Intended Use
The Anspach Surgical Drill, Specialty Nosepiece Attachment “Adaptor/Coupler” is indicated for use by trained medical personnel as an interface coupling device, to permit attachment to and operation of the Medtronic, Midas Rex “Legend” Bone Mill (BM100) and Disposable Bowl (BM200) with an Anspach motor.
Device Story
The Adaptor/Coupler is a mechanical interface device; cylindrical housing with external locking feature. It attaches to Anspach surgical drill motors to enable operation of Medtronic Midas Rex Legend Bone Mills. Operation involves simple insertion/twist motion to align cantilever tabs with bone mill D-lock feature; detachment via pull motion to depress tabs. Used in surgical settings by trained medical personnel. Device transfers motor speed/torque to bone mill input spindle. Benefits include enabling compatibility between Anspach motor systems and Medtronic bone processing equipment.
Clinical Evidence
Bench testing only. No clinical data provided.
Technological Characteristics
Stainless steel construction; corrosion-resistant bearings. Mechanical coupling via cylindrical housing with cantilever tabs. Compatible with pneumatic and electric motors. Max operating temperature 120°C. Sterilization via steam or Sterrad. No software or electronic components.
Indications for Use
Indicated for use by trained medical personnel as an interface coupling device to connect Anspach motors to Medtronic Midas Rex Legend Bone Mill (BM100) and Disposable Bowl (BM200). Contraindicated for use by untrained personnel or as a nosepiece attachment for any other competitive device.
Regulatory Classification
Identification
Powered simple cranial drills, burrs, trephines, and their accessories are bone cutting and drilling instruments used on a patient's skull. The instruments are used with a power source but do not have a clutch mechanism to disengage the tip after penetrating the skull.

Exhibit 16-01
510(k) SUMMARY: -
CLASSIFICATION NAME: Powered simple cranial drills, burrs trephines and their accessories
COMMON/USUAL NAMES: Nosepiece attachment; nose-tube; Coupler, Adaptor, etc.
CLASSIFICATION: US Class II / EU Class IIa
APPLIED (PERFORMANCE) STANDARDS:
There are no known standards established for powered, simple cranial drills, burrs, trephines, and their accessories at this time. There are no known performance standards for bone mills or adaptors for powering devices for bone mills. Appropriate international accepted standards for materials identification and testing, and Quality /Management Systems are applied.
SUMMARY:
The Coupler is a simple attachment; comprised of a cylindrical housing with external locking feature, that when inserted into the bone mill, physically locks the coupler to the bone mill. The coupler is designed to attach and lock onto the Anspach drill motor drive shaft, to permit transfer of motor speed/torque to the bone mill input spindle (drive shaft).
There are two coupler designs; one for Black Max and one for Micro/Max/xMax and eMax.
Attachment is a simple insertion/twist motion, to align cantilever tabs with the Bone Mill "D-lock" feature. Detachment is a simple pull motion that depresses the two coupler cantilever tabs, unlocking coupler from the bone mill for easy removal.
IDENTIFIED ADDITIONAL RISKS:
Locking tab damage or excessive/premature wear:
Appropriate design considerations (materials, design, etc.) for such wear are incorporated and design safety factors exceed predetermined design requirements.
Bone mill design change to inhibit use of the Anspach motor/coupler assembly:
Thought possible, it would be highly unlikely as it would require a similar design revision to all currently distributed Midas Rex Motors and/or bone mills.
INDICATIONS / CONTRAINDICATIONS:
The Anspach Surgical Drill, Specialty Nosepiece Attachment "Adaptor/Coupler" is indicated for use by trained medical personnel as an interface coupling device, to permit attachment to and operation of the Medtronic, Midas Rex "Legend" Bone Mill (BM100) and Disposable Bowl (BM200) with an Anspach motor. It is contraindicated for use by untrained personnel or as a nosepiece attachment for any other competitive device.

## CLEANING/STERILIZATION/MAINTENANCE:
The Anspach Coupler is distributed clean, non-sterilized and is intended to be a re-usable device. The coupler is not expected to be subjected to gross bio-contamination, but contact with soiled gloves could cause external bio-contamination. Validated cleaning, disinfection, sterilization, and routine maintenance recommendations are provided in product use manuals available to all purchasers and Instructions (Directions) For Use (IFU/DFU) that accompany each product.
The Anspach Coupler is not serviceable by user or third parties but remains fully serviceable by Anspach. Unauthorized service/repair activities can invalidate warranty.
## WARNINGS and CAUTIONS:
Generic Warnings and Cautions for use of Anspach motor systems, attachments and cutters are specified on product inserts. For safe and effective use of any Anspach product, it is strongly suggested that specialized training be undertaken since surgical techniques using Anspach products are highly specialized and complex procedures. Improper surgical technique or improper use of Anspach products can cause severe injury or death to a user or patient and cause severe damage to Anspach products and/or other equipment.
## SUBSTANTIAL EQUIVALENCE:
The Anspach coupler is substantially equivalent to other Anspach Attachments in that it is attached to an Anspach surgical drill motor to accept and support a bone cutting/ processing device (cutter, saw, perforator, chuck system, etc.).
