Power Surgical Instruments

Surgical power tools help surgeons complete surgeries quicker and with more precision. These tools use air, battery or nitrogen for power, which reduces the chance of releasing a spark and exploding the highly explosive gases used by anesthesiologist. Surgical power tools allow surgeons the convenience of having an extensive amount of attachments for various purposes, which results in a higher degree of flexibility.

  1. Power Surgical Saws

    • Power surgical saws need to have a reciprocating back and forth action or oscillating side to side motion for bone cutting. Air power gives the bone saw more power and safety. The Hall saw is an example of a surgical bone saw. Developed by an oral surgeon named Robert M. Hall and manufactured by the Aro Corp, the saw looks similar to a dentist drill. Known as the "Hall Saw," the tool can turn 100,000 revolutions per minute and employs burs that can drill neat holes in bone or, if moved sideways, slices neatly like a regular power saw. It will not, however, saw through soft tissues. Fingers placed in on the burs are not to cut but to stop the saw. This saw brings pin point accuracy to bone saws because of its lightness and agility.

    Surgical Drills

    • There are different types of surgical drills depending on the type of material the drill is working with. Surgical drills have a rapid rotary action for hole drilling or carving bone. Powered by either air, battery or nitrogen, these drills insert surgical pins, wires and screws. Some drills require a high degree of technology when drilling into highly sensitive areas such as around the ear. Dr. David Proops along with some colleagues in Great Britain developed a drill for use in ear surgery. The drill bores holes in the side of a patients head to set implants while also protecting delicate ear membranes. When the drill encounters tissue, it alerts the surgeon, which eliminates the guess work characteristic of the old drills.

    Power Shaver

    • Arthroscopic surgery uses a series of small incisions to repair ligaments and joints. This type of surgery uses minute power tools. A common arthroscopic tool is the surgical power shaver. The Dyonics company developed the first power shavers., which has small knives housed inside a tube. For example, this shaver cuts the meniscus in the knee for knee surgeries. The tube has oval windows that expose the knives where suction pulls the tissue toward the knives and into the widow. The knives or shaver is a hand held tool.
