Surgical Table Top Coupling With Single-Handle Lock Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical tables and other patient support apparatuses are often difficult to adjust prior to and during surgery, which can hinder proper patient positioning and stability.
Innovation Solution
A patient support apparatus incorporating a caster with a braking system and linkage mechanism that allows for controlled movement and locking of the caster wheels, enabling precise adjustment and stabilization of the patient support surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a surgical table allows adjustment of the table prior to surgery so that patients can be properly supported or held in place for a particular surgical operation, then patient positioning capability is improved, but the table becomes difficult to adjust prior to and/or during surgery
Solution Approach 1:
The patent applies dynamics by making the casting system movable between locked and unlocked states. The release mechanism allows the casting to transition from a fixed position (locked to the table) to a movable position (unlocked), enabling easy adjustment of the surgical table during surgery while maintaining stability when locked. This dynamic capability resolves the contradiction by allowing the table to be both adjustable and stable at different times.
2Stability of the object's composition
If a caster braking system is used to lock the wheel, then stability is improved, but the ability to quickly release for emergencies deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the release mechanism in a ready state that requires minimal action to activate. The release mechanism is designed so that the caster can be quickly unlocked with a simple pull or press action, without requiring complex disassembly or multiple steps. This preliminary preparation ensures that while the caster remains stable when locked, it can be rapidly released in emergencies or when adjustment is needed.

AI summary
A surgical patient support includes a foundation frame, a support top, and a brake system. The foundation frame includes a first column and a second column. The support top is coupled to the first column and the second column for rotation about a top axis extending along the length of the support top. A single-handle unlock for the support top is also provided.
