A neurosurgical retraction cannula is a single-lumen surgical instrument used to gently move brain tissue aside during procedures, allowing surgeons to reach deep-seated lesions or abnormalities without cutting through tissue. It is typically inserted with an obturator to create a working corridor between natural brain structures like gyri, and may feature depth markings to guide placement.
This category consists of single-use devices made from polymer materials, often supplied with a disposable obturator. As single-use instruments, they are intended for one procedure only and are not reprocessed or reused.
