No
The device description explicitly mentions hardware components like the "7D Surgical Flash Frame" and "7D Surgical Reference Frame" which are physically attached to the patient. It also describes acquiring an "intra-operative tomographic scan" and a "3D structured light image," implying the use of imaging hardware. The predicate device also lists several hardware components.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The 7D Surgical System is a surgical navigation system. It uses imaging and spatial positioning to guide surgeons during procedures. It does not analyze biological specimens from the patient's body.
- Intended Use: The intended use clearly states it's for "spatial positioning and orientation of spinal surgical instruments" and as a "primary surgical luminaire." This is a surgical tool, not a diagnostic test performed on a sample.
The device's function and intended use fall under the category of surgical guidance systems, not in vitro diagnostics.

Device Description
The 7D Surgical System is intended for use as a stereotaxic image guided surgical navigation system during minimally invasive spine surgery. The system performs Percutaneous image guided surgery by acquiring an intra-operative tomographic scan of the patient with the 7D Surgical Flash Frame attached to the patient's skin over the incision drape in the region of interest where the spine surgery is to be performed. In addition, the intra-operative tomographic scan is taken with the 7D Surgical Reference Frame rigidly attached to either the spine or iliac crest. The 7D System then generates a three-dimensional (3D) image of the surgical site and the 7D Flash Frame. Registration is performed by the system software registering points from the 7D Flash Frame generated from the 3D intra-operative tomographic scan to the 3D structured light image generated by the system.
The major difference between the previous spine application and the proposed Percutaneous Application is that registration is now performed using the sterile single use Flash Frame. Similar to the previous Registration Frame, registration is performed by picking landmarks on the frame which is placed on the patient drape above the patient skin. Verification of the registration must be confirmed by using a tracked navigational tool on the boney anatomy of the spine prior to navigation. It should be noted that there have been no changes to the previous 7D Surgical System hardware and Percutaneous tool sets with exception to the introduction of the Flash Frame and the Percutaneous Application to enable use of this new instrument.

3. Substantially Equivalent Devices
7D Surgical believes the 7D Surgical System and Percutaneous Application is substantially equivalent to the following currently marketed devices:
| Product | 510(k) |
|---|---|
| 7D Surgical Percutaneous Application (7d Registration Frame, 7d Flex Iliac Pin Connector, 7d Pin Guide Block, 7d 3.2 Mm Steinmann Pin, 7d Iliac Crest Pin Chuck & Key) | K210457 - Primary Predicate |
5
The indications for use of the subject device 7D Surgical System are equivalent to the predicate device K210457. Furthermore, the technological characteristics of the 7D Surgical System are substantially equivalent. The differences in the technological characteristics do not raise new questions of safety and effectiveness. Consequently, the subject is substantially equivalent to the predicate device.
4. Purpose of Submission
The proposed change for the 7D Surgical System is to introduce the 7D Surgical Flash Frame for the previously cleared Percutaneous Application (K210457) which provides minimally invasive image guided spine surgery. Similar to the previous 7D Surgical System K210457, the device registers tomographic DICOM data to structured light images which utilizes intra-operative tomographic scans.
The proposed application intends to introduce the Sterile, Single Use Flash Frame which is applied above the patient skin over the patient drape, similar to the currently cleared 7D Registration Frame, in the region of interest where registration is intended. The major change from the previous Registration Frame is that the proposed Flash Frame has no marker posts to attach optical marker spheres which track the position of the frame in relation to patient Reference Frame during structured light acquisition. In addition, the Flash Frame is provided sterile as opposed to the previous non-sterile Registration Frame.
5. Indications for Use
The 7D Surgical System Percutaneous Application is a stereotaxic image guidance system intended for the spatial positioning and orientation of spinal surgical instruments used by surgeons. The system is also intended to be used as the primary surgical luminaire during image guided surgery. The device is indicated for posterior approach spine surgery where reference to a rigid anatomical structure can be identified.
6. Device Description and Technical Comparison to Predicate Devices
The 7D Surgical System is intended for use as a stereotaxic image guided surgical navigation system during minimally invasive spine surgery. The system performs Percutaneous image guided surgery by acquiring an intra-operative tomographic scan of the patient with the 7D Surgical Flash Frame attached to the patient's skin over the incision drape in the region of interest where the spine surgery is to be performed. In addition, the intra-operative tomographic scan is taken with the 7D Surgical Reference Frame rigidly attached to either the spine or iliac crest. The 7D System then generates a three-dimensional (3D) image of the surgical site and the 7D Flash Frame. Registration is performed by the system software registering points from the 7D Flash Frame generated from the 3D intra-operative tomographic scan to the 3D structured light image generated by the system.
6
The major difference between the previous spine application and the proposed Percutaneous Application is that registration is now performed using the sterile single use Flash Frame. Similar to the previous Registration Frame, registration is performed by picking landmarks on the frame which is placed on the patient drape above the patient skin. Verification of the registration must be confirmed by using a tracked navigational tool on the boney anatomy of the spine prior to navigation. It should be noted that there have been no changes to the previous 7D Surgical System hardware and Percutaneous tool sets with exception to the introduction of the Flash Frame and the Percutaneous Application to enable use of this new instrument.
7. Safety Considerations
This change to add compatibility to the 7D System to include navigational tracking of the Percutaneous Application did not impact conformity to regulatory compliance standards as only the system software has been modified to support this new feature. Software, Mechanical Design, and User Instructions risk control measures have been implemented to ensure all new risks associated with use of the Percutaneous Application have been adequately controlled.
8. Technological Characteristics
The literature research and the comparison to the predicate devices show that the device makes use of equivalent technological characteristics and functionality and is intended for equivalent surgical procedures as compared to the predicate devices.
9. Nonclinical Performance Data
Verification and Validation activities have been conducted to provide assurance that the device meets the performance requirements under the indications for use conditions.
7D Surgical performed the following testing to demonstrate equivalence to the predicate device:
- Non-Clinical System, Software, and Instrumentation Verification and Validation
- Non-Clinical Performance Surgical Simulations Conducted on Phantom Models
- Compliance Conformity Assessments ●
- Sterilization and Packaging Validation Studies for 7D Surgical Flash Frame ●
Device performance tests were performed to verify the absolute accuracy and repeatability of the accuracy of the device, and the navigation accuracy. Target Registration Error (TRE)
7
has been used to evaluate the simulated accuracy of the system on phantom models in a simulated environment. TRE evaluates the error discrepancy between the position reported by the image guided surgery system and the ground truth position measured physically or otherwise.
The following table contains a summary of verification and validation performed on the 7D Surgical System:
| Verification and Validation | Description | Conclusion |
|---|---|---|
| System Verification | Scope of the test is to verify the | |
| design requirement | ||
| specifications of 7D Surgical | ||
| System under test case | ||

| System Validation | Scope of the test is to validate | |
| the Indications For Use and | ||
| Customer Requirements of the | ||
| 7D Surgical System under | ||
| simulated use case situations. | Validation successful, all user | |
| needs met. | ||
| Safety regarding risk analysis | Implementation and | |
| effectiveness of all risk control | ||
| requirements specified in the | ||
| 7D Surgical System risk | ||
| analysis are tested and | ||
| verified. | Risk Control requirements are | |
| effective and mitigate the | ||
| associated risks to an | ||
| acceptable level. | ||
| Non-Clinical Accuracy | System's accuracy is tested | |
| using the 7D Surgical System | ||
| on phantom models using | ||
| Target Registration Error. | All accuracy specifications | |
| have been met for the | ||
| Percutaneous Application. |
All non-clinical tests successfully passed demonstrating that the subject device performs as safely and effectively as the predicate device and supporting substantial equivalence.
10. Clinical Data
A clinical trial was not required to demonstrate safety and effectiveness of the 7D Surgical System. Clinical validation is unnecessary as the 7D Surgical System introduces no new indications for use, and device features are equivalent to the previously cleared predicate device identified.
11. Conclusion
The 7D Surgical System is substantially equivalent in safety and effectiveness to the predicate devices identified above:
- The predicate devices and 7D Surgical System use equivalent technologies.
- The predicate devices and 7D Surgical System are designed and manufactured to the similar electrical and physical safety standards.
The non-clinical verification and validation performed demonstrate that the 7D Surgical System Percutaneous Application meets design specifications. The conclusions drawn
8
from the non-clinical tests demonstrate that the 7D Surgical System performs as safely and effectively as the legally marketed predicate device according to the comparison based on the requirements of 21 CFR §882.4560 and the information provided herein. It is concluded that the 7D Surgical System is substantially equivalent to the predicate device with respect to its indications for use, technological characteristics, and performance characteristics.
