智能白内障超声乳化技术中针头对碎片的实时跟踪技术

Phacoemulsification Probe Real-Time Tracking for Cataract Fragments of Intelligent Cataract Phacoemulsification

本文提出一种超声乳化针头对白内障碎片的实时跟踪技术,该技术可逐步实现将智能控制贯穿于整个白内障手术操作流程.智能超声乳化技术的关键因素在于:识别白内障和正常组织,识别白内障的颜色和硬度;实时跟踪乳化针头附近区域的白内障片段;根据实时结果自动控制乳化针头正确释放能量,避免损伤眼球.霍夫变换、k最近邻分类器和智能控制技术是本文提出的新超声乳化探针实时跟踪白内障片段方法的基础.实验结果分析表明,本新方法实现了超声乳化手术的智能化控制,并大幅提高了手术的安全性和效率.

This report introduces the technique of phaco-emulsification probe real-time tracking for cataract fragments which can eventually realize the using of intelligent control throughout the procedure of cataract operation .The key factors of smart phaco-emulsification techniques are ：recognition of cataract and normal tissue ;recognition of the color and hardness of cataract ;real-time tracking of cataract fragments in the area near emulsifying probe ;automatic control of the emulsion probe which could accord to the real-time results to release energy and avoid eye injury caused by over-released energy .The basic to this new method of phaco-emulsification probe real-time tracking for cataract fragments are Hough transform ,k-nearest neighbor classifier and intelligent con-trol technology .By analyzing the experiment results ,this new method realizes the intelligent control of phaco-emulsification opera-tion and improves the operation’s safety and efficiency considerably .
