Implant Driver With External Clip For Sequential Bone Screw Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone fixation techniques involving the use of bone screws are cumbersome and inefficient, especially for small screws, as they require manual handling and insertion one screw at a time.
Innovation Solution
A bone fixation system that includes an implant driver with an external clip or cartridge that holds multiple bone screws, allowing for sequential feeding and driving of the screws into the surgical site, enhancing precision and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple bone screws are implanted one at a time using manual handling, then each screw can be precisely positioned and driven, but the surgical procedure becomes cumbersome and time-consuming
Solution Approach 1:
Multiple bone screws are pre-loaded into the external clip in a predetermined sequence before surgery. The clip is then attached to the driver, and screws are delivered to the surgical site in the pre-arranged sequence, eliminating the need for manual reloading during the procedure.
Solution Approach 2:
The external clip combines multiple individual screw handling operations into a single integrated component. The clip holds multiple screws simultaneously and feeds them sequentially to the driver, merging what would otherwise be multiple separate manual operations into one automated sequence.
2Productivity
If an external clip holding multiple implants is used, then sequential implantation without manual reloading is enabled, but the device structure becomes more complex
Solution Approach 1:
The system is divided into distinct modular components: the driver, the external clip, and the sterilizable casing. Each component has a specific function, and they can be assembled and disassembled independently. This segmentation simplifies the overall design by allowing each part to be optimized separately while maintaining ease of assembly.
Solution Approach 2:
The external clip is nested within the sterilizable casing, which in turn is attached to the driver. This nested arrangement protects the clip and its contents while maintaining a compact overall structure. The clip can be removed from the casing for sterilization or replacement without affecting the driver.
3Loss of time
If manual handling of each screw is performed, then precise control over each implant is maintained, but procedural time increases significantly
Solution Approach 1:
The external clip is designed to automatically feed and position multiple screws in sequence without requiring manual intervention between each implantation. The clip's mechanical structure inherently provides the sequencing and positioning functions that would otherwise require repeated manual handling, reducing procedural time while maintaining precision.

AI summary
The disclosure an implant driver designed for bone fixation during surgical procedures. The implant driver includes a body with a handle, an attachment member, and an external clip for holding multiple implants. A driver mechanism is integrated into the body to sequentially feed and implant the plurality of implants into the surgical site. The driver is activated by a control element, which can be a button or trigger. The external clip is enclosed in a sterilizable casing to prevent contamination, and the system may include various safety and adjustment features for optimal performance.
