Intended Use

The hekaDrill system is intended for use in surgical procedures involving incision / cutting, removal, drilling and sawing of soft and hard tissue, bone and biomaterials. The system is specifically intended for use in Neurosurgical (Cranial including craniotomy); Ear, Nose and Throat (ENT), Maxillofacial, Orthopedic, Arthroscopic, Spinal, Stemotomy, and General Surgical Procedures.

Device Story

hekaDrill system comprises electric and pneumatic drill handpieces, power console, footswitches, attachments, and cutting tools; used for incision, cutting, removal, drilling, and sawing of soft/hard tissue, bone, and biomaterials. Operated by surgeons in clinical settings (neurosurgical, ENT, orthopedic, etc.). System transforms electric or pneumatic energy into mechanical rotation to drive interchangeable cutting tools. Irrigation tube kits provide fluid management. Handpieces, attachments, and accessories are reusable; cutting tools and irrigation kits are single-use sterile. Device provides surgeons with precise tissue manipulation capabilities; performance validated against predicate systems for vibration, noise, and control. Clinical benefit derived from efficient tissue removal during complex surgical procedures.

Clinical Evidence

Bench testing only. Performance validation compared cutting performance (vibration, noise, control) against predicate systems, demonstrating equivalent or superior results. Electrical safety confirmed per IEC 60601-1:2005; electromagnetic compatibility per IEC 60601-1-2:2014. Biocompatibility testing (L929 MEM Elution, Kligman Maximization, Intracutaneous Injection, Systemic Toxicity, Pyrogenicity, and Indirect Hemolysis) confirmed the device is non-cytotoxic, non-sensitizing, non-irritant, non-toxic, non-pyrogenic, and non-hemolytic.

Technological Characteristics

System includes electric/pneumatic handpieces, power console, footswitches, and attachments. Powered by electricity or pneumatic air. Reusable handpieces/attachments; single-use sterile cutting tools/irrigation kits. Conforms to IEC 60601-1 (electrical safety) and IEC 60601-1-2 (EMC). Materials verified via biocompatibility testing (ISO 10993 standards implied).

Indications for Use

Indicated for surgical procedures involving incision, cutting, removal, drilling, and sawing of soft and hard tissue, bone, and biomaterials in neurosurgical, ENT, maxillofacial, orthopedic, arthroscopic, spinal, sternotomy, and general surgical procedures.

Dear Faith Robertson:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

### XI. Comparison of the Technological Characteristics

The primary predicate (Skeeter Ultra-Lite Oto-Tool Drill system) consists of a dedicated electric handpiece, consoles, footpedals and a range of cutting accessories. The primary predicate device is similar to the system under review in that electric energy is used to supply power to the handpiece which then operates interchangeable cutting tools. Both systems have ENT specific indications for use.

In addition, the secondary predicate devices (Midas Rex Drill Systems) are currently available on the market consisting of both pneumatic and electric handpieces, consoles, footpedals, attachments, cutting tools and system accessories. The secondary predicate devices are similar to the system under review in that air or electric energy is used to supply power to the handpiece which then operates interchangeable cutting tools that are supported by interchangeable attachments. Both systems have the same indications for use and both use similar materials.

In summary, a full comparison between the predicate devices and the hekaDrill system demonstrated that any of the differences between the devices do not have an impact on safety and effectiveness or its ability to perform its intended use.

#### XII. Discussion of the Performance Testing

The following testing has been performed on the hekaDrill system in order to demonstrate the functionality of the device. A summary of this testing is as follows:

| Test performed | Description of testing | Conclusion |
|---------------------------------------------|----------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------|
| General Performance | | |

| Electrical Performance | | |
| Electrical Safety | Electric powered instruments evaluated<br>for electrical safety | Instruments conform to IEC 60601-<br>1:2005 for electrical safety. |
| Electromagnetic<br>Compatibility | Electric powered instruments evaluated<br>for electromagnetic compatibility | Instruments conform to IEC 60601-1-<br>2:2014 for electromagnetic<br>compatibility. |
| Biocompatibility | | |
| Cytotoxicity – L929<br>MEM Elution | There was no biological reactivity<br>(Grade 0) of the cells exposed to the test<br>article extract. | Non-cytotoxic |
| Sensitization –<br>Kligman<br>Maximization | The extracts of the test article, elicited<br>no reaction at the challenge (0%<br>sensitization) | Non-sensitizer |
| Irritation –<br>Intracutaneous<br>Injection | The test article sites did not show a<br>significantly greater biological reaction<br>than the control article. | Non-irritant |
| Systemic Toxicity | The test article did not induce a<br>significantly greater biological reaction<br>than the control extracts. | Non-toxic |
| Pyrogenicity | The test article did not induce a<br>Pyrogenic response. | Non-pyrogenic |
| Indirect Hemolysis | The test article led to a hemolysis index<br>above the negative control of 0.14%. | Non-hemolytic |

### XIII. Conclusions

The hekaDrill system is substantially equivalent to the predicate devices, as shown through comparisons and testing.
