Transparent Blood Vessel Model for X-Ray-Free Procedure Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical training models for vascular diseases, particularly aneurysms, either expose trainees to harmful X-rays or lack realism and practicality, failing to simulate realistic procedural scenarios with real instruments and physiological conditions.
Innovation Solution
A medical training model that uses an X-ray-free optical system with a photo-optical setup, allowing for realistic simulation of vascular procedures by replicating human anatomy and incorporating real instruments, and simulating physiological properties like temperature and blood flow, using modular and customizable blood vessel models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real human organs or cadavers are used for training, then training realism and educational value are improved, but ethical concerns, cost, and availability deteriorate
Solution Approach 1:
The patent creates photorealistic 3D digital copies of human organs and tissues that can be manipulated and dissected virtually. These digital replicas maintain anatomical accuracy while eliminating the need for actual human specimens, thus preserving training realism while removing ethical and logistical complexities.
Solution Approach 2:
The patent replaces physical dissection of real organs with virtual reality-based digital manipulation. Users interact with photorealistic 3D models through VR interfaces, substituting mechanical dissection tools and physical specimens with digital counterparts that provide the same educational value without ethical concerns.
2Ease of manufacture
If traditional 2D images or simplified models are used, then cost and simplicity are improved, but training effectiveness and anatomical accuracy deteriorate
Solution Approach 1:
The patent transitions from 2D images and flat diagrams to immersive 3D photorealistic virtual models. This dimensional enhancement allows users to explore anatomical structures from multiple angles, understand spatial relationships, and perform virtual dissections with the same simplicity of access as traditional materials but with dramatically improved training effectiveness.
3Adaptability or versatility
If extensive anatomical structures are included in the model, then training comprehensiveness is improved, but model complexity and processing requirements deteriorate
Solution Approach 1:
The patent divides complex anatomical structures into modular, hierarchically organized segments that can be independently loaded, manipulated, and studied. Users can access complete anatomical systems for comprehensive training or focus on specific organ systems as needed, allowing the model to scale in complexity based on training requirements while maintaining manageable processing demands through selective loading.

AI summary
Described is a medical training model having at least one blood vessel model (1) which can be connected to an anatomically replicated substitute circulatory system (2) in at least one practice region and in which a real instrument (17) is used, further having an image recording device (3) for creating measured images of the at least one blood vessel model (1), and having an image processing device (11) which converts the recorded measured images into an imaging blood vessel representation and makes same displayable on a screen (12), wherein the image recording device (3) is designed as a photo-optical system (8) which records transmitted-light images (13) as measured images of the at least one blood vessel model (1) for the simulation of medical activity, for which purpose the at least one blood vessel model (1) is replicated in a transparently produced solid-body block (4) for a contrast between the transparent solid-body block (4) and the non-transparent instrument (17).
