Extended Handle Applicator for Implant Insertion Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applicators for inserting rod-like implants under the skin lack effective handling mechanisms that facilitate accurate positioning and gentle skin lifting, leading to potential distress and inefficiency during the insertion process.
Innovation Solution
The applicator features a handle that extends above at least 30% of the cannula length, with a widening design and increased surface friction for intuitive grasping, along with a rotatable and flexible lever to secure and disengage the implant, ensuring proper angle insertion and minimizing patient discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional handle design is used, then the device structure is simple, but insertion accuracy and skin lifting capability are insufficient
Solution Approach 1:
The handle extends above the cannula in the longitudinal dimension, creating a multi-dimensional structure that provides both insertion accuracy and skin lifting capability without significantly increasing lateral complexity
Solution Approach 2:
The extended handle serves multiple functions: it acts as an insertion guide, a skin lifting tool, and a grasping handle, thereby improving insertion accuracy without adding separate components
2Ease of operation
If the handle does not extend above the cannula, then the device is easier to manufacture, but accurate positioning and gentle skin lifting cannot be achieved
Solution Approach 1:
The handle extends in the longitudinal dimension above the cannula, enabling skin lifting and accurate positioning operations without adding lateral complexity that would complicate manufacturing
3Measurement precision
If the handle extends above the cannula, then insertion accuracy is improved, but the device becomes more complex
Solution Approach 1:
The handle extends vertically above the cannula, creating a positioning reference in the longitudinal dimension that improves measurement precision without adding lateral components
Solution Approach 2:
The extended handle simultaneously serves as a positioning guide, skin lifting tool, and grasping handle, achieving multiple functions with a single structural modification

AI summary
The invention pertains to an applicator (1) for inserting an implant, in particular a rod-like implant (2) containing an active substance, under the skin of a human or animal, comprising a housing (3), a cannula (6) extending from the housing (3), and a handle (15) for grasping and maneuvering the applicator (1) and the cannula (6) during insertion of an implant (2). In accordance with the invention, the handle (15) extends above at least part of the length of the cannula (6). Such a handle facilitates insertion of the cannula and/or accurate positioning of the implant.
