Bone Delivery Syringe with Interchangeable Tips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering bone during medical procedures lack efficient and precise tools for handling and placement of autologous bone, particularly in surgical settings, where accurate delivery and measurement of bone material are crucial.
Innovation Solution
A syringe-based apparatus with a plunger and interchangeable tips, featuring a funnel-shaped top and a cylindrical passageway, allows for the precise delivery of bone by expelling it through a distal opening, with optional features like transparent windows for measurement and interchangeable tips for varying diameters and flow profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a syringe-based apparatus is used for bone delivery, then delivery precision and control are improved, but device complexity increases
Solution Approach 1:
The syringe apparatus integrates multiple functions into a single device: the syringe body holds and delivers bone material, the plunger provides controlled propulsion, the funnel-shaped top facilitates loading, and interchangeable tips enable different delivery configurations. This multi-functional integration achieves precise bone delivery control while managing device complexity through consolidation rather than separate components.
Solution Approach 2:
The device is divided into separable components including the syringe body, plunger, funnel-shaped top, and interchangeable tips. This segmentation allows for easy cleaning, sterilization, and customization of delivery parameters by changing tips, thereby maintaining precision while managing complexity through modular design.
2Adaptability or versatility
If interchangeable tips with varying diameters are provided, then adaptability for different flow profiles is improved, but device complexity increases
Solution Approach 1:
A single syringe body serves as a universal platform that can accommodate multiple interchangeable tips with different internal diameters. This allows the same base device to adapt to different flow requirements and delivery scenarios by simply changing the tip attachment, achieving versatility without requiring multiple complete syringe systems.
Solution Approach 2:
The tip attachment mechanism allows dynamic reconfiguration of the delivery system during or between procedures. The interchangeable tips can be removed and replaced based on specific surgical needs, enabling the device to adapt its flow characteristics dynamically rather than being fixed to a single configuration.
3Measurement precision
If a transparent window is added for bone measurement, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The transparent window utilizes optical properties (transparency) of the syringe body material to enable visual measurement of bone material volume. By incorporating a transparent section or window in the syringe body, the device allows direct visual assessment of the bone material quantity through the wall, adding measurement capability without requiring separate measurement instruments.
4Ease of manufacture
If the plunger is designed for removable reception, then ease of cleaning and sterilization is improved, but device complexity increases
Solution Approach 1:
The plunger is designed as a separate, removable component that can be detached from the syringe body. This segmentation enables independent cleaning and sterilization of the plunger and syringe body, facilitating easier maintenance and sterilization procedures. The removable design allows each component to be processed separately, improving ease of cleaning while the simple attachment interface minimizes the increase in device complexity.

AI summary
Apparatus for delivery of bone includes a syringe body and a plunger. The syringe body includes a tip at a bottom thereof, a funnel-shaped top at the top thereof, and a tubular section having a generally cylindrical interior wall defining a passageway extending from the funnel-shaped top to the tip. The plunger includes an elongate piston, a press head, and a handle. The piston extends between the press head at a lower end of the plunger, and the handle at an upper end of the plunger. The plunger is removably received within the passageway, with an extent of the plunger extending out of the funnel-shaped top away from the syringe body. The syringe body may be loaded with one or more bone pellets or cartridges containing bone.
