage, and then evolve into a ruptured aneurysm. The lethality and disability rate of a ruptured aneurysm exceeds 50%, which seriously threaten...
