Medical Power Tools

Medical power tools are every bit as necessary as normal medical tools in today's world, and even make the job faster and simpler. They range from the smallest of tools to the largest, any medical tool that needs a power supply, whether plug-in or battery, can be called a medical power tool.

Medical power tools range in size from very tiny pen-like tools to large fridge-sized machines. An ultrasound machine, heart monitor, mammogram machine, xray machine can all be classed as medical power tools, but so can the tiny tools used in microsurgery. Specialized light and magnifying units for seeing into eyes, ears and throats are power tools, as are some modern electric stethoscopes.

Surgery makes use of many medical power tools, from tools needed to make small incisions and bone cuts, to small drills, to small imaging machines like scopes and probes that are used both inside and outside the body.

Large medical power tools have a lot of room for changes, but the tiny power tools need all the brains the researchers can muster. They must invent motors that can fit inside a very small housing, yet maintain their power, torque and functionality. And they must pay special attention to all effects of that smallness, since they must keep vibration to a minimum, make sure the motor doesn't overheat or heat up the physician's hand too much, and resist high humidity and contact with many fluids and substances. Companies are now specializing in motors smaller than 10mm in diameter... that's a whole powerful motor inside about half of your finger's tip!
