A surgical tool called the "Artery Clamp.4-1.0mm Pair" was created especially to work with tiny arteries that have sizes between 0.4 and 1.0 mm. These clamps are commonly utilized in cardiac, vascular, and microsurgical procedures where sensitive control and accuracy over tiny blood arteries are essential. During a variety of surgical procedures, the surgeon can use these clamps to approximation (pull the edges together) or occlude (temporarily block) tiny arteries.
