The Illuminated Retractor is a manual surgical instrument with an integrated light source that will be sold separately as a single use only device. This can be used with the Knifelight to facilitate ligament or tissue division, or it can be used by itself to retract soft tissue.
The Stryker Illuminated Retractor is a manual surgical instrument with an integrated light source that will be sold separately as a single use only device. This can be used with the Knifelight to facilitate ligament or tissue division, or it can be used by itself to retract soft tissue.
The provided document, K981717, is a Premarket Notification 510(k) Summary for the Stryker Illuminated Retractor. This document primarily focuses on establishing substantial equivalence to previously marketed devices and does not contain detailed information about acceptance criteria, specific device performance studies, or quantitative results from such studies. Therefore, it is not possible to complete the requested table or answer most of the questions based solely on the provided text.
Here's an explanation of why and what information is missing:
Explanation Regarding Missing Information:
The document explicitly states: "The Stryker Illuminated Retractor is equivalent to existing marketed products by companies such as Ruggles and Stryker. Intended use, function, and safety risks are all substantially equivalent." and "The Stryker Illuminated Retractor does not raise any new safety and efficacy concerns when compared to similar legally marketed devices. Therefore, the Stryker Illuminated Retractor is substantially equivalent to these existing devices."
This type of 510(k) submission generally relies on demonstrating that a new device is as safe and effective as a legally marketed predicate device, rather than requiring extensive new clinical or performance studies with specific outcome metrics and acceptance criteria. The FDA's letter confirms substantial equivalence but doesn't detail performance metrics.
What We Can Infer (and what we cannot):
- Acceptance Criteria & Device Performance: The document does not define specific acceptance criteria (e.g., minimum brightness, durability cycles, precise surgical outcomes) or report quantitative performance data. The "performance" assessment is based on a qualitative claim of equivalence.
- Study Details: There's no mention of a formal study with a defined test set, training set, ground truth, expert involvement, or statistical analysis.
- Sample Size: No sample sizes are provided for any testing, as no specific performance testing is described beyond the general equivalence claim.
- Data Provenance: Not applicable as no specific data or studies are mentioned.
- Experts: No experts are mentioned as being involved in establishing ground truth or evaluating the device's performance in a study context.
- Adjudication Method: Not applicable.
- MRMC Comparative Effectiveness Study: Not mentioned, and highly unlikely for a device of this nature in a 510(k) submission focused on substantial equivalence.
- Standalone Performance: Not mentioned.
- Ground Truth Type: Not applicable, as performance studies establishing ground truth are not described.
- Training Set Sample Size & Ground Truth: Not applicable, as no machine learning or AI component is mentioned, and therefore no training set.
Summary of Information from the Provided Text:
- Device Name: Stryker Illuminated Retractor
- Classification Name: Surgical Instrument Illuminated Retractor, Surgical Instrument Light
- Common/Usual Name: Illuminated Retractor
- Proprietary Name: Stryker Illuminated Retractor
- Intended Use: A manual surgical instrument with an integrated light source, sold separately as a single-use-only device. Can be used with the Knifelight to facilitate ligament or tissue division, or by itself to retract soft tissue.
- Regulatory Class: Class II
- Basis for Marketing: Substantial Equivalence to existing marketed products (Ruggles and Stryker).
- Safety and Effectiveness Claim: "Does not raise any new safety and efficacy concerns when compared to similar legally marketed devices."
Conclusion:
Based strictly on the provided text, it's impossible to fill out the table or answer the specific questions about acceptance criteria and detailed study information, as the document is a 510(k) summary focused on establishing substantial equivalence for a medical instrument, not a report on a detailed performance study with quantitative results.

Re: K981717 Trade Name: Stryker Illuminated Retractor Regulatory Class: II Product Code: FTD Dated: May 12,1998 Received: May 15, 1998
Dear Ms. Petty:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing mayor regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
