The ArthroCare Quantum system (Model RF 12000) and ArthroCare Quantum 2 System (Model RF 12000)are bipolar, radiofrequency (RF) electrosurgical systems designed for use in arthroscopic and orthopedic procedures.
Indications for Use
The ArthroCare Quantum (RF 12000) System and ArthroCare Quantum 2 System (RF 12000) are indicated for resection, ablation, and coagulation of soft tissue and hemostasis of blood vessels in arthroscopic and orthopedic procedures.
The ArthroCare Quantum (RF 12000) System and ArthroCare Quantum 2 System (RF 12000) are contraindicated in any procedures where a conductive solution is not used.The System is also contraindicated for patients who have cardiac pacemakers or other electronic implants without specific instructions from the manufacturer of the cardiac pacemaker or implant. Please refer to the Wand Instructions for Use for a more comprehensive list of contraindications regarding specific procedures. The controller is not intended to be used with a neutral electrode.
Principle of Operation
The ArthroCare Quantum (RF 12000) Controller and ArthroCare Quantum 2 System (RF 12000) are designed to deliver RF energy to the electrode elements located at the distal end of the sterile single-use Wands. Current flows between the active electrode elements and the return electrode element, both elements or poles located on the Wand itself in a bipolar configuration, providing a localized energy field. The result of this arrangement is controlled energy delivery with minimal collateral tissue damage.
The ArthroCare Quantum (RF 12000) System and ArthroCare Quantum 2 System (RF 12000) work by passing RF energy through a conductive solution (such as normal saline or Ringer‟s lactate) in close proximity to or in contact with the tissue to be treated. The conductive solution forms a thin layer between the active and return electrode elements. In the ablation mode, when sufficient energy is applied, the conductive solution is converted into a vapor layer (plasma) containing energized charged particles.
When the high-energy charged particles come in contact with tissue, they cause its
disintegration through molecular dissociation. This mode of operation results in relatively low treatment site temperatures when compared to conventional electrosurgical and monopolar RF systems, thus yielding limited collateral thermal damage to the surrounding untreated tissue.
The system can also function when a lower voltage is applied between the active and return electrodes. In this case, the electrical field is below the threshold required to create a plasma layer and resistive tissue heating occurs. This mode is useful when a greater thermal effect is needed, i.e. for coagulation of setting will depend on the design of the Wand used, tissue type, and desired tissue effect.
