Folded Box-Shaped Surgical Staple for Small Port Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical staples for gastric volume reduction procedures are impractical due to their large size, material limitations, and inability to deploy a large number of staples through small diameter ports, leading to increased procedure time, complexity, and cost.
Innovation Solution
A low-profile surgical stapler that deploys folded, box-shaped staples with a closed loop configuration, capable of expanding to a wider form for increased tissue purchase, allowing multiple staples to be delivered through a small diameter port, facilitating efficient tissue folding in minimally invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional surgical staples are used for gastric volume reduction, then tissue purchase and fastening strength are adequate, but the staples are too large to be delivered through small diameter ports
Solution Approach 1:
The staple is designed in a nested, folded configuration where the legs are folded back against the body, creating a compact form factor that fits within small diameter ports while maintaining the ability to expand and engage tissue upon deployment
Solution Approach 2:
The staple transitions from a static, compact nested form during delivery to a dynamic, expanded form during deployment, allowing the same component to satisfy both small port requirements and adequate tissue purchase needs
2Productivity
If individual suture anchors are deployed manually through small ports, then tissue can be approximated, but the procedure becomes time intensive and complex
Solution Approach 1:
Multiple individual suture anchor operations are merged into a single stapling action, where one device deployment and firing event secures multiple tissue attachment points simultaneously, dramatically reducing procedure time and complexity
Solution Approach 2:
The stapling device performs multiple functions in a single operation: it deploys multiple staples, secures tissue at multiple locations, and creates approximations all through one port, eliminating the need for separate anchor deployment for each point

If a low profile stapler is used to deliver staples through small ports, then port size is reduced, but the stapler cannot deploy a large number of staples
Solution Approach 1:
Multiple staples are stacked nested within the stapler body in a compact arrangement, allowing a large quantity of staples to be stored and deployed through a low profile device without increasing the port diameter
Solution Approach 2:
The staple delivery system is segmented into multiple individual staples that can be stacked and deployed sequentially through the same low profile port, enabling multiple attachment points to be secured through repeated use of the compact device

AI summary
A surgical fastener applying device having a handle with a trigger pivotably attached thereto and movable within a trigger plane. The trigger has a bottom portion extending from the handle and a top portion disposed within a housing of the handle. The device has a staple housing with a proximal end attached to the handle, a distal end extending therefrom and a longitudinal axis therebetween. The housing has a firing bar disposed within, and the trigger is coupled to the firing bar. The device has a link member with a first end pivotably attached to the top portion of trigger, the link member has a second end comprising a slidable pin. The pin engages a three dimensional cam path disposed within the housing. The link member follows distal and proximal movement of the top portion of the trigger, and the pin slides perpendicular to the trigger plane to follow the three dimensional cam path.
