Intended Use

The KLS Martin Neuro Rongeurs are manually operated instruments indicated for cutting or biting bone during surgery involving the skull or spinal column in patients two years of age or older.

Device Story

KLS Martin Neuro Rongeurs are manual, reusable, stainless-steel surgical instruments used to cut or bite bone during cranial or spinal procedures. Devices are provided non-sterile and require user-performed cleaning and steam sterilization. Available in various configurations including different cutting angles (30°-90°), shaft lengths (15-30 cm), jaw widths (1-6 mm), and handle designs; some models feature a push-button mechanism for shaft separation to facilitate cleaning. Operated by surgical specialists in sterile OR environments. Output is mechanical bone resection; healthcare providers use the device to gain access to underlying tissue. Benefits include improved surgical site accessibility and bone removal capability.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical bench testing, including corrosion resistance (autoclave, boiling, copper sulfate tests), thermal resistance, cut quality, and comparative functional testing (spring, cut, and push-button force). Biocompatibility evaluated per ISO 10993 (leachables, cytotoxicity, sensitization, irritation, pyrogenicity, hemocompatibility). Sterilization validated per AAMI ANSI ISO 17665-1.

Technological Characteristics

Materials: Stainless steel (AISI 420A, AISI 303, AISI 301), TiAlN coating, gold plating. Principle: Manual mechanical bone cutting. Dimensions: 15-30 cm shaft length, 1-6 mm jaw width. Connectivity: None. Sterilization: Steam (dynamic-air-removal) per AAMI ANSI ISO 17665-1. Reusable.

Indications for Use

Indicated for cutting or biting bone during surgery involving the skull or spinal column in patients two years of age or older.

Dear Susan Leander:

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 (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 located 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.

#### Technological Characteristics & Substantial Equivalence Discussion

The subject device, KLS Martin Neuro Rongeurs, is comparable in materials, design, composition, and function to the predicate device. K150468. The only differences are in some of the options available, such as cutting angles and shaft lengths. The subject device has jaw widths ranging from 1 mm to 6 mm, which is the same as the predicate device. The subject devices have cutting angles that are equivalent to those of the predicate and reference devices. Cutting angles range from 30° to 90° and can angle up or down. The selection of cutting angles allow for greater accessibility to the surgical site. Shaft lengths range from 6 to 15 inches for the predicate device and from 15 to 30 cm (~6 to ~12 inches) for the subject device. Rongeurs are multipurpose instruments that can be used in a variety of applications to cut and bite bone for access to underlying tissue. All of these options are surgeon's preference and do not raise new questions of safety or effectiveness of the instruments.

| Test Name | Test Description | Result |
|---------------------|------------------------------------------------------------|----------------------------|
| Autoclave Test | Test to verify corrosion resistance<br>during autoclaving. | No corrosion detected |
| Boiling Test | Test to verify corrosion<br>resistance of instruments. | No corrosion detected |
| Copper Sulfate Test | Test to verify corrosion<br>resistance of instruments. | No corrosion detected |
| Thermal Test | Test to verify thermal<br>resistance of instruments. | No corrosion detected |
| Cut Quality | Compare cut quality | Smooth cuts achieved, pass |

#### Comparative Functional Testing

| Test Name | Test Description | Result |
|-------------------|---------------------------|--------------------------------|
| Spring Force | Compare spring force | Comparable to reference device |
| Cut Force | Compare cut force | Comparable to reference device |
| Push Button Force | Compare push button force | Comparable to reference device |

## Biocompatibility Testing

Biocompatibility endpoints were evaluated in accordance with ISO 10993. Biocompatibility testing for chemical characterization of leachables, cytotoxicity, sensitization, irritation, material mediated pyrogenicity and hemocompatibility. Test results indicate that the KLS Martin Neuro Rongeurs are biocompatible.

#### Sterilization Testing

Steam sterilization validations were performed using the dynamic-air-removal cycle in accordance with AAMI ANSI ISO 17665-1 to a sterility assurance level (SAL) of 10° using the biological indicator (BI) overkill method. All test method acceptance criteria were met.

## Performance Testing - Clinical

Clinical testing was not necessary for the substantial equivalence determination.

## Substantial Equivalence Conclusion

KLS Martin Neuro Rongeurs are comparable in materials, design, composition, and function to the predicate and reference devices, K150468, K2 Medical Laminectomy Rongeurs, Kerrison Rongeurs, IVD Rongeurs and K081651, Medline (Instrumed) Rongeurs. They have the same intended use, same fundamental principles of operation, and same technological features as the predicate device. The KLS Martin Neuro Rongeurs are substantially equivalent to the predicate device.
