Development of New Generation Portable Camera-Aided Surgical Simulator for Cognitive Training in Laparoscopic Cholecystectomy
Published on 2025-02-18 by Yucheng Li, Victoria Nelson, Cuong T. Nguyen, Irene Suh, Suvranu De, Ka-Chun Siu, Carl Nelson @MDPI
Abstract: Laparoscopic cholecystectomy (LC) is the standard procedure for gallbladder removal, but improper identification of anatomical structures can lead to biliary duct injury (BDI). The critical view of safety (CVS) is a standardized technique designed to mitigate this risk. However, existing surgical training systems primarily emphasize haptic feedback and physical skill development, making them expensive and less accessible. This paper presents the next-generation Portable Camera-Aided Surgical Sim[...]
Our summary: Development of cost-effective PortCAS for cognitive skill acquisition in LC, prioritizing cognitive training over force-based interactions, providing accurate tracking performance.

Procedure for Reconstruction, Modeling, and Fabrication Using Additive and Rapid Tooling Methods of a Training Model for Transsphenoidal Surgery
Published on 2025-02-18 by Giacomo Santona, Antonio Fiorentino, Francesco Doglietto, Mauro Serpelloni @MDPI
Abstract: The endoscopic transsphenoidal approach (ETA) is a novel approach used by neurosurgeons and otolaryngologists to treat pituitary adenoma, and it has a long learning curve. Training is mostly performed using cadaver heads, but their low availability and cost can limit their use. ETA training models can be used to overcome these limitations. In this panorama, additive manufacturing (AM) technologies represent a more flexible and cost-effective solution to fabricate custom-made training models. The[...]
Our summary: Procedure for developing a training model for endoscopic transsphenoidal surgery using AM technologies, including CT segmentation, STL file elaboration, and rapid parts tooling. The model is designed, 3D printed, or rapidly cast, and tested by an experienced neurosurgeon for feedback. Cost and time of prototype fabrication are also assessed.
