### 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
- Non-Clinical Performance Surgical Simulations Conducted on Phantom Models
- Compliance Conformity Assessments
{6}------------------------------------------------
7D Surgical System
.
Device performance tests were performed to verify the absolute accuracy and repeatability of the accuracy of the device, and the navigation accuracy according to ASTM F2554-10. In addition, Target Registration Error (TRE) and Angular Trajectory Error (ATE) has been used to evaluate the clinical accuracy of the system on phantom models in a clinical simulated environment. TRE and ATE 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<br>the design requirement<br>specifications of 7D Surgical<br>System under test case<br>protocols. | Verification successful, all<br>design requirements have<br>been fulfilled. |
| System Validation | Scope of the test is to validate<br>the Indications For Use and<br>Customer Requirements of the<br>7D Surgical System under<br>simulated use case situations. | Validation successful, all user<br>needs met. |
| Safety regarding risk analysis | Implementation and<br>effectiveness of all risk control<br>requirements specified in the<br>7D Surgical System risk<br>analysis are tested and<br>verified. | Risk Control requirements are<br>effective and mitigate the<br>associated risks to an<br>acceptable level. |
| Product Safety standards | The 7D Surgical System and<br>Instrumentation was tested to<br>the following recognized<br>standards:<br>IEC 60601-1, IEC 60601-1-2,<br>IEC 60601-1-6, IEC 60601-2-41,<br>IEC 60825-1, ISO 10993-1, and<br>ISO 17665-1. | Compliance with recognized<br>standards have been verified<br>in the previous application.<br>Previous test results have not<br>been affected by this change. |
| Non-Clinical Accuracy | System's accuracy is tested<br>using the 7D Surgical System<br>on phantom models following<br>the ASTM F2554-10 Standard<br>Practice for Measurement of<br>Positional Accuracy of<br>Computer Assisted Surgical<br>Systems in addition to Target<br>Registration Error. | All accuracy specifications<br>have been met for the<br>FlashLock and Flex Rod. |
All non-clinical tests successfully passed demonstrating that the subject device performs as safely and effectively as the predicate device and supporting substantial equivalence.
{7}------------------------------------------------
## 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. The clinical safety and effectiveness of Image Guided Surgery Systems are historically accepted for both the predicate and subject device.
### 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 support the safety and effectiveness of the 7D Surgical System compatibility with the FlashLock and Flex Rod. The conclusions drawn from the non-clinical tests demonstrate that the 7D Surgical System performs as safely and effectively as the legally marketed 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.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
