Adjustable Dilator With Extendable Wing For Penile Prosthetic Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for dilating the corpora cavernosum of the penis during penile prosthetic implantation require multiple tools of varying diameters, which can be cumbersome and inefficient, and often necessitate the use of additional tools like Furlow tools and cavernatomes.
Innovation Solution
A dilator with an extendable wing that can be adjusted to various diameters, integrated with a knob mechanism to change its effective diameter, allowing for a single tool to accommodate different anatomies and functions similar to a Furlow tool or cavernatome, reducing the number of necessary surgical tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dilators of varying diameters are used to dilate the corpora cavernosum, then the dilation can be performed with appropriate sizing, but the procedure becomes cumbersome and inefficient requiring multiple tools
Solution Approach 1:
The dilator is designed with an extendable wing that can be adjusted to provide multiple different effective diameters, allowing a single tool to perform the function of multiple dilators with varying sizes. The wing can be positioned at different extensions to create different dilation diameters, making the device universal for various anatomical requirements.
Solution Approach 2:
The dilator incorporates a dynamic extendable wing mechanism that can be adjusted during the procedure. The wing is connected via a hinge and can be extended or retracted to change the effective diameter of the dilator, allowing the device to adapt its configuration rather than being fixed at a single size.
2Adaptability or versatility
If additional tools like Furlow tools and cavernatomes are used during penile prosthetic implantation, then specific surgical functions can be performed, but the surgical complexity increases
Solution Approach 1:
The dilator is designed to combine multiple surgical functions into a single device. In addition to its primary dilation function with adjustable diameter, the dilator can also serve as a Furlow tool for suturing and as a cavernatome for tissue incision, eliminating the need for these separate specialized tools.
Solution Approach 2:
The invention merges the functions of multiple separate surgical tools (dilator, Furlow tool, cavernatome) into a single integrated device. The dilator body incorporates features that enable it to perform suturing operations and tissue cutting in addition to dilation, consolidating what were previously separate tools.
3Adaptability or versatility
If multiple dilators are prepared for different anatomies, then the correct size can be selected for each patient, but the preparation and inventory requirements increase
Solution Approach 1:
Rather than preparing multiple static dilators of different fixed sizes, the invention uses a single dilator with a dynamic extendable wing mechanism. The wing can be extended to different degrees to accommodate different anatomical sizes, eliminating the need to have multiple dilators in inventory.
Solution Approach 2:
The effective diameter of the dilator is changed by adjusting the extension of the wing rather than by selecting from pre-manufactured dilators of different sizes. This parameter adjustment is done dynamically during the procedure, allowing the same physical device to adapt to different anatomical requirements.

AI summary
A dilator (20) configured for dilating tissue of a corpora cavernosum of a penis having a dilation body (22) defined along a longitudinal axis of the dilator and an extendable wing (24) connected to the dilation body. A knob (26) is provided at a first proximal end portion of the dilation body and is configured to communicate with the extendable wing. Rotating the knob extends the extendable wing away from the dilation body and changes an effective diameter of the dilator. Also disclosed is a method of dilating the corpora cavernosum of a penis and a method of implanting a penile prosthetic in the corpora cavernosum of a penis.
