Integrated Measuring and Dilation Instrument for Penile Prosthesis
Find Innovative SolutionsGenerate Solutions
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 method to measure and dilate the corpora cavernosa for receiving the prosthesis.
Innovation Solution
A single instrument with a shaft for measuring the length of the corpora cavernosa and a movable dilation head that can be longitudinally positioned along the shaft to both measure and dilate the tissue, replacing the need for multiple tools by performing both functions efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate tools are used for measuring and dilating the corpora cavernosa, then measurement precision and dilation effectiveness are achieved, but device complexity and procedural cost increase
Solution Approach 1:
The patent combines the measuring shaft and dilation head into a single integrated instrument. The measuring shaft is inserted into the corpora cavernosa to measure length, and the dilation head is then advanced along the shaft to perform dilation. This merging of previously separate tools (measuring instrument and dilation tool) into one device reduces procedural complexity while maintaining both measurement precision and dilation effectiveness.
Solution Approach 2:
The instrument performs multiple functions: the shaft serves as both a measuring device and a guide for the dilation head, while the dilation head itself performs the dilation function. This multi-functional design allows a single instrument to replace multiple separate tools, reducing device complexity and procedural cost while maintaining the required measurement precision and dilation effectiveness.
2Reliability
If multiple separate tools are used for measuring and dilating the corpora cavernosa, then functional effectiveness is achieved, but procedural time and cost increase
Solution Approach 1:
The instrument enables continuous useful action by allowing the dilation head to be advanced along the measuring shaft in a continuous motion to dilate the corpora cavernosa. This eliminates the need to withdraw the instrument and introduce separate dilation tools, maintaining functional effectiveness while reducing procedural time and improving efficiency.
3Manufacturing precision
If traditional multiple-tool procedure is used, then adequate dilation is achieved, but procedural cost and complexity increase
Solution Approach 1:
The patent merges the measuring shaft and dilation head into one instrument. The shaft provides structural support and measurement capability, while the dilation head performs the dilation function. This combination achieves adequate dilation (maintaining manufacturing precision) while reducing device complexity by eliminating the need for separate dilation tools.

AI summary
A method of preparing an opening formed in a penis for reception of a penile prosthetic includes measuring a length of the opening formed in the penis with a shaft of an instrument, and moving a dilation head longitudinally along the shaft of the instrument and dilating a diameter of the opening formed in the penis.
