Cooley Derra S Shaped Clamp Forceps, Curved, 3/4" (19mm) Jaws, Depth 3/8" (10mm), Jaw Has Calibrated Markings In 5mm Increments, Overall Length 6-1/2" (165mm)

This Cooley Derra S‑shaped clamp features calibrated 5mm increment markings etched on the jaw surface, enabling surgeons to quantify vessel wall thickness and compression depth during valve repair or reconstructive work. The 19mm jaw and 10mm depth accommodate smaller vessel segments, while the curved geometry positions the clamp perpendicular to the target vessel without hand rotation.

Features & Benefits

• Calibrated 5mm markings for vessel compression measurement
• 19mm jaw and 10mm depth for precision control
• S‑shaped curve aligns clamp perpendicularly to vessel
• 165mm length supports thoracic positioning
