Synchronous Pedal Base Mechanism for Stable Surgical Robot Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doctor-controlled platform bases for surgical robots have complex control mechanisms for locking the platform and adjusting the pedal base, leading to discomfort and instability during operation.
Innovation Solution
A doctor-controlled platform base with a U-shaped base, synchronous pedal assemblies, a control pedal assembly, and a brake assembly, where the synchronous pedal assemblies move up or down synchronously to drive the control pedal assembly and brake assembly, simplifying the control mechanism and improving comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate control mechanisms are used for locking the platform and adjusting the pedal base, then the platform can be locked stably and the pedal can be adjusted, but the equipment structure becomes complex
Solution Approach 1:
The patent combines two separate control mechanisms into one integrated mechanism. The single control mechanism includes a control pedal that simultaneously controls both the platform locking function and the pedal base adjustment function, reducing structural complexity while maintaining both functions
Solution Approach 2:
The control mechanism is designed with multi-functionality, where one mechanism performs multiple functions: locking the platform and adjusting the pedal base height. This is achieved through a universal control structure that can switch between different functions based on operational needs
2Device complexity
If the pedal base is maintained at a high-level position without an up-down mechanism, then the structure is simpler, but the surgeon's leg and foot are suspended from the ground causing discomfort
Solution Approach 1:
The up-down adjustment mechanism for the pedal base is merged with the platform locking mechanism into a single integrated control system. This allows the pedal base to be adjusted to a comfortable height while using the same control structure as the platform locking, maintaining structural simplicity
Solution Approach 2:
The pedal base is designed with dynamic adjustability, allowing it to change height based on operational requirements. The pedal base can be adjusted to a lower position during surgery to provide support for the surgeon's foot, improving comfort while maintaining a relatively simple structure

AI summary
A doctor-controlled platform base, comprising a base, synchronous pedal assemblies arranged at bottom of the base, a control pedal assembly and a brake assembly; the control pedal assembly is connected under the base, and is connected to the synchronous pedal assemblies; a walking device is arranged below the base; one end of the brake assembly is hingedly connected to the control pedal assembly, and the other end is connected to the walking device; when at least one synchronous pedal assembly is subjected to an external force, the two synchronous pedal assemblies ascend and descend synchronously, driving the control pedal assembly to ascend and descend in the same direction; when ascending and descending, the control pedal assembly can drive the brake assembly to move to lock or loosen the walking device. The synchronous pedal assemblies can be stabilized at the highest stable point or the lowest stable point.
