Surgical Drape Sleeve Sealing for Sterile Patient Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical draping systems fail to maintain sterility during the rotation of patients on surgical tables, necessitating the breaking of the sterile field, which complicates spinal surgeries and limits access to different surgical approaches.
Innovation Solution
A surgical drape system with deployment loops and a seal that can be deployed circumferentially around a patient, maintaining sterility during 360-degree rotations by using adhesive tubes and rail-mounted applicators, allowing simultaneous access to multiple surgical approaches without disrupting the sterile field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional surgical drape is used to cover the patient, then sterility is maintained during the surgical procedure, but the sterile field must be broken when rotating the patient to access different surgical approaches
Solution Approach 1:
The surgical drape is divided into multiple independent panels that can be rotated and repositioned relative to each other. The first drape panel and second drape panel can be independently manipulated to maintain the sterile field while allowing patient rotation and access to different surgical approaches without breaking sterility.
Solution Approach 2:
The drape system incorporates movable and adjustable components that allow dynamic reconfiguration during surgery. The deployment loops and drape panels can be moved and repositioned to accommodate patient rotation and different surgical approaches while continuously maintaining the sterile barrier.
2Reliability
If the surgical drape is deployed to maintain sterility, then the sterile region is protected, but the complexity of the drape system increases with multiple components
Solution Approach 1:
The drape system uses nested deployment loops where inner loops are contained within outer loops. The first deployment loop and second deployment loop are nested together, allowing compact storage and organized deployment of the multiple drape panels while maintaining system manageability despite the multiple components.
3Adaptability or versatility
If the patient is rotated on the surgical table to access different spinal regions, then surgical flexibility is improved, but the sterile field is compromised
Solution Approach 1:
The drape system transitions from a static two-dimensional cover to a three-dimensional configurable structure that can rotate and reposition around the patient. The multiple drape panels can be arranged in different spatial configurations to maintain the sterile field while accommodating patient rotation and providing access to different surgical approaches.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures continuous sterility during patient rotation, enabling unencumbered access to various spinal regions, reducing the need to break sterility and enhancing surgical flexibility.

AI summary
A surgical drape includes at least one deployment member connected with draping movable between a non-deployed orientation and a deployed orientation to define a sterile region about a body disposed with a surgical table. The draping includes a first draping and a second draping. A sleeve includes a seal connectable with a selected surface of the body. The sleeve is connectable between the first draping and the second draping to define a sterile passageway including the selected surface. Surgical instruments, systems and methods are disclosed.
