Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical staplers lack the capability to provide multi-sized staple legs within a single device, leading to suboptimal tissue alignment and cosmetically less appealing outcomes, and are inefficient in complex surgical scenarios.
Innovation Solution
A medical stapler with a four-legged staple design featuring fine and standard legs, allowing for staggered release and independent deployment, combined with a single-track dispensing mechanism for simultaneous closure of superficial and deeper tissue layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional staplers use single-sized staple legs, then the device structure is simple, but tissue alignment is suboptimal and cosmetic outcome is less appealing
Solution Approach 1:
The staple is divided into multiple legs of different sizes (first size and second size) within a single staple assembly. This segmentation allows different tissue layers to be closed with appropriately sized legs, improving tissue alignment precision while maintaining a unified staple structure that doesn't excessively increase device complexity.
Solution Approach 2:
Different portions of the staple (different legs) are designed with different local qualities (different sizes) to match the specific requirements of different tissue layers. The first size legs address superficial layers while the second size legs address deeper layers, optimizing local tissue closure characteristics.
2Productivity
If traditional suturing is used for wound closure, then adaptability to different tissue types is high, but procedural time is extended
Solution Approach 1:
Multiple staple legs of different sizes are merged into a single staple assembly that can be deployed simultaneously through one firing action. This combines the functionality of multiple individual stapling operations into a single action, dramatically increasing closure procedure speed while the integrated design keeps the mechanism complexity manageable.
Solution Approach 2:
The staple assembly is pre-configured with multiple legs of different sizes positioned and oriented before deployment. This preliminary arrangement eliminates the need for sequential adjustment or individual leg deployment, allowing all legs to engage tissue simultaneously upon firing, thus maximizing procedural efficiency.
3Manufacturing precision
If multi-sized staple legs are provided in a single device, then tissue alignment improves and cosmetic outcome enhances, but the device becomes more complex
Solution Approach 1:
The single staple assembly performs multiple functions by incorporating legs of different sizes, enabling it to close both superficial and deep tissue layers in one deployment. This multi-functionality achieves improved tissue alignment precision across different depths without requiring multiple separate devices or complex assembly mechanisms.

AI summary
The present invention introduces a medical stapler configured for efficient wound and incision closure with cosmetically appealing end result, Utilizing a four-legged staple and a single-track dispensing mechanism. The medical stapler enables rapid deployment of staples in a vertical mattress suture fashion, facilitating optimal tissue approximation without the requirement of suturing. The deployment mechanism is designed to affect a staggered release of the fine legs and the standard legs of each staple, thereby promoting engagement with superficial tissue layers and engagement with deeper tissue layers. Additionally, the staple assembly allows for independent deployment of the fine legs from the standard legs as needed, enhancing procedural efficiency and flexibility.
