Adjustable Headband for Craniofacial Puncture Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for craniofacial punctures face challenges in precision, stability, and safety due to manual operation, irregular facial anatomy, and the need for screw-based attachment, which can lead to tissue damage and limited mobility.
Innovation Solution
A device with an adjustable headband and variable diameter ring system that securely attaches to the craniofacial area without screws, allowing for precise needle placement and adjustable angles, enabling safe and effective punctures by adapting to individual anatomy and providing a graduated working area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based attachment mechanisms are used to secure the device to the craniofacial area, then the device stability and fixation reliability are improved, but the risk of tissue damage and harm to the user increases
Solution Approach 1:
The device replaces screw-based attachment with a headband (1) that has adjustable ties (1b) and fastening mechanisms that secure to the craniofacial area without penetrating or damaging tissue. The headband provides stable fixation through circumferential support rather than puncture fixation
2Manufacturing precision
If the device is designed with fixed geometric parameters to ensure manufacturing precision, then the manufacturing quality is improved, but the adaptability to irregular facial anatomy deteriorates
Solution Approach 1:
The device incorporates a variable diameter ring (3) connected to the headband that can be adjusted to different diameters using mechanisms such as expansion joints or telescoping sections. This allows the same manufactured component to fit multiple facial geometries by changing its effective size rather than requiring custom-manufactured parts for each patient
3Ease of operation
If the device allows free movement of the needle carrier to provide operational flexibility, then the ease of operation is improved, but the positioning precision and stability deteriorates
Solution Approach 1:
The needle carrier (4) is connected to the variable diameter ring (3) through a mechanism that allows movement and repositioning. The carrier can be moved to access different target structures, then secured in the desired position using fastening mechanisms that maintain precise positioning during the punction procedure

AI summary
The present invention is for use in the field of instruments and devices adapted for surgery and diagnostics with instruments. Specifically, it relates to a device for enabling the punction of particular anatomical structures in the craniofacial area. The device comprises a support frame in the form of an adjustable headband which may be adapted to the user's anatomy, a sphere with two arms that hold a placement fastener onto the face or cranium of the user, applying pressure to a specific position through the use of screws or rings that allow free movement on the hinges of the arms.
