Abstract

The invention discloses a simulation method and device for the interventional embolization operation process. The method comprises the steps that according to the geometrical shape of an embolic substance bounding sphere, a winding path formula of embolic substances is established in a polar coordinate system; an angioma is selected, a network adjacency information based search algorithm is adopted, corresponding boundary conditions are set, all triangular patches belonging to the angioma are separated out, and the ball center and radius of an inscribed sphere of the angioma are calculated; a catheter is controlled to reach the angioma, and the embolic substances are pushed into the angioma through the catheter according to the winding path formula of the embolic substances and the ball center and radius of the inscribed sphere of the angioma. Accordingly, the simulation truth of interventional embolic substance winding can be improved while the operation simulation real-time performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of virtual surgery, in particular to a simulation method and device for interventional embolization surgery. Background technique [0002] Virtual surgery is the use of medical imaging data, using virtual reality technology to create a virtual environment in the computer, so that doctors can use the information in the virtual environment to carry out surgical planning, training, and actual surgery to guide the operation. The traditional surgical process has disadvantages such as high risk, great patient pain, and unsatisfactory postoperative results. The surgical effect is greatly affected by the doctor's personal professional level. The use of augmented reality technology allows medical workers to immerse themselves in virtual scenes, perceive and learn various surgical operations through sight, hearing, and touch, and experience and learn how to deal with the actual situation in clinical operations. This ...
