Dear Salon Chen:

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.

As shown in the above comparison Table, the proposed device is in similarity to the predicate device. Accordingly, the proposed devices are substantially equivalent to the predicate Endo Motor (K203320).

Design and Technology – The basic design and technology of providing Endo Motor is the same or similar.

Performance and Specifications – The subject device has similar handpiece system and specifications to the predicate device.

{11}

Indications – The indication is identical with the predicate device.

## 8.3. Review of Differences:

**Note1:**

There are differences in the handpiece dimensions and weight between the proposed and predicate devices. The proposed devices have a cylindrical handle design with a slightly shorter length compared to the predicates. The proposed devices have passed usability compliance testing for their intended use. The weight reduction, combined with the ergonomic design, does not compromise the device's structural integrity or performance. Therefore, these differences do not introduce any new safety or effectiveness concerns when compared to the predicate devices.

**Note2:**

There is the difference in the torque range as compared to the predicate, however it is adjustable in the main unit by the operator, the device provides auto reverse and stop function when motor bear the torque resistance higher than the setting torque and the device comply with IEC80601-2-60 requirements, this difference would not affect its safety and effectiveness.

**Note3:**

The rotation speed of the prosed device is within the speed of the predicate device, thus substantially equivalent, the difference would not affect its safety and effectiveness.

**Note4:**

There is the difference in Primary Contra Angle Gear Ratio as compared to the predicate, Contra Angle Gear Ratio is tested, the difference would not affect its safety and

{12}

effectiveness.

## 9. Discussion of Non-clinical Tests Performed for Determination of Substantial Equivalence are as follows:

The proposed device is the same as the predicate device but the two devices are different. A series of safety and performance tests were conducted on the subject device:

- Biocompatibility Assessment per ISO 10993-1
- Reprocessing Validation (cleaning, disinfection, sterilization)
- Software Validation
- Electromagnetic compatibility and electrical safety
- Function test

All the test results demonstrate the Endo Motor meets the requirements of its pre-defined acceptance criteria and intended uses, and is substantially equivalent to the predicate device.

## 10. Clinical Tests Performed

No clinical test data was used to support the decision of substantial equivalence.

## 11. Conclusion

The subject devices have all features of the predicate devices. The few differences do not affect the safety and effectiveness of the subject devices.

Thus, the subject devices are substantially equivalent to the predicate devices.
