Method for simulating soft tissue surgery path planning through implicit surface algorithm

The invention relates to a method for simulating soft tissue surgery path planning through an implicit surface algorithm. The method comprises the steps of S1, acquiring medical image data of a specific case soft tissue part; S2, establishing a three-dimensional geometric model; S3, acquiring instrument characteristic data of a resection surgery; S4, based on man-machine interaction interface designing, performing tracking and positioning on operation of a surgery instrument entity or model of a soft tissue resection surgery, calculating a relative position of the surgery instrument entity ormodel to a dissecting model, and detecting a resection instrument operation amount at each time; S5, based on the implicit surface algorithm, applying an operation amount on the soft tissue model, andcalculating an action amount which corresponds with the current operation amount according to an instrument characteristic, wherein the action amount comprises an effective ablation area and an ablation contour of an ultrason
