| Abstract Scope |
Current methods for pre-surgical planning rely heavily on simplified anatomical models, particularly lacking in their ability to simulate the complex behavior of vascular structures during surgical manipulation. Existing multi material inkjet approaches enable printed models to approximate the visual geometry of a human’s vascular system, but they do not exhibit realistic mechanical behavior. Leveraging methods from microfluidic device fabrication, we introduce a novel approach to print embedded vascular structures capable of realistically simulating mechanical interactions. These vessels can be cut, injected, and will actively bleed like their biological counterparts. This is achieved by co-printing photo-curable and non-photo-curable liquids. The non-curable liquid remains fluid within the printed channels, which are surrounded by a soft, tissue-like matrix formed by the cured photopolymer. We will demonstrate the realism and functionality of these printed vascular tissues through demonstrations that include cutting, needle insertion, and simulated bleeding. |
