Introduction

An operating or surgical binocular microscope is an optical device that presents the surgeon with a stereoscopic vision, and a high-quality magnified and illuminated image of the minute structures in the surgical region. The surgical microscope is usually used to perform microsurgery. Primarily a radical idea, the operating microscope has turned into a necessary tool since the first known usage of the binocular microscope during surgery. Its powerful stereoscopic magnification and illumination of the operative bed prompted its quick acceptance by numerous surgeons all over the world.

The introduction of the surgical microscope in the operating room opened a new chapter in the history of microsurgery. It extended the limits of the field, enhanced patient outcomes, and made the development of subspecialties possible. It granted access to regions of the brain and spinal cord that were previously thought to be impossible to reach. The increased magnification allowed for smaller incisions, enhanced visibility, and dissection of sensitive tissues. It provided sufficient hemostasis when working through constricted and deep surgical sites and also frequently helped to cut down the time period of the surgery and decrease anesthetic dangers. On the whole, the binocular surgical microscope has been extensively used in the fields of neurosurgery, plastic surgery, dentistry (particularly endodontics), ENT surgical procedures, and ophthalmic surgeries.

Ever since the surgical microscope has been introduced into the operating room, various factors like the size, focus, and flexibility of the microscope have proved to be challenging, and solutions have frequently led to new issues. According to an estimate, the majority of surgeons may spend around 40% of their total time during surgery to make adjustments to the surgical microscope. Focusing is normally manual, even though some more advanced microscopes have an autofocus aspect included. The advanced technology of surgical instrument tracking autofocus will have the capacity to extensively reduce the surgical duration and furthermore enhance the efficiency of the surgeon.

In general, a surgical microscope may cost a few thousand dollars for a basic model, whereas highly developed models might be significantly more costly. Additionally, specialized microsurgical tools might be needed to take full advantage of the enhanced vision the microscope provides. It may take time to ace the operational aspect of the surgical microscope. However, the surgical microscope is unmistakably superior to the customary surgical loupes that require high magnification and adjustable focus. Even so, the complex mobility and the elevated cost of the surgical microscope have given rise to the necessity for more transportable solutions. A head-mounted operating microscope was lately launched in the market. It brings together the portability of the surgical loupes and the magnification and focusing capacity of a microscope.

A fundamental feature of any surgical microscope is its design.  The device is designed in such a manner that the surgeon concentrates fully on the surgical procedure while remaining comfortable and free of eye strain. The design of the microscope likewise frees the surgeon’s hands to operate. Most of the microsurgical operations take place in a small space or through narrow gaps and in these cases, it is imperative to the surgeon that he retains a sufficiently well-lit binocular vision in the recesses of the area. In such circumstances, the stereoscopic perspective provided by the binocular surgical microscope is the most valuable feature of the device.

The binocular surgical microscope serves two major functions: magnification of the operative field and illumination. With the assistance of a foot or hand switch, it can enlarge structures up to 40+ times. Along with increased magnification, an inbuilt halogen or Xenon lamp gives outstanding lighting right above the surgical area. Advanced microscopes can self-adjust the strength of the illumination to avoid tissue damage, as the microscope shifts nearer or further away from the operative field. Additionally, the surgical microscope has three oculars. One of the oculars is positioned on the side; it tends to fit on either side of the central oculars. The adjustments may affect the stability of the microscope, and the device requires balance prior to its usage. Auto-balance features are as easy as the push of a button and have the capacity to re-balance the microscope securely during the process.

The binocular surgical microscope is comprised of numerous joints to allow for 180° movement, including adjustments for the various seating positions of the patient. The commercial surgical microscopes are mainly positioned on a wheelbase.  They can be placed inside the operating room or shifted from one room then onto the next. The modern surgical microscopes are equipped with cameras that can capture high-resolution images or record high-quality videos. These pictures and video recordings can be stored in integrated or external hard drives or memory sticks, or even transferred onto DVD and Blu-ray discs.

Principles

The magnification of an image is a dependent value and depends on the size of an image as projected on top of the retina of the eye. Consequently, the magnification of a picture is increased by merely reducing the distance between the eye and the object. When the object in question draws nearer to the observing eye, the size of the projected image on the retina is increased.  If the retinal region covered by the projected image is doubled, then the magnification would be observed as 2x or two times larger than what it was before, taking the preceding position as a base value. With the utilization of the binocular microscope, and without altering the distance value, the size of the reflected image of an item can be increased on the retina. The amount of increase, at that point, turns into the magnification value of the specific binocular microscope, for example, a 7x binocular has a predetermined estimate of increasing by seven-fold.

The light that the surgical microscope illuminator transmits to enlighten the surgical site can be varied. One method to change the light is to vary the voltage to the light bulb. The majority of the microscope floor stand power supplies have a prerequisite to change the strength of the light by this technique. Below the microscope, a particular amount of light will be transmitted, and any adjustment made in the magnification of the microscope will have no impact on the amount of light being transmitted from the microscope. However, variations made in the magnification of the microscope do enhance or reduce the amount of light which will be transmitted back through the microscope and on top of the retina of the eye of the observer.

Furthermore, the surgical microscope is capable of providing stereoscopic vision in confined spaces by decreasing the required interpupillary distance needed for binocular vision. The distance between the frontal lenses of the binocular tube of the microscope is just 16 mm, while the standard interpupillary distance is around 60 mm. This implies that light reflected from deep basal structures towards the surgical microscope during an operation utilizing fissure, sulci
