2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the specific sample sizes used for each test (e.g., number of appliers, number of clips, number of simulated craniotomies). It generally refers to "all required testing" being completed. The tests are bench tests, meaning they were conducted in a laboratory setting, not with human subjects. Thus, data provenance in terms of country of origin or retrospective/prospective medical data is not applicable here as the test data is generated in a controlled environment.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of those Experts
This information is not provided in the document. The tests performed are primarily functional and mechanical, suggesting that the "ground truth" is defined by engineering specifications and performance standards rather than expert clinical consensus.
4. Adjudication Method for the Test Set
This information is not provided. Given the nature of the bench testing (Pass/Fail results against predefined criteria), formal adjudication by multiple parties for each test outcome is unlikely to have been a primary method.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No, an MRMC comparative effectiveness study was not done. The device is a surgical instrument (aneurysm clip applier), and the studies described are bench tests to confirm its mechanical and functional equivalence to predicate devices, not studies involving human readers interpreting imaging data or clinical outcomes. Therefore, an effect size of human readers improving with or without AI assistance is not applicable.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
This question is not applicable to the Aesculap Slim Clip Applier. This device is a manual surgical instrument, not an algorithm or AI-powered system.
7. The Type of Ground Truth Used
The ground truth for the acceptance criteria and testing appears to be based on:
- Engineering Specifications: The required interface and opening width of the aneurysm clip, and the ability to release the clip successfully.
- Functional Performance Standards: The successful performance of the clip applier with the aneurysm clip, and latch functionality.
- Usability Requirements: Ensuring proper identification features, legibility, visualization of the surgical site, and the ability to grasp, hold, and apply the clip.
These are primarily objective, measurable criteria related to the device's design and intended function.
8. The Sample Size for the Training Set
This is not applicable. The Aesculap Slim Clip Applier is a mechanical medical device, not a machine learning or AI algorithm that requires training data.
9. How the Ground Truth for the Training Set was Established
This is not applicable, as there is no training set for a mechanical device.
