Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgical instruments use traditional control systems, then the device structure is simple, but precision and adaptability in tissue manipulation are limited
Solution Approach 1:
The surgical instrument is divided into modular components including a handle assembly, shaft assembly, and end effector assembly that can be selectively attached and detached. This segmentation allows the complex control system to be distributed across modules while maintaining overall system precision.
Solution Approach 2:
The surgical instrument system is designed with multi-functional capabilities including grasping, dissecting, clipping, and suturing functions within a single integrated platform. The control circuit provides universal control across different end effectors and surgical tasks, improving precision without requiring separate specialized instruments for each function.
2Adaptability or versatility
If surgical instruments lack modular designs, then the device structure is simple, but versatility and adaptability are limited
Solution Approach 1:
The instrument comprises a handle assembly with drive module, a shaft assembly, and an end effector assembly that can be selectively attached to each other. This modular segmentation enables versatility by allowing different end effectors to be attached to the same handle and shaft assembly, while the mechanical coupling maintains structural simplicity.
Solution Approach 2:
The surgical instrument incorporates dynamic capabilities including articulation of the shaft assembly relative to the handle assembly and rotation of the end effector assembly. These dynamic features provide adaptability for different surgical approaches while maintaining a relatively simple modular structure that can be selectively configured.
