Sterilizable Motors and Their Surgical Applications

Surgeons all over the world use a variety of motorized tools to get the job done. Motorized hand drills of different sizes, for example, are used in many kinds of surgeries ranging from dental operations to joint repair and spinal surgeries.

Strict rules regarding sterilization of items used before a surgical procedure means the tools must be put in an autoclave for sterilization. Sterilization kills off the bacteria, but it can also cause wear and tear to the tools being sterilized. Regular miniature motors can easily get damaged by the high temperatures inside an autoclave, which means surgical tools must use sterilizable motors instead.

Silent Operation and Precision

Professionals performing surgical procedures must be completely focused on the task when working, so there should be minimal, if any, distractions. This is why sterilizable motors are also designed to run as silently as possible. Although the sound from a working sterilized motor won’t be completely muted, it is a lot better than the louder noise generated by conventional miniature motors.

Precision is also a necessity, especially since the smallest mistake can lead to dangerous consequences. Sterilizable motors are designed to be lightweight in order to give users more control over the device. These motors also typically have smaller dimensions in order to make them more compact and to make them fit into more ergonomic tool bodies.

Lastly, sterilizable motors for surgical tools are also designed to deal with vibrations. While it’s not a major issue for some applications, excessive vibration can pose a serious risk in delicate surgical procedures because it affects the stability of a handheld motorized tool. Sterilizable motors are built to work at full power while creating as little vibration as possible.

Surgeries Made More Efficient

Sterilizable motors are valuable in various fields of medical care, particularly in surgical procedures. The following are just a few examples of how this technology is used.

  1. Otorhinolaryngology (ENT) – Even the least invasive surgeries benefit greatly from sterilizable motors. Sterilizable micro brushless motors provide just enough torque and speed to power devices such as ENT micro-debrider, which is commonly used for performing surgery on the ear, nose, and throat (ENT). The small, compact size is perfect for ENT surgical tools because the area being worked on are often narrow cavities. Furthermore, mini motors are designed to generate as little heat as possible, another important factor when operating on the most delicate areas of the ears, nose, and throat
  2. Dentistry – This branch of health care also requires the use of compact, silent tools, so sterilizable mini motors are also incorporated into dentistry devices. This is evidently seen in dental procedures that involve drilling or contouring. Plenty of power is required when drilling through hard teeth and jawbone, something that sterilizable motors can efficiently provide.
  3. Orthopedics – Orthopedics is easily the type of healthcare that relies the most on motorized tools. Working with cartilage and bone tissue require plenty of drilling power. This is something that small- to medium-sized sterilizable motors can produce without causing excessive vibrations that could risk further tissue damage during surgery. These motors are commonly found in bone drills and arthroscopic joint shavers, which are supposed to work at very high RPMs (7,000 or more). More powerful drills for larger bones such as the femur or shoulder bones require even larger, more powerful sterilizable drills.

Sterilizable motors are proof of how technology has completely transformed the quality of medical care. Thanks to these motors, surgeons and other medical professionals have access to tools that help make surgical operations safe, faster, and with cleaner results.
