Adjustable Support Bracket for Spine Surgery Table Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical patient support systems face challenges in safely and efficiently positioning patients in multiple body positions during surgery, particularly in transitioning between lateral and prone positions, which is crucial for accessing various surgical sites while ensuring patient safety and surgical access.
Innovation Solution
A surgical patient support system comprising a tower base, main brackets, and patient support tops that allow for controlled translatable and rotational movement, enabling the patient to be securely positioned in lateral and prone positions through adjustable brackets and a transfer sheet, with features like a break assist bladder for leg positioning and axilla support, facilitating smooth transitions between positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a surgical patient support system uses fixed support brackets to hold the patient support top, then the structural stability is improved, but the ability to transition between lateral and prone positions is worsened
Solution Approach 1:
The support bracket is designed with a rotor and adjustment supports that can be selectively positioned at different angular and radial positions. The adjustment supports can rotate relative to the rotor and be locked at various angles, enabling the bracket to adapt between holding the patient support top in lateral position or transitioning to prone position. This dynamic adjustability resolves the contradiction between structural stability and position transition capability.
2Ease of operation
If the support bracket allows angular and radial adjustment of the patient support top, then the ease of operation for positioning is improved, but the device complexity increases
Solution Approach 1:
The support bracket is divided into distinct functional components: a rotor for angular adjustment, adjustment supports for radial positioning, and locking mechanisms for securing positions. Each component has a specific function, allowing independent adjustment of angular and radial positions. This segmentation enables complex positioning capabilities while keeping each individual component relatively simple and manageable.
3Reliability
If the patient support top is securely fixed during surgery, then the patient safety is improved, but the ability to reposition the patient for different surgical accesses is worsened
Solution Approach 1:
The support bracket includes locking mechanisms that can securely fix the patient support top in a desired position once adjusted. The adjustment supports can be locked at specific angular positions relative to the rotor, providing preliminary secure fixation. This allows the patient to be safely positioned for a surgical procedure while maintaining the capability to unlock and reposition if different surgical access is needed, thus resolving the contradiction between patient safety and repositioning capability.
