The selection of the appropriate instrument is a matter of surgeon preference.

This document, K060245, is a 510(k) premarket notification for the Harmonic Scalpel Blades and Shears by Ethicon Endo-Surgery, Inc. It seeks to demonstrate substantial equivalence to a predicate device for an expanded set of indications for use.

Based on the provided text, a traditional "acceptance criteria" and "study that proves the device meets the acceptance criteria" in the context of an AI/ML medical device submission (which would typically involve performance metrics like sensitivity, specificity, AUC, etc.) are not applicable.

This device is a surgical instrument (ultrasonic surgical device), not an AI/ML algorithm. The performance data presented is in the form of a clinical literature search, not a study with specific acceptance criteria that an AI algorithm would need to meet. The submission is focused on demonstrating the device's substantial equivalence to a legally marketed predicate device based on its technological characteristics and proposed expanded indications for use.

Therefore, the specific questions related to AI/ML device performance, such as sample size for test sets, expert ground truth, adjudication methods, MRMC studies, standalone performance, and training set details, cannot be answered from the provided text because these elements are not relevant to this type of device submission.

Here's how to interpret the provided information in the context of the device:

1. Table of Acceptance Criteria and Reported Device Performance:

• Acceptance Criteria: For this type of device (ultrasonic surgical instrument), the "acceptance criteria" for regulatory clearance are primarily focused on demonstrating substantial equivalence to a predicate device in terms of safety and effectiveness for its intended use. This typically involves showing that the technological characteristics are the same, and that any new or expanded indications for use are supported by existing clinical evidence or the predicate's established safety profile.
• Reported Device Performance: The primary "performance data" cited is a clinical literature search.

2. Sample size used for the test set and the data provenance: Not applicable. This is not an AI/ML device, so there isn't a "test set" in the computational sense. The "performance data" is a literature review, not a specific data set. The provenance of the literature is not specified beyond being "a clinical literature search."

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. There is no "test set" for an AI/ML algorithm. The "ground truth" for the device's safety and effectiveness for its intended use is established through its technological equivalence to a predicate device and existing clinical literature.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No test set or adjudication process as understood for AI/ML performance assessment.

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 is a surgical instrument, not an AI-assisted diagnostic or therapeutic device for human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a physical surgical instrument, not an algorithm.

7. The type of ground truth used: For this submission, the "ground truth" for demonstrating substantial equivalence is based on the technological characteristics of the device being identical to the predicate, and existing clinical literature supporting the safety and efficacy of the technology (ultrasonic surgical instruments) for the stated indications, particularly the newly expanded ones involving orthopedic structures.

8. The sample size for the training set: Not applicable. This is not an AI/ML device, and there is no "training set."

9. How the ground truth for the training set was established: Not applicable. There is no "training set" or explicit ground truth establishment process in the AI/ML sense for this device.

The provided 510(k) summary for the Ethicon Harmonic Scalpel Blades and Shears does not include information about acceptance criteria or a study proving device performance against such criteria in the way typically expected for a diagnostic AI/ML device.

This 510(k) pertains to a surgical instrument, not a diagnostic AI/ML device. The "Performance Data" section explicitly states: "A clinical literature search was performed to show the use of the devices in plastic surgery." This indicates that the regulatory submission relied on existing clinical evidence for similar devices and the proven safety and effectiveness of the underlying technology, rather than new performance studies with specific statistical endpoints and acceptance criteria as would be required for an AI/ML diagnostic.

Therefore, most of the requested information regarding acceptance criteria, sample sizes, ground truth establishment, expert adjudication, and comparative effectiveness studies are not applicable to this particular device submission.

Here's a breakdown of what can be extracted and what is not applicable based on the provided text:

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

• Not Applicable. The submission does not define specific performance metrics with acceptance criteria (e.g., sensitivity, specificity, AUC) for the device. The "performance" is implicitly related to its intended surgical function (cutting and coagulation with minimal thermal injury and bleeding control), which is demonstrated through established clinical practice and existing literature for the predicate device.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Not Applicable. There was no specific "test set" in the context of a diagnostic performance study. The "Performance Data" section refers to a "clinical literature search." The "sample size" would therefore be the aggregate patient population across the studies identified in that literature, but specific numbers and provenance are not provided as it's not a de novo study.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• Not Applicable. There was no "test set" requiring ground truth established by experts in the context of a diagnostic evaluation.

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

• Not Applicable. There was no test set or adjudication process for diagnostic performance.

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 a surgical 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 device is a surgical instrument, not an algorithm.

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

• Not Applicable. No explicit ground truth was established for a performance study. The "ground truth" for the device's efficacy is based on established surgical outcomes and clinical experience with ultrasonic surgical instruments, as demonstrated by the literature search.

8. The sample size for the training set

• Not Applicable. This device is a physical surgical instrument, not an AI/ML algorithm that requires a training set.

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

• Not Applicable. There is no training set for this device.
