Safety Communication – Cranial Perforators With an Automatic Clutch Mechanism: Failure to Disengage

Most cranial perforators are designed to automatically stop drilling after penetrating the skull to prevent the tip from unintentionally drilling or “plunging” into the brain. However, this clutch mechanism may fail to disengage if proper use, patient considerations, and device selection are not followed in accordance with the manufacturer’s instructions for use. The clinical consequences of cranial perforators failing to disengage can be serious. [9/29/15]
