A regulating device for variably regulating the length of a combined spinal epidural needle and the method of practicing same is disclosed. In one variant, the regulating device features a pair of substantially concentricity disposed sliding members to which each of the epidural needle and spinal needle may be separately fitted. A spring element is provided to selectably engage the spinal needle. The spring element includes one end fixed to the sliding member securing the epidural needle, a free end manipulable by a user, and at least one passage or opening disposed between the fixed and free ends through which the spinal needle passes. The opening is configured to permit either gripping or free sliding of the spinal needle depending on the practitioner's actuation of the spring element. By actuation of the spring element, the practitioner may control axial movement between the sliding members, thereby regulating the extension of the spinal needle relative to the epidural needle. The sliding members may be configured in a variety of shapes or dimensions to accommodate various combinations of spinal and epidural needles. The device may be provided pre- assembled with either one or both of the spinal needle or epidural needle, or it may be employed with a spinal needle, epidural needle, or both separately sourced.
