Solution Overview

Problem

Existing packaging solutions for surgical sutures and needles often result in kinking, tangling, and inefficient dispensing during surgical procedures, which can complicate high-speed automated processes and increase the risk of complications.

Innovation Solution

A novel tray package design featuring a floor with radially extending platform sections, upwardly extending needle parks, and spiral suture tracks that allow individual suture strands to be mounted, preventing kinking and facilitating smooth dispensing, along with an optional rotation mechanism for easy access and handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional folder packages are used for sutures, then the packaging structure is simple and easy to manufacture, but the sutures may kink or take a set during storage and handling

Engineering Contradiction:
Improvepackaging structure simplicityVSAvoidsuture integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The package divides the suture storage space into multiple separate compartments or sections within the tray, allowing each suture to be individually positioned and supported. This segmentation prevents sutures from contacting each other in ways that cause kinking, while maintaining a relatively simple molded tray structure that is easy to manufacture.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple sutures are loaded into a folder package, then the quantity of sutures available for the procedure is increased, but tangling occurs between sutures

Engineering Contradiction:
Improvenumber of suturesVSAvoiddispensing ease
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The tray package incorporates multiple separate compartments or designated areas within the single tray structure, allowing multiple sutures to be stored simultaneously without contacting each other. Each compartment acts as an independent storage space that prevents tangling while maintaining compact packaging.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package uses vertical spacing and depth within the tray structure to separate sutures that would otherwise lie flat and tangle in a conventional folder. By utilizing the third dimension (depth/height) of the tray, multiple sutures can be stacked or positioned at different levels, preventing tangling while keeping them all accessible.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If tray packages are used for sutures, then kinking is prevented and automated loading is improved, but the device complexity increases compared to folder packages

Engineering Contradiction:
Improvesuture integrityVSAvoidpackage structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The package combines multiple functional elements into a single molded tray structure: the base tray, compartment walls, suture support surfaces, and needle retention features are all integrated into one piece. This merging reduces the number of separate components that would need to be assembled, simplifying manufacturing while maintaining the complex internal geometry needed to prevent kinking.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The tray structure performs multiple functions simultaneously: it provides structural support to prevent kinking, creates separate compartments to prevent tangling, retains needles in designated areas, and facilitates automated loading through its geometric features. This multi-functionality reduces the need for additional separate components, balancing reliability with manageable complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A novel suture tray package is disclosed. The package has a floor member and a plurality of curvilinear walls extending up from the top of the floor member and forming suture tracks. The walls extend in a spiral manner from the central section of the floor member to the periphery. Extending radially outwardly about the periphery are platform sections in communication with the tracks and optionally containing needle park members and pledget park members.
