This technology is a 3D-printed partial occlusion device that facilitates microvascular anastomosis repair with improved visibility, stability, and safety.
End-to-end anastomosis involves the stitching of two vessels together during microsurgery. Gaps in the anastomosis may cause leakage, which can be a life-threatening surgical complication. During the repair of the anastomosis, oozing blood from the leakage can obstruct the surgeon’s field of view. Currently, a cotton-tip applicator may be used to control the blood flow at the leakage site by occlusion; however, the shedding of cotton fibers into the wound can lead to potential infections, and these tools also have size and shape limitations.
This technology is a 3D-printed partial occlusion device designed to facilitate the repair of microvascular anastomoses in microsurgery. The device is designed with a flat bottom and a curved front and top, designed to enhance stability during surgical procedures. The device is placed under the suturing site, and its position can be adjusted based on the level of leakage so that the vessel sits on the device at different elevations, achieving occlusion of blood flow. The occlusion creates a blood-free environment, enabling the surgeon to repair the leakage site without oozing blood obstructing the field of view. The device is 3D-printed using a biocompatible resin, which eliminates safety risks associated with material shedding and enables customization for various surgical scenarios.
