Robotic Operating Table Translating Patient Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional patient placement tables in hybrid operating rooms have limited transverse movement, making it difficult to create sufficient space for surgeons and medical staff during procedures, especially when radiographic imaging is required, as they can only perform fine adjustments in the transverse direction, restricting the freedom of surgical operation positioning.
Innovation Solution
A robotic operating table with an articulated robotic arm that supports the patient placement table, allowing horizontal arrangement and translation within specific ranges to accommodate both imaging and surgical positions, providing increased freedom in positioning and space allocation for medical personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the operating table uses a conventional sliding mechanism on a fixed base, then the structure is simple and stable, but the transverse movement range is limited to only fine adjustment (about 100 mm)
Solution Approach 1:
The patent replaces the conventional mechanical sliding mechanism with a robotic arm system that uses motorized actuators and control systems to achieve precise transverse movement. The robotic arm includes a base, arm section, and hand section with multiple joints that can be controlled to move the operating table beyond the limited 100mm range to over 200mm while maintaining positioning precision through electronic control rather than mechanical constraints.
2Area of stationary object
If the table movement range is extended to allow greater transverse displacement, then more space is available for surgical staff, but the stability and precision of positioning may be compromised
Solution Approach 1:
The patent implements a dynamic positioning system where the robotic arm can adjust its arm section and hand section angles to achieve different transverse positions. The system includes sensors and control mechanisms that actively maintain positioning precision regardless of the table's transverse displacement, allowing the table to move 200mm or more while keeping the patient and surgical field properly positioned through real-time dynamic adjustment.
Solution Approach 2:
The robotic arm system incorporates feedback mechanisms including sensors that detect the position of the operating table and the arm configuration. This feedback is used by the control system to make real-time adjustments to maintain precise positioning of the surgical field relative to the imaging apparatus, ensuring that even when the table is moved 200mm transverse to create space for staff, the surgical area remains accurately positioned.
3Manufacturing precision
If the operating table is positioned close to the imaging apparatus for radiographic procedures, then imaging quality is improved, but there is insufficient space for surgical operations and staff movement
Solution Approach 1:
The patent enables dynamic repositioning of the operating table using the robotic arm system. The table can be moved transverse by 200mm or more to create adequate space for surgical staff and operations, while the robotic system maintains the alignment between the surgical field and imaging apparatus through coordinated movement of the arm sections and real-time positioning control, thus preserving imaging quality despite the increased distance.
4Adaptability or versatility
If the operating table allows large transverse movement, then flexibility in positioning is improved, but the mechanical structure becomes more complex and costly
Solution Approach 1:
The robotic arm system is designed to perform multiple functions: it can move the operating table transverse by 200mm or more to create space for staff, maintain precise positioning of the surgical field relative to the imaging apparatus, and provide stable support for the table. This multi-functionality justifies the increased complexity by delivering comprehensive positioning flexibility and adaptability that a simple sliding mechanism cannot provide.

AI summary
A patient placement table moving method may be used with a robotic operating table including a patient placement table, a base buried in or fixed to a floor and an articulated robotic arm including joints and having first and second ends. The first end may be supported on the base to be rotatable about an axis extending in a vertical direction. The second end may support the table. The method may include: horizontally arranging the table by the robotic arm at an imaging position for imaging with a medical imaging apparatus; and translating the table from the imaging position to a surgical operation position by the robotic arm. The surgical operation position may be away from the imaging position by 200 mm or more in a second direction orthogonal to a first direction in a horizontal plane, and the first direction is parallel with a longitudinal direction of the table.
