Adjustable Dilator With Extendable Wing For Penile Prosthetic Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for dilating the corpora cavernosum of the penis during penile prosthetic implantation require multiple, progressively larger dilation tools, increasing the complexity and resource requirements of the procedure.
Innovation Solution
A dilator with an extendable wing that can be adjusted to various diameters, eliminating the need for multiple tools by incorporating a knob that changes the effective diameter of the dilator, allowing it to be used as an alternative to traditional dilation tools and reducing the overall number of surgical tools needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple progressively larger dilation tools are used, then the corpora cavernosum can be adequately dilated to various sizes, but the complexity and number of surgical tools required increases
Solution Approach 1:
The dilator is designed with an extendable wing that can be adjusted to multiple positions, allowing a single tool to perform the function of multiple progressively larger dilators. The wing can be extended to different lengths to accommodate various dilation sizes required for different patient anatomies and implant types, eliminating the need for a full set of specialized dilation tools
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 point and can be extended or retracted based on the specific dilation requirements, transforming a static single-size tool into a dynamically adjustable multi-size tool
2Manufacturing precision
If multiple specialized tools are used for different dilation stages, then precise control over dilation size is achieved, but the time and resources required for the procedure increase
Solution Approach 1:
The dilator is pre-configured with an extendable wing mechanism that allows the surgeon to adjust the dilation size as needed during the procedure, eliminating the need to have multiple pre-selected dilation tools prepared in advance. The wing can be extended to the required length before insertion, providing precise control without requiring extensive preparation time
3Device complexity
If a single fixed-diameter dilator is used, then the number of tools is reduced, but the ability to adapt to different patient anatomies is limited
Solution Approach 1:
The dilator features a dynamic extendable wing that can be adjusted to different lengths to accommodate various patient anatomies. The wing is connected through a hinge point allowing it to be extended or retracted based on the specific anatomical requirements, transforming a single fixed tool into an adaptable multi-size instrument
Solution Approach 2:
The dilator's effective diameter parameter can be changed by adjusting the extension of the wing. This allows the same basic tool to be configured for different dilation sizes, enabling adaptation to different patient anatomies without requiring multiple tools with fixed different diameters

AI summary
A dilator configured for dilating tissue of a corpora cavernosum of a penis having a dilation body defined along a longitudinal axis of the dilator and an extendable wing connected to the dilation body. A knob 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.
