Each disposable CP injection electrode has a 1 mm active tip and typically is used for stimulation-guided blocks, in which a nerve stimulation signal is first applied to position the electrode, and then anesthetic solution is injection to block the nerve. Each probe come sterile-packed and is tissue-piercing. Its long, flexible fluid line enables the physican to keep his/her hands out of the x-ray beam while administering contrast medium, and reduces disruption of the needle position during injection.
The CP electrode has a discrete, ergonomic hub for clear fluoroscopic views and comforable handling. A marker on the hub indicates the orientation of the bevel opening of the 1 mm active tip. A variety of shaft lengths are available for targeting nerves in different parts of the spine:
The CP injection electrode has a shrouded connector for safe electrical connection to an radiofrequency generator via a ~3-meter cable (CB116).
A variety of cable organizaton options are available for use with the CP injection electrodes:
- The CR cable organizer (CR-CO) keeps the electrical and injection lines of up to six CP needles organized during a procedure. The organizer can be sterilized and clipped to the surgical drapes, and CP needles attached to pins on one side of the organizer. The electical cable from the generator can be easily moved between pins on the other side of the organizer to electrify each CP electrode in turn.
- The G4 cable organizer (G4-CO) keeps the CB116 ~3-meter organzied as the run from the G4 four-electrode RF generator to the surgical field where they are each connected the electrical line of a CP injection electrode.
- Cable:CB116, CB116-4, C116
