Arc Lifter Distraction Adjustor for Minimal-Access Histogenesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current distraction histogenesis devices for treating conditions like diabetic foot ulcers and bone defects are cumbersome, painful, and difficult to adjust, requiring numerous external components and percutaneous sites, which complicates surgery and increases infection risk.
Innovation Solution
A distraction device with a rigid elongated member and compliant elongated member, actuated magnetically or via a driver, allows for minimally invasive periosteal distraction by adjusting the distance between tissue layers, reducing the need for external components and percutaneous sites, and promoting tissue regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional distraction histogenesis devices are used, then bone regeneration and tissue expansion can be achieved, but the devices require numerous external components and percutaneous sites that complicate surgery and increase infection risk
Solution Approach 1:
The patent combines multiple functions into a single integrated implantable device that performs both distraction and histogenesis functions, eliminating the need for separate external components and multiple percutaneous sites while maintaining therapeutic effectiveness
Solution Approach 2:
The invention extracts and eliminates unnecessary external components from the traditional distraction histogenesis system, retaining only the essential implantable elements that directly perform the regenerative function, thereby simplifying the overall system
2Reliability
If traditional distraction devices with numerous components are implanted, then distraction histogenesis can be performed, but patient comfort deteriorates due to pain and bother from external components
Solution Approach 1:
The patent removes all external components that cause patient discomfort, retaining only the necessary implantable elements that perform the therapeutic function internally, thereby eliminating pain and bother associated with external hardware
Solution Approach 2:
The invention merges distraction and histogenesis functions into a single implantable device that operates internally without external attachments, improving patient comfort while maintaining therapeutic effectiveness
3Reliability
If traditional devices requiring numerous percutaneous sites are used, then distraction can be achieved, but surgery complexity and infection risk increase
Solution Approach 1:
The patent combines distraction and histogenesis functions into a single implantable device that requires minimal percutaneous access, eliminating the need for multiple surgical sites and reducing infection risk while maintaining distraction capability
Solution Approach 2:
The invention extracts and eliminates the need for multiple percutaneous sites by consolidating all necessary functions into a single implantable device, thereby simplifying surgery and reducing infection risk
4Reliability
If traditional distraction devices are used, then bone and tissue regeneration can be promoted, but the devices are difficult and time-consuming to install
Solution Approach 1:
The patent combines distraction and histogenesis functions into a single pre-assembled implantable device that can be installed in one procedure, eliminating the need for multiple separate implantation steps and reducing installation time while maintaining regenerative effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device facilitates tissue regeneration by creating an artificial space for new tissue growth, minimizing surgery complexity, reducing infection risk, and improving patient outcomes through controlled distraction and retraction of tissue layers.
Implementation Method 1
The rigid elongated member may be magnetically actuated to cause distraction or retraction of the compliant elongated member

AI summary
Systems, methods, and devices for distraction histogenesis. A device includes a rigid elongated member comprising a magnetic portion and a threaded portion. The device includes an adjustment coupler comprising a hollow interior defined by a sidewall, wherein the adjustment coupler comprises internal threading attached to the sidewall. The device includes a compliant elongated member coupled to each of the adjustment coupler and the rigid elongated member. The device is such that rotation of the rigid elongated member causes the threaded portion to screw into or out of the sidewall of the adjustment coupler.
