Bone Implant Receiving Apparatus Threaded Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone implants cause substantial damage to bone tissue during installation, either through self-tapping threads or impact-driven methods, leading to prolonged healing times and tissue destruction.
Innovation Solution
A bone implant receiving apparatus with a core and wall structure featuring angled or positioned threaded bores, projections, and back-biting fins to minimize tissue damage, allowing for secure attachment without extensive bone destruction, and a kit including medical-grade screws, stints, and implant engaging members for affixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If self-tapping threads are used to secure the implant, then the implant achieves firm attachment to the bone, but substantial damage is caused to the surrounding bone tissue
Solution Approach 1:
The implant is divided into two functional parts: a minimally invasive insertion component that creates a pilot hole without extensive bone removal, and a separate threaded component that provides secure attachment. This segmentation allows the implantation process to occur in two stages, first minimizing tissue damage and then achieving firm attachment.
Solution Approach 2:
A pilot hole is created in the bone before inserting the threaded portion of the implant. This preliminary action removes only the minimal bone necessary to accommodate the implant threads, rather than requiring extensive bone removal or self-tapping that causes substantial damage. The pilot hole preparation enables the subsequent threaded insertion to cause minimal additional trauma.
2Strength
If impact force is used to drive the implant stem into the marrow, then the implant achieves secure fixation, but a considerable part of the marrow is destroyed
Solution Approach 1:
The traditional impact-driven mechanical insertion method is replaced with a threaded insertion mechanism. Instead of using impact force to drive the implant into the marrow (which destroys considerable marrow tissue), the implant is threaded into a pre-prepared pilot hole. This substitution of the insertion mechanism eliminates the need for high-impact forces while achieving equivalent or superior fixation security through thread engagement.
3Strength
If a bolt-and-nut securement arrangement is used to support the artificial hip joint head, then the implant achieves stable support, but considerable space is required and substantial destruction of bone and marrow tissue occurs
Solution Approach 1:
The bolt-and-nut securement arrangement, which requires separate components and considerable space, is merged into an integrated threaded implant structure. The implant combines the functions of the bolt (insertion component) and nut (retention component) into a single threaded device that can be inserted in one piece. This merging eliminates the need for separate securing components and reduces the overall space required in the bone structure.
Solution Approach 2:
The implant is designed as a multi-functional device that performs multiple functions: it creates its own pilot hole through minimal bone removal, provides threaded securement for stable support, and eliminates the need for separate bolts or nuts. This universal design consolidates what would otherwise require multiple separate components into a single implant, reducing both space occupation and tissue destruction.
