Vascular Clamps: Jaw Patterns, Atraumatic Design and Sizing by Vessel

What makes an atraumatic vascular clamp atraumatic

An atraumatic vascular clamp has jaws with fine, shallow serrations, usually in the form of longitudinal rows of tiny teeth that interlock gently. These distribute the clamping force over a wide area, so the vessel is held securely at low pressure without crushing the intima, which could cause thrombosis or later stenosis.

Jaw length, shape and the spring or ratchet determine how the clamp behaves. Clamps are locked with a ratchet, so surgeons need a mechanism that closes cleanly and releases without a jolt to the vessel.

DeBakey clamp and Cooley clamp patterns

The DeBakey clamp is one of the most widely used atraumatic patterns, with longitudinal serrations on straight or angled jaws and several jaw lengths. DeBakey patterns are made for the aorta and peripheral vessels, and for paediatric work.

The Cooley clamp has jaws that are typically angled to approach the vessel from a convenient direction, and is available in versions for the aorta, peripheral vessels, multi-purpose use and in paediatric and neonatal sizes. REDA's cardiovascular and thoracic section lists DeBakey and Cooley clamps in aortic, peripheral, multi-purpose, pediatric and neonatal versions.

• Aortic versions for large vessels
• Peripheral versions for limb and neck vessels
• Multi-purpose versions for general vascular work
• Paediatric and neonatal versions for small vessels

Satinsky clamp and partial occlusion

The Satinsky clamp has curved jaws that can be closed over part of a large vessel wall, allowing side-biting occlusion. It is used when the surgeon needs to clamp part of the aorta or vena cava, create an anastomosis and still maintain flow through the remaining lumen.

REDA's range also lists coarctation and anastomosis clamps, along with Dardik multi-purpose clamps and Castaneda neonatal clamps for specialised cardiac work. Titanium atraumatic clamps, bulldog clamps and Johns-Hopkins serrefines are listed in its forceps and clamps range.

Choosing clamp patterns and sizes

Build the clamp list around the vessels you will occlude. Large vessels need long-jawed clamps; peripheral and small vessels need shorter, lighter ones; bulldog clamps and serrefines are used for small vessels and branches, where a light clamp reduces the risk of trauma. Always keep a range of sizes in each vascular tray.

Ask the surgeons which patterns they use and whether they need duplicates for cases where several vessels are clamped at the same time. For wider guidance, see our articles on vascular surgery instruments and cardiothoracic surgery instruments.

Inspection, care and buying in the UAE

On receipt, close each clamp and check that the jaws meet along their whole length, then hold it to the light to see that no gaps remain. Check the ratchet and the smoothness of the box joint. Clean jaw serrations with a soft brush, avoiding anything that could damage the fine teeth, and sterilize by steam in line with ISO 17665 practice.

Confirm product registration with the relevant UAE authority. Beckfinity's specialists can prepare a quotation for atraumatic vascular clamps from the REDA catalogue.
