The system accessories are indicated for all cranial and spinal surgical procedures covered by the OTS where anatomical Spinal Surgicur procedures is is where a desired target is close to critical structures.
The above modular product groups consist of a registration device, LED array hardware, and operational software. When coupled with the OTS workstation, the devices allow for preoperative and operative planning of surgical procedures through workstation images.
Here's an analysis of the provided 510(k) summary regarding acceptance criteria and the supporting study:
1. Table of Acceptance Criteria and Reported Device Performance
Based on the provided 510(k) summary, there is no explicit mention of specific acceptance criteria or quantitative device performance metrics (e.g., accuracy, precision) reported in a study. The summary primarily focuses on establishing substantial equivalence to a predicate device.
2. Sample Size Used for the Test Set and Data Provenance
This information is not provided in the 510(k) summary. The document does not describe a performance study with a distinct test set.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications
This information is not provided in the 510(k) summary. As no explicit performance study with a test set is described, there's no mention of ground truth establishment by experts.
4. Adjudication Method for the Test Set
This information is not provided in the 510(k) summary. No adjudication method is mentioned as there's no described test set or evaluation process involving multiple readers.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size
This information is not provided in the 510(k) summary. There is no mention of an MRMC study or any comparison of human readers with and without AI assistance. The device in question is an "Intraoperative Guidance Device" that acts as a "visualization aid to surgery" using LED tracking, not an AI-powered diagnostic tool.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
This information is not provided in the 510(k) summary. The device's function is described as providing "tracking information as an aid to surgery" and correlating instrument/microscope location to patient scan data, which inherently involves human interaction. There isn't a standalone algorithm performance without human involvement described.
7. The Type of Ground Truth Used
This information is not provided in the 510(k) summary. Since no specific performance study is detailed, the type of ground truth used is not mentioned.
8. The Sample Size for the Training Set
This information is not provided in the 510(k) summary. The document does not describe a machine learning model or an algorithm that would require a 'training set.' The device relies on "LED systems" for tracking.
9. How the Ground Truth for the Training Set Was Established
This information is not provided in the 510(k) summary. As there is no mention of a training set, the establishment of its ground truth is also not discussed.
Summary of Device and Regulatory Context:
The provided document is a 510(k) summary for the Radionics Universal Instrument Registration and Microscope Module I accessories. The core of this submission is to demonstrate substantial equivalence to existing predicate devices (Zeiss Surgical Microscope Navigator and Surgical Tool Navigator).
The device is an "Intraoperative Guidance Device" that uses LED array hardware and operational software to:
- Allow surgeons to correlate instrument location to patient scan data.
- Allow surgeons to correlate the focused viewing area of a microscope to patient scan data.
- Guide the microscope to a desired target using workstation images.
The safety and effectiveness are primarily based on the demonstrated technological similarity to predicate devices, which also use LED systems for tracking information as an aid to surgery. No specific performance study with acceptance criteria, test sets, or ground truth is detailed in this 510(k) summary. The FDA's approval letter confirms their determination of substantial equivalence based on the provided information, allowing the device to be marketed under general controls.

This summary was prepared on April 1, 1998.
-
The names of these devices are the Radionics Universal Instrument Registration and Microscope Module I accessories for use with Radionics Optical Tracking System (OTS). The common name is Intraoperative Guidance Device, and its classification name is Stereotaxic instrument (accessory)
-
The above modular product groups are substantially equivalent to the Zeiss Surgical Microscope Navigator (SMN) and Surgical Tool Navigator (STN) modular product groups manufactured by Carl Zeiss, Inc
-
The above modular product groups consist of a registration device, LED array hardware, and operational software. When coupled with the OTS workstation, the devices allow for preoperative and operative planning of surgical procedures through workstation images.
-
The accessories are intended as a visualization aid to surgery. When fitted to a surgical instrument, the LED array hardware allows the surgeon to correlate the instrument location to the patient scan data. Likewise, when attached to a microscope, the LED array hardware allows the surgeon to correlate the focused viewing area to patient scan data, and to guide the microscope to a desired target using workstation images.
-
The technological characteristics are the same or similar to those found with the predicate device where LED systems are used to provide tracking information as an aid to surgery.

Dear Ms. Benati:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
