Development and assessment of a haptic-enabled holographic surgical simulator for renal biopsy training

Abstract

In this paper, a high-immersive surgical training system for renal biopsy using holographic demonstration and haptic feedback is presented to push the limitation of virtual medical training development. Proposed system is including: holographic visual rendering pipeline reconstructed by the patient-specific CT images; haptic rendering pipeline implemented by the dual-hands 6-DOF haptic devices connected with surgical instruments of image guide and immersive 3D display learning operating room environment. Twenty-four medical students and eight experienced thoracic surgeons from the Yunnan First People’s Hospital are invited to evaluate our holographic-based training system through the subjective and objective assessment test, respectively. Experiment result from the face, content, improvement, and construct evaluations demonstrated a high performance than the existing VR-based trainer, especially the puncture accuracy of medical students’ group, was improved by 30.8% after training.
