A number of shortcomings have been found with manual vessel suture. They are arising mainly from these facts: Thrombosis is not infrequent at the anastomotic portion, owing to the irregularity and injury of intima at the anastomotic line; the method requires too much time; it is difficult to anastomose small-calibered vessels.
The present paper deals with a new vessel-suture apparatus which is made to overcome these shortcomings of the manual method and to make the complicated vessel suture easy and accessible even for unspecialized surgeons. So far, the only paper on the mechanized vessel suture seems to be that of Androsov,1 of the Soviet Union, of which I happened to learn in the course of my experimentation on this apparatus. The new apparatus is devised by my own idea, supported by my experimental evidence that if mechanical anastomosis is achieved with the vessel ends securely everted, injury of the
