Solution Overview

Problem

Existing endoscopes face challenges in precisely transmitting pivoting movements to bending movements of the deflecting portion, making it difficult for users to operate them, especially in narrow spaces and requiring improved handling and stability.

Innovation Solution

A secondary endoscope design featuring a grip body with a catheter channel, a control element, and a mounting connecting piece for attachment to a mother endoscope, allowing for safe and clear handling of pivoting movements through a joystick-like control element and a catheter channel that guides the catheter, ensuring stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the control element is positioned on the distal side of the grip body, then the transmission of pivoting movement to the deflecting portion is more precise, but the ease of operation deteriorates as the control element becomes difficult to access

Engineering Contradiction:

Improvetransmission precisionVSAvoidcontrol element accessibility

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The control element is inverted from its conventional distal position to a proximal position on the grip body, allowing the user to operate it easily while still achieving precise transmission to the deflecting portion through the catheter channel guidance system

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If the catheter channel is designed to guide the catheter through the grip body, then the handling of pivoting movements becomes safer and clearer, but the device complexity increases

Engineering Contradiction:

Improvehandling safetyVSAvoidgrip body structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The catheter channel is nested within the grip body as an inner channel, providing guided catheter passage and improved handling safety while minimizing structural complexity through integrated design

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the secondary endoscope is designed with a compact structure for narrow spaces, then the adaptability improves, but the stability of the entire device may be adversely affected

Engineering Contradiction:

Improvenarrow space operationVSAvoiddevice stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The endoscope system is segmented into a mother endoscope and a detachable secondary endoscope, allowing the compact secondary unit to operate in narrow spaces while the complete assembled system maintains stability through the mounting connection

Inventive Principle:

Principle #1Segmentation

AI summary

The invention refers to a secondary endoscope mountable onto a mother endoscope. The secondary endoscope comprises a grip body (4; 400) having an outer body including an inner channel and an inner body (3; 300) arranged in the inner channel of the outer body, said inner body (3; 300) being movable relatively to the outer body; a catheter (5; 500) mounted on the grip body (4; 400); a control element (1; 100) at the proximal side of the grip body (4; 400) for controlling a bending portion (6; 600) arranged on the distal end of the catheter (5; 500), said control element (1; 100) being arranged on the proximal side of the inner body (3; 300); and a mounting connection on the distal end of the grip body (4; 400) for fixing the secondary endoscope to a mother endoscope (200), said mounting connection being attached to the outer body of the grip body (4; 400).
