The piezoelectric surgical system is indicated for: osteotomies, osteoplasties, drilling and shaping of hard tissue. Including:

• Otolaryngology,
• Maxillofacial surgery,
• hand- & foot-surgery and
• plastic & reconstructive surgery.

The new device, the "Piezomed Pro", is an ultrasonic surgical modular system which has to be connected to W&H's AMADEO device (K213221). The new device is an ultrasonic surgical system whose basic function is the conversion of electrical energy into mechanical vibration.

In addition, a physiological saline solution is pumped to the treatment site with a displacement pump, depending on the treatment.

Using a control unit with electronics, the user can change several operating parameters within predefined limits:

• oscillation amplitude, 5 to 100% in steps of 5 (100 % corresponds to max. power)
• coolant flow rate via pump speed control; 5 to 100% in steps of 5 (100% corresponds to max. water quantity)

The device is activated or deactivated via a foot control.

The provided FDA 510(k) clearance letter for the Piezomed Pro describes a surgical device (an ultrasonic surgical modular system), not a diagnostic AI device. Therefore, the information typically requested regarding acceptance criteria and performance studies for an AI/ML-enabled diagnostic device (such as accuracy, sensitivity, specificity, sample sizes, ground truth establishment, expert adjudication, MRMC studies) is not present in this document.

This document focuses on proving substantial equivalence for a physical medical device based on:

• Intended Use/Indications for Use: The Piezomed Pro is indicated for osteotomies, osteoplasties, drilling, and shaping of hard tissue in various surgical specialties. This is shown to be identical to the predicate device.
• Technological Characteristics: The device's operating principle (conversion of electrical energy into mechanical vibration), frequency, operating mode, electrical classification, and components are compared to predicate and reference devices, demonstrating similarity.
• Performance Data: This section details non-clinical testing for biocompatibility, electromagnetic compatibility, electrical safety, reprocessing validation, and general performance/functional testing (e.g., life-time, falling, vibration tests).
• Software and Cybersecurity: Compliance with relevant standards and guidance documents for software development and cybersecurity is stated.

Therefore, based on the provided text, it's not possible to extract the information required for an AI/ML diagnostic device performance study. The questions provided in the prompt are geared towards evaluating the performance of an AI algorithm against a ground truth, which is not the subject of this 510(k) submission for the Piezomed Pro.

If this were an AI/ML diagnostic device, the "Performance Data" section would describe clinical study results, including metrics like sensitivity, specificity, AUC, and details about the test set, ground truth, and reader studies. Since it's a surgical tool, the performance data relates to its physical and functional safety and effectiveness, rather than diagnostic accuracy.
