S&T ART-12 Arteriotomy Clamp Hole size in the tip 1.2mm
Acland-Banis Arteriotomy Clamp
The Acland-Banis Arteriotomy Clamp was developed to overcome the difficulties of creating a hole in the side of a vessel, in an end-to-side anastomosis. The device enables the surgeon to make an arteriotomy with an instrument that cuts the vessel the best - a knife. The arteriotomy clamp picks up and holds the piece of the vessel wall that is to be excised. Then, with a single curving sweep of a straight blade that is held close against the clamp tip, the ellipse is excised. The result is a perfect arteriotomy, every time.
The Clamp is Precision made-made, cross-action forceps with a heavy closingpressure and a tapered fenestrated tip. The hole in the tip is important because the tissue that is picked up can squeeze into and held firmly. There are three sizes of clamp 1.2mm, 1.8mm and 2.4mm in diameter. Each clamp can cut a different hole size , depending on the depth of the tissue being picked up. Using the set of three clamps holes can be cut achieving a mean diameter ranging from 1 to 5mm
The Perfect Hole
A good arteriotomy is essential for an end-to-side anastomosis. The hole should be elliptical and clean-cut, with even, steeply sloping edges. The hole should not have an irregular, ragged edge as it may weaken the wall and attract thrombosis. A well-made hole allows the surgeon to see the edges clearly, place the needle accurately, and tie sutures securely. Such a hole is hard to make, as every micro-vascular surgeon knows. Scissors just won't cut it.
