Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shadowless operating lamps in clinical settings face issues with mechanical flexibility, contamination risk during adjustment, inability to precisely control brightness, and inadequate adjustment for small fields of vision due to complex structures and mechanical connections.
Innovation Solution
An automatically adjustable shadowless operating lamp with a telescopic support rod, rotatably connected lighting assemblies, and an intraoperative adjuster that uses infrared sensors and hydraulic pumps to adjust position, angle, and brightness, allowing for hands-free operation and reduced contamination risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical adjustment mechanisms are used in shadowless lamps, then the lamp can be adjusted to different positions and angles, but the flexibility of joints decreases after long time use and the structure becomes complex
Solution Approach 1:
The patent replaces the traditional mechanical adjustment mechanism with an infrared remote control system. The shadowless lamp includes an infrared receiving tube that receives infrared signals from a remote controller, which then controls the lamp's position and brightness through electronic actuation rather than manual mechanical adjustment. This eliminates complex mechanical joints and their associated flexibility degradation over time.
2Ease of operation
If manual adjustment of the operating lamp is performed, then the lamp position can be changed, but the hand leaves the sterile area increasing contamination risk
Solution Approach 1:
The patent introduces an infrared remote controller as an intermediary device that allows the surgeon to adjust the shadowless lamp without leaving the sterile field. The surgeon can manipulate the remote controller while maintaining hand sterility, and the infrared signal transmits the adjustment commands wirelessly to the lamp's receiving tube, eliminating direct contact between the hand and the lamp adjustment mechanisms.
3Adaptability or versatility
If fixed brightness operating lamps are used, then the structure is simple, but the doctor can't control the brightness according to operation situation
Solution Approach 1:
The patent implements dynamic brightness control by equipping the shadowless lamp with a brightness adjusting tube that responds to infrared signals from the remote controller. The brightness can be dynamically adjusted during surgery according to the operational needs, transitioning from a static fixed-brightness design to a dynamic adjustable system that adapts to different surgical conditions without requiring complex manual intervention.
4Ease of operation
If ceiling-mounted shadowless lamps are used, then the installation is straightforward, but the lamp cannot be precisely adjusted for small fields of vision
Solution Approach 1:
The patent replaces the traditional ceiling-mounted mechanical adjustment system with an infrared-controlled positioning system. The shadowless lamp can be precisely positioned for small fields of vision through infrared signal commands that control the lamp's movement and orientation, achieving high positioning precision without relying on complex mechanical adjustment mechanisms that degrade over time.
