Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack the ability to effectively assess the physical changes in an abdomen after a laparoscopic surgical procedure, particularly the performance of surgical implants, in a patient-specific environment, which can lead to uncertainties in surgical outcomes.
Innovation Solution
A physical abdominal surgical simulation system that includes a patient-specific abdominal model with biomechanical properties, an image acquisition and analysis system, and a method to compare the changes between inflated and deflated states of the abdominal model during a simulated laparoscopic procedure, allowing clinicians to evaluate surgical implants and techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the abdominal wall is inflated during laparoscopic surgical procedure, then the workspace is created and abdominal viscera are separated from the abdominal wall, but physical changes occur after deflation that can affect surgical outcomes
Solution Approach 1:
The system captures images and data of the surgical site during the inflated state (while the workspace exists) and then again after deflation, allowing clinicians to assess and plan for physical changes before they occur in the actual patient. This preliminary assessment enables proactive adjustment of surgical plans to account for post-deflation changes.
Solution Approach 2:
The system provides visual feedback by comparing images taken during inflation versus deflation, showing clinicians the actual physical changes that occur. This feedback loop allows for evaluation of how surgical implants and repairs perform under different abdominal pressure conditions, improving reliability of surgical outcomes.
2Shape
If surgical implants are secured to the abdominal wall during inflated state, then the mesh or patch conforms to the abdominal wall, but the physical configuration changes after deflation
Solution Approach 1:
The system captures the configuration of surgical implants during the inflated state when the mesh is secured to the abdominal wall, and then captures post-deflation configuration. This allows clinicians to predict and plan for configuration changes before they occur, enabling better implant selection and placement strategies.
Solution Approach 2:
By providing visual comparison of implant configuration before and after deflation, the system gives clinicians feedback on how the mesh and repairs respond to abdominal pressure changes. This enables evaluation of implant performance and stability under different physiological conditions.
3Measurement precision
If a physical abdominal model is used to simulate surgical procedures, then patient-specific environment assessment is enabled, but the system complexity increases
Solution Approach 1:
The system uses a physical abdominal model that replicates patient-specific anatomy and tissue properties, creating a realistic copy of the patient's abdominal cavity. This allows clinicians to practice and assess surgical plans in a patient-specific environment without the risks associated with actual surgery, improving measurement precision while keeping the model manageable in complexity.
