Diagnostic Instrument Attachment Assembly for Device Exchange

Solution Overview

Problem

Conventional diagnostic instruments, such as bronchoscopes, do not allow for safe detachment of the proximal end from the penetrating component, making it difficult to exchange secondary devices without fully withdrawing the instrument from the patient's body, leading to prolonged procedures and potential health risks.

Innovation Solution

A medical device assembly with an attachment assembly that enables separation of the proximal end from the penetrating component, allowing for the removal and exchange of secondary devices without retracting the penetrating component, facilitating quick and safe device changes during procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the diagnostic instrument is completely withdrawn from the patient's body to exchange secondary devices, then the exchange can be performed safely, but the procedure duration is prolonged and patient health risks increase

Engineering Contradiction:

Improvesafety of device exchangeVSAvoidprocedure duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The diagnostic instrument is divided into separable components: a proximal end portion and a distal penetrating component. The attachment assembly allows these segments to be detached from each other while the penetrating component remains in the patient's body, enabling secondary device exchange without complete instrument withdrawal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment assembly serves as an intermediary mechanism between the proximal end and the penetrating component. It enables controlled separation and reattachment, facilitating safe secondary device exchange while maintaining the penetrating component's position within the patient's body.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability
