Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone graft delivery systems face challenges in maintaining structural integrity during surgical procedures due to high compression forces, leading to mechanical failure and difficulty in safely and effectively delivering flowable or non-flowable bone graft materials to surgical sites.
Innovation Solution
A multi-barreled syringe encased within an autoclavable shell, integrated with a servo-controlled motorized system, and compatible with spinal or orthopedic navigation systems, to deliver bone graft materials with enhanced pressure control and reduced failure risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a syringe is used to deliver bone graft material, then delivery capability is provided, but the syringe structure fails under high compression forces
Solution Approach 1:
The syringe is nested within a protective outer shell or housing structure that provides mechanical support and distributes compression forces. This nested configuration allows the syringe to function while being protected from excessive forces that would cause structural failure.
Solution Approach 2:
The delivery system utilizes composite material construction, combining the syringe barrel with an integrated outer shell or housing made of different materials optimized for strength and force distribution. This composite structure maintains syringe functionality while resisting compression forces.
2Length of moving object
If minimally invasive access tools are used, then access size is reduced, but bone graft delivery becomes difficult
Solution Approach 1:
The delivery system is segmented into modular components including a compact syringe barrel, plunger mechanism, and delivery needle or catheter. This segmentation allows the system to fit through minimally invasive access points while maintaining the functional capability to deliver bone graft material effectively.
Solution Approach 2:
The system utilizes a long, narrow dimensional configuration that fits through small access points, with the bone graft material delivery occurring through a fine needle or catheter. The delivery mechanism transitions from a bulk insertion approach to a targeted injection approach through a restricted dimension.

AI summary
The present invention is generally related to a bone graft material delivery system and method for use in spinal and orthopedic surgery. In particular, the delivery system includes a flowable or non-flowable bone graft material or composite within a multi-barreled syringe. The multi-barreled syringe is then encased within an autoclavable shell. In this manner, the multi-barreled syringe in the shell (syringe-shell-system) will be able to generate the necessary pressure for delivery of the flowable or non-flowable bone graft material or composite to the desired spinal or orthopedic surgical site.
