Endoscope Connector Detachment to Prevent Single-Use Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in preventing the reuse of single-use endoscopes against the manufacturer's intention, as existing technologies do not effectively prevent reconnection of the endoscope's connector to a processor after use.
Innovation Solution
A connector unit design that includes a first and second connector, where the first connector is snap-fitted to the second connector using an elastic member, and a detachment jig is used to electrically disconnect the wires, ensuring the endoscope cannot be reused by mechanically and electrically disconnecting the connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-use endoscope connector is designed to be easily connected to a processor, then ease of operation is improved, but the risk of unintended reuse increases
Solution Approach 1:
The wire disconnection action is performed in advance during the detachment process. When the first connector is detached from the second connector, the first wire is automatically disconnected from the second wire before the connectors can be reconnected. This preliminary disconnection prevents any subsequent reuse attempts, as the electrical connection is already broken.
Solution Approach 2:
The connector system is divided into two separate connectors (first connector and second connector) that can be detached from each other. This segmentation allows the endoscope to be easily disconnected from the processor, and the automatic wire disconnection further divides the electrical connection into separable components that cannot be easily reconnected.
2Reliability
If the connector is designed to prevent reuse by permanent disconnection, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The connector system transitions from a static permanent connection to a dynamic detachable connection. The first connector can be easily attached to and detached from the second connector through simple engagement and disengagement actions. The wire disconnection is dynamically triggered by the detachment motion, providing both ease of operation and prevention of reuse.
3Adaptability or versatility
If a relay adapter is used to connect reusable and single-use endoscopes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The second connector is designed as a universal interface that can accommodate both reusable endoscope connectors and single-use endoscope connectors. This multi-functional design allows the same processor setup to work with different endoscope types without requiring separate relay adapters for each type, reducing overall system complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents the reuse of single-use endoscopes by ensuring the connectors cannot be reconnected, maintaining the intended single-use nature and allowing for easy disassembly for replacement or reuse of parts.
Implementation Method 1
the first connector includes an elastic member configured to store energy when deformed

AI summary
A method of operating a connector unit of an endoscope system, the method including engaging a first engagement portion of a first connector with a second engagement portion of a second connector to electrically connect a first wire to a third wire via a second wire, electrically disconnecting the first wire and the second wire, and detaching the first engagement portion from the second engagement portion. The first connector includes the first wire electrically connected to the second wire. The second connector includes the third wire.
