Syringe Tripod Attachment for Tissue Retraction and Injection Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Administration of anesthetic injections is challenging due to tissue mobility, restricted visibility, and patient discomfort, which compromises effectiveness and increases anxiety, making the procedure difficult for practitioners.
Innovation Solution
A tripod attachment for a syringe featuring a ring-shaped base, pivotably connected upright supports, and a flexible loop that stabilizes the injection site by applying uniform pressure with pressure pads, enhancing injection accuracy and reducing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tissue retraction is used, then injection can be administered, but tissue mobility and restricted visibility worsen the procedure
Solution Approach 1:
The device segments the injection system into distinct functional components: a stable base portion that anchors to the syringe, and movable support legs that can independently position tissue retractors at different locations around the injection site, allowing each segment to address specific tissue stability needs
Solution Approach 2:
The tripod attachment acts as an intermediary device between the practitioner and the tissue, providing mechanical support through adjustable legs that hold retractors, thereby mediating the interaction and reducing the need for manual tissue manipulation
2Productivity
If existing methods are used, then injection can be administered, but patient discomfort and anxiety increase
Solution Approach 1:
The device performs preliminary tissue retraction and stabilization actions before the injection is administered, preparing the site in advance to minimize patient discomfort during the actual injection process
Solution Approach 2:
The tripod attachment is self-stabilizing through its three-legged design that naturally distributes weight and maintains balance, and the retractors automatically hold tissue position without requiring continuous manual adjustment, reducing patient anxiety through consistent, predictable support
3Ease of operation
If manual assistance is used, then injection can be administered, but practitioner control and precision are reduced
Solution Approach 1:
The tripod attachment combines multiple functions into a single device: the base attaches to the syringe for stability, the adjustable legs position retractors, and the structure provides a stable platform for needle insertion, thereby improving injection accuracy while maintaining ease of operation
Solution Approach 2:
The device incorporates dynamic adjustability in the leg positions and retractor placement, allowing the practitioner to optimize the setup for each specific injection site while maintaining overall procedural ease and precision

AI summary
A tripod attachment for a syringe including a ring-shaped base, a plurality of upright supports pivotably connected to the base, and a flexible loop connected to and encircling the upright supports. Each of the upright supports includes an upright post, a pressure pad at a first end of the upright post, a pivot connector at a second end of the upright post, and a side clasp extending from the post between the pressure pad and the pivot connector. The flexible loop extends through the side clasps to secure the flexible loop to the upright post. The pivot connector pivotably connects the upright post to the base. In an embodiment, the pivot connector includes a pivot ring extending from a second end of the upright post.
