Suturing Needle with Grooves for Gold Thread Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suturing needles for injecting gold threads into the scalp for hair loss treatment face challenges such as high manufacturing costs due to the need for intricate hollow needle designs and difficulty in inserting gold threads, and require complex procedures involving multiple needles and knots.
Innovation Solution
A suturing needle design featuring a sharpened tip with an upper groove to hold the gold thread and a lower groove near the handle, allowing the gold thread to be hooked and easily injected without the need for a hollow needle, enabling simpler manufacturing and simultaneous injection of multiple threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hollow needle design is used to inject gold thread, then the gold thread can be inserted through the needle, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The invention extracts the gold thread from the hollow needle design and uses external grooves on the needle surface to hold and guide the thread instead. This eliminates the need for complex hollow needle manufacturing while achieving the same thread injection function through simpler external groove structures.
Solution Approach 2:
Instead of placing the thread inside the hollow needle (internal structure), the invention inverts the approach by placing grooves on the external surface of the needle to hold the thread. This inversion simplifies manufacturing while maintaining the thread injection capability.
2Ease of operation
If a conventional injection kit with thin absorbable suture thread is used, then the procedure is simplified, but the thread breaks easily due to sharp needle tip and provides insufficient self-healing substance generation
Solution Approach 1:
The invention uses a composite structure combining a sharp needle tip for easy penetration with external grooves that protect and guide the gold thread during injection. This composite design maintains procedural simplicity while preventing thread breakage through the protective groove structure.
3Reliability
If multiple needles and knots are used for gold thread injection, then the thread can be securely injected, but the treatment procedure becomes complex and time-consuming
Solution Approach 1:
The invention merges the functions of multiple needles and knot-tying procedures into a single needle with integrated grooves. The grooves themselves provide the retention function that previously required multiple needles and knots, simplifying the overall procedure while maintaining secure thread placement.
Solution Approach 2:
The grooves on the needle surface automatically hold and guide the gold thread during injection without requiring additional knots or multiple needles. The structure serves its own retention function, eliminating the need for complex multi-step procedures.
