Simulation Training System for Intestinal Polypectomy Surgery Teaching
Background Pain Points
Intestinal polypectomy is a common endoscopic surgery, but the soft tissue undergoes significant deformation and the model topology changes during the cutting process are complex. Traditional training methods are difficult to provide realistic tactile and visual feedback, making it difficult for students to master the cutting force and tissue response.
Solution
Collaborate with a medical solution company in Chengdu to jointly develop a virtual simulation teaching system based on SOFA software simulation engine. The system supports real-time deformation of software tissues and dynamic changes in topological structures, accurately reproducing key surgical processes such as tissue cutting, segmentation, clamping, and bleeding. Combined with force feedback equipment, it provides precise tactile interaction.
Technical Highlights
Soft tissue deformability: realistic simulation of force response of flexible tissues such as intestinal wall
Model topology changes: support dynamic updates of organizational structure after cutting, segmentation, and other operations
High fidelity scene restoration: including key surgical events such as bleeding, clipping, and resection
Applied Value
Provide a safe and reproducible training environment for polypectomy surgery
Breaking through the difficulties of software organization simulation technology and enhancing the realism of training
Promote standardization and digital upgrading of endoscopic surgery teaching
