Surgical power tool

Accidents, fractures, emergency surgery. In the operating room, doctors must focus and quickly provide the best medical assistance to patients. If the fracture site must be secured with splints and screws, the surgeon will pick up the bone drill and begin operation. Such scenes are performed every day in hospitals around the world. The widespread use of electric devices has greatly reduced the workload of surgeons. With the help of such electric devices, surgeons can even heal serious injuries that were previously only treated with amputation. Technological advances in power tools have reduced the invasiveness of surgical treatment, minimizing tissue damage and reducing recovery time.

When it comes to surgical handheld devices, most of us immediately associate the large machines used by artisans. However, surgical instruments must meet much higher requirements in terms of accuracy, heat generation and vibration. In addition, reliability is also an important factor. DC motors that power power tools must also meet the same high requirements. Therefore, brushless DC drives are particularly suitable here because of their long life and high speed. These two features are especially important for surgeons using surgical scalpels on knee or shoulder joints (see Figure 1) because their use is to specifically remove specific tissue and cartilage in a targeted manner during surgery. This type of instrument is equipped with a long stainless steel tube with a rotating blade at the end opening. Here you can use, for example, the McCormick Brushless EC13 motor as a drive with a GP13 planetary gearbox. The motor can reach speeds of up to 90,000 revolutions per minute and is sealed and preserved. For scrapers, sealing and preservation are critical because they must often be in direct contact with saline. In addition, the heat and vibration generated by the motor must be limited to a minimum, so that the surgeon's work is more convenient.
