Stem Implant Installation Tool Set for Faster, Lower-Damage Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthopaedic implant surgery tools are inefficient and require multiple tools and steps, leading to increased surgical time and potential bone damage.
Innovation Solution
A specialized set of tools including a primer, broaches, dual-purpose tools, stem insertion tools, and an instrument tray, designed for precise implant installation with reduced bone damage and streamlined surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate tools are used for implant installation, then the implant can be installed, but surgical time increases and bone damage risk increases
Solution Approach 1:
The patent combines multiple separate surgical tools (primer, broaches, impactor, and implant holder) into a single integrated multi-functional tool. The tool features interchangeable components that can be attached to a common handle, allowing the surgeon to perform multiple operations (reaming, broaching, impacting, and implant insertion) without changing tools or setting up separate instruments, thereby reducing surgical time and improving efficiency
Solution Approach 2:
The surgical tool is designed with universal multi-functionality, where a single tool can perform multiple functions through interchangeable components. The common handle accepts various attachments including primers for different bone types, broaches of different sizes, impactors, and implant holders, making the tool adaptable to different surgical needs and eliminating the requirement for multiple specialized tools

3Productivity
If multiple separate tools are used for implant installation, then the implant can be installed, but bone fracture risk increases
Solution Approach 1:
The tool incorporates a primer component that performs preliminary action by pre-conditioning and preparing the bone canal before the main broaching and implantation processes. This preliminary reaming or broaching of the canal reduces the risk of sudden bone failure or fracture during subsequent steps by gradually preparing the bone structure to receive the implant
Solution Approach 2:
The patent combines multiple separate surgical tools (primer, broaches, impactor, and implant holder) into a single integrated multi-functional tool. The tool features interchangeable components that can be attached to a common handle, allowing the surgeon to perform multiple operations (reaming, broaching, impacting, and implant insertion) without changing tools or setting up separate instruments, thereby reducing surgical time and improving efficiency

AI summary
A set of tools for installation of a stem implant into a bone comprises a stem-shaped priming tool 1 having a distal tip 32 and a plurality of cutting teeth 31 along a length thereof and a plurality of stem-shaped broaches 2, 3, 4, 5, 6 of different size. Each of the broaches have a distal tip and a plurality of cutting teeth along a length thereof. The priming tool 1 is shorter than, has more cutting teeth 31 per unit length, and has a sharper distal tip 32 than the smallest broach. A liner exchange tool (95) is provided to withdraw a liner (100) which has been assembled in a stem (111), which in turn has been implanted in a metacarpal. This tool has a threaded head (96) configured to engage a liner by tool rotation.
