A xyster is a surgical instrument used to scrape bones during procedures such as bone grafting, biopsy, and bone repair. It is made from sterilizable materials and must be regularly checked for wear and tear. The term “xyster” comes from the Greek word for “to scrape”.
A xyster is a surgical instrument that is used to scrape bones. Xysters are used in both human and veterinary surgery, in a variety of procedures involving bone and attached tissue. This tool is available from medical supply companies that make surgical instruments. Some of these companies will only sell to hospitals or doctors, due to concerns about misuse of medical tools or people who may be providing medical services without a license, potentially putting patients at risk.
The xyster looks like a rasp or file. It is used to clean the bone during surgical procedures. Orthopedic surgeons may use this tool when preparing bone for grafting, preparing to take a biopsy sample, or preparing to fix or otherwise repair severely damaged bone. Veterinarians, including veterinarians who specialize in orthopedic procedures, use this tool in much the same way.
Like other surgical instruments, xyster is made from a material designed to be sterilized. The tool can be washed in specialized soaps and withstand a trip through an autoclave to kill any bacteria and other organisms that may be present. It is also regularly checked for signs of metal fatigue or dulling which could be indicators for replacement. Dulling of the tool can make it less useful and potentially injure a patient, making it important to evaluate the tool to confirm it is in good condition before use.
Along with other surgical instruments, xyster is accurately registered by surgical personnel. If the instrument is likely to be needed during surgery, it will be arranged during operating room set-up so that it is easily accessible. The instrument will normally be left in an autoclave pouch to maintain sterility and to indicate that it is sterile, with an assistant opening the pouch for the surgeon when the instrument is needed. The instrument is also counted after surgery, along with other equipment used, by a nurse or surgical assistant who is tasked with ensuring that all instruments are accounted for.
The term “xyster” originated in the 1600s and derives from a Greek root which means “to scrape”. Like other surgical instruments, training is required to learn how to use the instrument effectively and to determine when instrument use will be appropriate. Surgery training is done under the supervision of experienced surgeons, often according to the old protocol of “see one, do one, teach one”.
