A specialist surgical tool for tiny blood arteries with dimensions between 0.6 and 1.5 mm is the B Double Clamp.6-1.5mm Frame. It is commonly employed in cardiac procedures, microsurgeries, and vascular surgeries where accurate blood vessel approximation and stabilization are crucial. This clamp reduces the possibility of vessel injury while enabling the surgeon to safely hold and work with tiny vessels for anastomosis, grafting, or repair.
