Surgical Instrument Case with Centralized Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical instrument trays and cases often clutter operating rooms and cause delays due to their design, requiring multiple trays and necessitating the use of two hands to lift and move them, making it difficult to find specific instruments efficiently.
Innovation Solution
A surgical instrument tray assembly with an outer case, inner tray, and handle, where the handle is securely coupled to the inner tray or case lid, allowing the assembly to be transported with a single hand by engaging the handle, which is positioned at or near the gravitational center for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple trays and cases are used to organize surgical instruments, then instrument organization and storage capacity are improved, but operating room clutter and time to locate instruments increase
Solution Approach 1:
The patent implements nesting by placing multiple inner trays within a single outer case. Each inner tray can be independently removed and used, while the case provides centralized storage. This allows all instruments to be organized in one location rather than scattered across multiple cases, reducing clutter and making it easier to locate instruments by accessing only the specific inner tray needed.
2Stability of the object's composition
If handles are attached to outside ends or sides of trays, then structural stability is maintained, but single-handed transport becomes impossible
Solution Approach 1:
The patent merges the handle function with the case structure by attaching the handle to the case rather than to individual inner trays. This integration allows the handle to serve the entire assembly, enabling single-handed transport of the case while the inner trays remain securely nested within. The handle becomes a unified component that stabilizes and controls the movement of the entire instrument storage system.

AI summary
A surgical instrument tray assembly according to the principles of the present disclosure includes an outer case, an inner tray, and a handle. The inner tray is configured to fit within the outer case and is releasably attached to the outer case. The handle is securely coupled to the inner tray such that the surgical instrument tray assembly, including the outer case and the inner tray, is transportable with a single hand by engaging the handle.
