Medical Implant Packaging Support for Stuck Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical implant packaging devices often cause complications during extraction, as the implant can become stuck in the tube, leading to potential damage and contamination risks, and do not facilitate easy and quick removal.
Innovation Solution
A packaging device with a support inside the main hollow body that limits rotation of the object, allowing for easy extraction by enabling a rotational coupling with an instrument and allowing axial movement when the closure element is open, preventing the object from rotating freely and allowing it to be slid out by inclining the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant is packaged inside a tube closed by a stopper, then the implant is protected during storage and transport, but the implant may become stuck in the tube during extraction, causing complications and potential damage
Solution Approach 1:
The packaging device is divided into distinct functional components: a support structure with a seat that holds the implant, and a main hollow body that provides protection. The support acts as an intermediate element that segments the implant from direct contact with the tube walls, preventing sticking while maintaining protection.
Solution Approach 2:
The support with the seat serves as an intermediary element between the implant and the main hollow body. This mediator prevents the implant from directly contacting the tube walls, eliminating the sticking problem while maintaining the protective function of the packaging.
2Ease of operation
If the implant is freely movable in the tube, then easy extraction is possible, but the implant rotates freely making it difficult to couple instruments accurately
Solution Approach 1:
The support introduces asymmetric constraints on the implant's movement. While the implant can move axially for extraction, rotational movement is constrained by the asymmetric geometry of the support-seat-implant interface, enabling accurate instrument coupling without preventing extraction.
Solution Approach 2:
The system dynamically adapts its constraints based on the direction of force applied. The implant is constrained against rotational movement when lateral forces are applied (during instrument coupling), but remains free to move axially when forces are applied in the extraction direction.
3Ease of operation
If the support allows rotation about the axis of the through-passage, then the object can be easily positioned, but the object cannot be suspended to visualize its length
Solution Approach 1:
The through-passage in the support allows the implant to extend in the axial dimension, enabling visualization of its length. This adds a vertical dimension to the positioning capability, allowing both accurate positioning and full visibility of the implant's length simultaneously.

AI summary
The invention relates to a device for packaging an object, comprising: a main hollow body (100), a closure element (101), and a support (110) housed inside the main hollow body (100), said support being configured to receive an object (150), such as a medical implant. The support comprises a seat having an axial through-hole designed to allow part (170) of the object (150) to extend below the seat, while another part (160) of the object (150) bears on the seat. The packaging device is configured to limit or block the rotation of the support (110) relative to the main hollow body (100) about the axis of the through-hole in the seat. The support (110) is designed to limit or block the rotation of at least part of the object (150) about said axis, whereby the object (150) can move freely out of the main hollow body (100) when the closure element (101) is open. The invention also relates to a corresponding extraction method.
