Over-Table Robot Support Structure for Stable Robotic Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic surgery systems face challenges in providing a stable and rigid support for setup arms and surgical manipulators that minimizes movement relative to the surgical patient while maintaining an unobstructed workspace for surgical assistants, as conventional solutions either add bulk to the workspace or compromise stability by lengthening the support connection.
Innovation Solution
A robotic surgery system featuring a base with a vertically extending pillar, an attachment structure, and a patient table, along with a robot support arm that extends over the patient table to support a robotic surgical manipulator, providing a stiff and adjustable support system that minimizes movement and allows for flexible positioning of the patient and surgical instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional support structure is used for robotic surgical manipulators, then the workspace for surgical assistants remains unobstructed, but the stability and rigidity of the robot-patient connection is compromised
Solution Approach 1:
The patent combines the patient support table and robot support arm into a single integrated base structure. The base supports both the patient table and the robot support arm, creating a unified stable platform that eliminates the need for separate support structures while maintaining workspace accessibility.
Solution Approach 2:
The robot support arm extends in multiple dimensions - vertically upward from the base, then horizontally over the patient table. This multi-dimensional positioning allows the manipulator to reach the surgical site while keeping the base structure compact and the workspace unobstructed.
2Area of stationary object
If the support connection between robot and patient is lengthened to accommodate workspace requirements, then the workspace becomes more accessible, but the stiffness and stability of the system decreases
Solution Approach 1:
The robot support arm is divided into segmented sections with telescoping capabilities. This allows the arm to extend to the necessary length for workspace accessibility while maintaining structural integrity through multiple jointed sections rather than a single long rigid connection.
Solution Approach 2:
The support arm incorporates adjustable and telescoping connections that allow dynamic positioning. The arm can be extended or reconfigured based on surgical requirements, providing both the necessary reach for workspace access and the structural rigidity needed for stable manipulator positioning when in use.

AI summary
A robotic surgery system for supporting a patient and a robotic surgical manipulator. The robotic surgery system includes a base, a pillar coupled to the base at a first end and extending vertically upward to an opposing second end, and an attachment structure coupled to the second end of the pillar. A patient table is coupled to the attachment structure. A robot support arm has a first end coupled to the attachment structure. The robot support arm extends vertically upward and then horizontally over the patient table. A robotic surgical manipulator supported by the horizontal portion of the robot support arm will extend generally downward from the robot support arm toward a patient supported by the patient table to place an end effector of the robotic surgical manipulator adjacent a desired surgical site on the patient.
