ACRA-CUT is the only company in the world specializing in the development and manufacture of automatic-releasing cranial perforators. Innovations include perforators for thin skull areas, for uneven bone, and for pediatric procedures. . . .And they are available in a wide range of sizes for every surgical application. ACRA-CUT’s patented cammed-lug release mechanism, the safest and most reliable ever developed, eliminates the risk of dangerous penetration. The unique benefits of these perforators are: Inner drill moves forward less than 1mm to automatically release. Sharp edges cut quickly and smoothly so less hand pressure is required. Will not stop drilling before the burr hole is completed. Can be stopped and started as the surgeon requires. Non-skid tip prevents the perforator from sliding on the skull during start-up. Inner drill forms a bone pad to protect the dura. Rigorous testing makes ACRA-CUT perforators the safest in the world. Each reusable perforator drills 21 holes in pretesting. Several models are offered in 14mm/11mm and 11mm/7mm sizes. Easy and risk-free assembly. Perforator cannot be assembled incorrectly. Parts are serialized for easy identification.
