Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing operating tables have limited horizontal movement range and poor freedom of movement, making it difficult for medical personnel to position patients correctly and maintain sufficient space during surgeries, which hinders smooth surgical procedures.
Innovation Solution
A robotic operating table equipped with a multi-jointed robotic arm and an operation device that allows for setting and changing the rotation center position, enabling large-range movement and rotation of the table in yaw, pitch, and roll modes, facilitated by a user-friendly interface with move direction receivers and a display for intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating table uses a fixed base with limited horizontal movement, then the structure is simple and stable, but the range of movement of the table is small and freedom of movement is poor
Solution Approach 1:
The patent replaces the traditional mechanical sliding mechanism with a robotic arm system that uses motors and controllers to move the table. This substitution enables complex movements including horizontal translation, vertical lifting, and rotation about multiple axes, dramatically increasing the range and freedom of movement while maintaining structural stability through controlled actuation
Solution Approach 2:
The patent transforms the static fixed-base structure into a dynamic system where the robotic arm can adjust the table's position and orientation in real-time. The table can be moved to various positions (patient receiving, anesthetization, surgical operation, imaging) and rotated about vertical and horizontal axes passing through different points on the table, providing adaptability for different surgical scenarios
2Ease of operation
If the table has limited horizontal movement range, then the device structure remains simple, but it is difficult to move the table to various desired positions and leave sufficient space for medical personnel
Solution Approach 1:
The robotic arm system replaces limited mechanical sliding with motorized actuation capable of moving the table to multiple predetermined positions (patient receiving, anesthetization, surgical operation, imaging) and any intermediate position within the workspace, enabling precise positioning while maintaining clear space for medical personnel to move around the patient
3Adaptability or versatility
If the rotation center position is fixed, then the control system is simple, but the freedom of rotation is limited for different surgical positions
Solution Approach 1:
The robotic arm system provides universal rotation capability about multiple axes (vertical axis and horizontal axes) passing through different points on the table. This multi-functional rotation system allows the table to be oriented in various directions depending on surgical requirements, whether rotating about the center or about edges, without requiring separate mechanisms for each rotation mode
Solution Approach 2:
The system dynamically changes the rotation parameters by adjusting the position of the rotation axis based on the selected operation mode. The controller modifies the rotational movement parameters to rotate the table about different axes and through different angles, adapting to various surgical positioning requirements

AI summary
A robotic operating table may include: a table on which to place a patient; and a robotic arm including a plurality of joints, and having a first end supported on a base fixed to a floor, and a second end supporting the table; and an operation device including: a mode-set operation receiving unit that receives a set operation to set a rotation mode for rotating the table; a move operation receiving unit that receives a move operation to move the table; and a display. When the mode-set operation receiving unit receives the set operation to set the rotation mode, the display may display setting information for setting a rotation center position of the table. When the move operation receiving unit receives the move operation in a state where the rotation center position is set, the robotic arm may rotate the table about a rotation axis at the rotation center position.
