The SURGIVISIO Device is a medical device that provides 2D/3D medical imaging and stereotaxic guidance. The subject device offers two stereotaxic quidance features: freehand navigation and robotic guidance.

The freehand navigation feature is based on the standard and established technique of navigation systems utilizing optical position determination technology. Like currently marketed optical tracking navigation systems, the operating principle of the freehand navigation feature is based upon the use of a stereoscopic camera emitting infrared light which can determine a 3D position of reflective marker spheres. This allows for real-time tracking of the marker spheres. The system components include a stereoscopic camera (SURGIVISIO Camera Pole), a computer platform with monitors (SURGIVISIO Station) and navigation software (3D Spine Universal Workflow software application) and instruments equipped with marker spheres to enable an exact localization in space.

The robotic quidance feature utilizes the same principle of optical position determination technology. The system components include a stereoscopic camera (SURGIVISIO Camera Pole), a computer platform with monitors (SURGIVISIO Station) and a navigation software (3D Spine Robotic Workflow software application), a robotic arm (CoBot), and instruments equipped with marker spheres to enable an exact localization in space.

The provided text describes a 510(k) premarket notification for the SURGIVISIO Device, focusing on a design modification to the Spine CoBot instruments used with its robotic guidance feature.

Here's an analysis of the provided text, focusing on the acceptance criteria and study information for the SURGIVISIO Device:

Note: The provided text is an FDA 510(k) summary, which often focuses on demonstrating substantial equivalence to predicate devices rather than deeply detailing the design and execution of individual performance studies, especially clinical ones. As such, some of the requested information (like specific sample sizes for test/training sets, detailed expert qualifications, adjudication methods, and MRMC study details) is not explicitly present or fully elaborated in this type of document. I will extract what is directly stated and highlight where information is absent.

Acceptance Criteria and Device Performance

The acceptance criteria for the SURGIVISIO Device are implicitly defined by its comparison to the predicate devices, specifically regarding "System accuracy" and "Device accuracy." The device claims to meet these criteria.

The SURGIVISIO device is intended to be used during surgical procedures in which the physician would benefit from the visualization of 2D medical imaging and/or intraoperatively generated 3D medical structures or objects with high x-ray attenuation such as bony anatomy or metallic objects. Such procedures during which the spine, pelvis or articulation structures are visualized.

The SURGIVISIO Device is a mobile x-ray system which provides 2D imaging and allows the generation of intraoperative 3D information of high contrast objects and anatomical structures. The system consists of two mobile interconnected units: a mobile C-arm and a mobile viewing Workstation. These units are moved manually and are interconnected by a single cable that provides power and transfer of data and controls. The mobile C-Arm comprises a high voltage generator, foot switches for radiation release, laser target devices, electronics cabinet, collision avoidance system, and a C-shaped structure mounting the X-ray tube assembly and the flat X-ray detector on distal end of the 'C'. The mobile viewing workstation comprises a computer, an image detector process unit, the main power supply, radiation indicator, dual viewing monitors and a user interface for patient management and image handling.

The system integrates a Computer Aided Surgery (CAS) feature that supports instruments positioning during surgical procedures.

The SPX1 Instruments are a set of dedicated accessories intended to be used in conjunction with the SURGIVISIO Device in order to enable stereotaxic guidance. More specifically, and when used with the 3D imaging, they support the registration of patient anatomy with the 3D reconstructed image. the Submissions K202547/ K220627 consider SPX1 instruments set with the standard 3D Imaging Set SPX1 accessory.

This submission aims at clearing a new imaging set accessory possibility: the 3D Offset Imaging Set SPX1 accessory, containing same patient reference and wedges as 3D imaging Set SPX1 accessory already 510(k) cleared, and an offset phantom (new instrument). The principle of use of the Offset Phantom SPX1 is identical to the already 510(k) cleared Phantom SPX1 (belonging to 3D Imaging set). However, the Offset Phantom SPX1 additional value is to offset the imaging area that will be navigated during surgery by 10 cm from the standard configuration. The 3D Imaging Set SPX1 accessory will be considered as the predicate for the 3D Offset Imaging Set SPX1 accessory.

I am sorry, but I cannot fulfill your request to describe the acceptance criteria and study proving device performance based on the provided text. The document is primarily a 510(k) summary for a medical device (SURGIVISIO Device) and focuses on demonstrating substantial equivalence to a predicate device rather than presenting detailed acceptance criteria and the comprehensive study results that prove the device meets those criteria.

Here's why I cannot extract the requested information:

• Lack of Specific Acceptance Criteria: The text avers to "standards, acceptance criteria and results" in the "Performance Data" section but explicitly states that those details can be found in a "Design Control Activities Summary," which is not included in the provided document. Therefore, the specific numerical or qualitative acceptance criteria for the device's performance are missing.
• Focus on Substantial Equivalence, Not De Novo Performance Study: The document's core purpose is to show that a new accessory (3D Offset Imaging Set SPX1) for an existing device (SURGIVISIO Device) is substantially equivalent to a previously cleared version. It states, "No clinical tests were conducted to demonstrate substantial equivalence." The non-clinical tests mentioned are primarily design verification, accuracy verification, software verification, and packaging validation, all aimed at confirming the new accessory functions similarly and safely to the predicate, not necessarily to establish de novo performance against a set of independent acceptance criteria for the entire system from scratch.
• Missing Study Details: While some non-clinical tests are listed (design verification, accuracy verification, software verification, packaging validation), the text does not provide the methodology, sample sizes, data provenance, ground truth establishment, expert qualifications, adjudication methods, or direct performance metrics in the way you've requested for a detailed study. It merely states that these tests "have been performed as intended" or "have been conducted as intended."

In summary, the provided FDA document is a regulatory submission for substantial equivalence, not a detailed scientific study report containing the specifics of acceptance criteria and the comprehensive data proving the device meets them. The crucial information you've asked for (e.g., actual performance values against acceptance criteria, detailed methodologies, sample sizes for test sets, ground truth establishment details, MRMC study results) is explicitly stated to be elsewhere ("Design Control Activities Summary") or is simply not part of this type of regulatory summary.

The SURGIVISIO medical device is intended to be used during surgical procedures in which the physician would benefit from the visualization of 2D medical imaging and/or intraoperatively generated 3D medical imaging of anatomical structures or objects with high x-ray attenuation such as bony anatomy or metallic objects. Such procedures include procedures during which the spine, pelvis or articulation structures are visualized.

The SURGIVISIO Device is a mobile x-ray system which provides 2D imaging and allows the generation of intraoperative 3D information of high contrast objects and anatomical structures. The system consists of two mobile interconnected units: a mobile C-arm and a mobile viewing Workstation. These units are moved manually and are interconnected by a single cable that provides power and transfer of data and controls. The mobile C-Arm comprises a high voltage generator, foot switches for radiation release, laser target devices, electronics cabinet, collision avoidance system, and a C-shaped structure mounting the X-ray tube assembly and the flat X-ray detector on distal end of the 'C'. The mobile viewing workstation comprises a computer, an image detector process unit, the main power supply, radiation indicator, dual viewing monitors and a user interface for patient management and image handling. The system integrates a Computer Aided Surgery (CAS) feature that supports instruments positioning during surgical procedures.

The provided text describes the SURGIVISIO Device, which is a mobile interventional fluoroscopic x-ray system, and states that it relies on the substantial equivalence to a previously cleared predicate device (SURGIVISIO system K202547). The primary change in the current submission is a software version update from 1.5.1 to 1.8.1.

While the document mentions "Software Verification testing verifying the software requirements perform as intended," it does not explicitly state specific acceptance criteria or provide a detailed study report that proves the device meets particular acceptance criteria beyond the software verification. The core of the argument for acceptance is substantial equivalence to the predicate device, implying that since the software update maintains the same intended use and performance, it meets the inherent criteria of the predicate.

Given this, I will infer the implied acceptance criteria from the claim of substantial equivalence and the listed comparison of technological characteristics.

1. A table of acceptance criteria and the reported device performance

Since specific numerical acceptance criteria for performance are not explicitly stated for this 510(k), and the device essentially claims "same as predicate" for performance, the acceptance criteria are implicitly that the software update does not degrade the performance characteristics of the predicate device.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document states, "No clinical tests were conducted to demonstrate substantial equivalence." Therefore, there is no test set of patient data mentioned for evaluating performance in the context of this software update. The verification focused on software requirements and compliance with IEC 62304.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Since no clinical tests using patient data were conducted, no experts were used to establish ground truth for a test set. The validation was against software specifications.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable as no clinical test set requiring adjudication was used.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No MRMC comparative effectiveness study was done, as no clinical tests or human reading evaluations are mentioned for this software update. The device itself is an imaging system with an integrated Computer Aided Surgery (CAS) feature, but the submission doesn't detail performance studies of this CAS feature, instead focusing on the equivalence of the overall system after a software update.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The "Software Verification testing verifying the software requirements perform as intended" and "Results of these validations and verifications confirm that the SURGIVISIO software complies with its specifications" indicate that standalone software testing was performed against specified requirements. However, the specifics of what those requirements are (e.g., accuracy, precision of specific measurements or detections if any) are not detailed. It's a general statement of software verification and validation.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the software verification and validation, the ground truth would be the software specifications and requirements themselves. The software was tested to ensure it met its predefined functional and non-functional requirements.

8. The sample size for the training set

Not applicable/Not provided. This submission is for a software update to an existing imaging system, claiming substantial equivalence based on verification and validation against specifications, not a new AI algorithm that would typically involve a distinct training set. The device description does not imply a machine learning component requiring a training set in the conventional sense for this submission.

9. How the ground truth for the training set was established

Not applicable as no training set is mentioned in the context of this submission.
