Modular Surgical Instrument Coupling for Robotic-Manual Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical instruments lack modularity and reusability, limiting their versatility and adaptability in surgical robotics, particularly in scenarios where human intervention is necessary due to robot malfunction or preference for manual operation.
Innovation Solution
A modular manipulation module for surgical instruments that allows for detachable coupling with an instrument module, enabling user-controlled motion of end tools through a power connection part, which transmits driving forces for yaw and pitch rotations, and includes a handle for manual operation, facilitating integration with surgical robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If surgical instruments are designed as integrated non-modular systems, then structural simplicity is maintained, but versatility and reusability are limited
Solution Approach 1:
The surgical instrument is divided into separate modular components: a manipulation module containing the handle and power connection part, and an instrument module containing the end tool and driving members. These modules can be detachably coupled or separated, allowing the system to adapt to different surgical needs while maintaining structural simplicity within each module.
Solution Approach 2:
The manipulation module is designed with a standardized power connection part that can interface with different instrument modules, enabling a single manipulation module to control various end tools (graspers, cutters, staplers). This multi-functionality increases versatility without requiring each configuration to be a complete separate instrument.
2Adaptability or versatility
If surgical instruments are designed as fixed non-detachable systems, then operational reliability is maintained, but reusability and adaptability are reduced
Solution Approach 1:
The connection between the manipulation module and instrument module transitions from static fixed coupling to dynamic detachable coupling. The power connection part includes engagement features that provide reliable mechanical and electrical connections when coupled, while allowing easy separation when needed, thus enabling reusability without compromising operational reliability during use.
3Adaptability or versatility
If modular manipulation modules with detachable coupling are implemented, then versatility and reusability are enhanced, but device complexity increases
Solution Approach 1:
By segmenting the surgical instrument into standardized modules with clear interfaces, the complexity of adaptability is managed through modular architecture rather than complex integrated designs. Each module remains relatively simple, and the overall system achieves high adaptability through the combination of standardized modules.
4Productivity
If integrated surgical instruments are used, then ease of manufacture is maintained, but productivity and surgical efficiency are limited
Solution Approach 1:
The manipulation module and instrument module can be manufactured separately using optimized processes for each component, then assembled through the detachable power connection interface. This segmentation allows parallel manufacturing and inventory management of different instrument modules, improving surgical efficiency by enabling quick changes between tools without complex remanufacturing.
