Indications for Use
The Terumo SurGuard®3 Safety Hypodermic Needle is intended for use in the aspiration and injection of fluids for medical purposes. The Terumo Safety Hypodermic Needle is compatible for use with standard luer lock syringes. Additionally, after withdrawal of the needle from the body, the attached needle safety sheath can be manually activated to cover the needle immediately after use to minimize risk of accidental needlestick.
Device Story
The Terumo SurGuard®3 Safety Hypodermic Needle is a manual hypodermic needle featuring an integrated, hinged safety sheath. It is used by clinicians to aspirate or inject fluids. After withdrawal from the patient, the user manually activates the sheath—using a finger, thumb, or firm surface—to cover the needle cannula. The sheath includes tactile guides (circular dent and ramp) and stoppers to ensure proper finger positioning and prevent contact with the needle during activation. The device locks the needle inside a tooth-cannula mechanism to minimize accidental needlestick injuries. It is supplied sterile and is intended for single use.
Clinical Evidence
No clinical data. Bench testing only, including performance testing per ISO 7864 (conical fitting, bond strength) and ISO 23908 (needle access to sharp in safe mode), as well as internal testing for sheath activation/deactivation, needle penetration, and simulated use.
Indicated for aspiration and injection of fluids for medical purposes in patients requiring hypodermic needle use. Compatible with standard luer lock syringes. No specific contraindications listed.
Regulatory Classification
Identification

## E. REASON FOR 510(k) SUBMISSION
This premarket notification (Special 510(k)) is being submitted for the Terumo SurGuard 3 Safety Hypodermic Needle, manufactured by Terumo (Philippines) Corporation, for the following modifications to the current device: new needle length (19mm), new gauge sizes (18, 19, 20, and 22) for 13 and 16mm needle lengths, cleared under K122249, and a modified safety sheath design for all new gauge and needle length combinations.
## F. DEVICE DESCRIPTION (807.92(a)(4))
#### Principle of Operation Technology
The Terumo SurGuard®3 Safety Hypodermic Needle is operated manually or by manual process.
{5}------------------------------------------------
## Design/Construction
The Terumo SurGuard®3 Safety Hypodermic Needle [hereinafter referred to as "SurGuard 3 (Short Sheath 2)"] consists of a hypodermic needle with a hinged safety sheath attached to the connector hub which can be attached to either a luer slip or luer lock syringe. This device features a hinged safety sheath attached to the needle hub. The safety sheath contains two locking mechanisms, the tooth-cannula and sheathcollar which are simultaneously activated when manually pressed over the needle immediately after use and just prior to disposal to minimize the possibility of sharps injury. The safety sheath is activated with a one-handed operation, using the finger, thumb, or surface activation.
The safety sheath has a finger guide area consisting of a circular dent (for thumb activation; see Figure A) and ramp (for finger activation; see Figure B) which provides tactile confirmation that the user's finger is in the appropriate position for performing the activation. The ramp has steps to provide strong grasp when activating the sheath. There are two stoppers which is located at the end of the circular dent and ramp which prevent the user's finger from going towards the cannula during activation. Another method of activation is by manually pressing the safety sheath over the needle using a firm surface.

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.

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
