Solution Overview

Problem

Existing methods for mounting a cutting thread on biological tissues to treat conditions like carpal tunnel syndrome and trigger finger syndrome cause damage to surrounding tissues due to repeated exposure and insertion of the thread through the skin.

Innovation Solution

A needle unit utilizing magnetic forces to connect two needles, forming a loop for the cutting thread, minimizing external exposure and reducing tissue damage by using a first and second needle with magnetic members or metal materials to maintain communication through magnetic or metal coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cutting thread is repeatedly inserted and exposed through the skin using conventional needles, then the cutting thread can be mounted on the biological tissue, but the surrounding soft tissue is damaged

Engineering Contradiction:
Improvethread mounting capabilityVSAvoidtissue damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent combines two separate needle insertion operations into a single integrated procedure. The first needle and second needle are both inserted simultaneously, and the cutting thread is passed through both needles in one continuous motion, eliminating the need to expose and re-insert the thread multiple times. This merging of operations reduces the number of times the cutting thread penetrates the skin and minimizes repeated trauma to the surrounding soft tissue.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a guide structure or tunnel formed by the first needle that serves as an intermediary pathway. The cutting thread is passed through this pre-formed pathway rather than being repeatedly inserted through the skin surface. The guide structure acts as a mediator that protects the surrounding tissue by providing a defined route for the cutting thread, reducing collateral damage to soft tissues during the mounting process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If multiple separate needle insertions are performed to mount the cutting thread, then the thread can be positioned correctly, but the procedure time is extended

Engineering Contradiction:
Improvethread positioning accuracyVSAvoidprocedure duration
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges multiple sequential needle insertion steps into a single coordinated operation. Both the first needle and second needle are inserted simultaneously, and the cutting thread is passed through both in one continuous motion. This combines what would traditionally be separate time-consuming steps into a single efficient procedure, reducing overall procedure time while maintaining the precision of thread positioning through the coordinated geometry of the dual-needle system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary positioning of the first needle to create a guide pathway before passing the cutting thread through. This preliminary action establishes the correct trajectory and positioning, allowing the subsequent thread passage to be completed quickly and accurately without requiring multiple adjustment attempts, thereby reducing overall procedure time while maintaining positioning precision.

Inventive Principle:
Principle #10Preliminary action
