Indications for Use
The Phasor Drill is a sterile, single-use, disposable device intended for use on adult patients during neurosurgical procedures for drilling of cranial bone.
Device Story
Handheld, sterile, single-use, battery-powered cranial drill; used by clinicians in neurosurgical procedures. Input: manual activation via push-button switch. Operation: 18V power from six series-connected lithium CR2 cells drives a brushed DC motor with integrated gearbox; drill bit serves as motor shaft, eliminating need for chuck or coupling. Output: mechanical rotation of drill bit to bore holes in cranial bone. Features: adjustable thumbscrew drill stop for depth control; blue slider switch for motor rotation reversal. Benefits: provides clinicians with greater mobility and control compared to tethered electrical drills; disposable nature eliminates sterilization requirements.
Clinical Evidence
Bench testing only. No clinical or animal data provided. Bench testing included compression, torque, and drill stop (pull) tests. Packaging integrity verified via accelerated aging (ASTM F1980-07) and distribution challenge testing (ASTM D4169-14). Biocompatibility testing performed per ISO 10993-17:2002 and ISO 10993-18:2005.
Technological Characteristics
Handheld, battery-powered (18V, 6x CR2 lithium cells). Brushed DC motor with integrated gearbox. Drill bits (440A stainless steel, ASTM F899) fixed to motor shaft. Dimensions: 0.75-3.2 mm bit diameter, 75-210 mm length. Sterilization: Gamma. No software or connectivity.
Indications for Use
Indicated for adult patients undergoing neurosurgical procedures requiring drilling of cranial bone.
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.

## Device Description
The Phasor™ Drill is a handheld single unit drill that is a sterile, single use device. The drill includes an ergonomically designed outer shell for ease and maneuverability, a thumbscrew drill stop to ensure the product drills to the preset required depth, and a fixed drill bit made from 440A stainless steel. The Phasor™ Drill is powered by six primary lithium CR2 cells electrically connected in series to provide 18 V. The motor used in the Phasor™ Drill is a brushed DC motor which is designed to be run from a direct current power source, via batteries. The gearbox is integrated into the motor to reduce the rotational speed. The drill bit forms the shaft of the motor eliminating the need for a coupling, chuck or other clutching mechanism. The Phasor™ Drill product family includes various drill sizes depending on the drill bit diameter (0.75-3.2 mm), number of flutes (2 or 3), drill bit length (75-210 mm), and Thumb Screw Drill stop diameters (1.5-3.2 mm). As seen in Figure 1, the Phasor™ Drill has two switches. The ON/OFF button in the front is a momentary push button switch which activates the drill when pressed. The blue slider switch on the top is used for reversing the direction of rotation. The slider switch is a DPDT (double pole; double throw) which reverses the polarity of the drill motor when moved in forward or rearward direction. (See figure 1)

### Biocompatibility Testing
Biocompatibility testing for was performed according to ISO 10993-17:2002 and ISO 10993-18:2005 on both the drill bits and the thumbscrew drill stop. In reference to 440A Stainless Steel, bone drill, manufactured under standard ASTM F899, no further biocompatibility testing is necessary due to the known biocompatibility with human tissue and fluids. Complete biocompatibility testing has also been completed by the plastics supplier of the thumbscrew drill
{6}------------------------------------------------
stop, see Appendix F. It is the opinion of Biotex. Inc. that we have meet the necessary biocompatibility requirements for the intended use of the device.
## Performance Testing - Bench
Results from the performance testing are provided. The laboratory performance testing was conducted to verify suitability of the design characteristics of the testing consisted of the following: Compression Test, Torque, and Drill Stop (Pull). Results of the testing confirmed the PhasorTM meets design requirements, see Appendix C.
## Performance Testing - Animal
No animal testing was performed.
## Performance Testing- Distribution/Aging Packaging Integrity
Distribution Challenge Testing and Accelerated Aging Studies were completed to ensure that product integrity is maintained for the intended use. All testing performed was conformal. Product successfully passed the equivalent of one year of aging.
The following are the utilized guidance documents.
- ASTM F1980-07 (Reapproved 2011), standard guide for accelerated aging of sterile barrier ● systems for medical devices
- ASTM D4169-14, standard practice for performance testing of shipping containers and systems
- ASTM F88/F88M-09, standard test method for seal strength of flexible barrier materials ●
- ASTM F2096-11, standard test method for detecting gross leaks in packaging by internal ● pressurization.
Accelerating aging data to support a one vear shelf life is provided as Appendix D. Also provided in Appendix I is the real time aging protocol which will be used to support a one year and three year shelf life.
## Substantial Equivalence
A comparison of the Phasor™ Drill to the predicate devices is provided below. Like the predicate devices, the Phasor Drill is intended to drill through skull bone. The predicate, MicroAire® 1000E System (K014060), does not come sterile however, it is indicated to be sterilized by means of an autoclave. Like the predicated, Sterile Drill Bits (K962913) and the Phasor Drill are supplied sterile and for single use.
Differences in the intended use between the Phasor Drill and the predicate, MicroAire® 1000E System, are that the Phasor Drill does not integrate any cutting, sawing, decorticating, shaping, or manipulating of bone and/or bone related tissue. The Indication For Use of The Phasor™ Drill is a sterile, single-use, disposable device intended for use on adult patients during neurosurgical procedures for drilling of cranial bone. The Indication For Use of the proposed device differs from the predicate in no new or different type of safety- or effectiveness-related matter.
{7}------------------------------------------------
The Phasor Drill has some differences in technology than the predicate device. The Phasor Drill is powered by 6 CR cell batteries which generate 18 volts of energy. The use of a hand-held battery-powered device provides clinicians with greater control of angle and freedom of mobility than the predicate MicroAire® 1000E System, which is a tethered, electrically-powered drill. The predicate device MicroAire® 1000E System is powered by electricity to energize the motor and spin the drill bit in order to make a hole in the skull of a patient. Although the technology of the proposed device differs from the predicate, it does not raise any new or different types of safety or effectiveness questions.
The predicate drill bits produced by Synthes, Inc. and the Biotex drill bits are made from surgical grade stainless steel and tooled with 2 and 3 channels. The only differences between the drill bits are the sizes which are offered for sale to consumers (please see table below). The Synthes, Inc. drill bits range in size larger than the drill bits produced by Biotex. There is no significant difference in the Indications For Use; due to the age of the Synthes clearance, additional regulatory language has been added to the Biotex Indication For Use statement. As mentioned previously, a difference exists only in the size of the drill bits offered but does not raise any new or different type of safety or effectiveness questions.
The available performance data demonstrates that the Phasor Drill is safe and performs effectively in achieving a drilled hole in the skull. The Phasor Drill, therefore, is substantially equivalent to the other devices regulated under 21 CFR 882.4310 and 21 CFR 878.4820.
