Gravity Feed Implant Dispenser Sequential Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for positioning multiple implants, such as in spinal stabilization systems, are time-consuming and complex due to the need for frequent reloading and re-engagement of implants during surgery.
Innovation Solution
A surgical delivery instrument with a handle member, guide shaft, and actuating member that allows for sequential securement of multiple implants without requiring re-loading or re-engagement after each delivery, enabling implants to be fed directly into a receiving member through a guide shaft for secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional surgical instruments are used to deliver multiple implants, then each implant can be delivered individually, but the surgical procedure becomes time-consuming and complex due to frequent reloading and re-engagement
Solution Approach 1:
Multiple implants are pre-loaded into the instrument's magazine or reservoir before the surgical procedure begins. This preliminary loading eliminates the need for repeated reloading operations during surgery, allowing the surgeon to continuously deliver implants without interrupting the procedure to reload the instrument.
Solution Approach 2:
The instrument is divided into functional segments including a magazine for storing multiple implants, a delivery mechanism for sequential release, and a guide shaft for precise positioning. This segmentation allows each component to perform its specific function efficiently, with the magazine holding multiple implants and the delivery mechanism releasing them one at a time in sequence.
2Ease of operation
If traditional instruments require re-loading after each implant delivery, then implant placement can be completed, but the surgical complexity increases due to repeated re-engagement operations
Solution Approach 1:
Multiple implant delivery functions are merged into a single integrated instrument. The instrument combines a magazine for storing multiple implants, a delivery mechanism for sequential release, and a guide shaft for positioning, all in one device. This merging eliminates the need to exchange or reload instruments between implant deliveries, simplifying the surgical procedure.
Solution Approach 2:
The instrument enables continuous delivery of implants without interruption or reloading. The magazine contains multiple implants that can be delivered sequentially through the same instrument without breaking the surgical flow, maintaining continuous useful action throughout the implantation procedure.
3Reliability
If multiple implants are delivered using conventional methods, then all implants can be positioned, but the overall surgical efficiency decreases due to repeated instrument handling
Solution Approach 1:
Multiple implants are pre-loaded into the instrument's magazine before surgery, and the guide shaft is pre-positioned for accurate delivery. This preliminary preparation ensures that when implants are delivered, they are placed accurately without the need for repeated instrument handling that could compromise precision.
Solution Approach 2:
The instrument maintains continuous engagement with the surgical site, delivering implants sequentially without removal or reloading. This continuous action preserves the accuracy of implant placement while significantly improving surgical efficiency by eliminating repeated instrument handling and re-positioning operations.

AI summary
Instruments and methods are provided for delivering multiple implants to multiple implant locations in a patient without requiring a second implant to be loaded onto or engaged to the delivery instrument after delivery of a first implant. The implants can be sequentially engaged, using the delivery instrument, to the patient or to receptacles of one or more receiving members secured to the patient.
