Endoscope Distal End Raising Base for Tool Direction Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems face challenges in accurately adjusting the direction of treatment tools during procedures, as the current mechanisms for rotating treatment tool stands do not ensure consistent capture within the endoscopic image field, affecting the precision and usability of the tool's position and posture.
Innovation Solution
The endoscope distal end is equipped with a rotatable raising base that abuts against the treatment tool, allowing it to adjust the tool's protrusion direction and ensuring that the treatment tool stand's trajectory is consistently captured within the imager's three-dimensional observation area, regardless of its rotational position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the raising base is made rotatable to adjust treatment tool direction, then the adaptability and ease of operation are improved, but the reliability of consistent capture within the image field deteriorates
Solution Approach 1:
The imager is configured to perform three-dimensional imaging, creating a volumetric observation area that encompasses the raising base's rotational trajectory. This dimensional expansion from two-dimensional plane capture to three-dimensional volumetric capture ensures the raising base remains within the observable space throughout its rotation, resolving the reliability issue while preserving rotational adaptability
2Measurement precision
If the imager captures a larger three-dimensional area to include the raising base trajectory, then the measurement precision and visibility are improved, but the device complexity increases
Solution Approach 1:
The imager is designed with multi-functionality, serving both traditional two-dimensional endoscopic imaging and three-dimensional volumetric imaging that tracks the raising base. This universal design allows a single imaging system to fulfill multiple functions without requiring separate dedicated devices, thereby improving measurement precision while limiting the increase in device complexity

AI summary
A distal end portion for use with an endoscope includes: an imager configured to capture an image of a predetermined three-dimensional area; and a raising base configured to be rotatable in a predetermined rotational range, the raising base configured to abut against a treatment tool to adjust a direction in which the treatment tool protrudes. The imager is arranged such that a portion of the raising base is in the predetermined three-dimensional area when the raising base is positioned anywhere within the predetermined rotation range.
