Endoscope Arm Motion Control for Wider Laparoscopic Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing endoscopic surgical apparatus limits the imaging range, restricting the ability to capture desired images during surgeries.
Innovation Solution
An information processing apparatus that controls the motion of an arm section supporting the camera, allowing for various imaging options by adjusting the position and attitude of the endoscope, enabling wider range imaging and zoom operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the cropping position of the captured image is controlled, then the focus on the treatment tool is improved, but the imaging range is limited
Solution Approach 1:
The arm section is made dynamically controllable, allowing real-time adjustment of the endoscope's position and attitude. This enables the system to switch between focused views (improving measurement precision) and wide-angle views (expanding imaging range) based on surgical needs, resolving the contradiction between focus and range.
Solution Approach 2:
The invention adds spatial dimensionality control by adjusting the arm section's position and attitude in three-dimensional space. This allows the endoscope to capture images from multiple angles and distances, simultaneously achieving focused detail views and comprehensive wide-area imaging that cannot be obtained with fixed cropping alone.
2Adaptability or versatility
If the arm section motion is controlled for various imaging, then the imaging versatility is improved, but the device complexity increases
Solution Approach 1:
The arm section is designed as a multi-functional platform that can perform multiple imaging tasks (wide-area capture, focused detail imaging, angled views) through a single integrated structure. This universal design achieves imaging versatility without proportionally increasing device complexity, as the same arm mechanism serves multiple purposes.
Solution Approach 2:
The system achieves versatility by changing operational parameters (arm position, arm attitude, endoscope orientation) rather than adding multiple fixed configurations. This parameter-based adaptability allows the same hardware to perform diverse imaging functions, improving versatility while minimizing the increase in device complexity.

AI summary
[Problem] A surgical apparatus of the related art controls only the cropping position of a captured image, and thus only executes a limited range of image control in laparoscopic surgery. [Solution] A medical information processing apparatus including: an image control section that controls processing of a captured image from a camera; and an arm control section that controls a motion of an arm that supports the camera. One of the image control section and the arm control section executes control on a basis of control information from another control section.
