Abstract:
We present a hepatic surgery operation simulation system based on support force feedback. The simulation process of livervirtual surgery with force feedback mainly includes three-dimensional reconstruction of CT image,spatial scene construction,real-timedynamic interaction design and operation simulation with force feedback. After the completion of the virtual simulation environment,users can learn the immersive knowledge and practical operation training of liver surgery cutting in the virtual surgery scene through thehelmet mounted display device HTC vive pro and its force feedback handle. According to the lesion characteristics of clinical cases,through the acquisition and processing of liver medical CT tomography images,the 3D reconstruction of human liver model based on VRvirtual reality roaming system is obtained. Through the design of real surgical scene and simulation of surgical operation, a set ofsimulation system including liver pathology is designed. The virtual simulation application system of human liver surgery is constructedby introducing helmet virtual roaming device and force feedback vibration handle, which provides an effective application scenariosolution for medical surgery training simulation. The experiment shows that the proposed method can be effectively applied to therendering of virtual roaming scene based on 3D reconstruction of CT image,especially in the field of medical surgery training simulation,and has strong application innovation value.
