The Mazor X is indicated for precise positioning of surgical instruments or spinal implants during general spinal surgery. It may be used in open or minimally invasive or percutaneous procedures.
Mazor X 3D imaging capabilities provide a processing and conversion of 2D fluoroscopic projections from standard C Arms into volumetric 3D image. It is intended to be used whenever the clinician and/or patient benefits from generated 3D imaging of high contrast objects.
The Mazor X navigation tracks the position of instruments, during spinal surgery, in relation to the surgical anatomy and identifies this position on diagnostic or intraoperative images of a patient.
The Mazor X system combines robotic trajectory guidance with navigated surgical instruments (either guided or free hand navigation) to enable the surgeon to precisely position surgical instruments and/or implants according to predefined planning. With the imaging capabilities of the system, the user can also visualize the implants on the patients CT. Same as the predicate device the modified Mazor X consists of a workstation with dedicated software, the surgical system, navigation camera, accessories, instruments and disposable kits. The modified Mazor X, the subject of this 510(k) application, introduces software and hardware modifications to the Mazor X System cleared in 510(k) K203005.
The provided text is a 510(k) Summary for the Mazor X System (Mazor X Stealth Edition), detailing its substantial equivalence to a predicate device (K203005). The document focuses on comparing technological characteristics and asserting that modifications do not raise new safety or effectiveness concerns.
However, it does not contain a detailed study proving the device meets specific acceptance criteria in the manner requested by the prompt. This document is a regulatory submission demonstrating substantial equivalence, not a clinical study report with performance metrics like accuracy, sensitivity, or specificity against defined ground truth.
Therefore, many parts of your request for acceptance criteria and study details cannot be fulfilled from the provided text.
Here's what can be extracted and what is missing:
Device: Mazor X System (Mazor X Stealth Edition)
1. Table of Acceptance Criteria and Reported Device Performance
The document describes performance in terms of equivalence to a predicate device rather than specific acceptance criteria for a new study. The closest to "acceptance criteria" related to performance are the accuracy metrics established by the predicate device.
| Characteristic | Acceptance Criteria (from predicate) | Reported Device Performance (Modified Mazor X) |
|---|---|---|

§ 882.4560 Stereotaxic instrument.
(a)
Identification. A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.(b)
Classification. Class II (performance standards).
