Bone Anchor Element With Continuous Hollow Space For Flexible Thread Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone anchor systems are often two- or multi-component, requiring assembly during surgery and offering limited flexibility in thread loading, with most systems designed for specific surgical techniques and not adaptable for various applications.
Innovation Solution
A bone anchor element with a proximal section featuring a contoured projection and a continuous hollow space, and a distal section with two transverse through-holes and a gap opening, allowing for flexible thread guidance and loading options, including preloading and intraoperative adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two- or multi-component bone anchor system is used, then the bone anchor can be assembled during surgery, but the device complexity increases and assembly time is required
Solution Approach 1:
The patent combines multiple components (bone anchor body, thread receiver, and threading aid) into a single integrated bone anchor element. The continuous hollow space serves both as a structural component and as a threading channel, eliminating the need for separate assembly steps while maintaining loading flexibility for various surgical techniques
Solution Approach 2:
The bone anchor element is designed with universal functionality to support multiple surgical techniques (conventional screw-in, push-in, and knotless) through its multi-functional structure. The continuous hollow space can accommodate different threading aids and suture configurations, making a single component replace multiple specialized systems
2Productivity
If pre-assembled bone anchor systems are used, then assembly time is eliminated, but adaptability to various surgical techniques is limited
Solution Approach 1:
The bone anchor element incorporates dynamic adaptability through its open architecture with a continuous hollow space that can accommodate different threading aids and suture configurations. The system transitions from a static pre-assembled state to a dynamic intraoperative configuration where the threading aid can be inserted and removed as needed, allowing adaptation to various surgical techniques without compromising surgical efficiency
3Device complexity
If a single-purpose bone anchor is used, then the device structure is simplified, but versatility across different surgical applications is reduced
Solution Approach 1:
The bone anchor element achieves universality through its multi-functional design where the continuous hollow space serves multiple purposes: structural integrity, threading channel for suture material, and interface for various threading aids. This allows a single component to support conventional screw-in, push-in, and knotless techniques across different surgical applications while maintaining relatively simple overall structure

AI summary
A bone anchor element/inserter/system for inserting into a bone and/or fixing tissue to the bone. The bone anchor element has a proximal end, a proximal section, a distal section and a distal end, and the proximal section has on the outside a contoured. On the inside a continuous hollow space in the longitudinal direction there is a proximal opening and a distal opening. The distal section has in the longitudinal direction to the distal end a first transverse through-hole through the plate plane. A first transverse through-hole and a second transverse through-hole are separated by a web. The web has on its proximal side an abutment surface where when an eyelet is pushed through from the proximal opening through the continuous hollow space of the bone anchor element, through the distal opening and through the first transverse through-hole in the longitudinal direction, the eyelet is guided outward.
