Traction Pin Assembly With Sterile Adapter for Emergency Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction pin insertion techniques are difficult to perform, especially for untrained users or in time-constrained situations, and often require access to sterile surgical tools and operating rooms, which may not be available in emergency or resource-limited settings.
Innovation Solution
A traction pin assembly comprising a traction pin with a couplable shaft and adapter, a guide for stabilizing and steering, and a cap to prevent inadvertent puncturing, which can be used with a driver and sterile cover to facilitate quick and intuitive insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical tools and operating rooms are used for traction pin insertion, then sterilization and infection control are ensured, but the procedure becomes complex, time-consuming, and inaccessible in emergency or resource-limited settings
Solution Approach 1:
The system divides the insertion procedure into separate components: a sterile adapter that interfaces with the traction pin and a non-sterile driver tool. This segmentation allows the critical sterile interface to be isolated while the driving mechanism can be simple and non-sterile, reducing overall procedure complexity while maintaining infection control at the critical interface.
Solution Approach 2:
The adapter serves as an intermediary component between the sterile traction pin and the non-sterile driver. It creates a sterile barrier that allows torque transmission while preventing contamination, enabling simple tool use without compromising infection control.
2Reliability
If traditional surgical techniques are used for traction pin insertion, then proper stabilization is achieved, but the procedure requires extensive training and experience to perform correctly
Solution Approach 1:
The adapter and driver system is designed to be self-aligning and self-retaining. The adapter automatically engages with the traction pin and the driver engages with the adapter through simple interface features, eliminating the need for complex alignment procedures or specialized surgical techniques. This makes the system intuitive for users with minimal training.
3Productivity
If rapid insertion is prioritized in emergency situations, then response time is reduced, but the risk of improper insertion and complications increases
Solution Approach 1:
The adapter is pre-attached to the traction pin before insertion, and the interface between adapter and driver is designed for immediate engagement without complex setup. This preliminary preparation allows the operator to simply attach the driver and insert, ensuring proper alignment and retention from the start of the insertion action, thus maintaining accuracy while enabling rapid deployment.

AI summary
Example embodiments provide traction pin assemblies, components, systems, and methods. An example traction pin in assembly comprises a pin insertable into bone tissue to stabilize the bone tissue. The traction pin comprises a shaft extending between an end of the traction pin and a tip of the traction pin. The end of the traction pin is couplable to a driver that is operable to rotate the pin. The assembly may also comprise an adapter that is couplable to the driver to axially retain the traction pin relative to the driver. The assembly may also comprise a guide that defines a passage through which a portion of the shaft of the traction pin extends and provides a surface for gripping the guide. The surface has a larger surface area than a surface of the portion of the shaft extending through the guide.
