Surgical Repair Model Simulation for Tissue Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue modeling technologies fail to provide realistic simulations of how implantable surgical repair devices, such as meshes and sutures, interact with tissue during patient activities, limiting their effectiveness in pre-operative planning and increasing tissue defect recurrence rates.
Innovation Solution
A computer-based method and system that generates an observable model of an implantable repair material secured to a patient, allowing clinicians to simulate the effects of patient activities on the repair material, including force, bulging, and stress fields, using a software application on a computing device, which processes patient data to depict the interaction of repair materials with tissue in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If tissue imaging techniques are used for pre-operative planning, then anatomical visualization is improved, but tissue interaction simulation capability deteriorates
Solution Approach 1:
The patent creates a digital copy or model of the patient's tissue anatomy based on imaging data, allowing virtual simulation of repair device interactions without requiring physical presence of the actual tissue. This digital twin approach preserves anatomical accuracy while enabling interactive simulation capabilities that imaging techniques alone cannot provide.
2Productivity
If repair devices are selected based on standard sizing, then device availability is improved, but patient-specific fit precision deteriorates
Solution Approach 1:
The patent enables dynamic adjustment of repair device parameters (size, shape, fixation method, material properties) within the simulation environment to optimize fit for each patient's unique anatomy. Clinicians can modify device parameters virtually to achieve precise customization without leaving the planning software, bridging the gap between standard device availability and patient-specific precision.
3Strength
If more fixation points are used to secure repair material, then fixation strength is improved, but tissue damage and surgical complexity deteriorate
Solution Approach 1:
The patent performs preliminary simulation of fixation strategies before actual surgery, allowing clinicians to test different fixation point configurations, densities, and methods in the virtual model. This pre-surgical optimization identifies the minimum necessary fixation points required for adequate strength, avoiding both over-fixation (excessive tissue damage) and under-fixation (insufficient strength).

AI summary
A method of generating a computer-based observable model of an implantable repair material secured to a patient is provided. The method includes processing data corresponding to a patient using a computing device including a processor and a memory storing a software application executable by the processor. The method also includes indicating an implantable repair material and a fixation for securing the implantable repair material to the patient and indicating a distribution of the fixation about the implantable repair material. The method also includes generating an observable model of the implantable repair material secured to the patient on a display operably associated with the computing device. The observable model depicts the indicated distribution of the fixation about the implantable repair material.
