Minimally Invasive Spinal Implant Delivery Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for spinal disorders, such as degenerative disc disease and osteoporosis, often require invasive methods that can cause interference with soft tissues and do not effectively address the need for minimally invasive posterolateral fusion techniques.
Innovation Solution
A surgical system and method for implant delivery that includes a device with a body and transverse portion, a cavity, and a movable rod to expel implants through a channel, allowing for minimally invasive and percutaneous posterolateral fusion procedures while avoiding soft tissue engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical methods are used for spinal fusion, then effective treatment of spinal disorders is achieved, but soft tissue interference and invasiveness increase
Solution Approach 1:
The surgical system is divided into separate functional components: a delivery device with channel for implant transport, a separate expelling rod for implant deployment, and a covering for protection. This segmentation allows each component to perform its specific function efficiently while minimizing overall tissue disruption compared to traditional open surgery methods.
Solution Approach 2:
The delivery device acts as an intermediary tool that transports the implant from the surgical site entrance to the target location without requiring direct manual manipulation or open exposure of the surgical site. The covering serves as a protective intermediary that shields the implant during delivery and is removed only when needed, reducing direct handling and soft tissue interference.
2Object-affected harmful factors
If minimally invasive techniques are used, then soft tissue interference is reduced, but implant delivery complexity increases
Solution Approach 1:
The implant is nested within the delivery device channel during transport, and the covering is nested over the implant for protection. The expelling rod is inserted through the delivery device to deploy the implant. This nested arrangement consolidates multiple functions into a compact structure that can be delivered through minimally invasive access while maintaining the necessary complexity for controlled implant deployment.
Solution Approach 2:
The delivery system incorporates movable components including the expelling rod that can be actuated to deploy the implant, and the covering that can be removed or repositioned. This dynamic design allows the system to transition from a compact delivery state to an implant deployment state, managing the complexity through controlled movement rather than fixed complex mechanisms.
3Object-affected harmful factors
If percutaneous techniques are used for posterolateral fusion, then invasiveness is reduced, but precision requirements increase
Solution Approach 1:
The implant is pre-loaded into the delivery device channel and the covering is pre-positioned over the implant before insertion. This preliminary preparation ensures that the implant is securely held in the correct orientation and position within the delivery system, allowing for precise percutaneous delivery to the target posterolateral fusion site without requiring complex real-time adjustments during the minimally invasive procedure.

AI summary
An implant delivery device includes a body having a first portion and a second transverse portion. The second transverse portion defines a cavity in at least a portion thereof. A first member has at least a portion thereof disposable in the cavity and movable relative to the second portion. A second member has a surface disposed about an implant disposable in the cavity. The surface of the second member includes an opening. The first member is engageable with the implant to expel the implant from the cavity and through the opening. Methods of use are disclosed.
