Tray System for Soft Tissue Cutting Device Priming and Safety Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for carpal tunnel syndrome, such as the CTR procedure, require efficient and precise methods for cutting the transverse carpal ligament without risking nearby nerves and arteries. Existing devices lack a standardized method for priming and ensuring the proper functionality of the soft tissue cutting device before use.
Innovation Solution
A tray system is introduced that includes a priming slot and a safety slot for a soft tissue cutting device. The method involves positioning the device in the priming slot, attaching a priming syringe, and equalizing pressures to prime the balloons. The device is then tested in the safety slot to ensure proper inflation and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a soft tissue cutting device is used without a standardized priming method, then the surgical procedure can proceed quickly, but the reliability of the device functionality is compromised
Solution Approach 1:
The patent implements a standardized priming method that must be performed before the surgical procedure. This preliminary action ensures the device is properly prepared by equalizing pressures in the balloons and verifying functionality through the safety slot test, thereby guaranteeing reliability before use.
Solution Approach 2:
The device includes self-testing capabilities where the distal end must be positioned in the safety slot to verify proper priming. The device itself performs the functionality check by allowing visual verification that the distal end is blocked from entering the tray body, providing automatic confirmation of readiness without requiring external testing equipment.
2Ease of operation
If the distal end of the device is allowed to enter the tray body, then the device can be easily stored, but the safety verification function is compromised
Solution Approach 1:
The safety slot acts as an intermediary element between the tray body and the distal end of the device. It provides a verification mechanism where the distal end should be blocked from entering the tray body when properly primed. This intermediary structure enables safety verification while maintaining easy storage capability when the device is not in use.

Function Achieved in This Case
The tray system provides a standardized method for priming and testing the soft tissue cutting device, ensuring that it is properly prepared for use in surgical procedures, thereby reducing the risk of complications during carpal tunnel surgery.
Implementation Method 1
priming a balloon disposed on a distal end of the soft tissue cutting device by equalizing a first pressure inside the balloon to a second pressure inside the priming syringe

AI summary
Methods of using a soft tissue cutting device are disclosed. The methods include providing the soft tissue cutting device, positioning the soft tissue cutting device in a priming slot of a tray configured for receiving and holding the soft tissue cutting device, attaching a priming syringe to the soft tissue cutting device, priming a balloon disposed on a distal end of the soft tissue cutting device by equalizing a first pressure inside the balloon to a second pressure inside the priming syringe, removing the soft tissue cutting device from the priming slot, and positioning the distal end of the soft tissue cutting device on a safety slot included in the tray to determine whether the tissue cutting device has been properly primed.
