A cranial trephine is a neurosurgical tool designed to create precise, circular openings in the skull to access the brain. Clinically, it is used for procedures like catheter insertion, neuroscope-guided diagnostics, or relieving intracranial pressure by removing bone sections or obtaining cerebrospinal fluid samples.
These devices are typically single-use, made of durable materials like stainless steel, and attach to either manual or powered handpieces. Regulation varies by jurisdiction, but they are generally classified based on their surgical risk and intended use, with compliance requirements tied to their sterile, disposable nature and precision engineering.
