A suture-retaining spring device to assist in microvascular procedures

Abstract

Microvascular anastomosis needs a skilled assistant. A simple spring device subtracts this need. This device is an “add-on” to the conventional vascular clamp. It helps the surgeon to perform the anastomosis alone by lifting up the anterior wall away from the posterior wall. It allows hitching of the sutures throughout the circumference of the vessel, which is not possible with an Acland clamp (can only hitch sutures at 180°). This also helps in the accurate placement of sutures and allows clear vision of the lumen without compromising vision or working space.
