Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a 3D simulation is created for surgical planning, then surgical precision and success probability are improved, but the realism and fidelity to actual surgical conditions deteriorate
Solution Approach 1:
The patent creates a virtual copy of the patient's actual surgical site using 3D modeling technology. The system generates a digital replica that mirrors the real anatomical structure, allowing surgeons to practice and plan procedures in a realistic virtual environment before performing actual surgery. This copying approach maintains surgical precision while improving realism by accurately reproducing patient-specific anatomy.
Solution Approach 2:
The patent transforms 2D medical imaging data into 3D models by changing the dimensional parameters of the representation. This parameter transformation enables the creation of realistic three-dimensional surgical simulations from conventional two-dimensional imaging, thereby improving both surgical precision and realism simultaneously.
2Measurement precision
If a virtual simulation surgery is performed, then surgical planning accuracy is improved, but the ability to replicate actual surgical conditions deteriorates
Solution Approach 1:
The patent applies local quality by creating patient-specific 3D models that accurately represent the unique anatomical characteristics of each patient's surgical site. Rather than using generic models, the system tailors the virtual simulation to match the specific local conditions of the individual patient, including organ positions, blood vessel locations, and tissue properties, thereby improving both diagnostic accuracy and condition matching.
Solution Approach 2:
The patent performs preliminary 3D modeling and simulation preparation before the actual surgery. By creating the virtual surgical environment in advance with patient-specific anatomical data, the system enables surgeons to plan and rehearse procedures under conditions that closely match the actual surgery, improving both measurement precision and adaptability to actual surgical conditions.

AI summary
A method for providing a patient-specific 3D surgical simulation method, according to the present invention, may comprise the steps of: acquiring a scan image including an image of a target object outputted by scanning a patient's body; identifying images of the target object and one or more organs and blood vessels adjacent to the target object in the scan image; generating a first 3D model of a surgical area on the basis of first 3D modeling data of the identified image and second 3D modeling data related to the one or more organs and blood vessels; setting third 3D modeling data and environmental variables for surgical equipment to be applied to the first 3D model; generating a second 3D model for the surgical equipment on the basis of the third 3D modeling data and the environmental variables; and providing a patient-specific surgical simulation on the basis of the first 3D model and the second 3D model.
