Grooved Barrel Tool for Penile Prosthetic Cylinder Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current penile prosthetic implantation procedures involve the use of a Keith needle, which can cause bleeding and discomfort, and require a suture to push the cylinder into place, making the process less desirable for both surgeons and patients.
Innovation Solution
A tool with a barrel featuring grooves that capture and clamp the deflated prosthetic cylinder, allowing it to be inserted into the corpora cavernosa without the need for a needle, reducing discomfort and eliminating the use of a suture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a Keith needle is used to push the cylinder into place, then the cylinder can be delivered through the dilated corpora cavernosum, but bleeding and patient discomfort occur
Solution Approach 1:
The invention extracts and removes the Keith needle from the implantation procedure. The grooved barrel tool delivers the cylinder without requiring needle penetration through the glans penis, thereby eliminating the bleeding and discomfort associated with needle use while maintaining the ability to deliver the cylinder into place
Solution Approach 2:
The grooved barrel serves as an intermediary tool between the surgeon and the cylinder delivery process. Instead of using a needle to push the cylinder, the grooved barrel with its cavity and lip structure provides a non-invasive mechanism to guide and deliver the cylinder through the dilated corpora cavernosum without penetrating the glans
2Ease of operation
If a suture is used to tow the cylinder into place, then the cylinder can be secured and delivered, but the process becomes more complex and time-consuming
Solution Approach 1:
The invention extracts and eliminates the suture from the implantation procedure. The grooved barrel tool with its clamping lip directly pushes and delivers the cylinder into place without requiring sutures to tow or secure the cylinder, thereby simplifying the procedure and reducing the number of steps required
Solution Approach 2:
The invention merges the functions of measurement, clamping, and delivery into a single integrated grooved barrel tool. The barrel with grooves forming a cavity combines the measurement function (by fitting into the dilated corpora cavernosum) with the delivery function (by using the lip to clamp and push the cylinder), eliminating the need for separate suture-based towing steps

AI summary
A method of implanting a penile prosthetic includes providing a tool having a barrel with a first groove formed in an exterior surface of the barrel and a second groove formed in the exterior surface of the barrel; capturing opposing lateral edges of a deflated penile implant into the respective the first groove the second groove; placing the barrel of the tool and the deflated penile implant into a corpora cavernosum of a penis; removing the barrel from the corpora cavernosum of the penis and leaving the deflated penile implant in the corpora cavernosum of the penis.
