Surgical Threading Device Minimally Invasive Neck Lift
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 scarring, as they fail to adequately address the loss of tension and support in the neck area due to aging, leading to suboptimal outcomes.
Innovation Solution
A minimally invasive technique using a threading device with a suture permanently attached to an elongated rod, which is inserted through small access sites in the skin to form a suture matrix under the skin, providing support without the need for large incisions or extensive dissection, and a lancet for precise puncture creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional neck rejuvenation procedures are used, then the loss of tension and support in the neck area is addressed, but the procedures result in post-operative bleeding, nerve injury, and visible scarring
Solution Approach 1:
The procedure segments the traditional single large incision approach into multiple small puncture sites. The threading device is inserted through several small access sites in the skin rather than one large incision, allowing the suture to be placed subplatysmally while minimizing trauma and scarring at each individual site.
Solution Approach 2:
The threading device serves as an intermediary tool that delivers the suture material through the skin and subcutaneous tissue without requiring direct surgical exposure. The device guides the suture through the platysmal muscle and underlying structures, reducing the need for extensive dissection and minimizing damage to nerves and blood vessels.
2Reliability
If conventional necklift procedures with extensive dissection are performed, then adequate support and tension restoration is achieved, but the trauma and scarring are significant
Solution Approach 1:
The procedure uses multiple small puncture sites distributed across the neck area rather than one large incision. Each puncture site creates minimal trauma and scarring, while collectively they provide adequate access for placing the suture to restore support and tension throughout the neck region.
Solution Approach 2:
The threading device and suture placement technique provides localized precision in the subplatysmal plane without requiring widespread dissection. The suture can be positioned specifically where support is needed beneath the platysmal muscle, achieving effective support restoration with minimal overall tissue disruption.
3Object-affected harmful factors
If minimally invasive threading technique is used, then trauma and scarring are reduced, but the ability to provide adequate support and tension may be compromised
Solution Approach 1:
Multiple small puncture sites are strategically positioned to allow the suture to traverse the entire subplatysmal space. This segmented access approach maintains the minimally invasive benefit of reduced trauma and scarring while ensuring the suture can provide adequate support across the full treatment area.
Solution Approach 2:
The threading device transitions from a two-dimensional surface approach to a three-dimensional subplatysmal pathway. By threading the suture through the depth of the tissue planes beneath the platysmal muscle, the procedure achieves adequate support restoration without requiring extensive surface dissection, thus maintaining minimal trauma and scarring.

AI summary
A threading device assembly for use in plastic surgery that includes a first elongated rod having first and second opposite ends, a second elongated rod having first and second opposite ends, and a suture having first and second opposite ends. The first end of the suture is secured to the first elongated rod at a location that is approximately halfway between the first and second ends, and the second end of the suture is secured to the second elongated rod at a location that is approximately halfway between the first and second ends.
