Solution Overview

Problem

The existing penile prosthesis implantation procedures require multiple tools and instruments, which can be inefficient and costly, and there is a need for a more streamlined approach to prepare the penis for implantation.

Innovation Solution

A single instrument with a shaft and a movable dilation head that can measure the length of the corpora cavernosa and dilate the tissue, allowing for improved procedural efficiency by combining the functions of multiple tools typically used in the procedure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate dilation tools and stainless steel rods are used to dilate the corpora cavernosa, then the dilation can be performed effectively, but the procedure becomes complex, time-consuming, and costly

Engineering Contradiction:

Improvedilation effectivenessVSAvoidnumber of tools required

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate dilation tools and stainless steel rods into a single integrated instrument. The instrument includes a shaft with a dilation head that can be advanced along the shaft to dilate the corpora cavernosa, eliminating the need for multiple separate tools while maintaining effective dilation capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single instrument performs multiple functions: it serves as both a measurement tool (with the shaft providing length measurement capability) and a dilation tool (with the dilation head). This multi-functional design replaces the traditional sequence of using separate measurement tools followed by separate dilation tools.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple separate tools are used for measurement and dilation, then precise measurement can be achieved, but the procedure time increases and cost decreases

Engineering Contradiction:

Improvelength measurement accuracyVSAvoidprocedure time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The instrument merges the measurement function (shaft with markings) and dilation function (dilation head) into a single device. The shaft provides precise measurement capability while the dilation head performs the dilation, allowing both functions to be executed in a single procedural step rather than requiring separate tools and steps.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If traditional multiple-tool procedure is used, then adequate dilation can be achieved, but the cost-effectiveness decreases

Engineering Contradiction:

Improvedilation adequacyVSAvoidcost-effectiveness

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent consolidates multiple expensive, single-use tools into a single reusable instrument. The shaft and dilation head form an integrated device that can be sterilized and reused, reducing the overall cost of the procedure compared to using multiple separate disposable or single-use tools.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An instrument configured to prepare a penis for implantation of a penile prosthetic includes a shaft extending between a distal end and a proximal end, a plunger coupled to and movable relative to the shaft, and a dilation head coupled to a distal end of the plunger and disposed around an exterior of the shaft. The dilation head is movable longitudinally along the shaft.
