Surgical Frame Translating Lower Beam Linkage Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical frames with translating lower beams often face interference from moveable carts and surgical equipment during surgery, which can hinder the movement of the main beam or translating lower beam, necessitating a solution to prevent interference and enhance access and stability.
Innovation Solution
A surgical frame with a translating lower beam and a linkage system that allows the cart and surgical equipment to move independently, using a linear movement mechanism to reposition the linkage and cart relative to the translating beam, thereby avoiding interference with the main beam during rotations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surgical equipment is attached directly to the surgical frame or supported by moveable carts, then the equipment can be positioned and used during surgery, but the equipment may interfere with the movement of the main beam or translating lower beam
Solution Approach 1:
A linkage mechanism serves as an intermediary between the translating lower beam and the surgical equipment cart. The linkage includes a first arm connected to the translating lower beam and a second arm connected to the cart, allowing the cart to be moveably supported without directly interfering with the beam's movement. This intermediary structure enables both the beam to translate freely and the cart to support equipment while adapting to the beam's motion.
2Reliability
If the cart is fixed to the surgical frame, then the equipment is stable, but the cart cannot move independently to avoid interference with the main beam rotation
Solution Approach 1:
The cart is designed with dynamic support through the linkage mechanism, transitioning from a fixed connection to a moveable, adaptive connection. The linkage allows the cart to move independently in response to the translating lower beam's motion, providing both stability when needed and independence when the beam rotates or translates, thus resolving the contradiction between reliability and adaptability.
3Ease of operation
If the translating lower beam moves relative to the surgical frame, then access to the patient is improved, but surgical equipment may interfere with this movement
Solution Approach 1:
The movement of the translating lower beam and the surgical equipment cart are merged through the linkage mechanism. As the beam translates relative to the surgical frame, the linkage automatically coordinates the cart's movement, combining the motion of both components into a unified system. This reduces the complexity of manual coordination while maintaining improved patient access.

AI summary
A surgical frame and method for use thereof is provided. The surgical frame is capable of reconfiguration before, during, or after surgery using a moveable main beam supporting a patient thereon. The surgical frame includes a translating lower beam that is moveable between at least a first lateral position and a second lateral position, and a linkage and/or surgical equipment supportively and moveably attached to the translating lower beam or interconnected with the translating lower beam via the linkage. The linkage and/or the surgical equipment are moveable between a first position at or adjacent a first end of the translating lower beam and a second position at or adjacent a second end of the translating lower beam. The translating lower beam is used to join a first support portion and a second support portion of the surgical frame to one another, and movement of the translating lower beam affords access to a patient receiving area. A linear movement mechanism can be used to facilitate movement of the linkage and/or the surgical equipment along the translating lower beam to avoid interference with the main beam or the translating lower beam.
