Bone Stabilization Cable with Crimp Anchor for Adjustable Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical tools and procedures for securing and stabilizing bone fractures and soft-tissue injuries are time-consuming, complex, and involve multiple steps, making them difficult to perform effectively.
Innovation Solution
A system and method for supporting, redirecting, and fixating a tensioned cable relative to a hole in a bone or around the bone, involving the formation of pass-through holes, anchoring cables, and using crimp bodies and washers to maintain adjustable tension for bone compression and stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tools and procedures are used for cable securing and bone stabilization, then bone fractures can be secured and stabilized, but the procedures become time-consuming and complex with multiple difficult steps
Solution Approach 1:
The cable system is divided into multiple segments including a cable, separate anchor devices, and crimp bodies that can be independently manipulated and positioned. This segmentation allows each component to be optimized for its specific function while simplifying the overall assembly process during surgery.
Solution Approach 2:
Holes are pre-formed in the bone before cable insertion, and anchors are pre-loaded with cable portions. This preliminary preparation eliminates the need for complex in-situ manipulation during the surgical procedure, reducing operational complexity while ensuring reliable bone fracture stabilization.
2Reliability
If conventional sutures or cables are wrapped around bone for fracture fixation, then bone fragments can be held in place, but the procedures are time-consuming and involve multiple in-situ steps that are difficult to perform
Solution Approach 1:
The cable is pre-positioned through holes in the bone and pre-secured with anchors before the surgical procedure begins. This eliminates the need for time-consuming in-situ manipulation and wrapping during surgery, significantly reducing surgical procedure time while maintaining reliable fracture fixation.
Solution Approach 2:
The crimp body acts as an intermediary device that secures the cable to the anchor in a single definitive action. This intermediary mechanism eliminates the need for multiple adjustment steps and complex in-situ securing procedures, reducing surgical time while ensuring reliable fracture fixation.
3Manufacturing precision
If measurable and adjustable tension is applied to the cable for bone compression, then bone fracture reduction and stabilization are improved, but additional anchoring steps are required
Solution Approach 1:
The anchoring system is segmented into separate anchor devices that can be independently positioned and secured at different locations on the bone. This segmentation allows for precise control of cable tension and bone compression while distributing the anchoring steps across multiple simplified, standardized operations rather than one complex procedure.

AI summary
A first method, for reducing and stabilizing at least one of a fracture in, a dislocation of, and a subluxation of at least one bone, includes forming a hole in the at least one bone. The first method also includes anchoring a first portion of a cable relative to the at least one bone and positioning a second portion of the cable in the hole in the at least one bone. With the second portion of the cable positioned in the hole in the at least one bone, the method includes both tensioning the cable to a measurable and adjustable tension and, with the cable tensioned to the measurable tension, anchoring a third portion of the cable relative to the at least one bone.
