ExcelsiusGPS® is intended for use as an aid for precisely locating anatomical structures and for the spatial positioning and orientation of an instrument holder or guide to be used by surgeons for navigating and/or guiding compatible surgical instruments in open or percutaneous provided that the required fiducial markers and rigid patient anatomy can be identified on CT scans or fluoroscopy. The system is indicated for the placement of spinal and orthopedic bone screws.
ExcelsiusHub™ is intended for use as an aid for precisely locating anatomical structures to be used by surgeons for navigating compatible surgical instruments in open or percutaneous procedures provided that the required fiducial markers and rigid patient anatomy can be identified on CT scans or fluoroscopy. The system is indicated for the placement of spinal and orthopedic bone screws.
Subject ExcelsiusGPS® instruments consist of array sleeve adapters and surgical instruments, including drivers, drills, taps, and probes, that may be used manually or navigated with the use of ExcelsiusGPS® or ExcelsiusHub™. The surgical instruments are used to prepare the implant site or implant the device. Instruments are non-sterile and reusable.
The provided document is a 510(k) premarket notification for the ExcelsiusGPS® Instruments, specifically for additional instruments to be used with the existing ExcelsiusGPS® or ExcelsiusHub™ systems for navigating and/or guiding compatible surgical instruments for the placement of spinal and orthopedic bone screws.
There is no mention of an AI/ML component in this document. The device is a set of surgical instruments (array sleeve adapters, drivers, drills, taps, probes) that can be used manually or navigated with the existing ExcelsiusGPS® or ExcelsiusHub™ systems. Therefore, the questions related to AI/ML device performance, such as acceptance criteria for AI algorithms, test set sample sizes, expert ground truth, MRMC studies, or standalone algorithm performance, are not applicable to this submission.
The "Performance Testing" section describes verification tests including "instrument integration and comparison to the predicate devices" to confirm the instruments meet performance requirements. However, specific acceptance criteria and the results of these tests are not detailed in this summary. Biocompatibility was also confirmed by using materials consistent with predicate devices.
Therefore, I cannot provide the requested information regarding AI/ML acceptance criteria and study details because the document does not indicate that the ExcelsiusGPS® Instruments or its associated systems utilize AI/ML technology subject to such evaluation.
