Bone Implant Handling Instrument with Guide Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone implant devices require complex setups, are often unreliable in alignment and holding, and complicate surgical procedures due to their elongate nature and complicated geometry, leading to increased risk of infection and prolonged operating times.
Innovation Solution
A bone implant handling instrument with a guide assembly and implant advancing assembly that allows for straight-line guidance and controlled positioning of bone implants with projections, eliminating the need for separate fasteners or clamps and facilitating easier alignment and placement.
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 in position, but the device complexity increases and the surgical procedure becomes more complicated
Solution Approach 1:
The invention removes the fastener or clamp components from the device system entirely. The implant is designed with a configuration that allows it to be directly secured to the bone without requiring separate fastening elements, thereby eliminating device complexity while maintaining implant holding capability through the implant's own structural design
Solution Approach 2:
The implant is designed to be self-securing through its specific configuration and geometry. The implant structure itself provides the mechanism for attachment to bone, eliminating the need for external fasteners or clamps. This self-service approach reduces device complexity while maintaining reliable implant holding
2Manufacturing precision
If the device is separated from the implant before final positioning, then the implant can be fully seated, but the alignment and bone purchase may be inadvertently altered or compromised
Solution Approach 1:
The invention merges the guiding function and the advancing function into a single integrated device-implant system. The device maintains continuous contact with the implant throughout the entire positioning process, eliminating the separation step that could compromise alignment. This unified approach ensures that guidance and advancement occur simultaneously without altering alignment or bone purchase
3Manufacturing precision
If pre-drilled holes are made small for wrist procedures, then the implant can be properly positioned, but the holes become obscured from the surgeon's perspective by blood and adjacent tissue
Solution Approach 1:
The invention introduces a device that acts as an intermediary between the surgeon and the drilled holes. The device provides a mechanical guide that maintains the drilled holes open and visible during the procedure, preventing them from being obscured by blood and adjacent tissue. This intermediary structure allows the surgeon to clearly see and work with the small pre-drilled holes throughout the surgical process
4Productivity
If multiple steps are performed by multiple individuals, then the procedure can be completed, but the operating time increases and the procedure becomes more complicated
Solution Approach 1:
The invention merges multiple procedural steps into a single integrated operation. The device is designed to perform guiding, advancement, and positioning functions simultaneously, eliminating the need for multiple separate steps and reducing the number of individuals required. This unified approach completes the procedure more efficiently and reduces operating time

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 one 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. A method of placing the bone implant is also provided.
