Teleoperated Surgical Arm Mounting Device for Operating Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teleoperated surgical systems face challenges with limited movability, portability, and stability due to the mass of components, and existing operating tables are not designed to securely mount teleoperated surgical arms, leading to vibration and instability during procedures, while also being costly and complex.
Innovation Solution
A modular surgical system architecture with a mounting device that includes a coupler and support member for securing teleoperated surgical arms to operating tables, providing a stable and adjustable mounting system that reduces vibration and allows for efficient setup and storage, utilizing clamps and braces to reinforce the side rails and optionally include auxiliary rails for increased stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If teleoperated surgical arms are mounted on operating tables, then stability and vibration reduction are improved, but the operating table structure becomes more complex
Solution Approach 1:
The mounting system is segmented into separate components: a mounting device with coupler that attaches to the operating table, and a support member with brace that provides structural reinforcement. This segmentation allows the mounting function to be added without fundamentally redesigning the operating table structure.
Solution Approach 2:
The mounting device acts as an intermediary between the operating table and the surgical arm. It includes a coupler that interfaces with the table and a support member that provides the structural connection, thereby transferring loads while maintaining table integrity without requiring table modifications.
2Device complexity
If modular surgical system architecture is used, then cost and size are reduced, but system assembly and configuration complexity increases
Solution Approach 1:
The surgical system is divided into modular components: multiple independently mountable mounting devices, support members, and surgical arms. Each component can be manufactured separately and assembled as needed, allowing for reduced overall system size while maintaining ease of assembly through standardized interfaces.
Solution Approach 2:
The mounting devices and support members are designed with universal interfaces that can accommodate different surgical arms and configurations. The coupler and brace design allows the same mounting device to be used across different surgical scenarios, reducing the number of unique components needed and simplifying assembly procedures.
3Productivity
If surgical arms are mounted using side rails only, then setup speed is improved, but vibration and instability increase
Solution Approach 1:
The mounting system merges two support functions into one integrated solution: the coupler attaches to the side rail for quick positioning, while the support member with brace provides additional structural support. This combination achieves both rapid setup by utilizing existing rail infrastructure and enhanced stability through the added support member.
Solution Approach 2:
The support member extends in a dimension perpendicular to the side rail, creating a three-dimensional support structure. The brace reaches across the width of the operating table, adding a spatial dimension to the mounting that distributes loads more effectively and reduces vibration while maintaining quick setup capability.

AI summary
A medical device system includes: a surgical arm mounting device including a coupler and a surgical arm interface, the coupler including a clamp for a first side rail of an operating table; and a support member including a brace, the brace extending from the coupler at least part way across the width of an operating table. The clamp has a first mechanical state in which the mounting device is fixed to the side rail, a second mechanical state in which the mounting device is translatable along the side rail, and a third mechanical state in which the mounting device is removable from the side rail. The surgical arm interface is configured to receive a mating mounting device interface of a surgical arm.
