Surgical Threading Device with Removable Suture and Light Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional neck rejuvenation procedures are invasive and often result in complications such as post-operative bleeding, nerve injury, and visible skin deformities due to their complexity and the need for extensive dissection and large incisions, which are not adequately addressed by current methods.
Innovation Solution
A minimally invasive threading device assembly for plastic surgery that includes a threading rod with a translucent light guide and a removable suture assembly, allowing for precise placement of sutures through small access sites without extensive skin dissection, using a technique called Percutaneous Trampoline Platysmaplasty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional neck rejuvenation procedures are performed with extensive dissection and large incisions, then adequate support and tension restoration can be achieved, but post-operative bleeding, nerve injury, and visible skin deformities occur
Solution Approach 1:
The procedure segments the surgical approach into multiple small access sites instead of one large incision, allowing sutures to be placed at specific anatomical locations while minimizing tissue disruption and visible scarring
Solution Approach 2:
A threading device with light guide serves as an intermediary tool to deliver sutures through small access sites to the deeper anatomical structures, enabling precise suture placement without extensive dissection
2Object-affected harmful factors
If minimally invasive techniques with small access sites are used, then trauma and scarring are minimized, but precise placement of support structures becomes more difficult
Solution Approach 1:
The threading device acts as an intermediary instrument that bridges the gap between small external access sites and deep anatomical targets, enabling precise suture placement through the restricted access provided by minimal incisions
Solution Approach 2:
The light guide attached to the threading rod provides visual illumination and contrast enhancement, allowing the surgeon to precisely track the position of the threading device and suture placement in real-time through the small access sites
3Adaptability or versatility
If removable suture assemblies are used instead of permanent attachments, then flexibility and adaptability during the procedure are improved, but device complexity increases
Solution Approach 1:
The suture assembly is segmented into separable components (suture material, cuff, and threading rod), allowing the surgeon to select and attach different suture types to the same threading device based on specific anatomical requirements
Solution Approach 2:
The threading device is designed with universal features including a standardized cuff attachment mechanism and light guide interface, enabling it to work with multiple suture types and configurations for different anatomical applications
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach minimizes trauma and scarring by allowing for the placement of a support matrix without large incisions, providing a natural-looking structure and reducing the risk of complications associated with traditional necklift procedures.
Implementation Method 1
a translucent light guide extending through the elongated tube. The light guide allows light to be transmitted through the material comprising the light guide from one end of the tube to the other

AI summary
A threading device assembly for use in plastic surgery that includes a threading rod and a removable suture assembly secured to the threading rod. The threading rod includes an elongated tube with first and second opposite ends and a reduced diameter portion defined therein, and a translucent light guide extending through the elongated tube. The light guide allows light to be transmitted through the material comprising the light guide from one end of the tube to the other. The removable suture assembly includes a cuff positioned in and at least partially around the reduced diameter portion of the elongated tube, and a suture secured to the cuff.
