Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of surgical assets, particularly non-sterile implants, is challenging due to space constraints, lack of standardization, and compatibility issues with existing asset identification systems, leading to inefficiencies and increased costs in surgical environments.
Innovation Solution
A system using a combination of human-readable and machine-readable asset identification objects, including laser-engraved metal stickers and unique tray identifiers, enables efficient tracking and management of surgical assets by eliminating the need for complex manual data entry and reducing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If asset identification objects are placed on or near small non-sterile implants, then automated identification and tracking can be achieved, but the limited space on surgical trays prevents adequate placement of additional identification objects
Solution Approach 1:
The patent divides the identification system into two segments: tray-level identification objects that identify the entire tray contents, and asset-level identification objects that identify individual items. This segmentation allows the tray identifier to serve multiple assets simultaneously, reducing the number of individual asset identifiers needed and thus minimizing space consumption on the tray while maintaining automated tracking capability.
Solution Approach 2:
The tray identification object acts as an intermediary that provides a unique identifier for the tray and its contents. By scanning the tray identifier, the system can retrieve information about all assets on the tray without requiring each asset to have its own identifier physically present on the tray. This intermediary approach enables automated tracking while conserving tray space.
2Ease of operation
If manual documentation processes are used for tracking implant usage, then flexibility in recording is maintained, but the process is time-consuming and prone to human error
Solution Approach 1:
The system implements automated feedback loops where scanning the tray identifier and asset identifiers triggers automatic data entry into the documentation system. The system provides real-time feedback by automatically recording implant usage, eliminating manual transcription steps, and reducing human error while maintaining operational flexibility through the automated interface.
Solution Approach 2:
The patent replaces the mechanical manual documentation process with an automated electronic system. Instead of manually transcribing and entering data, the system uses optical scanners and computer-automated data capture to replace manual writing and typing operations, significantly increasing productivity while reducing errors.
3Extent of automation
If existing trays are retrofitted with asset identification objects, then automated tracking can be implemented, but the process is cumbersome and costly with hundreds of thousands of trays in the field
Solution Approach 1:
The tray identification object is designed as a universal component that can be applied to any surgical tray regardless of its original configuration. The single-sided RFID tag design provides multi-functionality by serving as both the tray identifier and a potential asset identifier reference point. This universality simplifies the retrofit process compared to modifying complex multi-component systems.
Solution Approach 2:
The patent changes the parameter of identification object placement from requiring multiple objects distributed across the tray to using a single tray-level identifier. This parameter change fundamentally simplifies the retrofit process by eliminating the need to modify or reconfigure existing tray structures, allowing simple attachment of the RFID tag without complex assembly procedures.
4Measurement precision
If multiple asset identification objects are placed on trays, then comprehensive tracking of individual assets is achieved, but compatibility issues arise between different systems and technologies
Solution Approach 1:
The patent employs homogeneity by using RFID technology as a uniform standard across all identification objects. The single-sided RFID tags provide consistent, standardized identification that is compatible with various reading devices and systems. This homogeneous approach eliminates compatibility issues that would arise from mixing different identification technologies (barcodes, optical codes, magnetic tags) while maintaining precise asset tracking capability.

AI summary
A system and method identify and track surgical assets on surgical trays using a combination of human-readable primary asset identification objects and unique tray identifiers. The human-readable primary asset identification objects, such as laser-engraved metal stickers, are affixed to the trays and feature short, easily-readable asset identifiers such as numbers or letters. Similarly, secondary asset identification objects may provide additional identifiers that, when combined with primary asset identifiers, enhance the specificity of asset identification. These identifiers are minimal in information content, facilitating quick and error-free human readability. Each tray is associated with a unique tray identification object that is machine-readable, containing a unique identifier for the tray. The (primary or primary and secondary) asset identifiers on the human-readable objects, when combined with the tray's unique identifier, create a globally unique identifier for each asset. This unique identifier system allows for efficient tracking and management of surgical assets without the need for repeatedly reading the tray identifier for each asset on the tray.
