In-vitro vascular embolism simulation system and method

Abstract

The invention relates to the technical field of medical equipment, in particular to an in-vitro vascular embolism simulation system and method. Initial pressure signals are provided by pressure sensing equipment, and fluid mechanics states of a tumor vascular network and an embolism agent in a vascular embolism process are simulated through a digital simulation technology. According to the scheme, different tumor vascular networks can be restored, injection of different embolism agents and simulation of the embolism effect can be achieved, enough immediacy and immersion are given to an operator, and the training effect is improved. By injecting different embolism agents, the visitors can feel the viscosity and injection pressure of different embolism agents from the touch sense, so that the visitors can have the feeling of being personally on the scene, and the difference of different embolism agents in the aspects of injection pressure and embolism effect can be evaluated.

Description

Technical field [0001] The present invention relates to the field of medical equipment, and more particularly to a vascular embolization simulation system and method. Background technique [0002] Liver cancer is the world's sixth common cancer, and is the fourth largest cancer. In 2018, about 840,000 new liver cancer patients worldwide, with an average of 780,000 patients died of liver cancer, and China is a large number of liver cancer, and the average annual new liver cancer cases and deaths account for all. Half of the world. Although surgical resection is the most ideal liver cancer treatment plan, due to the high concealment of early liver cancer, the symptoms are not obvious, it is difficult to diagnose, so a large number of patients have been diagnosed until the mid-term, which makes only 25% of early cases can pass Surgical resection, liver transplantation and other means are treated, and liver cancer has strong tolerance for chemotherapy and radiotherapy, and the treatm...
