LED光源手术无影灯的研制

摘要

目的:研制一款新型光源手术用无影灯,以解决传统式手术无影灯存在的弊端.方法:选用发光二极管(LED)作为光源灯,经过多次验证,选择合适的灯珠数量及色温,调节供电电压,进行光学曲线的配置以及驱动电路的优化.结果:实际使用验证,在手术中能清楚地分辨器官组织和血管,清晰地观察处于切口和体腔中不同深度、大小及对比度低的组织.结论:经过相关机构的检测和临床试验,LED光源手术无影灯能够满足手术需求,适合手术照明使用.%Objective: To develop a new operating astral lamp by using LED, a kind of new light source, so as to resolve the existed problems in traditional light source Methods:The LED was used as the light source, and the appropriate lamp bead amount and proper color temperature were chosen through the experiment of repeated verification. And the configuration of optical curve and optimization of drive circuit were exerted through adjusted the service voltage. Results: As the verification of practice results, the tissue and vessel could be clearly identified during operation. And the tissues of different depth, size and lower contrast in the notch and coelom could be observed at the best level during operation. Conclusion: Through the test and clinical experiment of related organization, the astral lamp of LED can completely satisfy the demand of operation and suit for the usage of illumination in operation.
