Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual determination and placement of mesh patch size and location is performed by the surgeon, then flexibility and adaptability to patient-specific anatomy is maintained, but the procedure becomes time-intensive and tedious
Solution Approach 1:
The system performs preliminary calculations and generates placement guidance parameters before the surgical procedure. Anatomical characteristic data is obtained and processed in advance to determine optimal mesh patch size, shape, and placement location, reducing the time needed during the actual surgery.
Solution Approach 2:
The computer-assisted surgical system acts as an intermediary between the surgeon and the mesh patch placement process. It automatically processes anatomical data, calculates placement parameters, and provides guidance to the surgeon, eliminating the need for manual measurement and calculation while maintaining surgical flexibility.
2Measurement precision
If manual sizing and cutting of the mesh patch is performed, then adaptability to specific anatomical requirements is maintained, but the process becomes time-consuming
Solution Approach 1:
The system replaces manual mechanical measurement and calculation with automated computer-based processing. Anatomical characteristic data is processed algorithmically to precisely determine mesh patch dimensions and placement parameters, eliminating time-consuming manual measurement while achieving accurate sizing.
Solution Approach 2:
The system automatically calculates and determines optimal mesh patch parameters (size, shape, placement location) based on processed anatomical characteristic data. These parameters are generated through computational algorithms that consider patient-specific anatomical requirements, ensuring precise mesh patch sizing without manual intervention.
3Manufacturing precision
If manual placement guidance is used, then surgical flexibility is maintained, but variance in suture spacing and placement consistency increases
Solution Approach 1:
The system provides real-time feedback to the surgeon through placement guidance parameters and visual guidance interfaces. This feedback mechanism ensures consistent and accurate mesh patch placement by continuously referencing pre-calculated optimal positions and suture spacing patterns, reducing variability in placement quality.
Solution Approach 2:
Suture spacing patterns and placement trajectories are pre-calculated and prepared before the surgical procedure. The system generates detailed placement guidance that specifies exact suture locations and spacing requirements, enabling the surgeon to follow a predetermined plan that ensures consistency and reduces intraoperative decision-making complexity.

AI summary
An exemplary system is configured to obtain anatomical characteristic data representative of a characteristic associated with an anatomical surface to be covered by a patch configured to cover a tissue defect, the anatomical surface within an internal space of a patient; and determine, based on the anatomical characteristic data, a placement guidance parameter set, the placement guidance parameter set comprising one or more parameters configured to guide a placement of the patch on the anatomical surface with one or more surgical instruments controlled by a computer-assisted surgical system.
