Method and system for simulating minimally invasive puncture surgery

Abstract

The invention provides a method and system for simulating minimally invasive puncture surgery. Data information of a surgical site can be accurately acquired by scanning image data, the accuracy of a surgery simulation operating environment is ensured, and a lesion body and human tissue are modeled independently. A surgery simulation scene and a real scene are combined by means of the augmented reality technique, so that sensory experience of users is improved, an operator can accurately observe the condition of surrounding important blood vessels of human tissue when looking for a puncture point during surgery simulation, the operator can be trained to find out the puncture point accurately, and therefore the success rate of surgery can be increased. Meanwhile, during collision detection, interaction between a virtual surgical instrument and virtual human tissue is divided into two phases, force feedback equations of a soft tissue deformation phase and a puncturing phase are established respectively, reception and output are conducted by means of force feedback equipment, as a result, the operator can sense current operation force accurately during simulated experiment operation, and experiment immersion sense is improved.

Description

technical field [0001] The present invention relates to the technical field of surgery simulation, and more particularly, to a method for simulating minimally invasive puncture surgery and a system for simulating minimally invasive puncture surgery. Background technique [0002] At present, compared with traditional surgery, minimally invasive surgery only causes very small trauma to human tissue, and this technology can significantly reduce postoperative recovery time and mortality. Therefore, research on minimally invasive surgery and related auxiliary diagnosis and treatment methods has become a hot spot in medical technology research today. In order to improve the success rate of minimally invasive surgery, it is usually necessary to simulate the surgery in advance, and surgical simulation is born as needed. [0003] The core function of surgical simulation is embodied by feedback interaction. The system receives the user's operation through the input device, calculates...
