Solution Overview

Problem

Existing staple insertion kits often require significant effort to reattach or redeploy staples after initial use, limiting their reusability and necessitating additional implants.

Innovation Solution

A compression staple insertion kit with pivotally attached handle arms, a slider, and bosses that allows for staple pre-loading and secure release, enabling easy insertion and potential reattachment of the staple inserter to the staple, facilitating efficient reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional staple inserters are used, then staple insertion can be performed, but the inserter cannot be reattached to the staple after deployment, requiring great effort to redeploy or necessitating another implant

Engineering Contradiction:

Improveease of staple redeploymentVSAvoidcomplexity of reattachment mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The inserter is divided into separate components: a handle assembly and a staple assembly. The handle contains a receiver that can receive the staple, allowing the inserter to be segmented into reusable handle and disposable staple portions, enabling easy redeployment without complex reattachment mechanisms

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The staple is nested within the handle assembly during storage and transport. The receiver in the handle is designed to accommodate the staple in a pre-loaded configuration, allowing the inserter to be reconfigured by simply removing and replacing the staple portion without complex assembly steps

Inventive Principle:

Principle #7Nested doll (Nesting)

2Productivity

If staples are pre-loaded onto the inserter, then insertion efficiency is improved, but the inability to reattach limits reusability

Engineering Contradiction:

Improvestaple insertion efficiencyVSAvoidreusability of inserter

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The staple is pre-loaded onto the inserter handle during manufacturing, so that when the kit is used, the staple is already positioned and ready for insertion. This preliminary action eliminates the need for intraoperative loading, improving efficiency while the modular design maintains reusability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The staple is designed as a disposable component that is discarded after use, while the handle assembly is recovered and reused. The receiver in the handle is designed to easily accommodate a new staple portion, allowing the majority of the inserter system to be recovered and reused without complex reattachment procedures

Inventive Principle:

Principle #34Discarding and recovering

AI summary

A compression staple insertion kit includes first and second elongate handles, each including a handle arm having a proximal end and a distal end, distal from the proximal end. A boss extend is outwardly from the distal end. A central longitudinal axis extends between the arms. The handle arms are pivotally attached to each other at the distal ends at a pivot, which extends along the central longitudinal axis. A slider is slidingly attached to the handle. The slider is movable between a staple securing position at the distal end, wherein proximal ends are biased toward each other and a staple release position toward the proximal end, wherein the proximal ends are biased away from each other. A staple is disposed over the bosses.
