Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current penile prosthetic implantation procedures require the use of needles, which can cause bleeding and discomfort, and involve the handling of sutures, which may be perceived as unnatural by patients.

Innovation Solution

A tool with a pincher and plunger mechanism that allows for the secure grasping and insertion of inflatable penile prosthetic cylinders into the corpora cavernosa without the need for needles, using a tapered plunger to close and open the pincher for easy delivery and release of the cylinder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If needles and sutures are used in the implantation procedure, then the cylinder can be delivered into the corpora cavernosa, but bleeding and discomfort occur

Engineering Contradiction:

Improveimplantation procedureVSAvoidbleeding and discomfort

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent removes needles and sutures from the implantation procedure by using a pincher tool with a grasping mechanism that can directly capture and deliver the cylinder into the corpora cavernosa through a single incision, eliminating the harmful effects of needle punctures and suture handling

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The pincher tool serves as an intermediary device between the surgeon and the cylinder, providing a needle-free method to grasp, manipulate, and deliver the cylinder into the corpora cavernosa while minimizing trauma to the tissue

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a needle is used to deliver the cylinder, then the cylinder can be implanted, but the procedure becomes more complex and less natural

Engineering Contradiction:

Improvecylinder deliveryVSAvoidimplantation tools

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the functions of needle delivery and suture anchoring into a single pincher tool with a grasping mechanism, eliminating the need for separate needle and suture components and simplifying the overall implantation procedure

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The pincher tool performs multiple functions including grasping the cylinder, delivering it into the corpora cavernosa, and securing it in place, replacing the need for multiple specialized tools and making the procedure more natural and streamlined

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method of implanting a penile prosthetic includes using a tool and grasping a penile prosthesis between a first jaw and a second jaw of the tool. The method includes inserting the first jaw and the second jaw and a portion of the penile prosthesis into the dilated corpora cavernosum, releasing the penile prosthesis from the jaws, and removing the jaws out the dilated corpora.
