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 for forming an insertion path, a tapered inclined insertion unit, and a medical thread supply unit with a loop-shaped support to facilitate easy insertion and fixation of the thread with reduced tissue damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple through-holes are formed for thread insertion and fixation, then the medical thread can be properly inserted and fixed, but the surgery time increases and the risk level increases due to high anesthesia requirements

Engineering Contradiction:

Improvethread fixation reliabilityVSAvoidsurgery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the insertion function and fixation function into a single integrated needle structure. The needle includes an insertion portion for penetrating tissue and a fixation portion with expansion elements that deploy after insertion, allowing both thread insertion and secure fixation to occur through one through-hole rather than requiring separate insertion and fixation holes.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The needle is divided into functionally distinct segments: an insertion portion for penetrating the tissue barrier, a body portion for guiding the thread, and a fixation portion with expansion elements (such as barbs or anchors) that deploy after insertion to secure the thread. This segmentation allows each portion to be optimized for its specific function while working together as an integrated system.

Inventive Principle:

Principle #1Segmentation

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.
