Microscope Deflecting Device for Ergonomic Display Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microscopes used in microsurgery require operators to look directly through eyepieces, limiting their unimpeded view of the operating area and preventing the simultaneous observation of enlarged images on a display.
Innovation Solution
A microscope design featuring a deflecting device within the display apparatus that redirects light beams from the object into the optics, allowing the display to be positioned ergonomically and enabling the operator to view the operating area on a screen without direct eye alignment, using technologies like LCDs, OELs, or switchable mirrors for deflection and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator looks directly through the eyepieces of the microscope, then a magnified view of the operating area is obtained, but the unimpeded view of the operating area is limited
Solution Approach 1:
The invention introduces a display dimension by projecting the magnified image onto a display screen that the operator can view from a distance. This adds a new viewing dimension beyond the traditional eyepiece, allowing the operator to see the magnified image on a screen while maintaining an unimpeded view of the operating area, thus resolving the contradiction between magnified view and ease of operation.
2Measurement precision
If the display apparatus is positioned close to the object for optimal viewing, then the magnified image quality is improved, but the operator's freedom of movement is restricted
Solution Approach 1:
The invention segments the optical path by introducing a beam splitter or deflecting device that separates the light path from the object into two channels: one to the display screen and another to the eyepieces. This segmentation allows the display to be positioned at a distance from the object while still receiving a clear magnified image, thereby maintaining both image quality and operator freedom of movement.
3Power
If the eyepieces are positioned close to the object, then the magnification is maximized, but the operator cannot maintain a natural viewing position
Solution Approach 1:
The invention introduces an intermediary display screen between the operator and the microscope optics. The beam splitter or deflecting device acts as an intermediary that redirects light to the display while allowing the operator to view the operating area naturally. This intermediary system enables the operator to maintain a natural viewing position while still accessing the magnified image, resolving the contradiction between magnification and ease of operation.
