Operating Room Lighthead Projection Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting adjustment methods in environments like operating rooms and precision industries are inconvenient and hazardous as they require operators to divert their attention from the task at hand to adjust lighting features, disrupting the procedure and risking incorrect adjustments due to head shadows and the need to alternate focus between adjustment and the surgical site.
Innovation Solution
A lighting apparatus with a user interface that projects adjustment instructions around the light field using a laser light source and a light-transmitting optical film with diffractive and/or refractive microstructures, allowing operators to adjust lighting features without looking away from the surgical site by providing clear, readable instructions within the light field's vicinity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional adjustment elements with graphic symbols are used, then the lighting can be adjusted, but the operator must divert attention from the surgical site to the adjustment elements and instructions
Solution Approach 1:
A camera captures the surgical site and displays it on a monitor positioned near the adjustment elements. The monitor serves as an intermediary, allowing the operator to view the surgical site while adjusting lighting, thereby eliminating the need to divert attention between multiple locations and preventing procedure interruption.
2Measurement precision
If the operator focuses on the adjustment elements, then precise lighting control is possible, but the operator cannot observe the surgical site simultaneously
Solution Approach 1:
The camera and monitor system acts as an intermediary that reproduces the surgical site visual information at the adjustment element location. This allows the operator to maintain precise focus on lighting controls while simultaneously observing the surgical site through the monitor, ensuring both adjustment precision and continuous surgical site monitoring.
Solution Approach 2:
The camera creates a visual copy of the surgical site and displays it on the monitor. This copy enables the operator to observe the surgical site conditions while adjusting lighting parameters, maintaining both precise control and continuous monitoring without dividing attention.
3Ease of operation
If adjustment instructions are provided via graphic symbols, then operation guidance is available, but the instructions may not be clearly visible or readable during surgery
Solution Approach 1:
The system merges the surgical site video feed with the adjustment instructions on the same monitor display. This combination ensures that both the surgical site view and the adjustment guidance are clearly visible simultaneously, eliminating visibility issues associated with separate graphic symbols and providing comprehensive information without loss.
4Ease of operation
If the operator alternates focus between adjustment elements and surgical site, then both adjustment and observation are possible, but the procedure efficiency decreases
Solution Approach 1:
The monitor serves as an intermediary that brings the surgical site view to the adjustment element location. This eliminates the need for alternating focus between separate locations, allowing the operator to perform both adjustment and observation simultaneously at one position, thereby maintaining procedure efficiency while achieving dual functionality.
