Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detachment of the distal end cap from the distal-end-portion body of an endoscope can cause damage or apply a load to the endoscope, posing a risk during the washing process.
Innovation Solution
A distal-end-cap detachment jig with an inclined surface that deforms the distal end cap to expand its inner space, facilitating safe detachment, and includes features like a connection portion with a finger hole and a housing member to stabilize and guide the detachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a jig is used to detach the distal end cap, then the distal end cap can be removed after treatment, but damage or load may be applied to the endoscope
Solution Approach 1:
The detachment jig acts as an intermediary tool between the operator and the distal end cap. The jig includes a body portion with an inclined surface that inserts into the distal end cap's inner space and deforms it to expand the space, allowing safe detachment without directly applying harmful forces to the endoscope. The inclined surface serves as a mediator that gradually expands the inner space through controlled deformation.
Solution Approach 2:
The detachment jig performs preliminary action by inserting its body portion into the distal end cap before detachment occurs. The inclined surface pre-deforms the distal end cap to expand the inner space, creating a buffer zone that prevents direct impact and harmful forces during the subsequent detachment process.
2Ease of manufacture
If the distal end cap is detached to improve washability, then cleaning access is improved, but the endoscope may be damaged during detachment
Solution Approach 1:
The detachment jig serves as a protective intermediary that enables washability improvement while protecting endoscope integrity. The inclined surface of the jig body portion deforms the distal end cap in a controlled manner, expanding the inner space to facilitate detachment without transmitting damaging forces to the endoscope structure.
Solution Approach 2:
The detachment jig provides beforehand cushioning by pre-deforming the distal end cap through the inclined surface before actual detachment occurs. This pre-action creates a buffer zone that absorbs and distributes forces, preventing sudden impacts or harmful loads from reaching the endoscope during the detachment process.

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 jig effectively suppresses damage and load on the endoscope, enabling easy and safe removal of the distal end cap without causing harm to the device.
Implementation Method 1
the inclined surface deforms the distal end cap in a direction of expanding the inner space of the distal end cap

AI summary
Provided is a distal-end-cap detachment jig capable of safely detaching a distal end cap from a distal-end-portion body.A distal-end-cap detachment jig that is used to detach a distal end cap mounted on a distal end of a side-viewing scope and having an inner space which communicates with a cap opening allowing a passage of a treatment tool, includes at least a body portion that has an inclined surface, in which the inclined surface is tapered in a direction of insertion into the inner space of the distal end cap, and in a case where the body portion is inserted into the inner space of the distal end cap, the inclined surface deforms the distal end cap in a direction of expanding the inner space of the distal end cap.
