Surgical Table Stabilization via Upward Force Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical tables often vibrate and shift during robotic surgical procedures, interfering with the precise control needed for successful operations when robotic surgical arms are mounted on mobile carts that do not share a common surgical coordinate space with the table.
Innovation Solution
A method and system that stabilize the surgical table using a table support element on a mobile surgical cart, applying a controlled upward force to the table's underside to reduce vibrations and unintended movements, allowing for precise robotic surgery while allowing the table's position and orientation to be adjusted during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If robotic surgical arms are mounted on mobile carts that can be moved in and out proximity with the surgical table, then the system provides mobility and flexibility, but the surgical table vibrates and shifts position relative to the robotic surgical arms, interfering with precise control
Solution Approach 1:
A support element is introduced as an intermediary component between the mobile robotic cart and the surgical table. This support element transfers and distributes the weight and forces from the robotic cart to the surgical table, creating a stable mechanical connection that eliminates vibrations and position shifts while preserving the mobility of the cart system.
2Manufacturing precision
If the surgical table is stabilized to reduce vibrations, then precise control of surgical tools is enabled, but the ability to change position and orientation of the bed during the procedure is restricted
Solution Approach 1:
The support element is designed with dynamic characteristics that allow it to adapt to different operational states. During stable positioning, the support element maintains rigid contact to eliminate vibrations. When position adjustment is required, the system can dynamically respond by allowing controlled movement while maintaining stability, thus providing both precision and adaptability.

AI summary
A robotic surgical system comprises a mobile cart, a first surgical robotic arm, a table support element, and a surgical robotic controller. The first surgical robotic arm is located on the mobile cart and holds a first surgical tool. The surgical robotic controller elevates the table support element to engage and to apply a controlled upward force to a structure on an underside of the surgical table to stabilize the surgical table.
