The invention provides a small vascular bypass intra-operative auxiliary
stoma forming device. The traditional medical technologies for carrying out vascular end-to-side
anastomosis by the aid of noninvasive sutures under microscopes are the most classic
revascularization surgical technologies, but stomas are difficult to directly visualize along with diminishing of the diameters of blood vesselseven under the high-power microscopes, and the problems of
vulnerability to missing suturing or mistaken suturing of vascular walls on opposite sides, blood leakage or blockage of stomas, multiplyingof difficulty of
anastomosis technologies and great restriction on universal application of the
anastomosis technologies can occur. The vascular bypass intra-operative auxiliary
stoma forming device has the advantages that the vascular bypass intra-operative auxiliary
stoma forming device is applied to small vascular bypass, two
layers of vascular walls of blood vessels of a
receptor can be separated from each other on the premise that damage on inner membranes of the blood vessels is not increased, the intra-operative microscopic
visualization degrees can be upgraded, the purposes of optimizing suture programs, increasing the anastomosis speeds and shortening the
operation time can be achieved, accordingly, the operating difficulty can be lowered, and the
postoperative complication incidence rate can be reduced.
