Powered Driver Intraosseous Device for Bone Marrow Harvesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for accessing and retrieving bone and bone marrow are often traumatic, labor-intensive, and inefficient, requiring excessive force, multiple insertion sites, and posing risks to both patients and healthcare personnel due to the difficulty in obtaining sufficient bone and bone marrow samples for diagnostic or transplant purposes.
Innovation Solution
A powered driver and intraosseous device with an outer penetrator and optional inner penetrator are used to minimize trauma and efficiently harvest bone and bone marrow, allowing for the removal of sufficient samples with reduced manual effort and increased safety by using a powered driver to insert the device and suction to retrieve specimens through a hollow penetrator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insertion of biopsy needle is used, then device simplicity is maintained, but excessive force is required causing patient pain and potential bone damage
Solution Approach 1:
The patent replaces manual mechanical insertion with a powered driver that uses controlled mechanical force to insert the intraosseous device. The powered driver reduces the operator's manual effort while providing precise control over insertion force, thereby preventing patient pain and bone damage that occur with excessive manual force.
Solution Approach 2:
The patent introduces dynamic control of insertion force through the powered driver, which can adjust force application in real-time during insertion. This dynamic control allows the system to apply sufficient force to penetrate bone cortex while stopping before causing damage, improving ease of operation without harmful effects.
2Productivity
If conventional biopsy needle is used, then procedure simplicity is maintained, but multiple insertion sites are required increasing labor intensity and time
Solution Approach 1:
The patent designs the intraosseous device with multi-functionality, integrating both penetration capability and bone marrow sampling capability into a single device. This universal design allows one insertion site to serve multiple purposes, eliminating the need for multiple separate procedures and significantly improving productivity while reducing time loss.
Solution Approach 2:
The patent merges the functions of bone penetration and bone marrow sampling into a single integrated procedure using one intraosseous device. By combining these functions, the system retrieves sufficient bone marrow samples more efficiently without requiring multiple insertion sites, thereby improving productivity and reducing procedure time.
3Ease of operation
If manual rotation and pressure application is used, then device simplicity is maintained, but loss of control and operator fatigue occur
Solution Approach 1:
The patent replaces manual rotation and pressure application with an automated powered driver system. This substitution eliminates the physical strain and loss of control associated with manual manipulation, while the powered driver maintains precise control through its controlled mechanical actuation system, thereby improving ease of operation and reliability simultaneously.
4Force
If excessive force is applied during harvesting, then penetration through bone cortex is achieved, but penetration through sternum and damage to heart and blood vessels may occur
Solution Approach 1:
The patent employs dynamic force control through the powered driver, which can adjust insertion force in real-time based on resistance feedback. This dynamic control enables the system to achieve necessary penetration force through bone cortex while automatically reducing force when approaching critical structures like the sternum, heart, or blood vessels, thereby preventing damage.
Solution Approach 2:
The powered driver system incorporates feedback mechanisms that monitor insertion resistance and force application. When resistance indicates proximity to critical structures, the feedback system adjusts or stops force application, preventing penetration through the sternum or damage to underlying heart and blood vessels while still achieving adequate bone cortex penetration.
