Hair Grasping Device Trigger Mechanism for Scalp Laceration Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for closing scalp lacerations, such as sutures and staples, are painful and require local anesthetics and follow-up visits, while the hair apposition technique is time-consuming for medical professionals due to difficulty in grasping and pulling clusters of hair across the wound.
Innovation Solution
A hair grasping device with a handle and trigger mechanism that includes grips with arms that can be extended and retracted to capture and hold hair, simplifying the hair apposition technique by facilitating the pulling of hair across a wound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sutures or staples are used to close scalp lacerations, then the wound closure is secure and reliable, but the patient experiences pain and requires local anesthetics and follow-up visits
Solution Approach 1:
The invention extracts and eliminates the harmful elements (sutures, staples, anesthetics, follow-up visits) from the traditional wound closure process by adopting the hair apposition technique, which uses the patient's own hair to close the wound without invasive materials
Solution Approach 2:
The patient's own hair is utilized as the closing mechanism, allowing the body's natural resources to perform the wound closure function without requiring external medical interventions or follow-up removal visits
2Object-affected harmful factors
If the hair apposition technique is used to close scalp lacerations, then no anesthetics or follow-up visits are required, but the procedure becomes difficult and time-consuming for medical professionals
Solution Approach 1:
The patent introduces a specialized grasping device as an intermediary tool between the medical professional and the hair, enabling effective manipulation and positioning of hair clusters across the wound without direct manual handling
Solution Approach 2:
The device segments the hair manipulation function into distinct components (grasping elements, positioning mechanisms) that can independently perform specific tasks, making the overall procedure more controllable and efficient
3Device complexity
If manual hair manipulation is used in the hair apposition technique, then no special equipment is needed, but the procedure is time-consuming and inefficient
Solution Approach 1:
The grasping device incorporates movable and adjustable components that allow dynamic adaptation to different hair types, wound sizes, and manipulation requirements, enhancing procedural efficiency without requiring overly complex equipment

AI summary
A hair grasping device having a handle with hollow fingers, a trigger slidably attached to the handle, a number of grips slidably attached within the hollow fingers connected to the trigger. Each of the grips has a first and a second arm, a central post, and an extended position and retracted position. When in the retracted position, the arms are forced against the central post by the hollow fingers, and when in the extended position, the arms are forced away from the central post, creating a clearance between the arms and the central post.
