Spine Table H-Bracket Guide for Arcuate Leg Support Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient support apparatuses during surgery often pose challenges in safely and efficiently repositioning patients between lateral, prone, and supine positions, which can be dangerous and difficult for caregivers, limiting accessibility for surgeons.
Innovation Solution
A patient support apparatus with a foundation frame, a base beam, a leg support, and a guide that allows the leg support to pivot along an arcuate path, enabling secure positioning changes through the use of adapters, torso supports, and a vacuum bag system for immobilizing the patient, facilitating safe and controlled repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the patient is repositioned on different patient supports or the same patient support, then surgical accessibility is improved, but patient safety and caregiver difficulty worsen
Solution Approach 1:
The patient support apparatus is designed to perform multiple functions: it can support the patient in lateral position, then reposition to prone or supine positions, and provide immobilization through vacuum bag system. This multi-functional design eliminates the need to transfer the patient to different supports, thereby improving surgical accessibility while maintaining patient safety through controlled repositioning on a single integrated support system.
2Adaptability or versatility
If the patient is repositioned on different patient supports or the same patient support, then surgical accessibility is improved, but caregiver difficulty worsens
Solution Approach 1:
The integrated patient support apparatus provides multiple positioning functions (lateral, prone, supine) on a single platform, eliminating complex transfer operations between different supports. This reduces caregiver difficulty while maintaining surgical accessibility.
Solution Approach 2:
The apparatus incorporates movable components including the leg support that can pivot along an arcuate path, and the vacuum bag system that can be inflated or deflated to adjust immobilization. These dynamic features allow smooth transitions between positions, making repositioning easier for caregivers while ensuring secure patient positioning for surgical access.
3Adaptability or versatility
If the leg support pivots relative to the base beam, then patient positioning flexibility is improved, but structural complexity increases
Solution Approach 1:
The leg support is designed to pivot relative to the base beam along an arcuate path, providing dynamic adjustment capability for patient positioning. This single pivoting mechanism achieves multiple positioning configurations without requiring complex multi-axis actuators or sophisticated control systems, thus improving positioning flexibility while limiting structural complexity to an manageable level.

AI summary
A patient support for use with a foundation frame is disclosed. The foundation frame includes a first column and a second column. The patient support includes a base beam, a leg support, and a guide. The base beam is coupleable to the foundation frame to be supported by the first column and the second column. The leg support has a first end pivotably coupled to the base beam and a second end spaced apart from the first end. The, guide is coupled to the base beam and to the second end of the leg support. The guide is configured to guide the second end of the leg support along an arcuate path when the leg support pivots relative to the base beam
