Modular Bone Screw Implant for Targeted Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical implants for injecting materials into bone cavities lack precision and safety, often causing unnecessary procedures and risking nerve or soft tissue damage due to their inability to target specific areas effectively.
Innovation Solution
A modular bone screw implant with a hexagonal body, threaded cylindrical holes, and a dedicated injection chamber, combined with complementary micro screws and insertion sleeves, allows for targeted injection by enabling precise placement and control of the injection site through a self-piercing and self-tapping mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional implants are used for injection, then the injection can be performed, but the precision of targeting specific areas is poor and additional procedures are required
Solution Approach 1:
The implant system is segmented into a main implant body and multiple complementary implants (plugs) that can be selectively positioned in different bone cavities. Each plug independently controls injection at its specific location, enabling precise targeting without requiring additional external procedures or instruments.
Solution Approach 2:
The complementary implants (plugs) are nested within the main implant body, with each plug inserted into a corresponding cavity of the main implant. This nested structure allows the plugs to be positioned and secured within the main implant, creating an integrated system that provides precise injection control from a single implanted device.
2Reliability
If conventional implants are used for injection, then the injection can be performed, but the risk of damaging nerves or soft tissues is high
Solution Approach 1:
The system provides local quality control by allowing selective placement of plugs in specific cavities of the main implant. This enables the practitioner to control injection at precise locations away from nerves or soft tissues, while leaving other cavities unplugged to prevent injection in dangerous areas. The local quality of each cavity can be independently configured based on anatomical considerations.
3Adaptability or versatility
If multiple separate injections are performed to achieve targeted delivery, then complete coverage can be achieved, but additional detrimental procedures are required
Solution Approach 1:
Multiple injection functions are merged into a single implant system. The main implant contains multiple cavities that can each receive a plug, combining what would otherwise require multiple separate injection procedures into one integrated device. This allows complete targeted coverage to be achieved through a single implantation procedure rather than multiple separate injections.

AI summary
Disclosed is an implant through which a liquid or pasty material can be injected in a targeted manner. This implant is composed of: a main implant with a lumen extending along its entire length, the body of the main implant being of hexagonal cross section, with the plane faces drilled with internally threaded holes which open into the lumen and are intended to remain open or to be plugged by one or more micro screws of the complementary implants, the distal end and proximal end of the implant being threaded; one or more complementary implants, for each of which the micro screw thereof, intended to cooperate with the internally threaded holes of the main implant, is connected to its insertion sleeve by way of a separable zone. The implant is intended in particular for surgical interventions.
