Patient safety is a major issue in the field of healthcare. In relation to surgery, WHO published guidelines for safe surgery in 2009. Many perioperative practitioners have great concern about aspects of safety management of patients, such as operating on the wrong site or surgical count through good communication of the surgical team. In addition to those issues, the malfunction of surgical instruments has also led to serious medical accidents during surgery. Surgical instruments gradually wear out through a process of fatigue, fracture and erosive corrosion of metal. These are evidenced by microscopic striations in fatigue, microscopic corrosion pits or macroscopic discoloration in corrosion, and cracks in fracture. However, there is limited information about the frequency of defective surgical instruments or remnant pieces of broken instruments. We are not even aware how serious and harmful the subsequent medical accidents because of lack of the information on the history of breakag … More e in the individual surgical instrument. We do not have accurate information on the date of purchase and disposal of each instrument because we have to wash and sterilize a substantial amount of instruments all together. Those circumstances prompted us to establish a strategy to reduce the risk of medical accidents. To overcome these problems we invented novel automatic tracking system for the management of surgical instrument. The prototype of machine constructed of the image processing function to differentiate the type of surgical instrument such as scissors or forceps and the identification function of individual surgical instrument. A bar-coding or radio-frequency tagged system might be promising for the marking of individual instrument, but it would cost too much to introduce. Therefore, each surgical instrument was marked with minute color code. In order to differentiate the type of surgical instrument, the image processor was equipped with the computer-aided design data produced by the 3D scanner of each type of surgical instrument. The automatic identifier successfully recognized each surgical instrument marked with color code. The limitation number of the surgical instruments was observed for the identification of surgical instruments. There are several improvements to be needed to our machine. At present, we are able to identify only 6 types of surgical instrument because of limited capacity of memory. The speed to identify the individual surgical instrument is also to be improved. The larger the CAD of instrument becomes, the more time the machine spent to identify the instrument. Less

患者安全是医疗保健领域的一个重要问题。关于手术，世卫组织于2009年公布了安全手术准则。许多围手术期从业者非常关注患者安全管理的各个方面，例如在错误的部位上进行手术或通过手术团队的良好沟通进行手术计数。除了这些问题外，手术器械故障也导致手术期间发生严重医疗事故。手术器械的磨损是通过金属的疲劳、断裂和侵蚀腐蚀过程而逐渐发生的。疲劳中的微观条纹、腐蚀中的微观蚀坑或宏观变色以及断裂中的裂纹都证明了这一点。但是，关于手术器械缺陷或器械断裂残留碎片的频率信息有限。由于缺乏对破损历史的了解，我们甚至不知道随后发生的医疗事故的严重性和危害性。 ...更多信息 e在单个手术器械中。我们没有每件仪器的购买日期和处置日期的准确资料，因为我们必须一起清洗和消毒大量仪器。这些情况促使我们制定一项战略，以减少医疗事故的风险。为了克服这些问题，我们发明了一种新型的自动跟踪系统，用于手术器械的管理。该机器的原型构造了图像处理功能，以区分手术器械的类型，如剪刀或镊子，以及单个手术器械的识别功能。条形码或无线电频率标记系统可能有希望在个别文书上作标记，但采用费用太高。因此，每件手术器械均标有分钟色标。为了区分手术器械的类型，图像处理器配备了由每种手术器械的3D扫描仪产生的计算机辅助设计数据。自动识别器成功识别了标有颜色代码的每件手术器械。观察手术器械的数量限制，以识别手术器械。我们的机器有几处需要改进。目前，由于记忆容量的限制，我们只能识别6种手术器械。识别单个手术器械的速度也有待提高。仪器CAD的规模越大，机器识别仪器的时间就越长。少
