Supporting Device for X-ray Terminal Positioning and Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user terminal systems in X-ray angiography systems suffer from decreased operability due to inefficient handling and support mechanisms, particularly when doctors need to perform touch operations on mobile terminals held by assistants, leading to inefficiencies and reduced usability.
Innovation Solution
A supporting device with a holder, supporter, and controller is introduced, where the supporter is movably connected to the holder and fixed at a predetermined position upon detecting an input operation, utilizing joints with solenoid actuators to stabilize the user terminal during operation, allowing for improved handling and reduced interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the user terminal is held by an assistant during surgery, then the terminal can be positioned near the patient, but the operability is decreased and mistaken input detection increases
Solution Approach 1:
The supporting device transitions from a static held position to a dynamic self-positioning system. The terminal is mounted on a movable supporting device with wheels that can autonomously move to the desired position near the patient, then lock in place. This eliminates the need for continuous human holding while maintaining precise positioning capability.
Solution Approach 2:
The supporting device provides self-service functionality by automatically positioning itself near the patient and stabilizing the terminal without requiring an assistant to manually hold it. The device includes self-locking mechanisms and automatic position adjustment capabilities that eliminate human intervention during the surgical procedure.
2Adaptability or versatility
If the supporter is made movable to allow repositioning, then the terminal can be relocated as needed, but the terminal becomes unstable during operation
Solution Approach 1:
The supporting device employs a dynamic stability system that transitions between movable and fixed states. During repositioning, the device moves freely on its wheels to the desired location. Once positioned, the supporter automatically locks or stabilizes to prevent movement during terminal operation, providing both repositioning capability and operational stability.
Solution Approach 2:
The supporting device operates in periodic cycles of movement and stabilization. It moves to the new position when repositioning is needed, then stabilizes for the duration of the surgical procedure. This periodic transition between mobile and stationary states allows the system to provide both adaptability and stability at different times in the operational cycle.
3Adaptability or versatility
If multiple displays are provided in examination room and operation room, then information can be accessed by multiple observers, but the system complexity increases
Solution Approach 1:
The user terminal serves multiple functions and multiple users through a single device. It can be accessed by doctors in the examination room, operators in the operation room, and other observers as needed. The terminal displays various types of information including surgical images, patient data, and control interfaces, eliminating the need for separate dedicated displays for each user or function.
Solution Approach 2:
Instead of providing multiple physical displays throughout the facility, the system uses a single user terminal that can be moved to different locations. The terminal copies or replicates the display functionality needed in both the examination room and operation room, providing the same information access capabilities without requiring duplicate hardware installations.

AI summary
A supporting device according to an embodiment includes a holder, a supporter, and a controller. The holder holds a user terminal that includes a detection surface that detects an input operation by an operator. The supporter is connected to the holder and is movably provided so as to locate a user terminal at a predetermined position, the user terminal being held by the holder. The controller fixes the supporter in a state where the supporter is located at a predetermined position when the detection surface detects the input operation.
