The Stryker Videoscope is a video endoscope indicated for use in endoscopy and endoscopic surgery within the thoracic and abdominal cavities, including female reproductive organs.
The Stryker Videoscope is a video endoscope intended to illuminate and allow observation of body cavities relating to general endoscopic, laparoscopic and gynecological surgeries. Traditionally, surgeons would need multiple scopes with varying direction of view angles (such as 0°, 30°, and 45°) to have a wide range of view. The Stryker Videoscope can provide varying angles all in one scope through a distal articulating section that changes the direction of view between 0° and 110° (±10°) from the axis of the scope. The Videoscope will have a working length of 330mm, with an outer diameter of 10mm.
The provided document is a 510(k) pre-market notification for the Stryker Videoscope. It focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study proving the device meets specific acceptance criteria based on clinical performance metrics. Therefore, many of the requested elements for a detailed study report are not present in this document.
Here's an analysis based on the information available:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly present a table of acceptance criteria with corresponding performance results in the format typically seen for a new device's clinical performance study (e.g., sensitivity, specificity, accuracy). Instead, it focuses on demonstrating equivalence to a predicate device by comparing characteristics and performance specifications.
The closest to "acceptance criteria" are the standards the device conforms to and the comparison to the predicate device.
| Characteristic / Standard | Acceptance Criteria (Implied by Predicate Equivalence & Standards) | Reported Device Performance (Stryker Videoscope) |
|---|---|---|
| Intended Use | Same as predicate (endoscopy and endoscopic surgery within the thoracic and abdominal cavities, including female reproductive organs). | The Stryker Videoscope is a video endoscope indicated for use in endoscopy and endoscopic surgery within the thoracic and abdominal cavities, including female reproductive organs. (Same) |
| Field of View (FOV) | Not explicitly stated as "acceptance criteria," but compared to predicate's 90°. | 75° +/- 5° (Different, but deemed equivalent) |
| Direction of View | Same as predicate (0° Forward Viewing). | 0° Forward Viewing (Same) |
| Outer Diameter | Not explicitly stated as "acceptance criteria," but compared to predicate's 10.5mm. | 10mm (Different, but deemed equivalent) |
| Bending Section Angulations (UP/DOWN/LEFT/RIGHT) | Not explicitly stated as "acceptance criteria," but compared to predicate's 100°/100°/60°/60°. | 110°/110°/110°/110°, ± 10 (Different, but deemed equivalent, allowing more flexibility) |
| Working Length | Same as predicate (330mm). | 330mm (Same) |
| Inner Working Channel | Not explicitly stated as "acceptance criteria," but compared to predicate's "Provided." | None (Different, but deemed equivalent as its function (insufflation/irrigation) is not indicated for the Stryker Videoscope) |
| Biocompatibility | Conformance to ISO 10993-1:2003 and FDA Blue Book Memorandum #G95-1. | All patient contacting materials are validated for biocompatibility in accordance with the requirements. |
| Sterilization | Able to be sterilized to a SAL = 10⁻⁶ via Sterrad and ETO. | Sterility Assurance Validation testing will be conducted to ensure it is able to be sterilized to a SAL = 10⁻⁶. ETO Residuals will be tested according to ISO10993-7. |
| Mechanical Reliability | Optimal performance and reliability (implied). | A mechanical reliability test will be conducted to ensure optimal performance and reliability. |
2. Sample size used for the test set and the data provenance
The document does not describe a clinical "test set" in the context of diagnostic performance (e.g., images for readers to interpret). The "testing" mentioned pertains to engineering verification and validation of physical device characteristics (e.g., mechanical reliability, biocompatibility, sterilization). Therefore, sample sizes for a clinical test set and data provenance (country, retrospective/prospective) are not applicable or provided in this document.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
As there is no clinical "test set" for performance evaluation against a ground truth in this document, this information is not available.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable as there is no clinical "test set" for performance evaluation.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This document describes a videoscope, which is a viewing instrument, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This document describes a videoscope, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. Ground truth for clinical performance comparison is not relevant to this 510(k) submission for a videoscope. The "ground truth" for the device's characteristics is based on established engineering and manufacturing specifications and testing standards.
8. The sample size for the training set
Not applicable. This document describes a videoscope, not a machine learning model that requires a training set.
9. How the ground truth for the training set was established
Not applicable. This document describes a videoscope, not a machine learning model that requires a training set.
Summary of the Study and Device Approval:
The document describes a 510(k) pre-market notification for the Stryker Videoscope. The "study" presented here is a demonstration of substantial equivalence to a predicate device (Olympus Laparo-Thoraco Videoscope XLTF-VAW, K053382), rather than a clinical performance study with defined acceptance criteria and statistical analysis.
The document claims that the Stryker Videoscope meets acceptance criteria implicitly by:
- Having the same intended use as the predicate device.
- Conforming to various voluntary safety and performance standards (e.g., ISO 10993 for biocompatibility, IEC 60601-1 for electrical safety, ISO 8600 for endoscope requirements, EN 550 for sterilization).
- Undergoing (or committing to undergo) verification and validation testing for mechanical reliability, biocompatibility, and sterilization, ensuring it meets these relevant safety and performance standards.
- Minor technological differences (such as outer diameter, FOV, bending angulations, and absence of an inner working channel) are argued not to raise new questions regarding safety or effectiveness and are explained with rationale (e.g., smaller FOV allows better image quality, increased articulation offers more flexibility).
The FDA's decision to clear the device K082451 confirms that based on the presented information, the device is considered substantially equivalent to the predicate device and therefore "as safe and effective."

Safety and Performance Testing 6.3.
Mechanics/Articulating mechanism and controls: The Stryker 6.3.1.
Videoscope has an articulating distal tip to allow the user to view the surgical area. The articulating section is made up of several links that are attached to four guide wires. These guide wires run from the distal tip up into the handle where the control levers are located. The external control handles, when moved, drive the internal articulating mechanism to push and pull the bending section in four directions and operates similarly to a pulley system. A mechanical reliability test will be conducted to ensure optimal performance and reliability.
Biocompatibility 6.3.2.
All patient contacting materials are validated for biocompatibility in accordance with the requirements of ISO 10993-1:2003 and FDA Blue Book Memorandum #G95-1. Additionally, patient-contacting and usercontacting materials do not contain natural rubber or latex. Refer to Section 6.2.2 or Table 3 for patient contacting materials.
- Sterilization: The Stryker Videoscope will be a reusable device. As 6.3.3. such, it will undergo Sterility Assurance Validation testing to ensure it is able to be sterilized to a SAL =10 - . The two methods of sterilization that will be available to the users are Sterrad and ETO. ETO Residuals will be tested according to ISO10993-7.
SUBSTANTIAL ROUTHAL BROOM COMPARISON 7.0
The Stryker Videoscope described in this 510(k) notification is substantially equivalent to the currently marketed predicate device; the Olympus Laparo-Thoraco Videoscope XLTF-VAW. The fundamental technology and intended use is similar for both the Stryker Videoscope and Olympus Laparo Thoraco Videscope XLTF-VAW. In the following sections, the proposed device's characteristics are compared with the predicate device and the differences with respect to their impact on safety and effectiveness are discussed.

DISCUSSION OF DIFFERENCES 7.1.
- Outer Diameter: The diameter of the Stryker Videoscope is .5mm 7.1.1. smaller than the Olympus Laparo Thoraco Videoscope XLTF-VAW. Laparoscopes generally come in 5mm and 10 - 11mm. Both the Stryker and Olympus Videoscopes fall within the 10-11mm range. The slight difference in diameter will not significantly affect the optical image or the incision created when used in surgery.
- Bending Section Angulations/FOV: The Stryker Videoscope will have 7.1.2. a bending articulation of 110° (±10°) up, down, left and right with a field of view (FOV) of 75 degrees. The Olympus Laparo Thoraco Videoscope XLTF-VAW has a bending articulation of 100° up and down, 60° left and right with a FOV of 90 degrees. The bending section angulations allow the user to vary the direction of view; while the FOV dictates how much the user sees within the image. In general, as the FOV gets bigger, the image quality tends to get reduced. By keeping a smaller FOV, the Stryker Videoscope may maintain a greater degree of image quality. The device will have the ability to articulate at 110° all around, so that although the FOV is smaller than the Olympus Videoscope, the direction of view can be varied 50° more to the left and right. The surgeon will have the convenience of articulating 110° (±10°) all around, allowing more flexibility through articulation while minimizing the movement of the scope handle.
- Inner Working Channel: An inner working channel will not be 7.1.3. provided with the Stryker Videoscope. The predicate device uses the inner working channel to perform insufflation and irrigation, both of which are not indicated in the Stryker Videoscope.
8.0 CONCLUSION
As demonstrated through comparisons between the predicate device Olympus Laparo Thoraco Videoscope XLTF-VAW and the proposed, the Stryker Videoscope, no significant differences exist in the indications for use, surgical procedures, constructions, performance specifications and labeling of these devices. As there are no significant differences, there are no new questions raised regarding safety and effectiveness. Therefore, the Stryker Videoscope is considered, in terms of safety and effectiveness, substantially equivalent to the currently marketed device.
