Abstract

The present invention relates to a method for simulating and simulating soft tissue surgery path planning using an implicit surface algorithm: S1: Acquiring medical image data of soft tissue parts in a specific case; S2: Establishing a three-dimensional geometric model; S3: Obtaining instrument feature data for resection surgery; S4: Based on Human-computer interaction interface design, tracking and positioning the operation of the physical object or model of the surgical instrument for soft tissue resection surgery, calculating its relative position with the anatomical model, and detecting the operation volume of the resection instrument at each moment; S5: Based on the implicit surface algorithm, the The operating amount is applied to the soft tissue tissue model, and the corresponding action amount corresponding to the current operating amount is calculated according to the characteristics of the device. The action amount includes the effective ablation area and ablation contour of the tissue by the ultrasonic scalpel; S6: According to the calculated action amount, edit Modify the tissue model to show the dynamic changes including the path extension of the cut plane in the operation and the expansion of the boundary contour of the wound. The present invention can give users a more comprehensive and real pre-operative preview experience.
