Modular Surgical Simulation Device for Anorectal Malformation Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical training for rare conditions like anorectal malformations and cleft lip is challenging due to the infrequency of these procedures, making it difficult for surgeons to obtain adequate training without risking patient health and safety during live training.
Innovation Solution
A modular surgical simulation device with high-fidelity simulated anatomical models that can be reused with different conditions, featuring reinforced tissues and orientations to mimic actual surgical environments, allowing surgeons to practice procedures safely and repeatedly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical training is performed on live patients, then surgical skills can be developed, but patient health and safety are at risk
Solution Approach 1:
The patent creates high-fidelity anatomical models that replicate the appearance, texture, and structural properties of real human tissues. These models include simulated skin layers, fat layers, muscle layers, and organ structures that closely mimic actual anatomy, allowing surgeons to practice procedures on realistic copies rather than real patients.
Solution Approach 2:
The patent modifies physical parameters of the anatomical models by incorporating reinforcing materials at specific locations and orientations to simulate the mechanical properties of underlying structures. This allows the models to provide appropriate resistance and feedback during surgical procedures while remaining safe for training purposes.
2Productivity
If surgical procedures are practiced repeatedly, then surgical skills improve, but the same anatomical models would need to be reused extensively
Solution Approach 1:
The patent uses composite materials consisting of flexible matrix materials (such as silicone or rubber) combined with reinforcing materials (such as fabrics, meshes, or structural elements). This composite construction provides both the realistic tactile properties needed for training and the enhanced durability required for repeated use.
Solution Approach 2:
The patent applies reinforcing materials selectively at specific locations and orientations within the anatomical models based on where surgical procedures are most likely to occur. This localized reinforcement provides enhanced durability at critical areas while maintaining the overall flexibility and realism of the model.
3Ease of operation
If anatomical models include realistic tissue properties, then training realism improves, but the models become more complex to manufacture
Solution Approach 1:
The patent divides the anatomical model into distinct layers and components (skin layer, fat layer, muscle layer, organ structures) that can be manufactured separately and then assembled. Each layer can be produced using optimized manufacturing processes, and the modular design simplifies the overall manufacturing complexity while maintaining realistic tissue properties.

AI summary
Surgical simulation devices including surgical models of various anatomical malformations as well as their methods of use and manufacture are described. In some embodiments, a surgical simulation device includes a base, a surgical model that simulates an anorectal malformation, and a model support. The model support is an internal volume sized and shaped to receive at least a portion of the surgical model such that an operating surface of the surgical model is exposed. The model support is releasably engaged with the base. In other embodiments, surgical models with simulated tissues including tissue reinforcement are described.
