The device description explicitly mentions hardware components such as a structured light scanner, workstation, wireless optically tracked Spinal Instruments, passive reflective marker spheres, and a surgical luminaire, in addition to the software.
Based on the provided information, the 7D Surgical System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
- 7D Surgical System Function: The 7D Surgical System is a surgical navigation system. It uses imaging data (preoperative scans and intraoperative structured light) to guide the surgeon's instruments during surgery on the patient's body. It does not analyze biological specimens.
- Intended Use: The intended use clearly states its purpose is for "spatial positioning and orientation of spinal surgical instruments used by surgeons" and as a "primary surgical luminaire during image guided surgery." This is a surgical guidance function, not an in vitro diagnostic function.
Therefore, the 7D Surgical System falls under the category of a surgical navigation or image-guided surgery system, not an IVD.

Device Description
The 7D Surgical System is intended for use as a stereotaxic image guided surgical navigation system during spine surgery. The system provides image registration between preoperative scan data and data captured intraoperatively from the 7D Surgical System structured light scanner and/or user selected points. The system provides guidance data by tracking and displaying the position and orientation of wireless optically tracked Spinal Instruments including the 7D Surgical Pedicle Probe and Awl, now including the FlashLock and Flex Rod, relative to the patient. Position and orientation data of tracked Spinal Instruments are linked to the preoperative scan data using the 7D Surgical System workstation. The system is intended to be used as the primary surgical luminaire for image guided surgery. Similar to the previously cleared 7D Surgical System, the system tracks the position and orientation of a FlashLock and Flex Rod.
The system is intended to be used for both image fusion and navigation for neurological applications where reference to a rigid structure can be identified relative to a preoperative image data of the anatomy.
The Tracking System enables the surgeon to view the position and orientation of 7D Surgical System Spinal Instruments relative to registered preoperative image data while performing the surgical procedure. Each of the 7D Surgical System instruments, including the FlashLock and Flex Rod, utilizes commercially available passive reflective marker spheres to determine the position and orientation of instruments. Each tracked Instruments requires a unique marker position configuration to enable the tracking system to distinguish the tools from one to the other.
The Software links all system components and displays navigational data to the surgeon. lt provides methods for loading preoperative scans and guides the surgeon through the process of surface model creation, structured light acquisition, registration, registration verification, and navigation.

3. Substantially Equivalent Devices
7D Surgical believes the 7D Surgical System and FlashLock and Flex Rod is substantially equivalent to the following currently marketed devices:
| Product | 510(k) |
|---|---|
| 7D Surgical System | K180352(primary) and K192140(secondary) |
The indications for use of the subject device 7D Surgical System are equivalent to the predicate device K180352 and K192140. Furthermore, the technological characteristics of the 7D Surgical System are substantially equivalent. The differences in the
4
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 FlashLock and Flex Rod instruments.
The 7D Surgical Flex Rod used in conjunction with the 7D Surgical Flex Array is intended to be used as a patient referencing device when attached to a pedicle screw which has been inserted into the vertebral body. It should be noted that the Flex Array has identical tracking marker sphere configuration as the currently marketed 7D Surgical Reference Clamp. The Flex Array and Flex Rod assembly is identical in intended use to the current Reference Clamp except in the way it is rigidly attached to the spine. The currently marketed 7D Surgical patient referencing device is rigidly attached to the spine by use of an Ikuta Clamp design, whereas the Flex Rod attaches to an already implanted pedicle screw.
The 7D Surgical FlashLock is a ¼" quick connect adapter that has a rotatable tracking marker sphere array. The FlashLock requires a non-tracked insert and handle to be attached to it. Examples of inserts that can be used are drill bits, taps, and screwdrivers that have a ¼" quick connect interface. Examples of handles are T-handles, ratcheting handles or surgical drills. Once calibrated using the 7D Surgical calibration device, the user can rotate the handle and insert while holding the FlashLock array stationary facing the 7D Surgical System tracking camera.
5. Indications for Use
The 7D Surgical System 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 spine surgery. The system provides image registration between preoperative scan data and data captured intraoperatively from the 7D Surgical System structured light scanner and/or user selected points. The system provides guidance data by tracking and displaying the position and orientation of wireless optically tracked Spinal Instruments including the 7D Surgical Pedicle Probe and Awl, now including the FlashLock and Flex Rod, relative to the patient. Position and orientation data of tracked Spinal Instruments are linked to the preoperative scan data using the 7D Surgical System workstation. The system is intended to be used as the primary surgical luminaire for image guided surgery. Similar to the previously cleared 7D
5
Surgical System, the system tracks the position and orientation of a FlashLock and Flex Rod.
The system is intended to be used for both image fusion and navigation for neurological applications where reference to a rigid structure can be identified relative to a preoperative image data of the anatomy.
The Tracking System enables the surgeon to view the position and orientation of 7D Surgical System Spinal Instruments relative to registered preoperative image data while performing the surgical procedure. Each of the 7D Surgical System instruments, including the FlashLock and Flex Rod, utilizes commercially available passive reflective marker spheres to determine the position and orientation of instruments. Each tracked Instruments requires a unique marker position configuration to enable the tracking system to distinguish the tools from one to the other.
The Software links all system components and displays navigational data to the surgeon. lt provides methods for loading preoperative scans and guides the surgeon through the process of surface model creation, structured light acquisition, registration, registration verification, and navigation.
7. Safety Considerations
This change to add compatibility to the 7D System to include navigational tracking of the FlashLock and Flex Rod 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 FlashLock and Flex Rod 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 ensure the safety and effectiveness of the 7D Surgical System device:
- . Non-Clinical System, Software, and Instrumentation Verification and Validation
