Surgical Retractor Bell Curve Wings Ergonomic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical retractors are not ergonomically designed, require continuous upward pressure, and lack self-supporting capabilities, leading to user fatigue and inconsistent surgical window sizes during procedures like abdominoplasty.
Innovation Solution
A surgical retractor with a blade featuring a pair of wings disposed below the spine, providing a self-supporting structure with a bell curve shape and adjustable surgical window, and a handle with ergonomic curves to facilitate easy rocking and precise control, ensuring consistent access without deforming the wings or requiring continuous pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional surgical retractors are used, then the surgical procedure can be performed, but the user experiences fatigue and requires continuous upward pressure
Solution Approach 1:
The retractor blade is designed with a self-supporting structure featuring a bell curve shape with wings disposed below the spine. This configuration allows the blade to maintain the surgical window opening without requiring continuous manual pressure, enabling the device to support itself during the surgical procedure and reduce user fatigue.
2Ease of operation
If traditional surgical retractors are used, then access to surgical site is provided, but the surgical window size becomes inconsistent during procedures
Solution Approach 1:
The retractor blade incorporates a bell curve shape with specifically configured wings disposed below the spine. This curved geometric design provides consistent mechanical support that maintains a uniform surgical window size throughout the procedure, eliminating the inconsistency associated with traditional straight-edged retractors.
3Reliability
If continuous upward pressure is applied, then the surgical window is maintained, but user strain increases
Solution Approach 1:
The self-supporting blade structure with bell curve geometry and wings below the spine enables the retractor to maintain the surgical window opening through its own structural integrity rather than requiring continuous force application by the user, thereby maintaining reliability while reducing strain.
4Ease of manufacture
If simple retractor design is used, then manufacturing is easier, but ergonomic control and precision are reduced
Solution Approach 1:
The bell curve shape with wings disposed below the spine provides ergonomic advantages for precise control during surgery. While the curved geometry adds some manufacturing complexity compared to simple straight designs, the structure remains relatively simple to manufacture while significantly improving ergonomic control and precision.

AI summary
A surgical retractor for abdominoplasty is disclosed. The retractor has a blade which has a pair of wings disposed below a spine which form a surgical window. The pair of wings form a substantially bell curve shape below the spine of the blade. The pair of wings have outer edges which are curved, and which allow the surgical retractor to be rocked by a user to adjust the surgical window. The retractor has a handle which has a grip portion substantially parallel to the spine of the blade and which provides a more ergonomic grip and greater control.
