Surgical Drape Segmentation for Sterile Table Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical draping systems for spinal procedures often require breaking sterility when rotating the surgical table, limiting access to different spinal regions and increasing the complexity of surgical procedures.
Innovation Solution
A surgical drape system that includes a seal and deployment loops connected to a surgical table, allowing for 360-degree rotation of the patient while maintaining a sterile field, with adhesive strips and telescopic deployment to ensure continuous sterility and access to various spinal approaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional surgical draping is used with table rotation, then access to different spinal regions is improved, but sterility is broken
Solution Approach 1:
The drape is divided into multiple segments: a first drape portion attached to the patient, a second drape portion attached to the surgical table, and a third drape portion connecting them. This segmentation allows each portion to be independently positioned and secured, enabling table rotation without compromising sterility boundaries.
Solution Approach 2:
The third drape portion acts as an intermediary element connecting the first and second drape portions. It extends from the patient toward the surgical table, creating a continuous sterile barrier that moves with the patient during table rotation while maintaining the sterile field boundary.
2Reliability
If the drape is securely attached to maintain sterility, then sterility is preserved, but access to different approaches is limited
Solution Approach 1:
The drape system is designed to be dynamic rather than static. The third drape portion is configured to move with the patient during table rotation, and the drape includes tear-away portions that can be selectively removed to provide access to different surgical approaches while maintaining sterility through the remaining attached portions.
3Ease of operation
If the drape structure is simplified, then ease of application is improved, but ability to maintain sterility during rotation is reduced
Solution Approach 1:
The drape is divided into multiple segments: a first drape portion attached to the patient, a second drape portion attached to the surgical table, and a third drape portion connecting them. This segmentation allows each portion to be independently positioned and secured, enabling table rotation without compromising sterility boundaries.
Solution Approach 2:
The drape is pre-configured with attachment mechanisms and connecting portions before the procedure. The first, second, and third portions are arranged in advance to form a continuous barrier, so that during the procedure, the surgeon simply needs to activate the attachment mechanisms rather than assembling the complete sterile barrier during surgery.

AI summary
A surgical drape includes a seal connectable with a selected surface of a body disposed with a surgical table. A draping is connected with the seal and a track of the surgical table. The draping is movable relative to the seal to define a sterile region about the body. Surgical instruments, systems and methods are disclosed.
