Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual attachment of brachytherapy seeds during lung resection surgery is time-consuming and technically challenging, requiring a more efficient method for delivering radioactive material and buttress elements to anatomical tissue.
Innovation Solution
A brachytherapy delivery device with a carrier line and stylet system for co-delivery of radioactive material and a buttress element, where the carrier line is attached to the stylet and advanced through an opening to facilitate the placement of radioactive seeds near the surgical site, combined with a buttress element designed for reinforcement and hemostasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brachytherapy seeds are manually sewn onto mesh and sutured to tissue, then radiation can be delivered to the target area, but surgical time increases and technical difficulty increases
Solution Approach 1:
The patent combines the brachytherapy seed delivery system with the buttress element into a single integrated device. The seeds are pre-attached to the inner surface of the buttress element, allowing simultaneous delivery of both the reinforcement barrier and the radioactive seeds in one surgical step, eliminating the need for separate manual attachment procedures
Solution Approach 2:
The brachytherapy seeds are pre-positioned and pre-attached to the buttress element before the surgical procedure. This preliminary preparation allows the seeds to be delivered along with the buttress element during the standard surgical workflow, eliminating time-consuming intraoperative seed attachment while ensuring proper positioning
2Reliability
If brachytherapy seeds are manually attached to mesh, then radiation therapy can be provided, but technical challenge increases
Solution Approach 1:
The patent merges the seed attachment function with the buttress element structure. The seeds are affixed to the inner surface of the buttress element, which provides a stable, pre-configured platform for seed placement. This integration eliminates the technical challenges of manual seed attachment to separate mesh while ensuring reliable radiation delivery through the reinforced tissue barrier
Solution Approach 2:
The buttress element serves as an intermediary carrier between the brachytherapy seeds and the target tissue. By attaching seeds to the inner surface of the buttress element, the device provides a stable intermediate platform that simplifies seed placement while maintaining the therapeutic function of delivering radiation through the reinforced tissue
3Reliability
If separate delivery of brachytherapy seeds and buttress element is performed, then each component can be optimized, but surgical time and complexity increase
Solution Approach 1:
The patent combines multiple functions into a single integrated device structure. The brachytherapy seeds are attached to the inner surface of the buttress element, creating a unified device that provides both tissue reinforcement and radiation delivery. This integration maintains component optimization while simplifying the surgical procedure to a single delivery step
