Surgical Tissue Retractor With Angulating Blades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current retractor systems in surgical procedures lack control and refinement in tissue displacement, leading to inadequate access to the surgical site.
Innovation Solution
A retractor system comprising a retractor frame with a first rotatable arm, a second rotatable arm, and a linearly translatable arm, allowing for arc and linear movement of blades to angulate and separate, providing controlled tissue retraction and enhanced access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional retractor systems are used, then tissue displacement is achieved, but control and refinement of tissue displacement is insufficient
Solution Approach 1:
The retractor system divides the tissue retraction function into multiple independent blades (first blade, second blade, third blade) that can be controlled separately. Each blade is attached to different arms (rotatable arms and linearly translatable arm) allowing independent adjustment of each blade's position and angle, providing precise control over tissue displacement while maintaining reliability through segmented control mechanisms.
2Ease of operation
If multiple blades are used for tissue retraction, then access to surgical site is improved, but device complexity increases
Solution Approach 1:
The retractor system merges multiple blades and their control mechanisms into a single integrated retractor frame structure. The first and second rotatable arms and the linearly translatable arm are all coupled to the common retractor frame, allowing multiple blades to be positioned and controlled from a unified structure. This merging approach provides comprehensive surgical site access while managing device complexity through integrated design.
3Manufacturing precision
If blades are moved in arc and line patterns, then tissue retraction precision is improved, but mechanism complexity increases
Solution Approach 1:
The retractor system employs dynamic movement mechanisms where the first and second blades are attached to rotatable arms that move in arc patterns, while the third blade is attached to a linearly translatable arm that moves in straight lines. These dynamic movement capabilities allow precise blade positioning at different locations and angles without requiring overly complex mechanisms, as each arm type provides a simple yet effective motion pattern suitable for its specific blade positioning needs.
