• Attributes: Therapeutic

Intended Use

The Dyonics ElectroBlade is indicated for use in arthroscopic surgical procedures of large and small articular cavities for resection and excision of soft and osseous tissues and for coagulation of bleeding.

Device Story

Dyonics ElectroBlade combines rotary mechanical cutting with monopolar electrosurgical coagulation; device consists of inner rotational blade electrified via connection to standard electrosurgical generator and outer blade with insulation to focus energy at cutting window. Used in arthroscopic procedures by surgeons to resect/excise soft and osseous tissues while simultaneously coagulating bleeding. Operates in conjunction with standard Dyonics shaver system and standard monopolar electrosurgical generator; requires use of electrosurgical dispersive pad. Benefits include combined mechanical and electrosurgical functionality in single instrument, reducing need for tool exchanges during arthroscopy.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Monopolar electrosurgical probe combined with rotary mechanical shaver blade. Features insulated outer blade to isolate electrical energy to inner tube cutting window. Requires external electrosurgical generator and dispersive pad. Mechanical/electrical integration.

Indications for Use

Indicated for patients undergoing arthroscopic surgery of large and small articular cavities requiring resection/excision of soft and osseous tissues or coagulation of bleeding.

Regulatory Classification

Identification

| Common Name: | Arthroscopic Surgery Blade/Electrosurgical Probe |
| Classification Name: | Electrosurgical Probe |

#### D. Predicate Devices

The Dyonics ElectroBlade is substantially equivalent in design, materials, function and intended use to the following devices in commercial distribution: Dyonics Arthroscopic Surgery Blades, Dyonics Electrosurgical Switchpen and Probes.

### E. Description of Device

The Dyonics ElectroBlade combines the rotary cutting technology of Dyonics Arthroscopic Surgery Blades with the electrosurgical capabilities of a monopolar electrosurgery probe. The inner rotational blade is electrified by connection to a standard electrosurgical generator. Insulation on the outer blade isolates the electrical energy to the inner tube where it is exposed to tissues at the cutting window of the blade. The Dyonics ElectroBlade operates in conjunction with the standard Dyonics shaver system and standard monopolar electrosurgical generator systems. The Dyonics ElectroBlade requires the use of an electrosurgical dispersive pad.

#### P Intended Use

The Dyonics ElectroBlade is indicated for use in arthroscopic surgical procedures of large and small articular cavities for resection and excision of soft and osseous tissues and for coagulation of bleeding.

Dear Ms. Connors:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
