Transgender Penile Prosthesis with Anchoring Holster
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional penile prostheses are not adapted to the anatomy of the transgender population and are prone to high infection rates, often exceeding 20%.
Innovation Solution
A penile implant specifically designed for the transgender population, featuring a holster/seat mechanism affixed to the pubic bone using sutures and coated with vascular graft materials to prevent sliding and infection, with expandable conduits and a rounded pump design for enhanced stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional penile prostheses are used in transgender phalloplasty, then the basic erectile function is achieved, but the infection rate increases significantly (exceeding 20%) and the device is not adapted to the unique anatomy of the transgender population
Solution Approach 1:
The prosthesis incorporates a holster/seat mechanism specifically designed to interface with the pubic bone anatomy of transgender patients, rather than using a universal design. The coating material is applied locally to the portions of the prosthesis that contact tissue, providing targeted infection prevention where it is most needed while maintaining overall device functionality.
Solution Approach 2:
The prosthesis is divided into distinct functional components: an expandable conduit for erectile function, a holster/seat mechanism for anatomical integration with the pubic bone, and a coating layer for infection prevention. This segmentation allows each component to be optimized for its specific function while collectively addressing the unique anatomical and infectious disease challenges of transgender phalloplasty.
2Stability of the object's composition
If conventional penile prostheses are used, then the basic structural support is provided, but the device slides within the phallus fat layer causing trauma and instability
Solution Approach 1:
The holster/seat mechanism is pre-formed with a geometry designed to interface with the pubic bone before implantation. This preliminary structural preparation ensures that when the prosthesis is implanted, the holster immediately engages with the pubic bone to prevent sliding, thereby preventing trauma to the neophallus before any使用过程中 movement can occur.
Solution Approach 2:
The holster/seat mechanism acts as an intermediary structure between the prosthesis and the pubic bone. Rather than the prosthesis directly contacting and potentially sliding within the fat layer, the holster serves as a mediating interface that anchors the device to the stable pubic bone structure, eliminating the sliding problem while distributing forces safely.
3Ease of operation
If the prosthesis is made expandable to provide erection function, then the erectile capability is improved, but the complexity of the device increases with additional components (pump, reservoir, conduits)
Solution Approach 1:
The expandable conduit and holster/seat mechanism are combined into a single integrated prosthesis unit, reducing the number of separate components that need to be implanted and managed. This merging maintains the erectile function through fluid-filled expansion while simplifying the overall device architecture and reducing surgical complexity compared to traditional multi-component systems.
