If the surgeon needs to obtain a biopsy of cerebral tissue through a bur hole, which needle should the surgical technologist acquire?

The Dorsey needle is specifically designed for obtaining tissue samples, including brain tissue, through a relatively small access point like a bur hole. Its design allows it to effectively penetrate soft tissue while minimizing trauma to surrounding structures, making it particularly suitable for delicate tasks such as cerebral biopsies.

This needle has the features necessary for accessing deep structures in the brain with precision, which is critical in neurosurgical procedures. It enables the surgeon to collect a core sample of tissue, essential for accurate pathological assessment and diagnosis.

While other needles may have specific applications in different contexts, they do not match the specificity and suitability of the Dorsey needle for cerebral biopsy procedures through a bur hole.
