Surgical Retractor Suction Layout for Clear Illuminated Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical retractors face issues with smoke obstruction from electrocautery and potential patient body fluid ingress due to component separation and gaps, compromising visibility and integrity.
Innovation Solution
A surgical retractor design with spaced suction holes and light sources, angled suction channels, and tight component fitting to minimize smoke overlap and prevent fluid ingress, ensuring improved visibility and airtightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a suction tube is connected to an external negative pressure device to suck smoke around the blade, then smoke removal capability is improved, but the overlap between suction area and illumination area causes severe obstruction of the user's view
Solution Approach 1:
The suction channel is configured to extend in a direction different from the longitudinal direction of the blade, creating a spatial separation between the suction area and the illumination area. This dimensional change allows smoke to be extracted from a different spatial zone than where the light illuminates, preventing the overlap that causes view obstruction while maintaining effective smoke removal
2Ease of manufacture
If components of the retractor are separated and combined through assembly to embed suction tube and circuit board, then ease of manufacture is improved, but gaps at joint portions allow patient body fluid to enter and cause circuit failure
Solution Approach 1:
A sealing member is installed at the joint portion between the handle part and blade part to create a fluid-tight seal. This sealing film or shell prevents patient body fluid from penetrating through the assembly gap, thereby maintaining circuit reliability while preserving the benefits of modular assembly
Solution Approach 2:
The sealing member acts as an intermediary element between the handle part and blade part, filling the gap created by assembly and preventing fluid ingress without interfering with the mechanical connection or electrical functionality of the separated components
