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

    This document describes a 510(k) submission, which relies heavily on non-clinical (bench) testing and comparison to a predicate device, rather than a clinical trial with a "test set" of patients.

    • Sample Size for Test Set: Not applicable in the context of human subjects or "test sets" as you might find in an AI/imaging study. The "test set" in this context refers to the samples used in bench testing (e.g., electrical safety tests, biocompatibility tests), the number of which is not specified in this summary.
    • Data Provenance: Not applicable in terms of country of origin of patient data or retrospective/prospective studies, as no human clinical data is presented here to support the device's safety and effectiveness. The data provenance discussed relates to the manufacturer (Ace Medical Devices Pvt. Ltd., India) and the predicate device manufacturer (Olympus Winter & Ibe GmbH).

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

    Not applicable. This is not a study involving expert review for establishing ground truth from patient data. The "ground truth" for this device's safety and effectiveness is established by its similarity to a device already on the market and its conformance to recognized engineering and safety standards.

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

    Not applicable, as there is no "test set" in the context of human data requiring expert adjudication.

    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 device is an electrosurgical tool, not an AI-assisted diagnostic or therapeutic device that would involve human readers or AI assistance in that way.

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

    Not applicable for the same reasons as above. This is an electrosurgical device, not an algorithm.

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

    The "ground truth" for the substantial equivalence claim is multi-faceted:

    • Predicate Device Performance: The primary ground truth is that the predicate device (Olympus K120418) has a history of safe and effective use in the market.
    • Consensus Standards: Adherence to recognized consensus standards like IEC 60601-1 (electrical safety) and IEC 60601-2-2 (thermal safety), and ISO 14971:2007 (risk management).
    • Bench Testing: Internal design verification testing results (not detailed here) that confirmed the device functions as intended and met acceptance criteria for engineering specifications.
    • Biocompatibility Testing: Results indicating the materials are biocompatible.

    8. The sample size for the training set

    Not applicable. This is not an AI/machine learning study.

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

    Not applicable.
