Description

A coronary anastomosis path simulation device for coronary artery bypass surgery

technical field

The utility model relates to the technical field of coronary artery bypass surgery, in particular to a vascular anastomosis path simulation device for coronary artery bypass surgery.

Background technique

Coronary artery bypass surgery has become one of the main treatment methods for patients with severe coronary heart disease. During the operation, it is often necessary to use the great saphenous vein or radial artery as a bridge material to anastomose with the diseased target vessel. Since the length of the bridge material required is unknown, it is generally necessary to take Longer blood vessels meet the needs of surgery, which undoubtedly increases the trauma of the incision, and also causes unnecessary damage and waste to the own blood vessels. When bypassing, the proximal end of the bridge material is anastomosed on the aorta, and one or more anastomotic stomas at the distal end are connected to the aorta. Side-to-side or end-to-side anastomosis, the anastomosis operation, especially the sequential anastomosis operation with multiple anastomotic ports, requires the operator to adopt the appropriate length and anastomosis angle of the graft vessel to achieve the maximum blood flow, and at the same time, the graft vessel will not be too large. Shortness causes stretching and narrowing of blood vessels and even tears the anastomotic stoma, or vascular kinking affects blood flow due to too long graft vessels. What is more difficult is that volume adjustment and blood pressure control are required during the bypass process, especially cardiopulmonary bypass. With descending coronary artery bypass grafting, there will be a significant difference between the size of the heart and the actual size of the heart. Traditional surgical operations are generally adjusted based on the experience of the operator, which lacks precision. Once a problem occurs after the anastomosis, it is difficult to perform the anastomosis operation again, which affects the long-term effect of the patient. The rate of vascular patency in the long-term, and even perioperative death, if the length of the indwelling graft vessel cannot be estimated on the normal heart, the final surgical effect will be difficult to achieve homogeneity and optimization.

Therefore, in view of the above problems, a vascular anastomosis path simulation device for coronary artery bypass grafting is proposed.
