Segmented Surgical Tool Packaging for Sterility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for surgical tools, such as cutting accessories, lead to surgical site infections (SSIs) due to contamination during handling and mounting on surgical devices, and they do not adequately prevent contact between the tool's sharp features and packaging.
Innovation Solution
A packaging system comprising a segmented packaging body with a distal casing that encases the tool's cutting bur and shaft portions, and a proximal section that receives the remaining shaft portion, all within a sealed pouch to maintain sterility and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tool is removed from packaging and placed on a table for mounting, then the tool can be accessed for mounting on the surgical device, but the risk of contamination increases due to physical handling and exposure
Solution Approach 1:
The packaging system employs nested packaging where the tool is placed within an inner sterile package, which is then placed within an outer protective package. This nested structure allows the tool to remain protected during handling while still being accessible for mounting through controlled access to the inner package.
Solution Approach 2:
The packaging system introduces an intermediary sterile barrier between the tool and the external environment. This sterile package acts as a mediator that allows tool access while preventing contamination from hands, surfaces, and air during the mounting process.
2Ease of operation
If the tool is handled by the user after removal from packaging, then the tool can be mounted on the surgical device, but surgical site infections may occur due to improper hand hygiene and pathogenic transference
Solution Approach 1:
The packaging system performs preliminary protective action by maintaining the tool in a sterile state within the packaging until the moment of mounting. The sterile package is prepared in advance and remains sealed, preventing any contact with pathogenic organisms before the controlled mounting process.
Solution Approach 2:
The sterile packaging acts as an intermediary barrier that eliminates the need for direct hand contact with the tool during mounting. The package can be opened in a controlled manner or the tool can be transferred through the package opening, serving as a mediator between the user's hands and the sterile tool.
3Object-affected harmful factors
If the tool remains in packaging during handling and transport, then contamination risk is reduced, but the tool cannot be accessed for mounting on the surgical device
Solution Approach 1:
The packaging system is segmented into multiple sections: a sealed inner sterile package containing the tool, and an outer protective package. This segmentation allows the inner package to remain sealed for contamination protection while the outer package can be opened for tool access. The segmented design enables selective access without compromising the sterile barrier.
Solution Approach 2:
The nested packaging structure allows the inner sterile package to remain intact and protected within the outer package. When tool access is needed, only the outer package needs to be opened, while the inner sterile package remains sealed until the moment of tool transfer, maintaining protection while enabling accessibility.
4Ease of operation
If the head of the cutting accessory contacts the packaging during handling, then the tool can be removed from packaging, but sharp features may remove packaging bits that contaminate the tool
Solution Approach 1:
The packaging system introduces an intermediary protective layer or barrier between the sharp cutting features and the packaging material. This intermediary element prevents direct contact between the sharp bur and the packaging, eliminating the risk of packaging bits being shaved off and contaminating the tool during removal.
Solution Approach 2:
The packaging employs flexible sterile barriers or films that can conform to the tool shape without being damaged by contact with sharp features. These flexible materials are designed to resist tearing or shedding when the tool is removed, preventing contamination while allowing easy tool extraction.

AI summary
A packaging body for use with an elongated tool that includes a distal cutting bur, a first shaft portion proximal to the distal cutting bur, and a second shaft portion extending from the first shaft portion. The packaging body has a distal casing with first and second distal sections. The distal sections each have a distal cavity being shaped to conform to the distal cutting bur and the first shaft portion. The distal sections are configured to couple to one another to collectively encase the distal cutting bur and the first shaft portion within the distal cavities. The packaging body includes a proximal section with a proximal cavity that is elongated and sized to receive the second shaft portion. A packaged tool assembly can include the packaging body that houses the elongated tool or a sealed pouch that includes the packaging body and the elongated tool disposed therein.
