Method of using flexible spinal needle assemblies

摘要

A method of using an assembly to insert a flexible spinal needle and minimize incidence of post dural puncture headache is provided. The assembly typically includes a support needle with a non-cutting piercing tip and an exteriorly mounted flexible needle. The flexible needle gauge may be reduced, while ease of use is increased by the exterior mounting. The flexible needle provides increased flexibility allowing for movement of a patient's torso after insertion. A central stylet may be included to prevent entry of matter into the support needle opening during insertion. In other embodiments, methods for allowing single stick insertion procedures to provide better placement by allowing placement to be determined and adjusted based on physical feedback obtained during the single stick insertion.
