Needle Handling Device for Penile Prosthetic Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools for implanting penile prosthetic cylinders lack efficient mechanisms for handling and controlling the needle during the surgical procedure, which can lead to increased risk of needle sticks and tissue trauma.
Innovation Solution
A needle handling device with an attachment section, a needle capturing section, and an intermediate section that allows for controlled attachment and detachment from a penile prosthetic insertion tool, enabling safe and precise handling and extraction of the needle during implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional introducer tool is used to deliver the needle through the corpora cavernosum, then the implantation procedure can be completed, but the surgeon and user face increased risk of needle sticks and tissue trauma due to lack of efficient needle handling and control mechanisms
Solution Approach 1:
The needle handling device acts as an intermediary between the introducer tool and the needle. It includes a needle receiving portion that captures the needle after delivery, a needle capturing portion that secures the needle distal end, and an intermediate section that connects these portions. This intermediary device provides controlled handling and extraction of the needle, reducing the risk of needle sticks and tissue trauma while maintaining the functionality of the traditional introducer tool.
2Ease of operation
If the needle is directly handled during extraction, then the procedure can be completed, but control and safety are reduced leading to potential needle sticks
Solution Approach 1:
The needle handling device is segmented into distinct functional portions: a needle receiving portion for capturing the needle after delivery, a needle capturing portion for securing the needle distal end, and an intermediate section connecting these portions. This segmentation allows each portion to perform its specific function optimally, providing controlled handling and extraction while improving safety.
3Reliability
If a more complex needle handling device is introduced, then safety and control are improved, but the device complexity increases
Solution Approach 1:
The needle handling device merges multiple functions into a single integrated structure. It combines the needle receiving portion, needle capturing portion, and intermediate section into one device that attaches to the introducer tool. This merging provides controlled handling and extraction capabilities without requiring multiple separate instruments, thus improving safety while limiting the increase in overall system complexity.

AI summary
Disclosed in a needle handling device (100) engageable to an introducer tool (20) used for implantation of a penile prosthetic insert in a corpora cavernosum of a penis. The needle handling device includes an attachment section (102), a needle capturing section (104) and an intermediate section (106). The attachment section is provided at a first end of the needle handling device and is releasably attached to the introducer tool. The needle capturing section is provided at a second end of the needle handling device and is configured to capture and extract a needle out of the introducer tool. The intermediate section connects the first and the second end of the needle handling device. A method of implanting a penile prosthetic insert in a corpora cavernosum of a penis using a needle handling device is also disclosed.
