Indications for Use
Laminectomy Rongeurs, Kerrison 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
Reusable manual stainless steel surgical instruments; includes Laminectomy, Kerrison, and IVD Rongeurs. Devices feature fixed/sliding shafts, angled footplates, or hinged mouthparts; various handle styles, surface finishes, and coatings available. Operated by surgeons in clinical settings to cut or bite bone. Kerrison models include optional cleaning channels and push-button or lever-based opening mechanisms for reprocessing. Devices are provided non-sterile and require steam sterilization before use. Performance relies on mechanical force applied by the user to the handle to actuate the jaw/biting mechanism. Equivalent to predicate rongeurs in design, function, and intended use; differences in opening mechanisms do not impact safety or effectiveness.
Clinical Evidence
Bench testing only. Validated automatic reprocessing (AAMI TIR 30) confirmed removal of soil/microbiological contamination. Sterilization validation achieved SAL 10^-6. Corrosion resistance verified via boiling test (ASTM F1089-10). Biocompatibility testing (ISO 10993-5, ISO 10993-10) confirmed non-cytotoxic and non-irritating properties. Mechanical testing compared handle/cutting forces against predicates, demonstrating equivalent or superior performance.
Technological Characteristics
Materials: Stainless Steel AISI 420 A, Titanium (ASTM F136 / ISO 5832-3). Design: Manual, reusable, stainless steel instruments; various shaft lengths (6-15 inches), jaw sizes (1-6 mm), and angles. Features: Cleaning channels, push-button/lever opening mechanisms, silicone-coated handles, and various surface coatings (ceramic, black, gold). Energy: Manual. Sterilization: Steam sterilization (non-sterile delivery).
Indications for Use
Indicated for cutting or biting bone during skull or spinal column surgery in patients aged two years or older.
Regulatory Classification
Identification
A manual rongeur is a manually operated instrument used for cutting or biting bone during surgery involving the skull or spinal column.

| Automatic Repro-<br>cessing Validation<br>"Panther Kerrison<br>Rongeur"<br>+<br>Amendment to<br>Automatic Repro-<br>cessing Validation<br>"Panther Kerrisson<br>Rongeur. | The test was performed to verify that the devices could be<br>cleaned with the provided cleaning steps in the IFU.<br><br>This test method is performed by contamination of accessi-<br>ble, interior, and exterior surfaces of instruments intending<br>to reach the sites identified as the least accessible or most<br>difficult to reach sites (worst case).<br><br>According AAMI TIR 30, the effectiveness of the repro-<br>cessing cycle is evaluated by comparing visible contamina-<br>tion (red blood cells), residual protein, the number of organ-<br>isms and TOC level recovered from the control instruments<br>and the test instruments. | This validation provides evidence<br>that viable microbiological contami-<br>nation as well as a soil contamina-<br>tion of the "Panther Kerrison<br>Rongeur" are removed by the given<br>cleaning and disinfection instruc-<br>tions |
| Sterilization testing | The test is to verify that the devices could be sterilized with<br>the provided sterilization procedure described in the IFU.<br><br>The test specimens were contaminated with bioindicators<br>or with a challenge suspension and were tested for sterility<br>after the sterilization process.<br><br>To assure a SAL of $10^{-6}$ only a part cycle of the recom-<br>mended sterilization process was performed in validation. | A reduction of test bacteria was<br>observed and assured showing that<br>contaminated test specimens are<br>free of viable/augmentable bacteria<br>after sterilization. |
| Boiling Test | This test is to verify the corrosion resistance of the instru-<br>ments.<br><br>It is performed according ASTM F1089-10 section 6.1.<br>Devices are boiled in distilled water for 30 min, cooled<br>down in the water for 3 h and dried at air for 2 h.<br>Devices were not allowed to show signs of corrosion. | The tested instruments did not show<br>any signs of corrosion. |
| Cytotoxic testing | Test is to show, that no toxic residuals from manufacturing<br>remained on the device.<br><br>The test was performed with finished devices from all the<br>different materials and coatings according ISO 10993-5.<br>Devices must be considered non cytotoxic. | All the tested samples were consid-<br>ered to be NON CYTOTOXIC. |
| Irritation testing | The objective of this study was to determine if device-<br>extracts produced an irritation reaction when injected intra-<br>cutaneously in rabbits.<br><br>Test was performed according ISO 10993-10 with finished<br>devices in all material-coating configurations.<br><br>Devices were extracted in 0.9 % saline and cottonseed Oil<br>for 72 h.

| Mechanical testing<br>- handle force<br>- bite force<br>- extended use | Mechanical tests were performed to compare functional<br>requirements of the K2 Rongeurs with the predicate devic-<br>es.<br><br>Therefore the handle force for actuating the device was<br>measured as well as the force to cut artificial bone material.<br><br>Further on the cutting force and cutting size of new instru-<br>ments was measured and compared to worn out instru-<br>ments with the artificial bone material.<br><br>Devices has to perform similar or better than predicate<br>devices. | Test showed that the measured<br>functional specifications of the K2<br>Rongeurs were equivalent or better<br>than the comparable specifications<br>of the predicate devices. |
The nonclinical testing demonstrated, that the K2 Rongeur is substantial equivalent to the predicate device and performs as well as or better than the legally marketed predicate devices.

## 7. Substantial Equivalence
Substantial equivalence for the K2 Ronqeurs is based on similarities in intended use, design (function, dimensions, operational principles and performance tests), materials and labeling based on their promotional materials, labeling and clearance letter.
The only difference to the predicate devices is another opening mechanism with a push button for the K2 Kerrison Rongeurs. By pressing the push button the upper part of the shaft can slide back and is released from the guide of the lower part. It can easily be opened for cleaning. After cleaning the upper part is laid down to the lower part and snapped in by pressing the handle.
The predicate device from Integra and from Instrumed has a lever to release the upper part from the quide of the lower part.
The minor technological differences between the K2 Rongeurs and the predicate devices raise no new issues of safety or effectiveness.
Performance data demonstrate, that the K2 Rongeurs do comply to relevant standards and that their main functional features are equivalent to the predicate devices from Integra and Instrumed. Thus, the K2 Rongeur is substantially equivalent to the predicate device.
