Surgical Microscope Position Control Using Image Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microscope devices used in surgical operations require precise control of position and attitude to obtain desired images, which is burdensome for users and prolongs operation time, especially at high magnification factors.
Innovation Solution
A control device and method that uses a captured image to automatically adjust the position and attitude of a microscope unit via an arm unit to satisfy pre-set conditions, reducing user burden and improving convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning of the microscope unit is performed by the user, then the position and attitude can be adjusted, but the user burden increases and operation time is prolonged
Solution Approach 1:
The microscope unit automatically positions and adjusts its own attitude based on captured images and pre-set conditions, without requiring continuous manual intervention. The system captures images, compares them with reference images, and autonomously moves the microscope unit to satisfy positioning conditions, making the system self-servicing.
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated control system that uses image processing and computer-controlled movement. The control unit substitutes for the user's hands by automatically calculating position adjustments based on image comparison and executing precise movements of the microscope unit.
2Measurement precision
If high magnification photographing is performed, then image detail is improved, but positioning precision requirements increase significantly
Solution Approach 1:
The system continuously captures images with the microscope unit, compares them with reference images, and uses this feedback to automatically adjust the position and attitude. This closed-loop feedback mechanism ensures high positioning precision is maintained during high magnification photographing without requiring manual intervention.
Solution Approach 2:
The patent replaces manual positioning with an automated control system that uses image processing algorithms to calculate precise position adjustments. This substitution enables the system to achieve and maintain the required positioning precision for high magnification imaging without human intervention.
3Ease of operation
If automatic positioning is implemented, then user burden is reduced, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions including image capture, image comparison, position calculation, and movement control within a single integrated system. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in overall device complexity while achieving automatic positioning.

AI summary
To make it possible to improve user convenience, provided is a control device including: a control unit configured to control a position and an attitude of a microscope unit by driving an arm unit that supports the microscope unit on the basis of a captured image of an operating site photographed by the microscope unit during an operation so that a position and attitude condition set before the operation is satisfied. The position and attitude condition is a condition that prescribes a position and an attitude of the microscope unit with respect to the operating site to obtain a desired captured image corresponding to the position and attitude condition.
