Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current circumcision devices, such as the Gomco clamp technique, face challenges with bleeding, incision accuracy, safety, and the required skill level for surgeons, indicating a need for improved apparatuses and methods that enhance usability and safety during the procedure.
Innovation Solution
A rotatable circumcision device with a hand-connectable and disconnectable connector and a cutting member that can be angled and rotated around a tissue holding member, featuring a cutting device with a slot and gripping members for secure attachment and easy operation, allowing for precise and safe removal of penile foreskin tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional circumcision devices like Gomco clamp are used, then the procedure can be performed with existing equipment, but the risk of bleeding and penile injury increases
Solution Approach 1:
The device is divided into separate functional components: a tissue holding member (clamp) that secures the foreskin, and a separate cutting member (blade) that performs the incision. This segmentation allows independent optimization of each component's function, enabling safer tissue clamping and more precise cutting, thereby reducing bleeding and injury risks associated with integrated traditional devices.
Solution Approach 2:
A connector serves as an intermediary component that links the tissue holding member and the cutting member. This connector enables controlled relative movement and positioning between the clamping mechanism and the cutting blade, allowing the surgeon to precisely position the incision relative to the clamped tissue, thus improving safety and reducing harmful effects.
2Manufacturing precision
If traditional circumcision devices are used, then the procedure can be completed, but the accuracy of the incision is compromised
Solution Approach 1:
The cutting member is designed to be rotatable relative to the tissue holding member through the connector mechanism. This dynamic capability allows the surgeon to rotate the blade to different angles and positions around the clamped foreskin, enabling precise control over incision placement and angle. The rotational freedom provides multiple degrees of freedom for accurate positioning while maintaining ease of operation through intuitive manual rotation.
Solution Approach 2:
The connector design provides multiple functions: it connects the cutting member to the tissue holding member, allows rotational movement, and enables easy detachment. This multi-functionality consolidates several operations (attachment, positioning, rotation, detachment) into a single integrated mechanism, improving incision accuracy while reducing the skill level required compared to traditional multi-step procedures.
3Ease of operation
If the cutting device is permanently attached to the tissue holding device, then structural stability is maintained, but ease of operation and cleaning are reduced
Solution Approach 1:
The device is segmented into detachable components connected through a specialized connector. This connector allows the cutting member to be easily attached to and detached from the tissue holding member while maintaining structural stability when connected. The segmentation enables simple cleaning of individual components and easy replacement of the cutting blade, improving ease of operation without significantly increasing overall device complexity.

AI summary
A circumcision device and methods for using and manufacturing the same are disclosed. Embodiments of the circumcision device include a connector that permits the circumcision device to be connected by hand to and disconnected by hand from a tissue holding member while the tissue holding member is holding penile tissue. The connector permits the circumcision device to rotate while connected to the tissue holding member. Embodiments include a blade (cutting member) that is bent at an angle that may be oblique, and the blade may include a slot on either side of or across the bend. Further embodiments include at least one gripping member that extends perpendicularly to the axis the device rotates around, while additional embodiments include at least one gripping member that is aligned with the connector to assist in connection and removal of the device from a tissue holding member.
