Surgify Halo is a sterile surgical burr indicated for shaping and removal of hard tissue and bone in Neurosurgical, Spinal, ENT, and General Surgical procedures.

The Surgify Halo is a sterile-packaged, single-use rotary cutting device (a burr) made from high-grade metallic materials, designed to cut bone and other hard tissues selectively while minimizing chattering. The device is similar to conventional surgical cutting burrs but includes a ring mechanism in the burr head to reduce chattering. Like traditional burrs, the device is designed to be compatible with commonly marketed, high-speed, surgical drill systems. The Surgify Halo comprises: Shank, Locking Features, Burr Head, and Safety Mechanism (a self-centering ring and spring mechanism installed in the burr head). The moving ring, larger than the burr head, can adopt two positions: First Position (Hard Tissue Mode) where the ring protrudes, preventing cutting edges from engaging, and Second Position (Soft Tissue Mode) where the ring extends beyond the cutting edge, shielding it to minimize accidental soft tissues and an exposed position for cutting hard surfaces like bone.

The Surgify Halo is a sterile surgical burr used for shaping and removing hard tissue and bone in neurosurgical, spinal, ENT, and general surgical procedures. The company performed performance testing and design validation/summative evaluation to demonstrate substantial equivalence to its predicate device (K250380).

Surgify Halo is a sterile surgical burr indicated for shaping and bone in neurosurgical, spinal, ENT, and general surgical procedures.

The Surgify Halo is a rotary cutting device made of high-grade metallic materials. It cuts bone and other hard tissues selectively while reducing chattering. The device is similar to conventional surgical cutting burrs with the addition of a ring mechanism installed in the burr head to reduce chattering. Similar to conventional burrs, the device is designed for use with compatible high-speed surgical drill systems. The Surgify Halo comprises: A shank, which transfers rotary movement of the drill motor to the head. Locking features at the distal end of the shank which allow the burr shank to be locked to a high-speed surgical drill. A head that is shaped to have two cutting edges to cut bone and hard tissue. A safety mechanism consisting of a ring and spring installed in the burr head. The mechanism is self-centering and comprises a spring and a moving ring that is bigger than the burr head. The moving ring can have two different positions: In the first position, the ring protrudes to a level higher than cutting edges and prevents the cutting edges from cutting into the work material. In the second position, the ring retracts into the groove to a level lower than the cutting edges to allow the burr to cut the work material

The provided text describes the Surgify Halo, a sterile surgical burr, and its performance evaluation to demonstrate substantial equivalence to a predicate device (Adeor HiCut Highspeed Instrument).

Here's an analysis of the acceptance criteria and the study details:

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

The document does not explicitly present a table of formal acceptance criteria with specific numerical thresholds. Instead, it states that "All tests fulfilled Design input requirements" and that the "performance of the Surgify Halo burr was comparable to that of the conventional diamond and fluted burrs." This implies that the acceptance criteria were defined by the product's design input requirements and the performance of established devices.

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 does not specify the sample sizes used for any of the individual tests. Similarly, there is no information provided regarding the provenance of the data (e.g., country of origin, retrospective or prospective nature). The testing appears to be primarily laboratory-based "Design Verification Test" and "Design Validation Testing." The "Performance Testing Animal" section suggests an animal model was used, but details are not provided.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

The document mentions "Nurses Summative Testing" and "Surgeons Summative Testing" for Design Validation/Usability. These tests involved a "series of tests based on hazard-related use scenario, user interface." However, the number of nurses and surgeons involved, their specific qualifications, or how their input established a "ground truth" (beyond fulfilling design input requirements for usability) is not detailed.

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

No information is provided regarding an adjudication method. The testing seems to be based on meeting predefined design input requirements and comparative performance, rather than a system requiring expert adjudication of ambiguous cases.

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

This section is not applicable. The Surgify Halo is a physical surgical burr, not an AI-assisted diagnostic or imaging device. Therefore, an MRMC study related to human readers and AI assistance would not be relevant.

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

This section is not applicable. The Surgify Halo is a physical surgical burr. Its performance is inherent to the device itself (e.g., cutting efficiency, durability), not a standalone algorithm.

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

The "ground truth" for the performance evaluation appears to be based on:

• Design Input Requirements: The device was tested against its own design specifications (e.g., durability, cutting efficiency, noise levels, geometrical features).
• Predicate Device Comparability: The performance of the Surgify Halo was compared to that of "conventional diamond and fluted burrs," implying these established devices served as a benchmark for acceptable performance.
• Biocompatibility Standards: Compliance with ISO 10993-1:2018.
• Sterilization Standards: Compliance with EN/ISO 11137-1/2 (2015).
• Usability Feedback: Input from nurses and surgeons during summative testing to ensure the device meets intended use and user needs.

The drill also has an auto-stop feature which detects when the bit breaks through the inner table of the skull and immediately stops the drill. The device has an LED indicator which indicates to the user (green) when they are applying enough force and (red) when the drill stops.

The drill features mechanical plunge prevention with a tapered stainless steel drill may be reactivated any number of times using the trigger if the physician desires.

The provided text describes performance testing for the Hubly Electric Drill. However, it does not contain specific numerical acceptance criteria or numerical reported device performance in a table format, nor does it detail a study proving the device meets specific acceptance criteria in the way requested.

Instead, the document outlines various tests conducted to demonstrate the device's substantial equivalence to a predicate device and its safety and effectiveness.

Here's an attempt to extract and synthesize the information based on the request, noting where information is not explicitly provided in the text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not provide a table with explicit numerical acceptance criteria and corresponding reported device performance values. It generally states that the device "meets all design specifications and requirements" for bench tests and "all in vivo requirements were met" for the animal study.

2. Sample Size Used for the Test Set and Data Provenance

• Test Set Sample Size: The document does not specify a numerical sample size for any of the performance tests (bench testing, animal study).
• Data Provenance:
  • Bench Testing: Conducted by Hubly Inc. (implied, as they are the applicant).
  • Animal Study: Conducted in a GLP (Good Laboratory Practice) compliant setting using a sheep model. The location/country is not specified.
  • Retrospective/Prospective: The tests described (bench, animal) are prospective studies conducted to support the 510(k) submission.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts

• This information is not provided in the document. The studies described are performance tests and an animal study, not studies relying on expert review for ground truth establishment.

4. Adjudication Method for the Test Set

• This information is not applicable/provided. The described tests are instrumental/procedural performance tests and an animal study, not studies involving human reader interpretation requiring adjudication.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The document explicitly states: "Clinical testing was not performed on human subjects." The studies focused on bench performance and an animal model.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

• The Hubly Electric Drill is a physical medical device (a drill), not an AI algorithm. Therefore, a standalone algorithm performance study is not applicable. The "software verification testing" was conducted on firmware responsible for the automatic stopping feature, but this is an embedded system, not a standalone AI application. The software implements "additional safety features" and has a "Moderate" level of concern.

7. Type of Ground Truth Used

• Bench Testing: Ground truth was implicitly based on engineering design specifications and requirements (e.g., battery life, depth of penetration, trigger performance).
• Animal Study: Ground truth was based on observational outcomes in the sheep model, specifically demonstrating that "Users (Test Device Evaluators) could safely use the Hubly Electric Drill for intracranial access without damaging the dura or brain tissue."

8. Sample Size for the Training Set

• This information is not applicable/provided. The device is a physical drill with embedded firmware, not a machine learning model that requires a training set in the conventional sense. The "software" mentioned is firmware, which is typically developed through traditional software engineering processes, not trained on data.

9. How the Ground Truth for the Training Set Was Established

• This information is not applicable/provided for the reasons stated in point 8.
