日本古川电气公司在1985年5月宣布,该公司与东京女子大学协作,成功地研制了直径非常小的纤维血管内窥镜。世界上第一台血管内窥镜是由约6000根导象纤维包裹一根导激光纤维组成的。这种内窥镜与常用的使用纤维内窥镜与激光纤维两部分装置的激光治疗系统完全不同。它可以把激光非常精确地照射到目标区,而不会损伤邻近的正常细胞。另外,由于终端物镜 Japan’s Furukawa Electric announced in May 1985 that the company, in collaboration with Tokyo Women’s University, successfully developed a very small diameter fiberoptic endoscope. The world’s first vascular endoscope consists of about 6,000 guided fibers wrapped around a laser fiber. This endoscope and the commonly used fiber endoscopy and laser fiber two-part laser treatment system is completely different. It shines the laser very precisely onto the target area without damaging neighboring normal cells. In addition, due to the terminal objective
