A specialist surgical tool called the "Approximator Clamp Frame 1.0-2.25mm" is made to work with tiny arteries and vessels that have sizes between 1.0 and 2.25 mm. The main purpose of this kind of clamp is to approach (bring the edges together) the vessels or arteries during operations like anastomosis, grafting, or repair in vascular, microsurgical, and cardiac surgeries.
