Surgical Thread Insertion Apparatus with Integrated Fixation Anchor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lift surgery using medical threads is time-consuming and requires multiple incisions, posing a high risk due to the need for multiple through-holes and high anesthesia levels.
Innovation Solution
A medical thread insertion apparatus with a hollow pipe and support rod forming an insertion path, a tapered inclined insertion unit, and a medical thread supply unit with a loop-shaped support and barbs, allowing for easy insertion and fixation of the thread with reduced tissue damage and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple through-holes are formed for inserting and fixing the medical thread, then the medical thread can be inserted and fixed into the body, but the number of incisions increases and tissue damage worsens
Solution Approach 1:
The patent combines the insertion function and fixation function into a single integrated device. The needle assembly includes both the insertion needle and the fixation anchor, allowing both functions to be performed through one through-hole rather than requiring separate insertion and fixation holes. This merging of functions reduces the number of incisions and minimizes tissue damage.
Solution Approach 2:
The medical thread insertion device is designed with multi-functionality, serving both as an insertion tool and a fixation tool. The needle can insert the thread while the integrated anchor provides fixation, making the device universal for both insertion and fixation tasks through a single through-hole.
2Reliability
If the medical thread is inserted through multiple through-holes and requires knotting, then the thread can be secured, but the surgical procedure becomes time-consuming
Solution Approach 1:
The fixation anchor is pre-formed and integrated onto the needle before the surgical procedure begins. The anchor is prepared in advance on the needle, so that when the needle is inserted through the tissue, the anchor is already positioned and ready to deploy immediately upon insertion, eliminating the need for time-consuming knotting operations during surgery.
Solution Approach 2:
The patent extracts the knotting operation from the surgical procedure by replacing it with a pre-formed anchor that provides fixation without requiring manual knotting. The anchor's structure is designed to provide mechanical fixation automatically upon deployment, removing the time-consuming step of tying knots during the surgical procedure.
3Reliability
If multiple through-holes are formed for thread insertion and fixation, then the thread can be secured, but the surgical risk increases due to higher anesthesia requirements
Solution Approach 1:
The patent merges the insertion and fixation operations into a single through-hole, reducing the total number of incisions required. This reduction in the number of through-holes decreases the overall surgical intervention, thereby lowering anesthesia requirements and reducing surgical risk.
Solution Approach 2:
The invention changes the fundamental parameter of the number of through-holes from multiple to single. By designing a system that achieves both insertion and fixation through one hole, the surgical parameters are optimized to minimize tissue trauma, reduce anesthesia needs, and lower overall surgical risk.

AI summary
A medical thread insertion surgery kit includes an insertion path forming unit which includes a pipe member comprising a pipe that is hollow and forms a path through which a medical thread is to be inserted and a support member comprising a support rod that is inserted into the pipe of the pipe member and has stiffness greater than stiffness of the pipe member; a medical thread supply unit which supplies a medical thread through the pipe member after the support member is removed from the insertion path forming unit; and a push unit that is slidable in the pipe of the pipe member and pushes the medical thread through the pipe of the pipe member.
