DEVELOPMENT OF ROBOTIC ENDOSURGERY AND ITS CLINICAL APPLICATION

(1)我们开发了一种指尖视图控制系统和多功能腹腔镜探头，并成功应用于多种临床情况。我们还完成了几个内窥镜手术模拟视频，用于医学生和年轻医生的教育。(2)指尖视图控制系统是一种用于腹腔镜手术的机器人内窥镜视图控制系统。视场由钳子手柄上的控制开关移动，可以实现8个不同的方向，放大和缩小，并恢复默认设置。由于瞄准镜本身实际上并不移动（CCD会移动），因此瞄准镜支架也不会移动，因此不存在移动支架臂导致事故的风险。该系统不仅节省了手术台周围的空间，还可以防止支架臂挡在外科医生的路上，并防止范围干扰腔内的镊子。(3)多功能腹腔镜探头具有灌洗、抽吸、电灼3种不同功能。使用该探针，缩短了手术时间，避免了频繁插拔探针带来的并发症。因为这个探针是可重复使用的，另一个优点是它的成本效益，因为这个探针是可重复使用的。(4)我们的项目也有一些未来的前景，低成本的远程手术系统，目前仍在奥林巴斯公司的开发中，通过指尖视图控制系统，利用电信设备（ISDN，互联网等）进行远程手术可能很快就会实现。

(1) We have developed a finger tip view control system and multifunctional laparoscopic probe, and successfully adopted it in several clinical situations. We have also completed several endoscopic surgical simulation videos for the education of medical students and young doctors.(2) The finger tip view control system is a robotic endoscopic view control system used during laparoscopic surgery. The field of view is moved by a control switch on the handle of the forceps, making it possible for eight different directions, in and out zooming, and restoration of the default settings. Since the scope itself doesn't actually move (the CCD does), the scope holder doesn't move either, so there is no risk of an accident caused by moving the holder arm. This system not only saves space around the operating table, it keeps the holder arm from getting in the surgeon's way and prevents the scope from interfering with the forceps inside the cavity.(3) The multifunctional laparoscopic probe has 3 different functions : irrigation, suction, and electrocautery. By using this probe, operating time was shorter and complications caused by the frequent inserting and extracting of probes was avoided. Because this probe is reusable, another advantage was its cost effectiveness, as this probe is reusable.(4) Our project also has some future prospects for a low cost telesurgery system which is still undergoing development by Olympus Co. By using the finger tip view control system, telesurgery using telecommunications equipment (ISDN, Internet etc.) may soon be achievable.
