Intended Use

The drive unit for surgical transmission instruments is indicated for: drilling, milling, sawing, screwing (for positioning) of osteosynthesis screws, implants and plate systems in soft and hard tissue. Including: ENT surgery and Maxillofacial surgery

Device Description

The AMADEO is an electrical drive unit, including motor, attachments and accessories, for surgical transmission attachments which is indicated for: drilling, cutting, sawing, screwing (for placement) of osteosynthesis screws, implants and plates, in soft and hard tissue. The foreseen areas of application will be: ENT (ear, nose, throat) surgery and Maxillofacial surgery. The basic function is the conversion of electrical energy into a mechanical rotary motion. The control unit is used to control the connected motor and the integrated pump. Depending on the treatment, a physiological saline solution is pumped to the treatment site by a displacement pump. A single-use sterile disposable irrigation tubing set is supplied within the scope of delivery and offered as an accessory. The integrated touch display is used to monitor the actual settings and to change, within predetermined limits, the operating parameters. The foot control is used for activation/deactivation of the motor and for changing parameters e.g. program, pump state and motor direction.

AI/ML Overview

This document is a 510(k) Premarket Notification from the FDA for the medical device AMADEO, an electrical drive unit for surgical transmission instruments. It primarily focuses on demonstrating substantial equivalence to a predicate device, the NSK Primado2.

The document does not contain an acceptance criteria table or a study proving the device meets specific performance acceptance criteria in the manner one might expect for a new AI/software device submission. This is because the device, AMADEO, is an electro-mechanical surgical drill system, not an AI or software-only diagnostic device. The evaluation focuses on demonstrating its safety and effectiveness are substantially equivalent to a previously cleared device.

Therefore, many of the requested elements (sample size for test/training sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, type of ground truth) are not applicable or not explicitly detailed in the provided text as they would be for an AI diagnostic device.

However, based on the principle of the 510(k) submission, we can infer the "acceptance criteria" is that the device performs as intended and is as safe and effective as the predicate device. The "study that proves the device meets the acceptance criteria" is the entirety of the non-clinical testing performed to demonstrate substantial equivalence.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

As noted, explicit "acceptance criteria" in the form of performance metrics (like sensitivity, specificity, accuracy) are not provided, as this is an electro-mechanical device, not an AI diagnostic. The "acceptance" is substantial equivalence to the predicate. The performance data and technological characteristics are compared against the predicate device.

2. Sample Size for the Test Set and Data Provenance

Not applicable in the typical sense for an AI/software diagnostic. The "test set" here refers to the physical device and components undergoing bench testing, biocompatibility, electrical safety, and reprocessing validation. The provenance of this would be internal laboratory testing by the manufacturer. No patient data is involved in these types of tests for this device.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

Not applicable for this type of electro-mechanical device submission. Ground truth, in this context, would be established by engineering standards, validated test methods, and industry-accepted protocols for safety and performance (e.g., precise measurements, material analyses).

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in clinical image interpretation or similar diagnostic tasks, which is not relevant here.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No. This type of study is for evaluating human performance with and without AI assistance for diagnostic tasks. The AMADEO is a surgical drill and does not involve AI assistance for human readers/interpreters in a diagnostic context.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

No. This is relevant for AI diagnostic algorithms. The AMADEO is a physical surgical device. Its software controls the device's functions, but it's not a standalone diagnostic algorithm.

7. Type of Ground Truth Used

The "ground truth" for the AMADEO's performance comes from:

  • Engineering Specifications and Standards: The device's design, operational parameters (e.g., motor speed, torque), electrical safety, and electromagnetic compatibility are validated against established engineering specifications and international standards (e.g., IEC 60601-1, IEC 60601-1-2).
  • Biocompatibility Standards: Materials in contact with the patient are tested against ISO 10993 standards.
  • Reprocessing Protocols: The ability to clean and sterilize/disinfect reusable components is validated against FDA guidance and established cleaning protocols.
  • Functional Bench Testing: Verification that the device performs its intended functions (e.g., touchscreen responsiveness, motor control) according to its own design specifications.

8. Sample Size for the Training Set

Not applicable. There is no AI model being trained with a training set for this device.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no training set for an AI model.
