Adapter device for an operating table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapter devices for operating tables are either limited to accommodating a single piece of auxiliary equipment or are rigidly connected to the table, requiring time-consuming individual adjustments when the table segments are adjusted, and are impractical for precise positioning under sterile cloths.
Innovation Solution
A detachable adapter device with a pivoting joint and clamping mechanism that allows multiple auxiliary equipment to be easily and quickly adjusted and aligned on segmented operating table side rails, featuring a lockable hinge and adjustable degrees of freedom for flexible positioning and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If auxiliary equipment is rigidly connected to the operating table, then the equipment remains stable and securely positioned, but it cannot be easily adjusted when table segments are repositioned
Solution Approach 1:
The adapter device incorporates a ball joint that allows dynamic adjustment of the auxiliary equipment position. The ball joint enables the adapter to pivot and adapt to different angular positions of table segments while maintaining secure attachment. This dynamic capability resolves the contradiction by allowing both easy adjustment and reliable positioning.
Solution Approach 2:
The adapter device is designed as a separate, detachable component that bridges the auxiliary equipment and the operating table. This segmentation allows the adapter to be independently adjusted relative to both the table and the equipment, enabling easy repositioning when table segments are moved while maintaining secure connections on both sides.
2Measurement precision
If vises with adjusting options are used for each piece of auxiliary equipment, then individual positioning is possible, but each piece requires separate adjustment which is time-consuming
Solution Approach 1:
The adapter device combines multiple adjustment functions into a single unified mechanism. The ball joint provides both angular adjustment for the adapter relative to the table and positioning adjustment for the auxiliary equipment on the adapter, eliminating the need for separate vises on each equipment piece and reducing adjustment time while maintaining precision.
Solution Approach 2:
The adapter device serves multiple functions: it attaches to the operating table, provides angular adjustment for table segment changes, and positions the auxiliary equipment. This multi-functionality in a single device eliminates the need for multiple separate adjustment mechanisms, resolving the time-consuming adjustment problem.
3Adaptability or versatility
If auxiliary equipment is arranged on segmented table rails, then the equipment can be positioned for different surgical configurations, but adjustments produce corresponding changes that may displace equipment from its adjusted position
Solution Approach 1:
The ball joint in the adapter device provides dynamic compensation for table segment movements. When table segments are repositioned for different surgical configurations, the ball joint allows the adapter to pivot and maintain the auxiliary equipment in its adjusted position, preventing displacement while enabling adaptability.
Solution Approach 2:
The adapter device acts as an intermediary between the segmented table rail and the auxiliary equipment. It decouples the positioning relationship, allowing the table segments to move for different configurations while the adapter maintains the equipment's adjusted position through its pivoting capability.

AI summary
An adapter device for detachably fastening instruments and equipment to a side rail of an operating table includes a clamping device by means of which the adapter device can be clamped to the side rail of the operating table, a longitudinal profile onto which the instruments and equipment can be detachably fastened, and a joint having at least one pivot axis formed between the clamping device and the longitudinal profile so that the longitudinal profile is pivotable relative to the clamping device about the pivot axis of the joint.
