The VSII System is intended for viewing internal surgical sites during anterior and posterior spinal procedures, such as nucleotomy, discectomy, and foraminotomy, as well as for viewing internal surgical sites during general surgical procedures and for use in visualization of ventricles and structures within the brain during neurological surgical procedures.

Visionsense Stereoscopic Vision System (VSn) consists of a proprietary CCD camera, embedded in the distal end of a rigid metal arthroscope. An array of miniature lenses - the Lenticular Arrav (LA) - built onto the CCD surface during the wafer fabrication process, captures the image from slightly different angles, thus mimicking the natural human "stereo vision" obtained when the eyes simultaneously pick up two different images of the same object (right and left). The captured image is subsequently transmitted to a PC workstation, processed and presented on a stereoscopic display panel. Images are recorded and may be later downloaded for further analysis.

The provided text is a 510(k) summary for the Visionsense Stereoscopic Vision System (VSn). It describes the device, its intended use, and substantial equivalence to predicate devices. However, the document does not contain explicit acceptance criteria or detailed study results demonstrating performance against such criteria.

The section titled "Performance" states: "No performance standards or special controls have been developed under Section 514 of the Federal Food, Drug, and Cosmetic Act ("FDC Act") for arthroscopes. However, the VSn System and its components comply with international standards for electrical safety, electromagnetic compatibility, and biocompatibility."

This indicates that the submission primarily relies on demonstrating substantial equivalence to predicate devices based on technological characteristics and intended use, rather than presenting a performance study with defined acceptance criteria.

Therefore, many of the requested details cannot be extracted from the provided document.

The VSn system is intended for viewing internal surgical sites during general surgical procedures and for use in visualization of ventricles and structures within the brain during neurological surgical procedures.

Visionsense Stereoscopic Vision System (VSu) consists of a proprietary CCD camera, embedded in the distal end of a rigid metal endoscope. An array of miniature lenses - the Lenticular Array (LA) - built onto the CCD surface during the wafer fabrication process, captures the image from slightly different angles, thus mimicking the natural human 'Stereo vision' obtained when the cycs simultaneously pick up two different images of the same object (right and left). The captured image is subsequently transmitted to a PC workstation, processed and presented on a stereoscopic display panel. Images are recorded and may be later downloaded for further analysis.

The provided text does not contain information about acceptance criteria or a study that proves the device meets specific acceptance criteria. The document is a 510(k) summary for the VISIONSENSE Stereoscopic Vision System (VSII), primarily focusing on demonstrating substantial equivalence to a predicate device for an expanded indication (neurosurgical procedures).

The key information available covers:

• Device Information: Trade name, common name, classification, review panel, product code, device class.
• Predicate Devices: K073279 (VSII General Surgery) and K964281 (Aesculap Angled Neuroendoscopes).
• Intended Use/Indications for Use: Viewing internal surgical sites during general surgical procedures and visualization of ventricles and structures within the brain during neurological surgical procedures.
• Technological Characteristics/Principles of Operation: Proprietary CCD camera, Lenticular Array for stereoscopic vision, PC workstation processing, stereoscopic display.
• Substantial Equivalence: Claimed based on technological similarity to the previously cleared general surgery VSII and to other neurosurgical endoscopic devices (Aesculap).

The document explicitly states: "No performance standards or special controls have been developed under Section 514 of the Federal Food, Drug, and Cosmetic Act ("FDC Act") for endoscopes. However, the VSII system and its components comply with international standards for electrical safety, electromagnetic compatibility, and biocompatibility."

This indicates that specific performance acceptance criteria for the expanded neurosurgical indication were not established or assessed in the traditional sense of a clinical performance study with predefined metrics. The submission relies on substantial equivalence to existing devices and compliance with general safety and electromagnetic standards rather than a study demonstrating meeting specific clinical performance acceptance criteria.

Therefore, I cannot populate the table or provide information for points 2 through 9 as requested, as these details are not present in the provided text.

The VSII system is intended for viewing internal surgical sites during general endoscopic and laparoscopic surgical procedures.

Not Found

The provided text is a 510(k) summary for the Visionsense Ltd.'s VSII System, a stereoscopic vision system for general endoscopic and laparoscopic surgical procedures. It primarily focuses on demonstrating substantial equivalence to a predicate device (ELRAN 01 Stereoscopic Laparoscope) rather than detailing performance studies and acceptance criteria for entirely new device claims.

Therefore, much of the requested information regarding acceptance criteria, study details, sample sizes, ground truth establishment, and expert involvement is not present in the provided document. The 510(k) process for substantial equivalence often relies on demonstrating that the new device performs "as safe and effective" as the predicate, rather than establishing entirely new performance benchmarks through extensive studies typically associated with novel or high-risk devices.

Here's what can be extracted and what is missing:

1. A table of acceptance criteria and the reported device performance

Missing: Specific quantitative acceptance criteria (e.g., minimum resolution, field of view, illumination levels, specific accuracy metrics for stereoscopy) and the quantitative results of the VSII System against these criteria. The document states "Performance data demonstrates," but does not provide the specifics of this data or the defined acceptance thresholds.

2. Sample size used for the test set and the data provenance

Missing: The document does not mention any specific "test set" in the context of device performance evaluation, nor does it provide details on sample size or data provenance (country of origin, retrospective/prospective). The assessment appears to be based on a comparison to the predicate device's established performance rather than a new standalone clinical study.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Missing: This information is not provided because there is no mention of a "test set" and corresponding ground truth establishment by experts for the VSII system in this summary.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Missing: Not applicable, as no test set or expert adjudication is described.

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

Missing: This is not applicable to the VSII System, which is a stereoscopic vision system, not an AI-assisted diagnostic tool for human readers. No MRMC study is mentioned.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The document does not describe a "standalone" algorithmic performance study in the context of AI. The VSII system is a viewing system, not an algorithm. The "performance data" mentioned is likely related to engineering tests and optical characteristics to ensure similar performance to the predicate device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Missing: No "ground truth" in the clinical AI sense is mentioned, as there are no diagnostic claims or classifications being made by the device itself that would require clinical ground truth.

8. The sample size for the training set

Missing: Not applicable, as this is a hardware vision system, not an AI model that undergoes "training."

9. How the ground truth for the training set was established

Missing: Not applicable for the same reason as above.
