Endoscope Dual Camera Angular Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopes used in minimally invasive surgery lack the ability for full adjustment and manipulation, limiting their application range.
Innovation Solution
An endoscope design featuring two camera units with intersecting optical axes, driven by a driving portion that allows for angular adjustments, either synchronously or asynchronously, enabling more extensive movement and positioning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single camera unit is used in the endoscope, then the device structure is simple, but the adjustment range and manipulation capability are limited
Solution Approach 1:
The endoscope is segmented into multiple camera units (at least two) with independent optical axes, allowing each camera to capture images from different angles. This segmentation enables broader adjustment range and manipulation capability while maintaining a modular structure that can be driven by a common driving portion.
Solution Approach 2:
The driving portion is designed to universally drive multiple camera units simultaneously, providing synchronized angular adjustment capability. This multi-functional driving mechanism allows the endoscope to achieve comprehensive manipulation while avoiding the need for separate driving systems for each camera.
2Adaptability or versatility
If multiple camera units are added to increase adjustment capability, then the application range is expanded, but the device complexity increases
Solution Approach 1:
Multiple camera units are merged into a single integrated endoscope body with a common driving portion that controls all cameras. The driving portion combines multiple driving mechanisms into one unified structure, reducing overall device complexity while maintaining enhanced manipulation capability through coordinated camera movement.
3Adaptability or versatility
If the optical axes of camera units are made parallel, then the alignment is simple, but the imaging versatility is reduced
Solution Approach 1:
The optical axes of the multiple camera units are intentionally arranged asymmetrically relative to each other, with at least two cameras having non-parallel optical axes. This asymmetric arrangement enables the endoscope to capture images from multiple angles simultaneously, greatly enhancing imaging versatility and manipulation capability.

AI summary
The application discloses an endoscope and an operating arm. The endoscope includes two camera units and a driving portion. The camera units are configured to obtain images. Optical axes of the two camera units can intersect. The driving portion is connected to the two camera units for driving at least one camera unit to move, thereby changing an angle between the optical axes of the two camera units. The endoscope is capable of being adjusted as needed, and the application range is wide.
