青光眼激光滤过性手术监控系统的研制

Design of automatic feedback control system for laser filtering surgery

目的 :为避免在实施经外路非侵入式青光眼激光滤过术时 ,孔穿透后激光继续对周围特别是深部组织的伤害。方法 :提出采用面阵 CCD实时监视手术过程 ,并建立了孔切穿时色彩突变或亮度突变的识别反馈控制系统。结果 :通过面阵 CCD识别反馈控制系统达到了对二氧化碳激光器的控制。结论 :此系统有效地避免激光对组织的过照射。

Objective:To avoid damaging the deep tissue of eye around the laser hole on laser filtering surgery with iridotomy Methods: Using CCD camera to monitor surgical process and build a automatic feedback control system for judging the sudden change of color or brightness around laser hole Results: Control CO 2 laser by CCD camera automatic feedback control system Conclusion: The system can avoids effectively thermal demaga to the tissue by laser, and it has high clinical value
