Description

Surgical microscope

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a surgical microscope.

Background

In microsurgery, the microscope eyepiece used to view the surgical field is increasingly replaced by two cameras and a screen. In this process, the camera records the field through the imaging optics of the microscope and displays the image of the field through the screen. Such a surgical microscope, which is composed of a microscope body and a screen, has many advantages, including: ergonomically better conditions for the surgeon, multiple options for digital image processing and enhanced images, and more training options for future surgeons.

Typically, 3D images of a 3D screen are optimal only at a certain relative spatial position, i.e. a certain distance and a certain angle with respect to the viewer, which is called "optimal position". The relative spatial position is determined by the selected 3D screen, which needs to be considered in the design and manufacturing process, i.e. within a certain range around the "optimal position" to provide a three-dimensional display effect in a realistic manner. Therefore, when using the 3D screen, the distance between the surgeon and the 3D screen, and the rotation and tilt angle of the 3D screen should be maintained at the "optimal position" as much as possible with respect to the viewing direction of the surgeon.

In the existing operation microscope, the microscope body and the 3D screen are connected to the bracket through the kinematic system, and in the operation process, the microscope body is required to be repositioned relatively frequently with a patient, so that the position of the 3D screen is changed accordingly, the distance and angle of the 3D screen relative to a surgeon are changed, the influence on the image quality is large, the ergonomic requirement is not met, the observation is not facilitated, the operation efficiency is reduced, the deflection angle of the 3D screen can only be changed when the existing bracket is in front view, so that a proper 3D image can be observed conveniently, but the distance from the 3D screen to the surgeon cannot be adjusted, and visual fatigue is easily caused.
