Sterile Channel Pre-Drape Assembly for Modular Surgical Draping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical drapes for computer-assisted surgical systems are complex to manufacture and assemble, requiring specialized parts and processes to combine sleeves and pockets, leading to increased costs and potential compromise of sterility during draping due to bulk and excess material.
Innovation Solution
A sterile channel pre-drape assembly that allows for individual draping of co-located medical devices using single drape sleeves, eliminating the need for specialized parts and processes, and includes a structure with sterile channels to prevent drape sleeve contact with non-sterile surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing surgical drapes are used to cover multiple manipulators, then complete coverage is achieved, but the drapes become complex to manufacture and assemble requiring specialized parts and processes
Solution Approach 1:
The drape is divided into separate modular components: a base drape and individual sleeve assemblies that can be independently attached to each manipulator. This segmentation allows each component to be manufactured and assembled separately using standard processes, eliminating the need for complex specialized assembly while maintaining complete coverage capability.
Solution Approach 2:
The base drape serves multiple functions by providing coverage for the entire manipulator assembly structure, while the sleeve assemblies can be universally applied to different manipulators. This multi-functionality reduces the need for specialized parts and simplifies manufacturing processes.
2Adaptability or versatility
If existing surgical drapes with multiple sleeves are used, then comprehensive coverage is achieved, but manufacturing costs increase due to specialized parts and processes
Solution Approach 1:
By segmenting the drape into a base drape and separate sleeve assemblies, each component can be manufactured using standard, cost-effective processes rather than requiring expensive specialized manufacturing. The modular design allows for simplified production lines and reduced manufacturing complexity.
Solution Approach 2:
The design merges the base drape and sleeve assemblies into a unified coverage system that achieves comprehensive protection without requiring expensive specialized manufacturing processes for each individual component.
3Reliability
If excess drape material is used to ensure complete coverage, then coverage integrity is maintained, but sterility may be compromised during the draping process
Solution Approach 1:
The segmented design with separate sleeve assemblies allows each sleeve to be independently sterilized and handled, reducing the risk of sterility compromise during assembly. The base drape and sleeves can be prepared separately under controlled conditions, minimizing exposure to non-sterile environments.
Solution Approach 2:
The sleeve assemblies can be pre-assembled and sterilized separately before being attached to the base drape during the surgical procedure. This preliminary action allows for controlled sterilization of each component without compromising sterility during the actual draping process.
