Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing titanium clips used in endoscopic surgery are undetachable or difficult to remove, leading to discomfort, tissue damage, and secondary injuries during removal.
Innovation Solution
A detachable titanium clip assembly comprising a titanium clip body with elastically deformable connecting rods and a fragile portion, a cylindrical sleeve with a circular step, and a clip implanting and withdrawing device that allows for easy implantation and detachment of the clip using an endoscope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If titanium clips are made detachable with a breaking structure, then ease of removal is improved, but device complexity increases
Solution Approach 1:
The titanium clip is divided into a clip body and a detachable wire portion. The wire portion includes a breaking structure that can be separated from the clip body through a specific operation sequence, allowing the clip to be removed while leaving the breaking structure behind. This segmentation enables easy removal without requiring complex detachment mechanisms.
Solution Approach 2:
The wire portion is extracted as a separate, removable component from the clip body. By designing the wire with a breaking structure that can be detached through controlled breaking, the patent allows the main clip body to remain in place while the wire portion is removed, simplifying the removal process without adding complex mechanisms.
2Ease of operation
If titanium clips are removed by pulling, then removal capability is achieved, but harmful effects increase due to tissue damage
Solution Approach 1:
The patent converts the harmful effect of direct pulling into a beneficial controlled breaking process. The wire portion is designed with a breaking structure that allows it to break at a predetermined location during removal, transforming the potentially harmful pulling force into a controlled breaking action that minimizes tissue damage while achieving removal capability.
3Ease of operation
If titanium clips are made detachable with breaking structures, then ease of removal is improved, but reliability decreases due to potential failure
Solution Approach 1:
The wire portion is pre-designed with a breaking structure that determines a predetermined breaking location. This preliminary design ensures that during the removal process, the wire will break at the intended location rather than failing unexpectedly, thereby maintaining reliability while enabling easy removal through controlled breaking.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy implantation and direct detachment of titanium clips without causing secondary injuries, maintaining the clipping structure of conventional titanium clips and ensuring effective hemostasis.
Implementation Method 1
one ends of elastically deformable connecting rods are arranged at tails of the first clip arms, the other ends of the connecting rods are integrated to form a connecting end, and a fragile portion to be snapped under an external force is arranged at the connecting end
