Vein holder for coronary bypass surgery.

Area of Science:

• Cardiovascular Surgery
• Biomedical Engineering

Background:

• Coronary bypass surgery requires precise anastomosis of vein grafts.
• Current methods using vascular forceps can cause crush injuries to delicate vein grafts.

Purpose of the Study:

• To design and evaluate novel vein holders for coronary bypass surgery.
• To improve the safety and efficiency of vein graft anastomosis.

Main Methods:

• Development of two types of vein holders: one for vein graft-to-coronary artery anastomosis and another for vein graft-to-aorta anastomosis.
• Utilizing the holders to maintain a three-dimensional position of the vein graft during suturing.

Main Results:

• The vein holders eliminate the need for forceps, preventing crush injuries to the vein graft wall.
• One design facilitates side-to-side anastomosis in sequential grafting.
• The other design enables single-surgeon anastomosis for vein graft-to-aorta procedures.

Conclusions:

• The developed vein holders offer a significant advantage in coronary bypass surgery.
• These devices enhance graft protection and surgical efficiency during anastomosis.
