Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical lighting systems obstruct the airspace above the surgical field, limiting visibility and ergonomics for surgical teams, and are not adaptable to the specific lighting needs of minimal invasive surgeries, which may require conversion to open surgery.
Innovation Solution
A surgical light system using LEDs with a controller to adjust brightness across divided sections of the surgical light field, integrated into the ceiling to maintain a clear airspace, and equipped with sensors for dynamic illumination adjustments based on object position and brightness, allowing for customizable and shadow-free lighting without the need for direct operation of light heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional surgical lights are suspended above the surgical field to provide sufficient illumination, then the surgical site can be adequately illuminated, but the airspace above the surgical field is obstructed, limiting visibility and ergonomics
Solution Approach 1:
The patent transitions from vertical suspension (above the surgical field) to horizontal integration (in the ceiling), moving the light sources to a different spatial dimension. This allows the lights to be embedded in the ceiling structure rather than hanging in the airspace, providing illumination without obstructing the surgical team's view and movement.
Solution Approach 2:
The surgical light field is divided into multiple sections, each covered by specific light sources. The ceiling is segmented into different zones with light sources integrated into specific ceiling sections. This segmentation allows selective illumination of different surgical areas while maintaining clear airspace in other regions.
2Illumination intensity
If traditional surgical lights are used to ensure sufficient illumination for open surgery, then optimal surgical site illumination is achieved, but the system cannot be placed outside the airspace above the surgical field
Solution Approach 1:
The surgical lighting system is designed to be universally applicable by integrating light sources into the ceiling structure, which can serve multiple functions: providing illumination, maintaining clear airspace, and allowing flexible positioning. The system can illuminate different surgical sites by activating different ceiling-integrated light sources as needed.
3Adaptability or versatility
If multiple light sources are used to cover different sections of the surgical field, then specific brightness can be adjusted for each section, but the system complexity increases
Solution Approach 1:
Different sections of the surgical field receive different brightness levels according to their specific illumination needs. The controller enables independent brightness adjustment for each light source or group of light sources, allowing critical areas to be brighter while peripheral areas receive sufficient but lower illumination, optimizing both adaptability and energy efficiency.
