Organopexy Tool Locking Part Suture Thread Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional organopexy tool sets require cumbersome and skill-intensive operations for inserting and removing suturing threads, with poor reliability due to simultaneous needle insertion and limited space for thread catching, leading to difficulties in affixing organs to body walls.
Innovation Solution
An organopexy tool with a locking part and elastic telescoping member, where the suture thread is attached halfway along the axial surface, allowing for simple and reliable affixation by forming a T shape with the locking part and suture thread, facilitating easy insertion and removal through a puncture needle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two puncture needles are inserted simultaneously with an internal needle and suture thread passed through, then organopexy can be performed, but the operation becomes cumbersome and difficult requiring much skill
Solution Approach 1:
The suture thread is pre-attached to the locking part at a mid-point position before insertion. This preliminary configuration ensures that when the locking part is inserted through the puncture needle, the suture thread is already positioned to be caught by the loop, eliminating the need for complex manual threading operations during the procedure.
Solution Approach 2:
The locking part serves as an intermediary component between the puncture needle and the suture thread. It provides a structured interface with a mid-point attachment that guides the suture thread through the needle and into the loop, simplifying the interaction between these components and improving operational ease.
2Reliability
If the internal needle is not properly inserted into the puncture needle, then the loop protrusion direction or shape becomes incorrect, but this requires precise skill to avoid
Solution Approach 1:
The locking part has a specific local quality with the suture thread attached at a mid-point position. This localized attachment point ensures that when the locking part is inserted, the suture thread naturally protrudes in the correct direction and shape, providing built-in guidance that reduces the skill level required for proper insertion.
3Reliability
If there is insufficient space on the inside of the sutured part, then it is difficult to catch and hold the suture thread with the loop, but this is necessary for proper affixation
Solution Approach 1:
The suture thread is pre-positioned on the locking part before insertion, so that when the loop is formed, the thread is already in the correct position to be caught. This eliminates the need for additional space within the sutured part for manual thread manipulation, as the thread positioning is accomplished during the insertion phase.
Solution Approach 2:
The invention replaces the manual mechanical manipulation of threading and catching with a pre-configured system where the suture thread is attached to the locking part. This substitution reduces the need for complex manual dexterity and sufficient internal space for thread manipulation.
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
The organopexy tool set enables simple and reliable affixation of organs to body walls with improved operating efficiency, reducing the complexity and skill required for practitioners, and ensuring secure attachment and easy removal.
Implementation Method 1
The practitioner pulls the suture thread from the portion at the other end of the rod-shaped part. The pulling force causes the elastic telescoping member to contract, and when the pulling force is released, the elastic telescoping member extends to substantially its original length.

AI summary
The present invention provides an organopexy tool (10, 40) comprising a locking part (11, 41) and suture thread (12, 42). Locking part (11, 41) is made of a rod-shaped part (13, 14), and the coil spring (14) that covers the rod-shaped part (13, 43) and is affixed to one end (13a, 43a) of rod-shaped part (13, 43), and suture thread (12, 42) is connected to the middle of rod-shaped part (13, 43) through the inside of coil spring (14) from one end (13b, 43b) of rod-shaped part (13, 43). Insertion tool (20, 50) has a puncture needle (21) for insertion that can house the locking part (11, 41) and a tubular push-out part (22) that is inserted into puncture needle (21) to push locking part (11, 41) out of the tip (25).
