Surgery Procedure Recorder and Objective Analysis System

用于腹腔镜手术的手术记录仪已被提出并研制成功。目的是对微创手术的客观分析，或手术事故的术后调查。研制了一种带有力/位置传感装置的数据钳，并利用活体猪成功地对该系统进行了实验验证。对于日本小型手术室的临床应用，需要紧凑的系统组织。因此，我试图通过进行人体针灸的非侵入性数据采集来优化数据采集系统，而不是使用健康的猪进行常规的外科实验。设计了一种新型传感器单元，它由称重传感器、磁性位置传感器和传感器外壳组成，用于将传感器聚集在针灸医生的手指周围。利用美国国家仪器公司的Lab-View软件开发了紧凑型数据处理系统，用于力/位置数据的采集、显示和灵活的数据分析。然后在资深针灸医生的支持下进行初步实验，该系统可以很容易地用于腹腔镜手术。此外，这些实验还得出了一个有趣的结果，即物理方面的预防医学基础研究。

Surgery Recorder for laparoscopic surgery have been proposed and developed. The aim was the objective analysis of low-invasive surgery, or the post-operative investigation of surgical accidents. A data forceps with force/position sensing devices has been developed, and the experimental verification of the system was successfully done by using living pig so far. For clinical use of the system in Japanese small operating rooms, the compact system organization was needed. I therefore tried to optimize the data acquisition system by carrying out the non-invasive data acquisition of human acupuncture, instead of conventional surgical experiments by using healthy pigs. A new sensor unit was designed, which consisted of a load cell, a magnetic position sensor, and a sensor housing to gather sensors around a finger of an acupuncturist. The compact data handling system with Lab-View software by National Instruments Corp. was also developed for the force/position data acquisition, presentations and the flexible data analyses. The preliminary experiments were then held with the support of a senior acupuncturist, that system could be easily utilized for the laparoscopic surgery. Moreover, these experiments also came to an inter-esting result of the fundamental study on preventive medicine of physical aspects.
