Tear-Away Surgical Drape With Expandable Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical drapes are difficult to remove without contaminating the sterile field during spinal procedures, especially when imaging is required, as they often need to be lifted over instruments protruding from the incision, posing risks of contamination and operational delays.
Innovation Solution
A surgical drape with a tear-away design featuring interconnected panels and a flexible, transparent plastic window that can expand vertically to accommodate protruding instruments, allowing for clear imaging while minimizing sterility breaches, and enabling easy removal by pulling the panels apart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional drapes are used during spinal surgery, then the sterile field is maintained, but the drape cannot be removed without lifting and contaminating the sterile field
Solution Approach 1:
The drape is divided into two separate panels (first panel and second panel) that can be independently removed. The first panel is removed laterally without lifting, and the second panel is removed by lifting only after the first panel is gone, thereby maintaining sterile field integrity while enabling easy removal
Solution Approach 2:
Instead of removing the drape by lifting it from the top (conventional method), the first panel is removed by pulling it laterally from the side, reversing the traditional removal approach and avoiding contamination of the sterile field
2Illumination intensity
If a transparent window is added to the drape for imaging, then clear visualization is provided, but the drape structure becomes more complex
Solution Approach 1:
A flexible transparent window made of thin film material is integrated into the drape, allowing clear visualization during imaging while maintaining the simplicity and flexibility of the overall drape structure
Solution Approach 2:
The transparent window serves multiple functions: it provides clear visualization for imaging procedures, maintains the sterility of the surgical field, and allows instruments to pass through while remaining covered, thereby adding functionality without proportionally increasing complexity
3Productivity
If the drape is designed to accommodate protruding instruments, then imaging can proceed without removing the drape, but the drape design becomes more complex
Solution Approach 1:
The drape panels are designed with flexible materials and configurations that allow them to dynamically adapt to protruding instruments, expanding or shifting as needed to accommodate instruments while maintaining coverage and sterility
Solution Approach 2:
The transparent window and drape panels are designed to nest around protruding instruments, with the window material conforming to the instrument shapes, allowing instruments to be accommodated within the drape structure without removing or significantly complicating the overall design

AI summary
A surgical drape is made from a pair of rectangular panels of drape material which are interconnected at a separation zone so that the panels to be pulled apart following a procedure. A fenestration is punched out of the material of one of the panels, near the perforated zone. The fenestration is covered by a flexible, transparent plastic window, preferably made of a polyethylene film and the perimeter of the window is bonded to the drape panel around the fenestration. The window is larger than the fenestration, and is folded or gusseted at its corners so that its center can rise well above the plane of the fenestration, in order to provide clearance for instruments which may be protruding from a surgical site over which the drape is placed.
