Solution Overview

Problem

Conventional endoscopes require two operators to perform procedures due to the need for separate handling of the endoscope and auxiliary tools, making these procedures inefficient and costly.

Innovation Solution

An endoscopic system with a clip that securely attaches the handle of an auxiliary tool to the endoscope, featuring a planar base and flexible retaining arms with elastomeric material for secure retention, allowing single-operator use by eliminating the need for a second operator to manage the auxiliary tool.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional endoscopes are used with separate handling of endoscope and auxiliary tools, then the endoscope can be operated with basic functionality, but two operators are required making procedures inefficient and costly

Engineering Contradiction:
Improveprocedure efficiencyVSAvoidoperator requirement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent combines the endoscope and auxiliary tool handles into a single integrated assembly using a clip mechanism. The clip securely attaches the auxiliary tool handle to the endoscope handle, allowing one operator to control both devices simultaneously. This merging of previously separate handling requirements directly resolves the contradiction by enabling single-operator use while maintaining full functionality of both the endoscope and auxiliary tools.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a clip mechanism is added to attach auxiliary tools to the endoscope, then single-operator use becomes possible, but the device complexity increases

Engineering Contradiction:
Improveoperator requirementVSAvoidclip mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The clip acts as an intermediary component that bridges the endoscope handle and auxiliary tool handle. Rather than integrating the two handles directly into a complex unified structure, the clip provides a simple, removable connection mechanism. This intermediary approach allows the handles to remain relatively simple in design while still achieving the goal of single-operator control, thus minimizing the increase in overall device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the clip allows quick attachment and detachment of auxiliary tools, then versatility is improved, but the securing reliability may be compromised

Engineering Contradiction:
Improvetool attachment flexibilityVSAvoidattachment security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The clip mechanism incorporates dynamic elements such as spring-loaded arms and movable clamping surfaces that automatically adjust to secure the auxiliary tool handle. The spring arms can flex during attachment and detachment operations, then maintain constant securing force during use. This dynamic design allows the clip to provide both quick attachment/detachment capability and reliable securing force simultaneously, resolving the contradiction between versatility and reliability.

Inventive Principle:
Principle #15Dynamics

AI summary

An endoscopic system may include an endoscope including a proximal end, a distal end, and an elongated sheath extending therebetween. The elongated sheath may define at least one lumen. The proximal end of the endoscope may include a handle operably coupled to a proximal portion of the elongated sheath. The endoscopic system also may include a clip coupled to the handle of the endoscope. The clip may include at least one retaining arm configured to receive a handle of an auxiliary tool. The at least one lumen may be configured to receive a distal portion of the auxiliary tool. Associated devices and methods are also disclosed.
