Medical application solutions have been incorporating miniaturization in order to provide more tools for surgical and medical use that can perform high precision operations with an extremely small margin of error. Miniaturized tools and DC micro motors have been developed for another surgical aspect – that of a surgeon’s vision.
It is a common sight to see a surgeon wearing a pair of magnifying glasses when performing a procedure. However, these spectacles are really inadequate in an era where medical procedures are becoming increasingly precise and quickly shrinking in scale. Fixed magnifying glasses limit the field of vision and a very small range where the lens are in focus.
This problem has set the framework for a medical application solution that incorporates auto-focus features with a full range of motion.
Head Mounted Vision System
A solution for enhanced vision for a surgeon has a hefty lift of specifications. The vision system must be hands free and light weight in order to be comfortably worn over long periods of time. In order to perform better than fixed lens, a wide range of magnification factors and an automatic focus are needed in order to compensate as a surgeon moves his head and operates in a different location. For extended functionality, the vision system needs to incorporate integrated lighting to handle shadows and an optional output to video camera provides a precise record everything a surgeon sees.
Clearly, these specifications are rather vigorous when coupled with the need to have all of this equipment fit comfortably in a doctor’s field of vision.
How DC Micro Motors Provide the Technical Solution
The system specified above will have a number of moving parts that have to respond quickly and accurately to a surgeon’s vision. Precision movements are achieved with a system of DC micro motors and DC gear-motors. Each lens requires two DC micro motors in order to properly set the order of magnification and focus distance. In order to achieve a high level of precision for a 10 micrometer resolution, the DC micro motors are equipped with a high quality set of magnets and coils supplemented with specialty lubricants to lower initial torque requirements.
The lubrication and fine surfaces are responsible for minimizing friction for higher resolution operation without jolts or backlash. Within the casing, the coils and magnets can reach temperatures over 100 degrees Celsius in order to operate continuously for several days without any limitation on service life or effectiveness thanks to the minimal amount of friction.
DC micro motors and other miniaturized components continue to lead the way in paving new innovations for medical application solutions. The ultimate goal of any miniaturized system is to obtain a maximum precision in the minimum space. This head mounted vision system is ideal for demanding positioning tasks, ranging from optical filters and focusing units to distribution of medical samples, inner-tube valves, and other micro positioning systems. Surgical tools continue to evolve in step with the medical field to the benefit of patients everywhere.
