Warnings

Do not use the Midas Rex MR7 System before proper cleaning and sterilization.

Do not operate the Midas Rex MR7 System in the presence of Magnetic Resonance Imaging devices.

Do not use damaged, faulty, or modified Midas Rex MR7 System components. Inspect the Midas Rex MR7 System for damage prior to each use:

  • Check the motor’s exhaust hose for cracks or tears.
  • Visually inspect attachments and tools. Do not use bent or damaged tools.
  • Install attachment and dissecting tool, then briefly run motor.
    • Check motor for overheating and leaking lubricant. 
    • Check attachment for overheating. 
    • Check dissecting tool for flail.
  • Do not operate the Midas Rex MR7 System without eye protection.
  • Motors and attachments which fail due to extended use may allow a component to detach and fall from the motor or attachment, and may cause patient injury.
  • Heavy side loads and/or long operating periods may cause the device to overheat. If overheating occurs:
    • Never place an overheated motor on the patient or draping during surgery.
    • Discontinue use and rest the motor by using intermittently, or wrap the motor/attachment interface with a moist sterile towel.
    • If the motor is passed off, the receiver should grasp the motor by the proximal end close to the motor hose.
  • To avoid injury to the patient or user, do not place the handpiece on the patient or in an unsecured location, when not in use.
  • Midas Rex MR7 motors should only be operated when the attachment is in the position.

If a dissecting tool package is opened, but the tool is not used or contaminated, the tool can be re-sterilized by steam sterilization. Remove tool from all original packaging and place into an approved autoclave package. Steam sterilize as follows:

High Vacuum Steam: 270° F (132° C) for 5 minutes
Gravity Displacement: 270° F (132° C) for 15 minutes

The re-sterilized tool must be used promptly following re-sterilization. If rust or corrosion is encountered after re-sterilization, do not use the re-sterilized tool.
