Surgical Return Packaging for Sterile Instrument Reclamation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of maintaining sterility in surgical environments while managing and processing surgical instruments, particularly during and after procedures, is complicated by the need to handle and dispose of instruments that may have contacted patients, leading to potential contamination and inefficiencies in waste management.
Innovation Solution
A modular surgical system with integrated sterilization and reclamation processes, including a hub enclosure for unified management of power, data, and fluid lines, and a surgical kit design that allows for easy separation and recycling of instrument components, using machine-readable tags for tracking and streamlined disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If surgical instruments are handled and disposed of after procedures, then waste management is achieved, but sterility is compromised and contamination risk increases
Solution Approach 1:
The surgical instrument is divided into multiple separable components including a reusable handle assembly and a disposable instrument assembly. This segmentation allows the disposable portion to be discarded after a single use, eliminating cross-contamination risks while maintaining sterility for the reusable portions through proper disposal of the disposable section.
Solution Approach 2:
The instrument incorporates a disposable instrument assembly that is designed for single-use only. This disposable component is discarded after one procedure, ensuring that no contamination can occur from repeated use, while the expensive reusable handle assembly can be sterilized and reused.
2Reliability
If surgical instruments are sterilized and reclaimed, then sterility is maintained, but handling complexity and processing time increase
Solution Approach 1:
By segmenting the instrument into reusable and disposable portions, the system simplifies sterilization processes. Only the handle assembly requires sterilization and reclamation procedures, while the disposable instrument assembly is discarded after use, reducing the overall complexity and time required for sterilization and handling.
Solution Approach 2:
The system implements a discard-and-recover strategy where the disposable instrument assembly is discarded after single use, and only the valuable reusable handle assembly is recovered, sterilized, and prepared for subsequent use. This approach maintains sterility while minimizing handling complexity.
3Productivity
If surgical instruments are designed for reuse, then cost efficiency improves, but contamination risk and sterilization requirements increase
Solution Approach 1:
The instrument is segmented into a reusable handle assembly and a disposable instrument assembly. This allows the expensive components to be reused multiple times after sterilization, improving cost efficiency, while the disposable portion is discarded after single use to eliminate contamination risks entirely.
Solution Approach 2:
The disposable instrument assembly is designed as a low-cost, single-use component that eliminates contamination concerns. While it is discarded after one use, the overall system remains cost-effective because the expensive reusable handle assembly can be used repeatedly.

AI summary
A surgical kit includes a surgical instrument, a packaging, and a return packaging. The packaging defines an interior and an exterior in a closed configuration. The surgical instrument is disposed within the interior of the packaging or coupled with the packaging in the closed configuration. The packaging is configured to transition to an open configuration by a user to expose the interior and allow for access of the surgical instrument during a surgical procedure. The return packaging is configured to receive at least a portion of the surgical instrument after the surgical procedure for reduced cross-contamination. The return packaging is at least one of coupled with the packaging or disposed within the interior in the closed configuration.
