Medical Microscope Opto-Mechanical Layout for Ergonomic Field Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical microscopes have complex optical systems and limited adjustability of the field of view, requiring operators to change their ergonomic posture when adjusting the field of view, which can lead to physical stress during examinations and treatments.
Innovation Solution
A medical microscope with an opto-mechanical system that allows flexible adjustment of the field of view through pivot and rotation movements, decoupling the microscope body from the ocular system, enabling three-dimensional repositioning without changing the operator's ergonomic posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the microscope body is rigidly connected to the ocular system, then the structural complexity is reduced, but the field of view adjustability is limited and operator ergonomics deteriorate
Solution Approach 1:
The microscope is divided into separate functional modules: the ocular system remains fixed while the microscope body can be independently positioned through pivot and rotation movements. This segmentation allows the field of view to be adjusted without moving the oculars, resolving the contradiction between adjustability and structural simplicity.
Solution Approach 2:
The opto-mechanical system employs nested rotational and pivotal movements where the microscope body can rotate around a vertical axis and pivot around a horizontal axis, creating a compact multi-degree-of-freedom positioning mechanism that provides extensive field of view adjustment within a confined structural footprint.
2Ease of operation
If the microscope body is decoupled from the ocular system with multiple degrees of freedom, then the field of view can be freely adjusted, but the device complexity increases
Solution Approach 1:
The opto-mechanical system is designed to automatically maintain the optical axis alignment during pivot and rotation movements, eliminating the need for manual realignment by the operator. The system self-compensates for positional changes, reducing operational complexity despite the increased mechanical degrees of freedom.
3Adaptability or versatility
If the ocular system is fixed in position, then the operator's posture remains stable, but the field of view cannot be relocated without moving the entire microscope
Solution Approach 1:
The system adds rotational and pivotal dimensions to the microscope body positioning, allowing field of view relocation in multiple spatial dimensions while the ocular system remains fixed in its original position. This multi-dimensional movement capability enables comprehensive field of view adjustment without ocular displacement.

AI summary
A medical microscope includes an eyepiece system having a binocular, an eyepiece base body supporting the binocular, and a suspension attached to the eyepiece base body securing the microscope to a support system. A microscope body has an objective lens for capturing light from a field of view associated with a microscope axis corresponding to a section of an optical symmetry axis extending from the microscope body to the field of view. An opto-mechanical system positioned between the eyepiece system and the microscope body channels light captured to the binocular. The opto-mechanical system allows pivoting movement of the microscope body about a pivot axis and has a rotation unit for moving the microscope body about a first axis of rotation extending coaxially, parallel or at an angle in the range of 0° to 5° to a section of the optical symmetry axis extending through the rotation unit.
