Stereoscopic Assembly Optical Path Deflection for Surgical Microscope Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic arrangements in surgical microscopes and kits face challenges in reducing space occupancy, which obstructs the surgeon's view of the monitor and operating space, especially when the viewing angle needs to be changed.
Innovation Solution
The proposed solution involves guiding a sub-path between the deflection unit and the image sensor at an acute angle to the plane spanned by the stereoscopic base and another sub-path between the objective unit and the deflection unit, and arranging at least one lens group between the deflection unit and the image sensor to optimize the optical path and reduce space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stereoscopic arrangement is pivoted to change the viewing angle, then the viewing angle can be adjusted, but the surgeon's view of the monitor is obstructed
Solution Approach 1:
The optical paths are deflected out of the plane containing the stereoscopic base and the first sub-paths, directing the second sub-paths away from the surgeon's line of sight. This dimensional change in optical path orientation allows viewing angle adjustment without obstructing the surgeon's view of the monitor.
2Ease of operation
If the optical paths are deflected out of the plane to avoid obstructing the surgeon's view, then the surgeon's view is maintained, but the space occupied by the arrangement increases
Solution Approach 1:
The optical paths are deflected out of the plane containing the stereoscopic base and the first sub-paths, directing the second sub-paths away from the surgeon's line of sight. This dimensional change in optical path orientation allows viewing angle adjustment without obstructing the surgeon's view of the monitor.
3Volume of moving object
If the arrangement is made more compact to reduce space occupancy, then the space occupied is reduced, but the optical paths may obstruct the surgeon's view
Solution Approach 1:
The optical paths are deflected out of the plane containing the stereoscopic base and the first sub-paths, directing the second sub-paths away from the surgeon's line of sight. This dimensional change in optical path orientation allows viewing angle adjustment without obstructing the surgeon's view of the monitor.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows the optical paths to be guided away from the main viewing area, maintaining a clear line of sight for the surgeon and optimizing the use of space, thereby improving ergonomics and use characteristics during medical procedures.

AI summary
A stereoscopic arrangement that includes at least one of each of an objective unit, deflection unit, lens group arrangement and at least one image sensor. In this case, an optical sub-path between the deflection unit and the image sensor should be at an acute angle to a plane spanned by an optical sub-path, running between the objective unit and the deflection unit, of the same optical path and the stereoscopic base. In addition, at least one lens group of a lens group arrangement is intended to be provided between the deflection unit and the image sensor. Also, in a stereoscopic arrangement, at least two optical paths can run in a common plane. Further, a surgical microscope having such a stereoscopic arrangement is provided.
