Circumcision Device Glans Protection Shearing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current circumcision techniques often result in injuries due to inappropriate procedures, leading to the need for plastic and reconstructive surgery and increased healthcare costs, and existing devices do not adequately respect the anatomy of the glans or provide cauterization options.
Innovation Solution
A circumcision device featuring a housing with a handgrip, a guide stem with a concave distal surface, rotatable semi-annular blades, and an actuating mechanism that ensures a perpendicular cut, allowing for safe and anatomically respectful procedures, designed as a disposable tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional circumcision techniques using clips and scalpels are used, then the procedure can be performed, but injuries to the glans anatomy occur and reconstructive surgery is required
Solution Approach 1:
The patent introduces a guide part with a stem and shearing template as an intermediary device between the surgeon's control and the cutting blades. The guide part with its concave distal surface and tapered side surface provides a predetermined path and positioning system that ensures the blades cut exactly perpendicular to the penis axis, preventing injuries to the glans anatomy while maintaining surgical effectiveness
Solution Approach 2:
The patent replaces the traditional manual scalpel cutting mechanism with a controlled shearing mechanism. The blades are driven by an actuating mechanism that rotates them into a closed position, providing precise mechanical control over the cutting action. This substitution eliminates the variability and potential for error associated with manual scalpel use, ensuring consistent perpendicular cuts that protect glans anatomy
2Productivity
If existing circumcision devices are used, then cutting can be performed, but the anatomy of the glans is not respected and cauterization is not provided
Solution Approach 1:
The patent integrates multiple functions into a single device: the guide part provides anatomical positioning and guidance, the blades perform the cutting function, and the system is designed to work with cauterization (either integrated or as a subsequent step). The shearing template with its specific geometry serves both as a cutting guide and as a means to ensure anatomical respect, making the device versatile and adaptable to the specific requirements of circumcision while protecting glans anatomy
3Ease of manufacture
If a simple and low-cost circumcision device is used, then the device can be made disposable, but adequate protection of glans anatomy and precise cutting control may be compromised
Solution Approach 1:
The patent divides the device into distinct functional segments: a housing with handgrip, a separate guide part with stem and shearing template, rotatable blades, and an actuating mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity. The modular design enables precise manufacturing of each part independently, ensuring cutting precision even in a disposable device, while facilitating cost-effective production through standardized components
