Motorized Surgical Table Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient positioning systems for surgery, particularly in prone positions, are prone to manual errors that can dislodge monitoring equipment and pose risks due to abrupt movements, and existing devices lack efficient and safe mechanisms for adjusting patient alignment and support during spinal and orthopedic procedures.
Innovation Solution
A motorized surgical table system with vertical-lift columns, lateral-tilt assembly, and modular patient support configurations that allow for precise positioning, including Trendelenburg, reverse Trendelenburg, and cantilevered support, enabling safe and efficient adjustment of the patient's position through motorized control and user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning methods are used, then the patient can be positioned on the operating table, but monitoring equipment may be dislodged and patient safety is compromised
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated motorized positioning system. The motorized table and positioning mechanisms eliminate the need for staff to manually manipulate the patient, thereby preventing dislodgment of monitoring equipment while ensuring precise and safe patient positioning throughout the surgical procedure.
Solution Approach 2:
The positioning system is designed to automatically position and maintain patient alignment without requiring continuous manual intervention. The motorized mechanisms self-adjust to predetermined positions and maintain stability, reducing the risk of accidental movement or equipment dislodgment during surgery.
2Stability of the object's composition
If passive frames like Wilson Frame are used for support, then patient alignment may be improved, but the device complexity increases and manual manipulation remains difficult
Solution Approach 1:
The motorized surgical table integrates multiple positioning functions into a single unified system. It can perform alignment, elevation, lateral tilting, and positioning adjustments all through one automated platform, eliminating the need for separate passive frames and manual manipulation devices, thereby reducing overall device complexity while maintaining alignment stability.
Solution Approach 2:
The system transitions from static passive frames to dynamic motorized positioning. The table can actively adjust and maintain patient alignment in real-time, adapting to different surgical requirements and patient anatomies without requiring complex manual manipulation or multiple separate devices.
3Adaptability or versatility
If T-pin mechanisms are used for table positioning, then patient positioning during surgery is enabled, but operator error can cause unexpected tilting and catastrophic injury
Solution Approach 1:
The patent replaces the manual T-pin mechanism with an automated motorized positioning system. The motorized table responds to controlled input signals rather than manual pin manipulation, eliminating the risk of inadvertent tilting due to operator error. The system maintains patient positioning adaptability while significantly reducing the harmful factor of unexpected movement that could cause catastrophic injury.

AI summary
A surgical table including a central bottom portion is provided. The surgical table includes at least one first wheel adjacent a first end of the table, at least one second wheel adjacent a second end of the table, and a first stabilizing bar connected to the first wheel and the second wheel. The stabilizing bar is movably connected to the central bottom portion. The stabilizing bar is configured for coordinated movement of the wheels.
