Penile Separator-Fixator with Curved Support for Surgical Field Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for maintaining penile immobility during urethral surgeries are inefficient, as they rely on manual pulling forces that are inconsistent and fatiguing, and existing devices interfere with the surgeon's comfort and field of operation, especially in pediatric cases where smaller surgical fields require precise and comfortable tooling.
Innovation Solution
A penile surgical separator-fixator with a curved plate providing a stable, non-invasive support for the penis, featuring a recessed area and adjustable holes/grooves for thread passage, allowing for controlled tension and immobilization without additional fixations, enabling comfortable and precise surgical access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a metallic annular device is used to fix the penis, then the penis can be held immobile, but the device interferes with the surgeon's hands and affects comfort
Solution Approach 1:
The invention extracts the interfering ventral portion of the penis from the surgical field by placing it on a dedicated support plate, separating it from the dorsal surgical area. This allows the surgeon to operate comfortably on the dorsal side without the annular device interfering with hand movements.
Solution Approach 2:
The invention introduces an intermediary support plate that acts as a mediator between the penis and the surgeon's workspace. The plate supports the ventral portion while leaving the dorsal surgical field clear, resolving the conflict between immobilization and surgical accessibility.
2Force
If manual pulling force is applied by an assistant to hold the penis, then the penis can be positioned, but the pulling force is inconsistent and depends on assistant fatigue
Solution Approach 1:
The invention enables self-service by allowing the surgeon to secure the penis position independently using the support plate and fixation elements, eliminating dependence on the assistant's manual pulling force. The system maintains consistent positioning without human fatigue.
Solution Approach 2:
The invention replaces the manual mechanical pulling system with a structured support and fixation system consisting of a plate, recess, and fixation elements that provide reliable, fatigue-free positioning.
3Stability of the object's composition
If a circumferential device is used to support the penis, then the penis can be held stable, but the device interferes with the surgical field in the ventral area
Solution Approach 1:
The invention extracts the ventral portion of the penis from the surgical field by placing it on a dedicated support plate, separating it from the dorsal surgical area. This allows the surgeon to operate comfortably on the dorsal side without the annular device interfering with hand movements.
Solution Approach 2:
The invention segments the penis support function from the surgical field by using a separate support plate for the ventral portion, allowing independent optimization of both the support stability and the surgical field accessibility.
4Measurement precision
If the surgical field is small in pediatric cases, then precise work is required, but the surgical field becomes even more constrained
Solution Approach 1:
The invention extracts the ventral portion of the penis from the surgical field by placing it on a dedicated support plate, separating it from the dorsal surgical area. This allows the surgeon to operate comfortably on the dorsal side without the annular device interfering with hand movements.
Solution Approach 2:
The invention applies local quality by providing a specialized recess in the support plate that matches the contour of the penile base, ensuring stable and comfortable localization of the organ while preserving maximum freedom of movement for the surgical field.

AI summary
A penile surgical separator-fixator, intended for use in the immobilization of the penis during a surgical intervention of the urethra, comprises a smooth,hard plate (1), made of a material that is not damaging for the user's skin. The plate (1) has in correspondence with one of its edges a curved recess (2) to support the base of the patient's penis, and opposite to said recess (2) a plurality of holes (3) and grooves (4) are provided for the passage of threads for immobilization of the penis during surgery.
