Slidable Instrument Tray Structure for Trendelenburg Surgery Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient protection devices for operating room tables do not adequately address the need for safe storage of surgical instruments while ensuring patient safety, especially during procedures that involve extreme Trendelenburg positions, and fail to provide efficient anesthesia access and exposure.
Innovation Solution
A patient protection device with a rigid support frame and a slidable receptacle tray that securely holds surgical instruments, allowing for easy access and positioning above the patient, and can be quickly reconfigured or removed for emergency access, featuring a pivotable design to accommodate different surgical table angles and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surgical instruments are stored on a traditional mayo stand, then instruments are readily accessible to the surgeon, but the patient is vulnerable to instrument dislodgment and injury during Trendelenburg positioning
Solution Approach 1:
The invention extracts the instrument storage function from the traditional mayo stand and relocates it to a protected position above the patient's head. The receptacle tray is separated from the support frame, allowing it to be positioned in a safe zone where instruments cannot dislodge onto the patient during Trendelenburg positioning, while maintaining accessibility through the slidable design.
Solution Approach 2:
The device is segmented into a rigid support frame and a separately mounted receptacle tray. This segmentation allows the tray to be positioned independently above the patient's head while the support frame remains anchored to the table, enabling instruments to be stored in a safe zone while maintaining accessibility.
2Stability of the object's composition
If the receptacle tray is fixed to the support frame, then instrument storage is stable, but emergency access to the patient is delayed
Solution Approach 1:
The receptacle tray is designed with dynamic mounting options - it can be securely fastened to the support frame for stable instrument storage during surgery, or quickly removed when emergency patient access is required. This dynamic capability allows the system to transition between stable storage and rapid access modes, resolving the contradiction between stability and emergency response time.
3Productivity
If the receptacle tray is positioned close to the surgical site for easy instrument access, then surgeon efficiency is improved, but anesthesia access to the patient's head is obstructed
Solution Approach 1:
The invention relocates the receptacle tray from the traditional horizontal position near the surgical site to a vertical position above the patient's head. This dimensional change allows instruments to be stored in the vertical space above the patient, keeping the horizontal workspace clear for anesthesia providers while maintaining instrument accessibility through the slidable tray design.
4Strength
If the support frame is designed to be rigid and fixed, then structural stability is ensured, but adaptability to different surgical table angles is reduced
Solution Approach 1:
The support frame incorporates adjustable legs with height adjustment capability, allowing the frame to adapt to different surgical table angles including Trendelenburg positions. The rigid structure provides structural stability while the adjustable components enable versatility across different surgical configurations, resolving the contradiction between strength and adaptability.

AI summary
A patient protection device is provided for an operating room table. A rigid support frame extends transversely over a top surface of said table, including a main body with an upper support surface and a pair of support legs that are secured to the table. A receptacle tray to receive medical equipment is securely mounted to the rigid support frame via a removable connection. The receptacle tray includes a first planar surface positioned above a body lying over said top surface of said operating room table. The receptacle tray is slidable, relative to the rigid support frame, along a direction substantially parallel to the upper support surface of the rigid support frame.
