Medical Thread Insertion Instrument Using Intermediary Needle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical threads cause damage and side effects when inserted into skin tissue due to direct contact with barbs and contamination, and removal can be difficult, leading to prolonged recovery and potential tissue damage.
Innovation Solution
A medical thread insertion instrument that uses a needle and tube system to minimize direct contact between the medical thread and skin tissue, with the medical thread embedded in the needle and inserted into the skin, and biomaterials injected to enhance engraftment and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the medical thread is inserted directly into the skin tissue with barbs exposed, then the pulling force and fixation strength are improved, but the skin tissue damage and contamination risk increase
Solution Approach 1:
The patent introduces a needle as an intermediary carrier that holds the medical thread with barbs during insertion. The needle protects the barbs from direct contact with skin tissue during the insertion process, preventing tissue damage while maintaining the barbs' fixation capability. After insertion, the needle is removed and the barbs engage with the tissue to provide the required pulling force.
2Adaptability or versatility
If the medical thread is exposed to outside for a long time, then the treatment flexibility is improved, but the contamination risk increases
Solution Approach 1:
The patent prepares the medical thread with barbs in advance and loads it onto the needle before the treatment procedure. This preliminary preparation allows the thread to be protected from contamination during storage and transport, while still enabling flexible treatment planning. The pre-loaded needle can be quickly inserted when needed, maintaining treatment flexibility without exposing the thread to contamination risks.
3Strength
If the barbs are made more prominent to improve pulling force, then the fixation strength is improved, but the skin tissue damage during insertion increases
Solution Approach 1:
The needle serves as a protective intermediary that allows prominent barbs to be transported and inserted without causing tissue damage. The barbs are confined within or on the needle during insertion, preventing them from tearing the skin. Only after the needle is in position and removed do the barbs engage with the tissue to provide the enhanced pulling force needed for fixation.
4Productivity
If the medical thread is removed after treatment, then the treatment completion is achieved, but the skin tissue damage and recovery time increase
Solution Approach 1:
The patent employs a disposable needle that is used only for the insertion process and then discarded. This eliminates the need to remove the needle afterward, avoiding the tissue damage and recovery issues associated with removing foreign objects from the skin. The medical thread with barbs remains in the tissue to provide ongoing fixation, while the needle's temporary role is fulfilled and it is discarded.

AI summary
The present invention relates to a medical thread insertion instrument capable of easily inserting a medical thread into a human body and, more particularly, relates to a medical thread insertion instrument and a medical thread insertion method using the same, wherein the instrument guides an insertion of the medical thread so as to smoothly insert the medical thread into a skin tissue of the human body; may minimize the risk of side effects by pulling the medical thread out of the skin tissue even in the case where the insertion instrument is removed; and may inject bio injectable material between the skin tissue and the medical thread in order to provide smooth recovery of damaged skin tissue due to the insertion of the insertion instrument.
