Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering bone graft materials to surgical sites lack control and efficiency, particularly in orthopedic procedures, where varying particulate dimensions and forms of bone grafts pose challenges in ensuring timely and secure augmentation of bone quality for prosthetic anchoring and defect repair.
Innovation Solution
A medical compound preparation and delivery system featuring a delivery device with a depressible trigger, a cartridge, and a series of tubes that allow for controlled dispensing of bone graft materials, including a ratchet mechanism and sealing elements to manage gas release, facilitating precise delivery to surgical sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bone graft material is delivered using conventional methods, then the material can be placed at the surgical site, but the delivery process lacks control and efficiency, leading to imprecise placement and potential waste
Solution Approach 1:
The patent introduces a delivery device as an intermediary tool between the bone graft material and the surgical site. This device includes a cartridge containing the bone graft material, a plunger for controlled propulsion, and a dispensing tip for precise delivery. The intermediary device enables both controlled placement precision and efficient delivery by mechanicalizing the transfer process while maintaining control over material flow and placement location.
2Ease of operation
If bone graft material is delivered without a controlled delivery system, then the material can be placed, but control over delivery timing and placement accuracy is lost
Solution Approach 1:
The delivery device incorporates dynamic control mechanisms including a depressible trigger operably coupled to move a plunger, allowing the operator to control the timing and rate of bone graft material delivery. The system transitions from static material storage to controlled dynamic delivery, enabling precise control over when and how much material is dispensed, thereby reducing waste while maintaining ease of operation through intuitive trigger-based actuation.
3Reliability
If a delivery device with multiple moving parts is used, then controlled delivery is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into an integrated delivery device system. The cartridge, plunger, trigger mechanism, and dispensing tip are merged into a single cohesive unit that delivers controlled bone graft material placement. This merging approach maintains reliability through functional integration while managing complexity by consolidating components rather than using separate devices for each function.
4Productivity
If bone graft material is delivered manually without specialized equipment, then the process is simple, but timing control and placement precision are insufficient
Solution Approach 1:
The patent replaces manual mechanical delivery with a specialized delivery device that uses a mechanically actuated plunger system controlled by a trigger mechanism. This substitution maintains the mechanical nature of the delivery process while significantly improving both delivery speed and placement accuracy through engineered control mechanisms, rather than relying on manual manipulation alone.
