Auxiliary Device for Puncture Needle Alignment and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical suturing devices with plural puncture needles face difficulties in maintaining proper positional alignment during the suturing process, leading to instability and complexity in needle manipulation.
Innovation Solution
An auxiliary device featuring parallel guide grooves and a rotating-sliding contact part allows for easier alignment and stabilization of puncture needles, preventing displacement during the suturing process by ensuring they remain within the guide grooves while being rotated and slid along the auxiliary device's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two puncture needles are fixed to the connecting plate and insertion length adjusting plate, then the puncture needles can be simultaneously positioned, but the positional relationship cannot be corrected in midstream making manipulation difficult
Solution Approach 1:
The puncture needles are made movable relative to the connecting plate through sliding grooves, allowing the needles to be dynamically adjusted during the puncture process. This enables correction of positional relationships in midstream while maintaining precise alignment through the guide grooves, resolving the contradiction between fixed positioning precision and manipulative flexibility
2Stability of the object's composition
If the puncture needles are fixed in position, then the positional relationship is stable, but the manipulation complexity increases when adjustment is needed
Solution Approach 1:
The connecting plate with sliding grooves acts as an intermediary mechanism between the puncture needles and the insertion length adjusting plate. This intermediary structure provides both stability through the guide grooves that maintain positional relationships and flexibility through the sliding mechanism that allows adjustment, thereby reducing manipulation complexity while preserving stability

AI summary
An auxiliary device for a puncture needle allowing an easier manipulation of puncture needles as well as being capable of improving the suture stability. The auxiliary device for a puncture needle comprises a plate-shaped auxiliary device main body on the surface of which parallel guide grooves were formed, and a plate-shaped rotating-sliding contact part rotatably attached to one of the edge parts of the auxiliary device main body. Moreover, a stabilization plate was provided at the lower end part of the auxiliary device main body. And, a window part for confirming an insertion-puncture needle-outer needle and a pullout-puncture needle were provided at the lower part side portion of the auxiliary device main body. Moreover, a projecting edge part was formed at the upper end part of the auxiliary device main body, and an opening side width of a portion located at the projecting edge part of the guide grooves was made wider than the width of the other portion of the guide grooves.
