A stent release simulation system based on virtual imaging of real blood vessel model

Abstract

The invention discloses a vascular stent release simulation system based on virtual imaging of a real blood vessel model, comprising: constructing a three-dimensional image model of a blood vessel; determining the position of a plaque according to the three-dimensional image model of a blood vessel; planning the progress of a blood vessel stent according to the position of the plaque Path: send the vascular stent to the target position according to the traveling path, and release the vascular stent. The present invention simulates the release of the vascular stent in the three-dimensional image model of the blood vessel, obtains the best vascular stent travel path, can guide the doctor to release the vascular stent in the actual operation, and reduces the dose of the contrast agent injected and the radiation received by the patient , improving the quality of medical services.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vascular stent release simulation system based on virtual imaging of a real blood vessel model. Background technique [0002] Too much cholesterol in human blood can easily deposit on the inner wall of arteries to form plaques, which can cause atherosclerosis, eventually leading to excessive narrowing of the vessel lumen, insufficient or interrupted blood supply. At present, the treatment method of atherosclerosis widely adopts vascular stent implantation. [0003] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon expansion to support the stenotic and occluded segment of the vessel, reduce elastic recoil and reshaping of the vessel, and maintain smooth blood flow in the lumen. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, renal artery stents, ...

AI Technical Summary

Problems solved by technology

In the existing vascular implantation, multiple vascular imaging examinations are performed during the implantation of the vascular stent to ensure that the stent will not touch the plaque during the advancement. This method will cause the patient to inject too much contrast agent and receive Excessive radiation, and because of the two-dimensional images obtained, it is not possible to accurately determine whether the stent will touch the plaque during the advancement of the vessel
