Simulation method for intracranial aneurysm treatment and control device

Abstract

The invention provides a simulation method and device for intracranial aneurysm treatment. The method comprises the following steps: establishing a three-dimensional structure of a spring ring and placing the spring ring into an arterial aneurysm: packaging the spring ring into a simulated catheter in a simulated calculation manner and then releasing the spring ring into the arterial aneurysm; establishing a three-dimensional structure of a stent and placing the stent into an arterial aneurysm carrying blood vessel: compressing and placing the stent into a micro catheter in a simulated calculation manner, then bending the stent and the micro catheter, and releasing the stent into the arterial aneurysm carrying blood vessel; establishing a structure of the spring ring, and when the spring ring is placed in the arterial aneurysm, simulating the spring ring into a three-dimensional Euler-Bernoulli beam; establishing a three-dimensional structure of the stent, and when the stent is placed in the arterial aneurysm carrying blood vessel, simulating the stent into a three-dimensional shell unit; when the stent is released into the arterial aneurysm carrying blood vessel, bending the stent and the micro catheter along the central line of the arterial aneurysm carrying blood vessel. The device is used for implementing the simulation method. According to the simulation method and the device, the simulation calculation efficiency can be improved, and the calculation time is shortened.

Description

technical field [0001] The invention relates to the field of translational medicine, in particular to a method for simulating the treatment of intracranial cerebral aneurysms and a device for realizing the method. Background technique [0002] Intracranial aneurysm is a common brain disease, which is very harmful to the human body. Because intracranial aneurysm is a pathological bulge of the intracranial artery wall, such as figure 1 As shown, the aneurysm 11 is usually formed on the arterial wall of the parent vessel 10, and is often found at the arterial bifurcation of the circle of Willis in the cerebral vessel, and the consequences of aneurysm rupture are fatal, and about half of the patients cannot Survival, the remaining half of the patients are often unsatisfactory after treatment, usually with varying degrees of physical dysfunction. [0003] Coil embolization is currently the most common and effective method for treating aneurysms, such as figure 2 As shown, the ...

AI Technical Summary

Problems solved by technology

Just because the method captures all the details of its mechanical properties and behavior, the method takes a very long time in computation and thus cannot be widely used in practice

For example, the HiFiVS calculation based on the finite element method takes more than 100 hours to calculate the delivery process of the dense mesh stent, which is time-consuming, which often leads to a large amount of cost and time for this method, making it difficult to be popularized and applied clinically.
