Shaver Handpieces User Guide

Warnings and Cautions Warnings To avoid potential serious injury to the user and the patient and/or damage to this device, the user must obey the following warnings:

Prior to Surgery • •

•

• •

Federal law (United States of America) restricts these devices to use by, or on order of, a physician. To avoid potential serious injury to the user and patient and/or damage to these devices, read this user guide and the user guides for other components, namely the console, the footswitch, and the cutting blade thoroughly and be familiar with its contents prior to using this equipment. Before using the handpieces in a surgical procedure, inspect it for any damage. Ensure that there are no loose or missing components and that all parts move freely. Do not use the equipment if damage is apparent. Set up the entire system and verify each function before introducing a handpiece to the surgical site. Clean and sterilize the handpiece prior to the first use and every use thereafter.

During Surgery •

•

•

The handpieces are designed to be used by a qualified physician familiar with arthroscopic procedures. Misusing the handpieces may cause damage to both the patient and system components. The handpieces generate electronic noise that may interfere with EKG readings. Should EKG readings become erratic while a handpiece is in use, power down the handpiece before reacting to the EKG reading, to ensure the electronic interference is not causing inaccurate EKG readings. Do not operate the handpiece unless the shaver blade is immersed in solution and suction is activated (at least 5 in. Hg). Failure to do so may result in abnormal wear of the cutting surfaces, overheating, particulate generation, and accumulation of unwanted materials in the surgical site. EN-3

•

Do not bend shaver blades or use them for prying. Excessive pressure on them may cause it to break and may cause harm to the patient and operating-room staff. Broken pieces may also enter the surgical site, where they will be difficult to remove.

•

Running arthroscopic shaver blades at speeds greater than 6000 RPM may result in particulate generation.

•

To avoid possible user injury, never attempt to change the blade while the handpiece is running. For Formula® handpieces use only Formula® arthroscopic shaver blades (375-XXX-XXX, 380-XXX-XXX, 385-XXX-XXX) and Crossfire™ Xtreme arthroscopic shaver blades (475-XXX-XXX, 480-XXX-XXX, and 485-XXX-XXX). Using unapproved blades may cause unexpected results. For a complete list of shaver blades, contact your Stryker representative or Stryker customer service. For TPS Small Joint handpiece, use only small joint shaver blades (275-627-000, 275-637-000, 275-628-000, 275-638-000, 275-641-000, 275-647-000). Using unapproved shaver blades may cause unexpected results. For a complete list of shaver blades, contact your Stryker representative or Stryker customer service. Do not modify shaver blades in any way. Modifying shaver blades may cause product damage and personal injury to the patient and operating-room staff. Broken pieces may also enter the surgical site, where they will be difficult to remove. Avoid contacting shaver blades with metal objects. Do not insert metal objects in the shaver blade window. If shaver blades contact metal objects, they may break, leaving pieces in the surgical site where they will be difficult to remove. Do not use this device in the presence of flammable anaesthetics, other flammable gases or objects, near flammable fluids such as skin prepping agents and tinctures, or oxidizing agents. Observe appropriate fire precautions at all times. Do not use this device in oxygen-enriched atmospheres, nitrous oxide (N2O) atmospheres, or in the presence of other oxidizing agents, to prevent risk of explosion. Ensure that oxygen connections are not leaking.

Cleaning and Sterilization

Warning

•

To minimize the risk of infection, clean and sterilize the handpiece prior to the first use and every use thereafter.

•

Ensure the suction lever is completely in the on position during sterilization. Drying time depends on several variables, including: altitude, humidity, type of wrap, preconditioning, size of chamber, mass of load, material of load, and placement in chamber. Users must verify that drying time set in their autoclave yields dry surgical equipment.

•

Cautions •

•

•

For Formula® handpieces, always install the soaking cap prior to cleaning or sterilization. If moisture reaches the connection pins of the cable connector, it could damage the connector. Do not cross-sterilize the handpiece. Alternating between different methods of sterilization may cause undue wear on the handpiece. Product longevity is extended by the consistent use of a single sterilization method. Do not leave the handpiece in solutions longer than necessary. This may accelerate normal product aging.

Limits on Reprocessing • •

Using multiple sterilization methods may significantly reduce the performance of the device and is not recommended. Damage incurred by improper processing will not be covered by the warranty.
