Hinged Surgery Table With Length Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgery tables lack the ability to efficiently position patients in various angles and orientations, particularly for back surgery, while minimizing frictional dragging and pinch points, and do not effectively support natural spine biomechanics or facilitate X-ray device use during procedures.
Innovation Solution
A two-part hinged surgery table with a length compensation mechanism, pivot, and roll drive, featuring a slidable platform and motorized adjustment to allow for angulated positioning, reduce friction, and support upper body movement, incorporating wheels for mobility and stability, and designed to accommodate X-ray devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed surgery table is used, then the structure is simple and stable, but the patient cannot be positioned in various angles and orientations for different surgical procedures
Solution Approach 1:
The surgery table is divided into multiple independent sections (head section, torso section, leg section) that can be independently positioned and angled. Each section can be adjusted relative to others, enabling diverse patient positioning for different surgical procedures while maintaining manageable structural complexity through modular design
Solution Approach 2:
The table incorporates motorized actuators and drive mechanisms that enable dynamic adjustment of each section's position and angle. This allows the table to adapt to various surgical requirements by actively changing configuration, transforming a static structure into a versatile, programmable positioning system
2Productivity
If manual positioning with pillows and pads is used, then the device complexity is low, but the positioning efficiency and precision are insufficient
Solution Approach 1:
Manual positioning using pillows and pads is replaced with an automated motorized system. Electric actuators control the positioning of table sections through programmed sequences, dramatically improving positioning efficiency and precision while reducing human labor and variability in the positioning process
Solution Approach 2:
The system enables precise control of positioning parameters such as section angles, elevations, and relative positions through motorized adjustment. This allows for exact reproduction of required positions and efficient transitions between different surgical configurations, overcoming the imprecision of manual padding methods
3Adaptability or versatility
If a hinged two-section table is used to enable articulation, then patient positioning for back surgery is improved, but the device complexity increases
Solution Approach 1:
The table is divided into two main hinged sections that can articulate relative to each other, creating a flexible configuration for back surgery and other procedures requiring non-linear positioning. This segmentation enables the articulation capability while keeping each section's internal structure relatively simple
Solution Approach 2:
The hinge mechanism acts as an intermediary joint between table sections, providing the necessary articulation while incorporating drive mechanisms and positioning controls that manage the complexity of the articulation function through specialized subsystems
4Object-affected harmful factors
If frictional dragging is minimized through surface treatment, then patient comfort is improved, but the manufacturing complexity increases
Solution Approach 1:
The surface properties of the table are modified through treatment processes that change friction parameters. Low-friction coatings or textured surfaces are applied to contact areas to minimize dragging on patient skin and clothing, improving comfort while using established manufacturing techniques to control production complexity

AI summary
A surgery table utilizing first and second sections which are hingedly attached to one another. First and second sections are also connected to supports apart from the hinged portion. An elevator moves one of the sections upwardly and downwardly at the support. The resultant position of the frame formed by the first and second sections may take the configuration of a flat surface or an upwardly or downwardly oriented “vee”.
