Vaginal Dilator Base With Step Tapered Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vaginal dilators lack a stable positioning mechanism during penile inversion vaginoplasty surgery, leading to instability and incorrect positioning, which can hinder the formation of a vaginal graft.
Innovation Solution
A vaginal dilator assembly comprising a base and adapter system that securely holds dilators of various diameters in an upright position, with the adapter non-rotatably fitted into the base, and optional features like step tapered sections in the base to accommodate different sizes without the need for multiple adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current vaginal dilators are used without a positioning mechanism, then the device structure remains simple, but the dilator cannot maintain correct position during vaginal graft formation
Solution Approach 1:
The patent introduces a base as an intermediary component that mediates between the dilator and the surgical field. The base provides a stable foundation with a vertical channel that receives and positions the dilator, ensuring correct orientation during vaginal graft formation without complicating the dilator itself.
Solution Approach 2:
The positioning system is segmented into distinct functional components: a base with a vertical channel for positioning, and an adapter that interfaces with the dilator. This segmentation allows each component to be optimized independently while maintaining overall system simplicity.
2Adaptability or versatility
If a single base design is used, then the device complexity is reduced, but it cannot accommodate dilators of different diameters
Solution Approach 1:
The base incorporates a vertical channel with varying cross-sectional dimensions at different heights, creating local quality variations that allow accommodation of different dilator diameters. The channel is wider at the bottom and narrower at the top, providing appropriate support for various dilator sizes within a single unified structure.
3Reliability
If the adapter can rotate in the base, then the adapter fits easily into the base, but the dilator cannot maintain correct orientation during surgery
Solution Approach 1:
The adapter and base channel feature asymmetric geometric profiles that prevent rotational movement. The adapter's cross-sectional shape does not match rotated orientations within the channel, ensuring the dilator maintains correct orientation during surgery while still allowing straightforward vertical insertion.

AI summary
Vaginal dilator assemblies, devices and kits. Assemblies can include a base, and an adapter. The base can have an inner portion and the adapter can have an outer portion that is complimentary to the inner portion of the base such that the adapter is non-rotatably fitted into the base. Vaginal dilator devices can include a base defining a recess aligned with the longitudinal axis of the base. The recess can have a plurality of step tapered sections. Vaginal dilator kits are also provided that include a plurality of vaginal dilators having different diameters. Each of the plurality of vaginal dilators is configured to be axially aligned and securely fitted into one of the step tapered sections of the recess of the base.
