Rotating Paddle Suture Securement Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing sutures external to the patient's body during medical procedures often lose integrity over time or under force, can be uncomfortable, and are difficult for medical personnel to handle and manipulate.
Innovation Solution
A suture securement system comprising a base paddle and a rotating paddle with an extension arm, which crimps and optionally clamps the suture to secure it, using mechanisms like ratcheting and detents to maintain tension and prevent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tying or crimping methods are used to secure suture material, then the suture can be secured external to the body, but the arrangement loses integrity over time or upon application of force
Solution Approach 1:
The device employs a dynamic crimping mechanism where a first paddle and second paddle can be moved relative to each other along a longitudinal axis. The second paddle is selectively movable from an initial position to a crimping position, allowing the application of controlled force to crimp the suture material between the paddles. This dynamic action creates a secure, permanent deformation that maintains integrity over time.
2Reliability
If traditional crimping or clamping arrangements are used, then the suture can be secured, but the arrangement is difficult for medical personnel to handle and manipulate
Solution Approach 1:
The device transitions from a linear manipulation approach to a rotational approach. The second paddle is configured to rotate about the longitudinal axis, allowing medical personnel to crimp the suture by simply rotating the paddle rather than applying complex manual forces. This rotational motion along the longitudinal axis significantly improves ease of operation while maintaining securement reliability.
3Reliability
If traditional suture securing methods are used, then the suture can be anchored, but the arrangement creates undesirable effects at the point of contact with the patient's skin and is uncomfortable
Solution Approach 1:
The paddles are configured with smooth, rounded surfaces that distribute pressure evenly across the suture material and patient's skin. The first paddle and second paddle create a gentle crimping action rather than sharp compression, reducing localized stress on the skin. This design maintains secure anchoring while minimizing discomfort and harmful effects at the contact point.
4Reliability
If a crimping mechanism is added to improve securement, then suture integrity is improved, but the device complexity increases
Solution Approach 1:
The device is segmented into distinct functional components: a first paddle for initial suture placement, a second paddle for crimping, and a longitudinal axis defining the direction of force application. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure simple and manageable, avoiding unnecessary complexity.
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
The system effectively maintains suture tension, reduces discomfort for patients, and simplifies handling for medical personnel by providing a secure and reliable method to crimp and clamp sutures along tortuous paths.

AI summary
Described are devices, methods and systems for securing sutures external to the body. In certain aspects, a suture securement device includes a base paddle defining a slot and a suture aperture in communication with the slot, and a rotating paddle having an extension arm with a suture aperture. In such embodiments, the extension arm can rotate within the slot to frictionally crimp a suture, such that the suture is substantially prevented from moving with the apertures.
