Microscopes are used in medicine for a variety of uses other than checking laboratory samples. One such specialized application is for ENT examination and treatment. ENT microscopes are used for close examination of the cramped ear, nose and throat passages.
Need for ENT Microscope
The patients often require close attention because hearing, breathing, balance, taste and saliva production are all connected to the health of the ear, nose and throat passages. The bones and tissues of the passages are very delicate and require a lot of care during examination and surgery. ENT microscopes are particularly important because of the sensitive nature of the procedures.
The medical professional can closely examine the problem areas with the device. The examining physician may use the microscope either for examination or for conducting an operation. Pictures of the affected area may need to be taken for later viewing by the examining physician.
Features of ENT Microscope
In appearance the ENT microscope looks a lot like a high end video camera attached to a swing arm. Here a major difference from regular cameras is that the microscope lens is illuminated to view the affected area. Dual optical tubes are used by the physician to get a clear-distortion free view.
The ENT microscope may be mounted on a wheeled floor stand for moving from room to room for different procedures. The floor stand also keeps the microscope stable from toppling over. This allows hospitals to use the instrument in multiple examining rooms, if the need arises. The device can also be moved out of the way once examination is complete. Another configuration is wall-mounting the ENT microscope. The microscope can be folded away after the physician has completed the use.
The ENT microscope has dual folding arms which carry all the sensor and electronics with the camera module fixed at the end of the arm. This gives the instrument a good reach and flexibility as desired by the physician to check the ear, nose and throat passages. The microscope can be swung and adjusted using grab handles. The focus can be adjusted using a single knob with additional fin focus options available. The binocular tubes can be extended or retracted depending on the physician’s comfort.
The ENT microscope gives a good resolution image at the tissue level. The powerful LED light source provides a good clear image. A digital camera module can be used to take high quality pictures for later examination. The video stream can also be fed to a display unit or digital storage unit if required for later viewing.
Intuitive to Use
The microscope has a motion sensor which turns the device on when the viewing unit is swung into position by the operator. When the use of the device is over, the operating physician can just swing the arm upward and away to turn off the LED light source. Since the LED source is a major component of the microscope, this feature can extend the life of the unit significantly.
