Problems solved by technology

However, the method has a large amount of calculation, and its speed cannot meet the real-time requirements of the simulation.
In addition, the guide wire is defined as a spring particle model, which defines a variety of complex forces, and limits the catheter / guide wire to the inside of the blood vessel. This method also sacrifices accuracy to a certain extent

Abstract

A surgical instrument moving simulation method at least comprises the following steps that CT images are obtained, and a vascular model is obtained by reestablishing; a surgical instrument model is obtained, and the surgical instrument model is subjected to self-adaptation discretization according to the vascular model; the surgical instrument model moves in the vascular model according to applied control signals; and collision detecting is carried out on nodes on the surgical instrument model and the vascular wall of the vascular model, and the balance position of the surgical instrument model after collision is obtained. The surgical instrument moving simulation method is good in facticity, high in speed, high in accuracy and good in robustness, and using requirements are met.

Description

technical field [0001] The invention relates to the medical field, in particular to a method for simulating the movement of surgical instruments based on interventional operations. Background technique [0002] Interventional surgery refers to making millimeter-scale tiny channels in the original pipeline of the human body or on the blood vessels and skin without exposing the lesion. CT), magnetic resonance (Magnetic Resonance, MR), B-mode ultrasonography (B-modeultrasonography) guided by the method of local treatment of the lesion. This method has become an important treatment method for diseases such as tumors and cardiovascular diseases due to its characteristics of small trauma, simplicity, safety and effectiveness, few complications and short hospital stay. Traditional interventional surgery training methods mainly include operation training in actual patient surgery, animal experiment operation training, and blood vessel model operation training. Surgical experience,...
