Structural Configurations and Applications of Surgical Microscopes
The advent of surgical microscopes and advances in surgical techniques have given rise to a brand-new discipline - microsurgery. Microsurgery employs surgical microscopes to perform delicate procedures such as anastomosis of small blood vessels, and is widely applied in ophthalmology, otolaryngology (ENT), general surgery, gynecology and plastic surgery.
Traditional surgical microscopes are binocular stereo microscopes that deliver stereoscopic vision during observation to ensure smooth surgical operations. They feature variable magnification from 1.6× to 80×, a sufficiently large working distance of 9 cm to 40 cm, and a wide objective field of view typically ranging from 15 mm to 40 mm. Modern surgical microscopes are fitted with a video imaging system, also referred to as a microsurgical video system.
The ASOM series surgical microscopes are independently developed by Chengdu Keao Optoelectronic Technology Co., Ltd. They adopt a high-resolution, high-definition optical system with strong stereoscopic perception and large depth of focus. Available in a variety of structural forms, they fall into two main categories: mobile and fixed. The mobile type is further divided into column type and clamp-mounted type, while the fixed type includes ceiling-mounted, wall-mounted and other variants.
A surgical microscope is composed of an observation system, an illumination system, a support stand, and a photographic/video display system. The observation system has two independent optical paths that form images of the target at a set angle, delivering a stereoscopic image when viewed through the two eyepieces. The photographic or video camera system connects to the surgical microscope via an optical interface and displays the surgical field on a monitor, enabling multi-person viewing, clinical consultation, teaching and research, as well as video recording and archiving.
