1.1 Operating Principle The MPower 2 Battery Handpieces (PRO6200M, PRO6202M, PRO6212M, PRO6300M, PRO6350M, PRO6400M, PRO6450M) are powered by a detachable, rechargeable battery to provide rotary, reciprocating, or oscillating force to the accessory (drill bits, saw blades, reamers, drivers or other attachments) for bone cutting, drilling, driving and soft tissue resection. The handpieces are controlled by an activation trigger and safety/direction lever on the handpiece. The handpieces and accessories, including the batteries may come into physical contact with the patient (applied part).

1.2 Indications for Use The MPower 2 PRO6200M Battery Single-Trigger Handpiece, the MPower 2 PRO6202M and PRO6212M Battery TwoTrigger Handpieces, and their accessories, perform cutting of soft tissue and bone. The fields of application include: orthopedic, arthroscopic, hand and foot surgical procedures. The MPower 2 PRO6300M and PRO6350M Battery Oscillator Handpiece and their accessories, perform cutting of soft tissue and bone. The fields of application include: orthopedic, arthroscopic, hand and foot surgical procedures. The MPower 2 PRO6400M Battery Reciprocator Handpiece and its accessories, perform cutting of soft tissue and bone. The fields of application include: orthopedic, and arthroscopic surgical procedures. The MPower 2 PRO6450M Battery Sternum Saw, and its accessories, perform cutting of soft tissue and bone. The fields of application include: orthopedic, and arthroscopic surgical procedures.

1.3 Intended Use Same as Indications for Use above.

1.4 Contraindications The MPower 2 PRO6450M Battery Sternum Saw is not intended for use in repeat sternotomy applications.

1.5 Warnings and Precautions Do not bypass this section. It contains warnings and precautions that must be thoroughly understood before operating any of the equipment. Lack of understanding or adherence to these warnings and precautions may result in injury or even death to the patient. The words WARNING, PRECAUTION, and NOTE carry special meanings and they must be read carefully. 1

WARNING: A warning contains critical information regarding serious adverse reactions and potential safety hazards that can occur in proper use or misuse of the equipment. Failure to observe the information or procedures presented in a Warning may result in injury or other serious adverse reactions to the patient and/or surgical staff. PRECAUTION: A precaution contains instructions for any special care to be exercised by the practitioner for the safe and effective use of the equipment. Failure to observe the information or procedures presented in a Precaution may result in damage to the equipment. NOTE: A note is added to provide additional focused information. This information has no critical effect on the patient or equipmen

1.5.1 Warnings 1. Eye protection is recommended when operating equipment. Eye injury may result. 2. I t is the surgeon’s responsibility to be familiar with the appropriate surgical techniques prior to use of the equipment and its associated accessories. 3. Do not use equipment if, upon receipt, package is opened, damaged, or shows any signs of tampering. 4. D  o not use equipment in the presence of flammable anesthetics, gases, disinfecting agents, cleaning solutions, or any material susceptible to ignition due to electrical sparking. 5. D  o not use sterile equipment beyond the expiration date listed on the label. Sterility of the product cannot be assured beyond the expiration date. 6. Handpieces are supplied non-sterile. Clean and sterilize prior to each use. 7. Do not contact the moving parts on the handpieces. Injury to the operator may occur. 8. C  ontinually check handpiece for overheating. If overheating is sensed, immediately discontinue use and return equipment for service. Overheating of the blade or bur may cause damage to the blade or bur and may cause burns or thermal necrosis. 9. W hile handpiece is not in use do not place on patient/surgical drapes. Place handpiece on mayo stand. 10. Do not immerse the equipment in fluids. Immersion may render the device inoperable. 11. Failure to follow the specified service interval could result in reduced instrument performance or overheating of the handpiece. Overheating can lead to possible burn injury to the patient or medical personnel. Rotation of handpiece usage per day will assist with proper performance. (Refer to section “3.4 Maintenance Schedule”). 12. Do not attach, insert or remove accessories or attachments while the handpiece is operating. Injury to the operator and/or damage to the equipment may occur. Place the handpiece safety mechanism in the “safe” position prior to installation or removal of items. 13. Avoid contact with cutting tip of blade or bur when locking into handpiece. Tips are sharp and may cause injury. 14. After use blades, burs and tubing sets may be a potential biohazard and should be handled and disposed in accordance with acceptable medical practice and applicable local and national requirements. 15. Do not use burs for plunge cutting. Injury or damage may occur. 16. Disposable blades and burs are supplied sterile and are for single-use only. Do not resterilize or reuse. The ability to effectively clean and re-sterilize these single use devices has not been established and subsequent reuse may adversely affect the performance, safety and/or sterility of the devices. 17. Do not operate the oscillating saw or reciprocator handpiece without a blade locked securely in place. 2

18. Always place the handpiece in the “safe” position when not in use and prior to repositioning the rotating head on the Oscillator Saw, rotating the collet on the Reciprocating Saw, or connecting or removing attachments and accessories. 19. W hen using the PowerPro Sagittal Saw attachment (PRO2043), placing excessive bending or twisting force on the sagittal saw blade may cause the collet to open and release the saw blade. Do not use saw blades to pry, remove bone grafts, or as a leverage point. Patient or user injury could occur. 20. Do not short circuit battery terminals or allow them to contact metal objects. This could cause a shock or burn injury and also damage the battery. 21. Do not expose batteries to fire or incineration. Exposure may cause injuries. 22. Inspect battery pack for damage (e.g., cracks in battery case) prior to use. Do not use damaged battery packs. If battery pack is damaged and leakage or residue is noticed, do not allow it to come in contact with skin, eyes or clothing. Burns may result. If contact occurs, flush area with copious amounts of water and seek medical attention immediately. Dispose of or recycle properly.
