Solution Overview

Problem

Current bronchoscope adapters fail to maintain precise positioning of the bronchoscope during electromagnetic navigational bronchoscopy due to patient and operator respiration, leading to displacement of the extended working channel tip from the intended target, necessitating additional personnel to stabilize the bronchoscope, which increases operational complexity and reduces precision.

Innovation Solution

A bronchoscope adapter with a reversibly adjustable inner diameter bronchoscope access port and an elastomeric locking mechanism that allows single-operator control and secure locking of the bronchoscope to the endotracheal tube, maintaining precision and reducing the need for additional personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed inner diameter bronchoscope access port is used in the adapter, then the adapter structure is simple, but it cannot accommodate bronchoscopes of different sizes and cannot maintain precise positioning during respiration

Engineering Contradiction:
Improveaccommodation of different bronchoscope sizesVSAvoidadapter structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bronchoscope access port incorporates a collapsible inner diameter component that can dynamically adjust its size. This component includes a collapsible portion with flexible walls that can be compressed to reduce the inner diameter for securing smaller bronchoscopes, and expanded to accommodate larger bronchoscopes. The dynamic adjustment mechanism allows the adapter to adapt to different bronchoscope sizes without requiring multiple fixed-sized adapters, thereby improving versatility while maintaining relatively simple structure through a single adjustable component design.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If additional personnel are added to stabilize the bronchoscope, then positioning precision is improved, but operational complexity and cost increase

Engineering Contradiction:
Improvebronchoscope positioning precisionVSAvoidoperational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The adapter incorporates a self-locking mechanism that automatically secures the bronchoscope in place without requiring additional personnel. The collapsible inner diameter component can be compressed by the bronchoscopist's own hand to lock the bronchoscope securely in the desired position. This self-service locking mechanism eliminates the need for extra staff members to manually stabilize the bronchoscope, thereby maintaining high positioning precision while reducing operational complexity and allowing a single operator to perform the procedure independently.

Inventive Principle:
Principle #25Self-service

3Reliability

If the bronchoscope is not securely locked, then the adapter structure is simple, but the extended working channel tip displaces from the intended target due to respiration

Engineering Contradiction:
Improvebronchoscope positioning stabilityVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism utilizes changes in the physical state of a collapsible component. When the inner diameter component is compressed, its volume decreases and its walls flex inward, creating a tight seal that locks the bronchoscope securely. When expanded, it allows easy insertion and removal. This parameter change-based locking mechanism provides reliable positioning stability to prevent displacement during respiration while keeping the locking mechanism itself relatively simple, avoiding the need for complex mechanical locks or additional stabilization devices.

Inventive Principle:
Principle #35Parameter changes
