Surgical Table–Light Coordination for Stable Site Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical lighting systems fail to adequately adjust illumination in response to changes in the position and posture of a surgical table, leading to hindered surgical interventions.
Innovation Solution
A system comprising a surgical table controller and a surgical light controller that exchange data to coordinate the behavior of the surgical table and light, allowing adjustments in illumination based on table actuations, including changes in position, height, and posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the surgical table is repositioned to change patient posture, then the surgical accessibility is improved, but the illumination quality at the surgical site deteriorates
Solution Approach 1:
The surgical light controller receives position feedback from the surgical table controller about tabletop movements, and automatically adjusts light position and intensity in response to maintain optimal illumination at the surgical site
Solution Approach 2:
The surgical table and surgical light are merged into an integrated system through communication interfaces, allowing coordinated control where table repositioning automatically triggers corresponding light adjustments without separate manual intervention
2Illumination intensity
If the surgical light position is adjusted to follow the surgical site, then the illumination quality is improved, but the system complexity increases
Solution Approach 1:
The surgical table controller acts as an intermediary that mediates between the surgical table actuators and the surgical light controller, transmitting position signals that enable automatic light tracking without requiring direct complex coupling between all system components
3Illumination intensity
If manual adjustment of surgical light is performed after table repositioning, then the illumination can be optimized, but the time required for surgical intervention increases
Solution Approach 1:
The surgical light controller proactively adjusts illumination parameters in advance based on predicted surgical site position from table actuator signals, eliminating the need for delayed manual adjustment and maintaining optimal illumination throughout the repositioning process
