C-arm X-ray Base Rotary Disc Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
C-arm X-ray imaging apparatuses face challenges in maintaining an appropriate distance between the patient and the X-ray bulb tube when the patient bed is low, and in preventing collisions between the bulb tube and the patient bed during the rotation of the C-shaped bracket.
Innovation Solution
A base with a drive member, horizontal portion, and sunk portion, featuring a rotary disc that can rotate to adjust the position of the C-shaped bracket, maintaining a safe distance from the patient and preventing collisions by allowing the bulb tube to be positioned lower without affecting the rotation of the C-shaped bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the patient bed is lowered to adapt to doctor's gesture, then the ease of operation is improved, but the patient is exposed to larger X-ray radiation dose and the bulb tube may collide with the patient bed
Solution Approach 1:
The patent introduces a vertical dimension adjustment by lowering the base platform, which allows the C-shaped bracket to be positioned lower without raising the bulb tube relative to the patient. This dimensional change enables the bed to be lowered for operator comfort while maintaining safe distance between the bulb tube and patient, thus reducing X-ray radiation exposure.
2Ease of operation
If the patient bed is lowered, then the ease of operation is improved, but the bulb tube is likely to collide with the patient bed during rotation
Solution Approach 1:
By lowering the base platform, the patent creates additional vertical clearance between the bulb tube and the patient bed. This allows the C-shaped bracket to rotate through a larger angle range without the bulb tube colliding with the bed, thereby improving reliability while maintaining ease of operation.
Solution Approach 2:
The patent preemptively lowers the base platform to prevent potential collisions between the bulb tube and patient bed during rotation. This preliminary structural adjustment ensures that even when the bed is lowered for operator comfort, there is sufficient clearance to avoid collisions, thus maintaining reliability.
3Adaptability or versatility
If the C-shaped bracket is rotated to facilitate imaging from different angles, then the adaptability is improved, but the bulb tube may collide with the patient bed
Solution Approach 1:
The patent uses vertical dimension adjustment by lowering the base platform to increase the rotation angle range of the C-shaped bracket. This allows imaging from different angles (improving adaptability) while maintaining sufficient clearance to prevent bulb tube collision with the patient bed (maintaining reliability).

AI summary
Provided are a C-arm X-ray imaging apparatus and a base for the apparatus, the base comprising a drive member, a horizontal portion and a sunk portion. The sunk portion comprises a rotary disc connected to the horizontal portion and the drive member, and an upper surface of the rotary disc is flush with or lower than a lower surface of the horizontal portion. The rotary disc is configured to be rotatable about its center of rotation under the driving of the drive member so as to drive the base to rotate.
