Embodiment Construction

[0028] figure 1 An overall processing flow chart of the guide wire simulation method for cardiovascular interventional surgery simulation is given, and the present invention will be further described below in conjunction with other drawings and specific embodiments.

[0029] The invention provides a method for simulating a solid combustion process based on a thermodynamic model. The main steps are as follows:

[0030] 1. Initialize the method of constructing the guide wire model

[0031] The spatial shape of the guidewire can be approximated by its centerline, ignoring the volume of the guidewire. For a guide wire represented continuously, the centerline can be represented by the curve r(σ)=(r x (σ), r y (σ), r z (σ)) T representation, enabling a continuous spatial shape description of the guidewire. Curve expression r(σ):[0,1]→R 3 Assign a spatial position r(σ) for each line element value σ∈[0,1] on the centerline of the elastic thin rod. Only relying on the descripti...

Abstract

The invention provides a guide wire simulation method facing cardiovascular interventional surgery emulation. The method comprises four steps that: an initialization stage is used for initializing each kind of basic physical information of a guide wire and the initial state of the guide wire and constructing a guide wire physical model; in a guide wire model physical emulation stage, a guide wire motion equation is solved according to external force and energy equations to obtain the displacement and state updating of the guide wire; in the guide wire and ambient environment interaction stage, the guide wire generates interaction with the ambient environment in the inserting process in a blood vessel, so the physical state of the guide wire is influenced; in a guide wire simulation optimization stage, the guide wire emulation is subjected to optimization treatment according to the state characteristics of the current guide wire. The guide wire simulation method has the advantages that the hidden method physical simulation emulation is carried out on the guide wire, in addition, the interaction with the ambient environment is also realized, the method is applied to the cardiovascular interventional surgery, and the characteristics that the stability is high, the real-time performance is good, the physical reality sense is high, and the high fidelity is realized are realized.

Description

technical field [0001] The invention relates to a guide wire simulation method for cardiovascular interventional operation simulation, and the invention only involves computer simulation, but does not involve real operation behavior and human body interaction. Background technique [0002] The development of my country's medical and health services is facing three major problems: the shortage of high-level medical personnel, the unbalanced distribution of high-quality medical resources, and the high incidence of vicious doctor-patient disputes. Among them, the large-scale training and training of suitable medical talents has become a major problem facing the healthy development of my country's medical and health services. In addition, modern medical surgery presents a development trend of precision, minimal invasiveness, and individualization. The current surgical operation mostly depends on the subjective experience and proficiency of the doctor, with low precision and poo...
