Thanks！ * This is one of my favorite Mammotome design features – not because it’s big, but because it shows the level of detail which can be achieved with a single-minded focus. Vacuuming the tissue and then severing the tissue from the breast happens virtually at the same time. But they are both very different functions. And while cutting tissue may seem routine, it’s definitely not. There are a wide variety of tissue and lesion types, which require the cutting technology be just as sharp and precise as the blade technology in the first element--access. To obtain the most precise cut, we have designed Mammotome with a 28 degree aperture. It’s unique to Mammotome and no other system has this feature. The Angled Bowl geometry was developed to act as a “scissor” to assure the proximal and distal edges of the sample are as clean as the center portion. Think of the office paper-cutter design. It’s not at 90 degrees, but rather at 28 degrees, right? Why is that? It’s a smaller surface to cut at 28 degrees vs. 90 degrees. Our cutting technology versus the competition’s is like the difference between cutting a stack of papers or fabric with dull scissors versus sharp ones – and as any seamstress, beautician or barber will tell you, the sharper the cutting edges, the cleaner and more precise the cut is. They wouldn’t think of working with substandard blades, and neither would we. * The next step is completion of the transection. The probe on the right is a common option, and you can see the rounded end of the tube in the needle’s dead space. There is no perpendicular edge to sever the tissue sample. In essence, it pinches the tissue to amputate the sample. The Mammotome on the left has our unique, patented Tissue Stop technology. The 4.5mm post allows our high-speed, rotating cutter to cut beyond the distal end of the sample for a clean cut against a flat, perpendicular surface. Rather like a butcher-block a sharp knife can cleave cleanly. In addition, A time del
