Tools and disposable components warnings W50 W51 W52 W53 W54 W55 W56 W57 W58 W59 W60 W61 W62 W63 2
Keep the cutting area of the tool away from fingers and loose clothing to prevent laceration of user and cross-contamination through compromised glove. Operate the tool only after appropriate anatomical landmarks at the intended surgical site have been confirmed. Use care in application of the rotating cutting end to only appropriate anatomical landmarks and the intended surgical site when using powered accessories. Bending or prying may break the accessory, causing harm to patient or user. A tool’s size and geometry may create excessive vibration at certain speeds. Increase or decrease speed of the motor to prevent vibration. Test for wobble at desired speed prior to use. Discontinue use of accessory if tool tip wobbles and replace accessory to prevent unintended tissue removal. Carefully inspect dissecting tool both prior to and following each use for signs of excessive wear, fragmentation, eccentricities, or other defects. Replace any suspicious dissecting tools with a new one prior to use. Excessive noise from the tool when drilling close to the cochlea or ossicular chain may cause hearing damage. Tools with “L” identification are longer tools intended for light bone dissection. The increased tool head/stem configuration may affect dissection stability. Do not re-sharpen used tools. Worn tools should be frequently replaced with new ones to ensure effective cutting and control. Excessive pressure applied to bur may cause bur fracture. Should a tool fracture in use, extreme care must be exercised to ensure that all fragments of the tool are removed from the patient. Do not use metal-cutting tools to cut/resect bone. Use only rotary tools specifically designed for use with the Medtronic Midas Rex Legend drill system. Do not use an accessory if its packaging is opened or damaged. Sterility may be compromised if packaging is opened or damaged.
Midas Rex™ Legend™ Pneumatic High-Speed System W64 W65 W66 W67 W68
Properly dispose of single-use devices removed from sterile packages. Devices lose sterility upon removal from packaging. Do not use dull tools. Use of dull tools can reduce cutting effectiveness and can cause the motor temperature to increase. Always ensure that the tool is secured in the motor or attachment prior to operating the system. Exposure of tool packaging to light for extended periods of time may cause damage to packaging. Do not use or re-process a dissecting tool that has already been used. Using a dissecting tool that has already been used may cause injury to the patient, operator and/or operating room staff or contamination. Using a dissecting tool that has already been used may affect motor performance. W69 Do not use an attachment and dissecting tool combination if tool flail or excessive vibration occurs. W70 Dissecting tool flutes are sharp and may perforate surgical gloves.
Legend pneumatic control unit warnings W71 W72 W73 W74
Do not use the Legend pneumatic control unit to operate any other systems except for Legend pneumatic motors and TRITON Power Surgical Instrument Systems. Do not disassemble equipment before gas pressure is released from Legend pneumatic control unit and associated hoses. Do not carry Legend pneumatic control unit by the N2 DISS pressure hose. Do not use the pneumatic control unit to operate systems other than the Midas Rex and TRITON pneumatic systems.
Legend lubricant/diffuser cartridge warnings W75 W76 W77 W78
Failure to properly secure Legend lubricant/diffuser cartridge may cause injury to operator and/or operating room staff. Do not attempt to remove the lubricant/diffuser cartridge while the system is pressurized. Do not use a Legend pneumatic motor without a lubricant/diffuser installed. Do not use a lubricant/diffuser cartridge if it appears to be damaged, or if the inner foil seal is punctured.
Cautions C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 C16 C17 C18 C19 C20 C21 C22 C23
When using an angled attachment, hold the motor assembly by the attachment so that the attachment does not inadvertently loosen from the motor. Do not use twist drill or contra-angle tool/attachment at an operating pressure over 80 psi (5.5 bar). Do not kink hoses. Inspect hoses for cracks, tears, or corrosion. The use of a washer-disinfector for cleaning may cause a pre-mature degradation in performance. Remove devices from instrument case before placing into washer-disinfector and allow devices to drain. Orient devices in the washer-disinfector by following manufacturer recommendations. Do not use low-temperature hydrogen peroxide gas plasma sterilization due to the lumen internal diameter and length restrictions. Do not use low-temperature liquid peracetic acid sterilization due to immersion procedure. Remove and discard accessories following local regulations for disposal of contaminated materials. Do not run the motor at an operating pressure above or below the required operating pressure range. Operating pressure below 80 psi (5.5 bar) may not provide proper lubrication to the motor. Operating pressure above 120 psi (8.3 bar) may damage or reduce the life of the motor. Do not autoclave the pneumatic adapter. Legend pneumatic control unit and pressure hose should not be sterilized. Do not exceed 1 hour drill time per surgery for a Legend lubricant/diffuser. Use only Legend dissecting tools with a Legend pneumatic motor. Do not attempt to remove Legend lubricant/diffuser while the motor is in operation. Do not attempt to refill a used lubricant/diffuser cartridge. Do not sterilize the lubricant/diffuser cartridge. The lubricant/diffuser cartridge may melt into the lubricant/diffuser housing with potential damage to the motor. The lubricant/diffuser cartridge must be removed from the motor’s lubricant/diffuser housing prior to sterilization. When using angled attachments with the Legend Gold Touch, extend the lever on the Finger Control and hold by the attachment. If the motor has an uncomfortable temperature to touch/ hold following sterilization, allow an adequate “cool down” period. If the motor has an uncomfortable temperature to touch/ hold and an adequate “cool down” period was used, check that a new Legend lubricant/diffuser is properly attached to the motor’s lubricant/diffuser housing to help cool down motor. Run the motor briefly to assist in its cool down. The Legend Gold, Gold Touch, and Platinum lubricant/diffuser cartridge (PA100-A) is not interchangeable with the MR7 lubricant/diffuser cartridge (PA700). Ensure you select the appropriate lubricant/diffuser cartridge for the motor. During a lengthy surgical procedure with extended motor use, lubricant may drip from lubricant/diffuser cartridge. Do not re-use a lubricant/diffuser cartridge. It is a single-use product. Remove lubricant/diffuser cartridge from motor assembly prior to sterilizing it.

Operating (dynamic) pressure may be checked diagnostically at the Legend or MR7 pneumatic control unit while the motor is running. Operating pressure will decrease slightly from the non-running (static) pressure setting when the motor is activated. Adjust operating pressure as needed at the compressed gas source until supply pressure gauge on Legend or MR7 pneumatic control unit reads within a range of 80 – 120 psi (5.5 –8.3 bar), as required. To ensure optimal motor performance, set nominal operating pressure to 100 psi (6.9 bar). If the surgeon requests additional power during a procedure, compressed gas source may be turned up to an operating pressure of 120 psi (8.3 bar). To decrease pressure, turn down the in-house compressed gas source or loosen the pressure handle on the regulator. Push down on the pressure relief at the pneumatic control unit to exhaust excess pressure. 7
