Pivoting Staging Tray Assembly for Surgeon Access During Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During surgical procedures, surgeons often face distractions as they need to request items from surgical technologists, as medical trays are typically positioned over the patient's chest, making it difficult for both the surgeon and technologist to access instruments and supplies simultaneously.
Innovation Solution
A staging tray assembly with a pivot mechanism, angular and linear adjustment systems, and a forceps receiver, allowing the tray to be positioned both angularly and linearly relative to a medical tray, enabling the surgeon to access necessary items without diverting attention from the procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the medical tray is positioned over the patient's chest for storage and placement of surgical items, then the surgical technologist can access items easily, but the surgeon cannot access items without being distracted from the procedure
Solution Approach 1:
The system divides the surgical tray functionality into two separate trays: a primary medical tray positioned over the patient's chest for the surgical technologist, and a secondary staging tray positioned within the surgeon's reach. This segmentation allows both users to access their respective trays simultaneously without interference, eliminating the need for the surgeon to be distracted from the procedure.
Solution Approach 2:
The bracket assembly acts as an intermediary structure that connects the staging tray to the medical tray. It provides a mechanical interface with pivot mechanisms and locking elements that enable the staging tray to be positioned and secured in an intermediate location between the medical tray and the surgeon, facilitating simultaneous access by both the surgeon and surgical technologist.
2Stability of the object's composition
If the medical tray is positioned in a fixed location over the patient's chest, then it provides stable storage, but it cannot be accessed by both the surgeon and surgical technologist simultaneously
Solution Approach 1:
The bracket assembly incorporates pivot mechanisms with locking elements that enable the staging tray to be dynamically positioned at various angles and locations relative to the medical tray. The locking elements secure the tray in desired positions, providing stability when needed while allowing repositioning when accessibility requirements change during the surgical procedure.
Solution Approach 2:
The system allows changing the positional parameters of the staging tray through the pivot mechanism, which can rotate the tray to different angles and positions. This enables the tray to adapt to different surgical scenarios and user needs while maintaining stable positioning when locked in place.
3Ease of operation
If a staging tray is added to enable surgeon access, then surgeon accessibility improves, but the device complexity increases with pivot mechanisms and locking elements
Solution Approach 1:
The locking elements are designed to be easily operated by the surgeon using one hand, allowing the surgeon to lock and unlock the staging tray position without requiring assistance from the surgical technologist. The mechanism serves itself by providing intuitive feedback and requiring minimal dexterity, reducing the operational burden despite the added complexity.

AI summary
A staging tray has a bracket with a hook and a bumper. The hook and bumper are configured to be removably engaged with a lipped tray. A pivot mechanism pivotably connects the bracket to the staging tray. The pivot mechanism is selectively positionable into a plurality of positions.
