Cardiac radiofrequency ablation surgery intelligent assistant system based on AR and AI technologies

Abstract

The invention relates to a cardiac radiofrequency ablation surgery intelligent assistant system based on AR and AI technologies. Specifically, a three-dimensional model of a heart and catheter detection scan data are transmitted; a 3D modeling module constructs a three-dimensional model of a heart cavity in a modeling space based on the catheter detection scan data, based on the relative positional relationship between the heart cavity and the heart, the three-dimensional model of the heart and the three-dimensional model of the heart cavity are matched, and the determined position of the three-dimensional model of the heart in the modeling space is determined and retained; the position of a coronary sinus electrode in the real heart is transmitted; the3D modeling module carries out calibration in the modeling space based on the position of the coronary sinus electrode in the real heart, updates a position point of the coronary sinus electrode in the modeling space based on the changedposition of the coronary sinus electrode in the real heart, and simultaneously updates the position of the three-dimensional model of the heart in the modeling space; the 3D modeling module carries out calibration in the modeling space based on the position of the ablation catheter in the real heart; and an AR head-mounted display device shows a position point where the ablation catheter is located in the three-dimensional model of the heart.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to an intelligent assistant system for heart radiofrequency ablation surgery based on AR and AI technologies. Background technique [0002] Cardiac radiofrequency ablation is a mature technique for the diagnosis and treatment of cardiovascular diseases. After puncturing the blood vessels on the surface of the body, under the continuous projection of digital subtraction, it is sent into the heart catheter, and the arrhythmia is diagnosed through a specific cardiac catheter operation technique. It is the most advanced means of heart diagnosis and treatment at present. Compared with traditional thoracotomy, its surgical trauma is small, only local anesthesia is required, the operation time is short, the patient suffers less pain, and the operation safety is high. The advantages of fast postoperative recovery, relatively low cost, and immediate curative effect. However, he...

Problems solved by technology

However, he also has a lot of information that doctors need to pay attention to during the operation, and it is difficult to visually display the position of the ablation catheter during the operation. The above reasons lead to the fact that radiofrequency doctors can only get started after long-term (more than 1 year) training, compared with the intuitive coronary surgery in the Department of Cardiology , the current radiofrequency ablation surgery is difficult to operate and the number of doctors is seriously lacking. This is also the problem we decided to solve
