Collection: Microvascular clamps

Both finishes reduce glare; the matte finish provides a non‑reflective dark grey surface, while the black finish minimizes eye fatigue and prevents burnout in surgical photography. Hospitals and distributors can select the finish that best suits their operating‑room lighting.

Large sizes (RD and HD) are applied manually using the clamp’s corrugated gripping surface. Smaller sizes (B‑1, B‑2 and B‑3) should be applied with a clamp applicator forceps; squeezing the forceps opens the clamp and allows precise placement without risking calibration damage.

The all‑purpose ‘V’ pattern is used for most veins and arteries; the ‘A’ pattern has a slight incurve that provides extra security on thick‑walled or slippery arteries. Selecting the appropriate pattern helps prevent slippage and vessel trauma.

Clamp size corresponds to vessel diameter; each size has a calibrated closing force so that pressure is 5 g/mm² on the largest recommended vessel and 15 g/mm² on the smallest. Surgeons should not use a clamp on a vessel smaller than the recommended range, as excessive pressure could damage the vessel. There is a 50 % overlap between sizes, so choose the smaller clamp when in doubt for gentler handling.

Two‑jaw approximator clamps temporarily occlude arteries or veins during microvascular surgery. They have light, compact, corrosion‑resistant bodies and parallel jaws that gently hold vessels for anastomosis. These clamps are also used to manipulate tissues, allowing surgeons to improve visibility and precision during microvascular repairs. These clamps are the workhorse for most microvascular repairs.
