Bone Void Plug With Recessed Opening And Septum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reconstructive surgical procedures often create bone voids that require filling to stabilize and restore anatomical structure, but existing solutions lack effective means to prevent displacement of bone void fillers before they harden.
Innovation Solution
A bone void plug with a plug body extending along a longitudinal axis, featuring a recessed opening and ports for delivering and securing bone void fillers, including a septum for air-tight sealing and protrusions for improved fixation, which can be made from various materials like PLDLA or PEEK.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bone void fillers are injected into bone voids, then bone stabilization and anatomical restoration are achieved, but the fillers are prone to displacement before hardening
Solution Approach 1:
The bone void plug is inserted into the bone void before the filler is injected, creating a pre-positioned barrier that prevents filler displacement. This preliminary action ensures that the containment structure is in place before the filler is introduced, solving the displacement problem during injection and initial setting phase
Solution Approach 2:
The bone void plug acts as an intermediary element between the injection site and the surrounding bone tissue. It serves as a mediator that receives the filler from the injection needle and transfers it to the bone void cavity, preventing direct contact and potential displacement of the filler material
2Reliability
If bone voids are filled to restore anatomical structure, then bone stability is improved, but the filling process requires additional surgical steps and time
Solution Approach 1:
The bone void plug and the filler delivery system are combined into a single integrated device. The plug contains an internal cavity that receives the filler, and an external port that accepts the injection needle. This merging allows the surgeon to perform both plug insertion and filler injection in a streamlined sequence, reducing the number of separate surgical steps and overall procedure time
3Manufacturing precision
If multiple surgical instruments are used to deliver and secure bone void fillers, then filler delivery precision is improved, but device complexity increases
Solution Approach 1:
The bone void plug is designed with multiple functions integrated into a single device: it provides structural containment for the filler, offers a port for needle access, creates a seal to prevent leakage, and serves as a delivery mechanism. This multi-functionality eliminates the need for multiple separate instruments while maintaining precise filler delivery capability

AI summary
A bone void plug includes a plug body that extends along a longitudinal axis between a proximal face and a distal opening and a recessed opening that extends from the distal opening toward the proximal face. The recessed opening is configured to receive a bone void filler.
