Intended Use

Taps are nonpowered hand-held devices intended for bone cutting and drilling on a patient's skull during fracture repair and reconstructive procedures of the cranium. The taps may be used to prepare cranial bone to insert bone fixation screws.

Device Description

Taps are used to drill a hole and simultaneously create threads in order to accommodate a Rapid Resorbable Fixation System bone screw. The self-drilling fixed-stop taps are manufactured from Stainless Steel 440A which conforms to ASTM F899 Standard Specification for Stainless Steel for Surgical Instruments and ASTM A276 Specification for Stainless Steel Bars and Shapes. The adjustable-length taps (final assembly) are assembled from three components; the adjustable tap (Stainless Steel 440A), the locking collar (Makrolon Rx2530 W/1118 Tint), and the stop collar (Stainless Steel 316L with an aluminum titanium nitride coating).

AI/ML Overview

The provided document describes the Synthes Taps for Resorbable Screws (K153587) and the performance testing conducted to support its substantial equivalence to predicate devices. Here's a breakdown of the requested information based on the document:

1. Table of Acceptance Criteria and Reported Device Performance

TestAcceptance CriteriaReported Device Performance
Simulated Use/Bioskills Lab - RapidSorb InstrumentsFull validation of various aspects of the device design (torque resistance, length, screw size diameter).The results indicated full validation of the subject device. All acceptance criteria were met.
Saw Bones Lab - RapidSorb InstrumentsAll four users must be able to use each of the three subject taps to create three separate tapped holes that accommodate the corresponding screw (36 total insertions).The acceptance criteria was met in that all four users were able to use each of the three subject taps to create three separate tapped holes that will accommodate the corresponding screw (36 total insertions).
Mechanical Test - Torsional Testing of RapidSorb TapsThe failure torque of RapidSorb self-drilling taps must be above the torque at which the same diameter taps will bottom-out in the testing substrate.P-values of 0.000 for all three sizes (1.5, 2.0, and 2.5 mm) when comparing failure torque to bottoming or stripping torque. This is sufficient evidence to reject the null hypothesis, indicating the RapidSorb failure torque is superior, satisfying the acceptance criteria.
Mechanical Test - RapidSorb Self-Drilling Tap Axial Load at Strip OutThe axial force required to cause the adjustable stop to unintentionally move must be greater than the axial force generated by the strip-out torque of each tap.P-value of 0.000 for all comparisons (1.5, 2.0, and 2.5mm) for axial load, indicating the axial load required to move the adjustable stop was superior to the axial load at strip-out in all cases, satisfying the acceptance criteria.
Validation of Hex Coupling for RapidSorb Adjustable TapsAll tested parts must couple with the designated hex handles and then be fully inserted into 40 lbs/cf polyurethane foam with no slippage or visible damage (no magnification) of taps proximal coupling.All participants were able to drive all 12 taps with a combination of the 3 specified handles, with no visible damage to the proximal coupling end of the tap.
Biocompatibility (Cytotoxicity)No reactivity of causing cell lysis or toxicity. All test method acceptance criteria met.The test articles extract showed no reactivity of causing cell lysis or toxicity. All test method acceptance criteria were met.

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

  • Simulated Use/Bioskills Lab:
    • Sample Size: 5 individual participants (users) and 4 cadaveric cephaluses (heads).
    • Data Provenance: Prospective, from cadaveric cephaluses. Likely from the US, given the submission to the FDA.
  • Saw Bones Lab:
    • Sample Size: 4 users and an unspecified number of "saw bones" (synthetic bone models). The test involved 36 total insertions (implying 3 subject taps x 3 tapped holes x 4 users).
    • Data Provenance: Prospective, using synthetic bone models (Sawbones).
  • Mechanical Tests (Torsional, Axial Load, Hex Coupling Validation):
    • Sample Size: For Torsional Testing, all three sizes of RapidSorb Self-Drilling Taps (1.5, 2.0, and 2.5 mm) were tested. For Axial Load, adjustable length taps (311.100, 311.101, 311.102, 311.110, 311.111, 311.112) of 1.5, 2.0, and 2.5mm were compared. For Hex Coupling Validation, 12 taps were driven by "all participants" (number not specified but implied to be multiple, likely the same 5 as the simulated use or similar).
    • Data Provenance: In-vitro / bench testing. No specific country of origin or retrospective/prospective distinction is given for the collected data, but it is implied to be newly generated for this submission.
  • Biocompatibility Testing:
    • Sample Size: Not specified for the extract, but presumably standard in-vitro cell culture methods.
    • Data Provenance: In-vitro lab testing.

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

The concept of "experts" establish ground truth in the traditional sense (e.g., radiologists interpreting images) is not directly applicable here as this is a medical device for surgical procedures (taps).

  • Simulated Use/Bioskills Lab: "The users are independent from the design of the subject device." No specific qualification (e.g., surgeon, resident) or experience level is mentioned for the 5 participants.
  • Saw Bones Lab: 4 users. No specific qualifications mentioned.

For mechanical and biocompatibility testing, the "ground truth" is established by the physical and biological properties being measured against established engineering and biological standards.

4. Adjudication Method for the Test Set

No formal adjudication method (like 2+1 or 3+1 consensus) is described for any of the performance tests. The tests appear to involve direct measurement (mechanical tests) or observed outcomes (simulated use, Sawbones lab), with success defined by meeting the specified acceptance criteria. For the "Simulated Use/Bioskills Lab," "The results indicated full validation... All acceptance criteria were met," suggesting a pass/fail outcome rather than a consensus on a specific finding.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This device is a manual surgical instrument, not an AI or imaging diagnostic tool where MRMC studies are typically performed.

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

This question is not applicable. The device is a physical, manual surgical instrument. There is no "algorithm" or AI component to this device.

7. The Type of Ground Truth Used

The "ground truth" primarily relies on:

  • Performance against engineering specifications: For mechanical tests (torsional, axial load, hex coupling), the ground truth is defined by the device's ability to withstand forces, prevent stripping, and couple correctly according to established engineering benchmarks and statistical comparisons with null hypotheses.
  • Direct observation of functional performance: For the Simulated Use and Saw Bones labs, the ground truth is observed successful drilling/tapping and accommodation of screws by human users, as per the defined acceptance criteria.
  • Biological standards: For biocompatibility, the ground truth is the absence of cytotoxicity, evaluated against ISO 10993-5 guidelines.

8. The Sample Size for the Training Set

No training set is mentioned as this device is not an AI/ML algorithm. The performance data presented are for validation/verification testing.

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

Not applicable, as there is no training set for this type of medical device submission.

INDICATIONS FOR USE

Taps for Resorbable Screws

Taps are nonpowered hand-held devices intended for bone cutting and drilling on a patient's skull during fracture repair and reconstructive procedures of the cranium. The taps may be used to prepare cranial bone to insert bone fixation screws.

Medtronic Sofamor Danak POWEREASE System (Primary Predicate)

IPC® System is indicated for the incision/cutting, removal, drilling and sawing of soft and hard tissue and bone, and biomaterials in Neurosurgical (Craniofacial), Orthopedic, Arthroscopic, Spinal, Sternotomy, and General surgical procedures. The IPC® POWEREASE™ System is indicated for drilling, tapping and driving screws and working end attachments during spinal surgery, including open and minimally invasive procedures. It is also used in placement or cutting of screws, posts and rods.

Discussion

Both the subject taps and the primary predicate Medtronic Sofamor Danek POWEREASE System K123270 are intended for use in neurosurgical procedures to drill or cut into the skull. There is a difference in the assigned FDA product codes:

  • The subject taps are manual instruments, with a corresponding product code of . HBG (Drills, burrs, trephines, and their accessories - manual).
  • The primary predicate is a powered instrument with the corresponding product code of HBE (drills, burrs, trephines, and accessories - simple, powered).

Additionally, the subject taps defined herein as Class II product code HBG are the same instruments currently marketed by Synthes as Class I product code LXH (Orthopedic manual surgical instruments). Thus, the subject taps include the intended uses of both product codes (i.e. cranial bone-cutting and general orthopedic bone cutting).

The reference device Synthes Dental Bone Cutting Instruments K150796 does not have the same intended use as the subject taps since the dental bone cutting instruments are intended for trauma, reconstruction, or orthognathic procedures to drill or cut into the upper or lower jaw. The reference device product code is DZJ (Driver, wire, and Bone Drill Manual). Since taps for general orthopedic bone-cutting would typically be considered Class I Exempt instruments, the identified reference device is included to show that taps have been previously cleared within premarket notification submissions.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

Primary Predicate

DePuy Synthes considers the subject taps equivalent to the Medtronic Sofamor Danek Sofamor Danek POWEREASE™ System K123270, as well as the Synthes Dental Bone Cutting Instruments K150796.

  • The Medtronic IPC® and POWEREASE™ Systems (K123270) are used in ● Neurosurgical (Cranial, Craniofacial), Orthopedic, Arthroscopic, Spinal, Sternotomy, and General surgical procedures; the subject taps are intended for neurosurgical procedures only

Impact on Safety and Effectiveness

There is no impact to safety and effectiveness. The subject devices have a limited intended use compared to the predicate device; the POWEREASE System is used for drilling, tapping, and driving screws while the taps are used to cut bone in preparation of receiving a bone screw. The subject devices are basic handheld instruments compared to the predicate; the tap is connected to a handle (dependent on the coupling feature) while the predicate device consists of a handpiece and multiple attachments. The subject devices are used manually while the predicate can be used either manually or with power.

Reference Device

Both the subject taps and the reference Dental Bone Cutting Instruments (K150796) are generally intended to be used during surgery for cutting into bone. The reference device is included to show that taps have been cleared within premarket submissions.

Technological Similarities of Taps to the Reference Device

  • Both devices are intended to be used to prepare bone for placement of a screw
  • Both devices are operated manually ●
  • Both are manufactured from stainless steel (440A) .

Technological Differences of Taps to the Reference Device

Performance Testing - Bench
TestTest Method SummaryResults
Mechanical Test - TorsionalTesting of RapidSorb TapsThe objective of this test is todemonstrate that the failuretorque of RapidSorb self-drillingtaps is above the torque at whichthe same diameter taps willbottom-out in the testingsubstrate. Two separate tests willbe performed, Failure TorqueTest and Stripping Torque Test.The results of this testing indicatethat when the failure torque of allthree sizes of RapidSorb SelfDrilling Taps (1.5, 2.0, and 2.5mm) are compared to theirrespective bottoming or strippingtorque, the resulting p-valueswere all 0.000. There issufficient evidence to reject thenull hypothesis in favor of thealternate, that in all cases theRapidSorb failure torque issuperior to the Bottoming orStripping torque (as specified).This satisfies the acceptancecriteria.
Mechanical Test - RapidSorbSelf-Drilling Tap Axial Load atStrip OutThe objective of this test was todemonstrate that the axial forcerequired to cause the adjustablestop on the adjustable length taps(311.100, 311.101, 311.102,311.110, 311.111, 311.112) tounintentionally move is greaterthan the axial force that isgenerated by the strip out torqueof each tap.As can be seen in all comparisons(1.5, 2.0, and 2.5mm) theresulting p-value was 0.000,which is sufficient evidence toreject the null hypothesis in favorof the alternate that the Axialload required to move theadjustable stop was superior tothe axial load at strip-out in allcases. This result satisfies theacceptance criteria.
Validation of Hex Coupling forRapidSorb Adjustable TapsThe objective of this test was tovalidate the compatibility of theHex coupling on the proximal endof the RapidSorb Adjustablelength taps. All tested parts willcouple with the designated hexhandles and, then be fully insertedinto 40 lbs/cf polyurethane foamwith no slippage or visibledamage (no magnification) oftaps proximal coupling.At the conclusion of the testing,all participants were able to driveall 12 taps with a combination ofthe 3 specified handles. This wasdone with no visible damage tothe proximal coupling end of thetap.
Biocompatibility (Cytotoxicity)An in vitro study was conductedto evaluate for potential cytotoxiceffects, following guidelines ofthe ANSI/AAMI/ISO 10993-5,Biological Evaluation of medicaldevices – Part 5: Test for in vitrocytotoxicity (2009).At the conclusion of the testing,the test articles extract showed noreactivity of causing cell lysis ortoxicity. All test methodacceptance criteria were met.The patient contactingcomponents of taps aremanufactured from StainlessSteel 440A which conforms tothe FDA recognized consensusstandard, ASTM F899 - StandardSpecification for Stainless Steelfor Surgical Instruments,supporting the biocompatibilityof this device.
