Abstract

This paper is the continuation of the Phase I report published in 1992 by Canestri. It contains recent findings on how to speed-up the process of sublimated volume forecasting for a TEM11* CO2 laserbeam in CW mode following an original model proposed by the author--called LCA--here presented in a simplified version (LCA-s) on PMMA (polymethylmethacrilate) samples. Other interesting parameters, such as the time required to create the minimal injury vb along with its physical interpretations, are reported and explained. TEM11*, TEM01* and TEM00 beams profiles are also compared and discussed for LCA-s. The results of both Phase I and Phase II of this investigation can be integrated in one single solution package for the end-user, combining fast decisions making and operational features. The final part of this paper describes the 'helmet-mounted' data recall visor methodology which allows the surgeon to access to a data base for information retrieval during the course of an operation without interrupting the surgical case itself. This particularly interesting application allows the surgeon to consult a centrally-located data base which contains important information regarding similar clinical cases, choice of laserbeam profiles and focal lengths, simulation of beam behaviours, performances and other data. The on-line and direct access to the data base supports him in all those borderline situations in the O.R. in which the laser device type and configuration/calibration play a device role in the success of the operation. Also, the helmet-mounted display frees surgeon's hands in order to allow him to continue the operation while consulting the data base on-line, thus speeding up decision processes regarding changes of laser set-up, general calibration optimization and remote clinical consultancy.

骨科手术中连续波CO2激光在线控制计算机算法的提出。第二阶段:简化算法版本(LCA-s)和头盔式数据访问设备解决方案。
本文是Canestri于1992年发表的第一阶段报告的延续。它包含了关于如何加快TEM11* CO2激光在CW模式下升华体积预测过程的最新发现,该过程遵循作者提出的原始模型-称为LCA-在PMMA(聚甲基丙烯酸甲酯)样品上以简化版本(LCA-s)呈现。其他有趣的参数,如创建最小伤害vb所需的时间,以及它的物理解释,报告和解释。并对LCA-s的TEM11*、TEM01*和TEM00光束剖面进行了比较和讨论。该研究的第一阶段和第二阶段的结果可以集成到一个解决方案包中,为最终用户提供快速决策和操作功能。本文的最后一部分描述了“头盔式”数据召回遮阳板方法,该方法允许外科医生在手术过程中访问数据库进行信息检索,而不会中断手术病例本身。这个特别有趣的应用程序允许外科医生查阅中央数据库,其中包含有关类似临床病例的重要信息,激光束轮廓和焦距的选择,光束行为的模拟,性能和其他数据。在线和直接访问数据库支持他在手术室的所有边缘情况下,激光设备类型和配置/校准在手术成功中发挥设备作用。此外,头戴式显示器解放了外科医生的双手,使他能够在在线咨询数据库的同时继续手术,从而加快了关于激光设置更改、一般校准优化和远程临床咨询的决策过程。
