Norsk språkHow to Select OPTO-EDU Surgical Operation Microscope?
|
What is Surgical Operation Microscope? The Surgical Microscope, or Operation Microscope, is an optical microscope that provides the surgeon with a stereoscopic, high quality magnified and illuminated image of the small structures in the surgical area. The optical components of a basic stereo microscope consist of the binocular head, a magnification changer, the objective lens and an illuminator which beams light through the objective lens and onto the operating field. The binocular head consists of two telescopes with adjustable eyepieces. The magnification can be changed by turning a knob (which selects different magnification lenses) or by using a motorised zoom controlled by a foot pedal. The working distance is the distance from the microscope objective lens to the point of focus of the optical system. This value is fixed and is dependent on the chosen focal length of the objective lens. The choice of working distance depends on the type of surgery. For modern ophthalmic surgery that involves delicate work in the posterior chamber, objective focal lengths of 150 mm, 175 mm and 200 mm are commonly used. For ENT, Dental surgery, it should be 250mm or larger to see deep inside the throat. The advanced surgical models may be equipped with a large zoom range objective lens which can supply 200-500mm working distance. The optical system often includes a beam splitter and a second set of teaching binoculars (Figure so that two people can view the operation simultaneously, and add a digital camera to output the image to monitor for easy sharing. |

The optical system is attached to the suspension arm of the floor stand . The suspension arm makes it possible to position the optics exactly and to fix them in place. The floor stand has wheels and can be moved around the floor and fixed into place using the brakes. A foot pedal connected to the floor stand allows the surgeon to control the focus, the zoom, the position of the optics over the eye (the x,y position on the horizontal plane) and to turn the illumination on and off. The illumination system is usually housed in the floor stand in order to keep the bulb heat away from the operating field. In this case, the light is transmitted to the operating field by means of a fibre optic cable. The light in ophthalmic micro scopes is usually coaxial, meaning that it follows the same path as the image in order to avoid shadows. |

How to select a surgical microscope & accessory The structure and principle of the operating microscope are generally the same, but there are some differences in various parameters and accessories according to the specific operation conditions used. Choosing the right operating microscope starts with knowing what surgery you will be doing: ENT and Dental, Orthopedic Surgery, Ophthalmology, Neurosurgery and Brain Surgery. Secondly, the performance (budget) is divided - do you need to manually divide and zoom? (cheap) or manual continuous zoom? (medium) or motorized zoom? (more expensive) to choose. Finally, select the details, such as multi-functional pedals, electromagnetic locks, cameras, displays and other accessories are needed. The following list is some main models of surgical microscopes, and the application fields of each model can be seen in the far right column, which is convenient for customers to choose from. |
