In order to make it possible to anastomose Micro Vessels (diameter < 0.5mm), and to expect the big stride in the field of microsurgery, three projects as below have been carried out.a) The Micro Stereo Video System which consists of a stereo video system and an operative microscope has been developed by the head investigator of this research. Under this system, the anastomosis of micro vessels (diameter 1.0- 1.3 mm) has been challenged and 75% success ratio has been gained. But several problems, for example, darkness of vision and noise of goaggles have been clarified.b) Micro forceps, scissor, cramp and the special needle which is made by metal coating on one stump of 10-0 nylon for ULTRA-MICROSURGERY have been created. It was meenigful to use such instruments and needle with thread for anastomosis of Micro Vessels (diameter < 0.5mm).c) Usage of a low-output CO_2 laser for Micro Vessel anastomosis.The damage of vessels by CO_2 laser energy has been investigated. And by using a low output CO_2 Laser, the micro vascular anastomosis of Albiro rats have been carried out and it was revealed that operative time was shortened and that patency ratio after anastomosis increased compared with conventional method.

为了使微血管(直径0.5 mm)吻合成为可能，并期待在显微外科领域取得更大的进步，本研究开展了以下三个项目：a)由立体视频系统和手术显微镜组成的显微立体视频系统。在该系统下，对直径1.0~1.3 mm的微血管进行了吻合术，成功率达75%。B)微型钳子、剪刀、抽筋，以及在一根10-0尼龙的残端上涂覆金属制成的特殊针头，用于超显微手术。用这种器械和螺纹针吻合直径0.5 mm的微血管是一种很好的方法。c)使用低输出CO_2激光进行微血管吻合。用小功率CO_2激光对大白鼠进行微血管吻合，结果表明，与常规方法相比，手术时间缩短，吻合口通畅率提高。
