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

VSEngineering 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

Engineering Contradiction:
Improveimmobility of the penisVSAvoidsurgeon's comfort
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvepulling force on the penisVSAvoidconsistency of pulling force
Core Design Contradiction:
ForceVSReliability

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improvestability of the penisVSAvoidsurgical field area
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #1Segmentation

4Measurement precision

If the surgical field is small in pediatric cases, then precise work is required, but the surgical field becomes even more constrained

Engineering Contradiction:
Improveprecision of surgical workVSAvoidsurgical field area
Core Design Contradiction:
Measurement precisionVSArea of stationary object

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #3Local quality

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.
