Small vascular bypass intra-operative auxiliary stoma forming device

Abstract

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.

Description

Technical field [0001] The invention relates to the technical field of vascular bypass surgery, in particular to an auxiliary anastomotic forming device in small vessel bypass surgery. Background technique [0002] Severe vascular stenosis or occlusion is the most common cause of ischemic disease in humans, which can lead to severe disability or even death, and bring a serious burden to society and families. Traditional medical technology using non-invasive sutures to perform end-to-side vascular anastomosis under a microscope is the most classic revascularization surgical technique. It is applied to coronary artery bypass, intracranial and extracranial vascular bypass, effectively reducing the risk of death and disability of patients. As the diameter of the blood vessel decreases, it is still difficult to visualize the anastomotic stoma even under a high-power microscope, which can easily lead to leaks or mis-seams on the opposite side of the vessel wall, leading to leakage or f...

AI Technical Summary

Problems solved by technology

Traditional medical technology uses non-invasive sutures to perform end-to-side anastomosis of blood vessels under a microscope. As the diameter of the blood vessel decreases, even under a high-power microscope, it is still difficult to directly visualize the anastomosis, which may easily lead to leakage or wrong seaming of the contralateral vessel wall, resulting in blood leakage or blockage at the anastomosis, and the difficulty of anastomotic techniques is multiplied , high requirements for the surgeon and prolonged operation time, which increases the risk of postoperative complications and greatly limits the general application of this technique
