Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of the gantry and robotic arm in existing X-ray computed tomography (CT) systems can limit access to various surgical locations on a patient, making it difficult to perform surgeries in thoracic, abdominal, and other cavities.
Innovation Solution
A system comprising a gantry with a CT imaging device, a platform supporting the gantry, and a robotic arm assembly attached via a pivot arm, allowing for multiple positioning options to enhance access to different parts of the patient's body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic arm is added to a CT system for surgical assistance, then surgical functionality is improved, but the arrangement complexity and access difficulty increase
Solution Approach 1:
The robotic arm is positioned above the patient rather than beside them, utilizing the vertical dimension to access surgical sites without interfering with the CT gantry's horizontal movement and imaging path. This overhead configuration allows simultaneous CT scanning and robotic surgical intervention without spatial conflict.
Solution Approach 2:
The system divides the surgical and imaging functions into separate modular components: the CT gantry for imaging, the robotic arm for surgical intervention, and the overhead positioning system. This segmentation allows each component to operate independently while contributing to the overall surgical process.
2Ease of operation
If the robotic arm is positioned to access surgical sites, then surgical accessibility is improved, but the gantry movement and imaging capability are restricted
Solution Approach 1:
By positioning the robotic arm from above the patient, the system creates a three-dimensional workspace that does not conflict with the CT gantry's horizontal scanning motion. The robotic arm can reach various surgical sites vertically while the gantry moves horizontally for imaging.
Solution Approach 2:
The robotic arm is designed with multiple degrees of freedom and adjustable positioning capabilities, allowing it to dynamically adapt its position and angle to access different surgical sites without restricting the gantry's movement range or imaging trajectory.
3Manufacturing precision
If multiple positioning options are provided for the robotic arm, then surgical precision is improved, but the system complexity increases
Solution Approach 1:
The robotic arm incorporates multiple adjustable joints and positioning mechanisms that allow dynamic reconfiguration for different surgical approaches. These dynamic positioning options enable precise access to various anatomical locations while maintaining system manageability through controlled degrees of freedom.

AI summary
A system for performing robotic surgery on a patient disposed on a bed includes a gantry comprising a computed tomography (CT) diagnostic device, a platform supporting the gantry, and a robotic arm assembly attached to the platform. The gantry slides along the platform via a first carriage to allow entry of at least part of the patient into the bore of the CT device. The robotic arm assembly is attached to the platform via a pivot arm and a second carriage to allow the assembly to slide along the platform to enable surgery to be performed on the patient. The pivot arm is substantially parallel to the upper surface of the platform.
