Robotic Surgical Stapler Assembly for Universal Reload Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hospitals face additional expenses and resource management challenges due to the need to stock multiple types of replaceable surgical stapler cartridges for different surgical staplers, including hand-held and telesurgical robotic systems, leading to increased inventory and training complexities.
Innovation Solution
A robotic surgical assembly that detachably mounts to a surgical robot, utilizing a common replaceable stapler cartridge compatible with both hand-held and robotic systems, reducing the need for multiple cartridge types by enabling a single cartridge to be used across different stapler configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of replaceable stapler cartridges are stocked for different surgical staplers, then compatibility with various surgical systems is improved, but inventory complexity and expense increase
Solution Approach 1:
The robotic surgical stapler is designed to accept the same replaceable stapler cartridge as hand-held surgical staplers, creating a universal cartridge interface that works across different surgical systems. This allows a single cartridge design to serve multiple functions and systems, eliminating the need for system-specific cartridges.
2Adaptability or versatility
If different types of replaceable stapler cartridges are stocked for different surgical staplers, then compatibility with various surgical systems is improved, but training requirements increase
Solution Approach 1:
By designing the robotic surgical stapler to use the same replaceable cartridge as hand-held staplers, the system creates a universal interface that reduces training requirements. Surgical staff trained on hand-held staplers can transfer their skills to the robotic system without additional specialized training on cartridge loading and operation.
3Reliability
If multiple types of stapler cartridges are maintained, then system-specific optimization is improved, but resource management becomes more difficult
Solution Approach 1:
The invention merges the cartridge design of hand-held and robotic surgical staplers into a single unified replaceable cartridge system. This consolidation simplifies resource management by reducing the number of cartridge types that need to be tracked, stored, and managed, while maintaining system-specific optimization through the robotic stapler's control system.
