Bone Implant Handling Instrument Guide Assembly Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone implant devices are complex, expensive, and unreliable in terms of consistent alignment and secure holding of the implant, often requiring multiple steps and complicating surgical procedures, which can lead to increased operating time and risk of infection.
Innovation Solution
A bone implant handling instrument comprising a guide assembly and an implant advancing assembly, which guides the bone implant in a straight line and maintains its orientation, allowing for efficient and precise placement of the implant's projections into the bone without the need for fasteners or clamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional devices with fasteners or clamps are used to secure the implant, then the implant can be held during positioning, but the device becomes complex and requires multiple steps for attachment and detachment
Solution Approach 1:
The patent removes the fastener or clamp components from the device system entirely. Instead of using separate attachment mechanisms, the implant is directly positioned and secured through a simplified insertion mechanism where the implant itself engages with the bone structure without requiring external fastening components.
Solution Approach 2:
The implant is designed to be self-securing through its geometric configuration and material properties. The implant automatically engages with the bone structure during insertion, eliminating the need for separate fastening operations. The device leverages the implant's own structural features to achieve secure positioning.
2Stability of the object's composition
If fasteners or clamps are used to secure the device to the implant, then the implant can be stabilized during placement, but the surgical procedure time increases due to multiple steps
Solution Approach 1:
The implant is pre-configured with its securing features integrated into its structure before the surgical procedure. The geometric design and material properties are predetermined to enable direct engagement with bone structures, eliminating the need for intraoperative fastening steps and reducing surgical time.
Solution Approach 2:
The functions of stabilization and securing are merged into the implant's inherent structural design rather than being separate components. The implant's geometry and material properties combine to provide both positioning stability and secure attachment in a single integrated structure.
3Ease of operation
If the device requires separation from the implant before final positioning, then the implant can be freely positioned, but the alignment and bone purchase may be inadvertently altered or compromised
Solution Approach 1:
The device maintains continuous support and alignment guidance throughout the entire insertion process without requiring separation. The implant remains engaged with the device structure from initial positioning through final bone engagement, ensuring consistent alignment and preventing inadvertent displacement or misalignment during the procedure.

AI summary
The combination of: a) a bone implant having a body with a first portion that overlies an outer bone surface and first and second projections; and b) a bone implant handling instrument comprising: a guide assembly; and an implant advancing assembly. With a part of the bone implant handling instrument bearing against at least one bone part, the bone implant can be guided by the instrument in substantially a straight line in a first direction, while being maintained in substantially a same orientation with respect to the straight line, between a starting position and an operative position. The implant advancing assembly has at least one part that is movable against the bone implant to advance it into the operative position wherein the first and second projections are advanced into one or more bone parts and the first portion of the body overlies an outer bone surface.
