One-Piece Surgical Drape with Separable Sterile Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical draping methods for spinal surgery are time-consuming, complicated, and fail to maintain sterility, especially when using 3D radiographic devices, leading to potential contamination and inaccuracies in navigation technology readings.
Innovation Solution
A one-piece customized disposable surgical drape with a clear plastic region or lens for navigation readability, sterile longitudinal separation, and under-table wrapping capabilities, allowing for efficient and sterile coverage of both the patient and radiographic equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate drapes are used to cover the patient and equipment, then sterile coverage can be provided, but the draping process becomes time-consuming and complicated
Solution Approach 1:
The patent combines multiple separate draping functions into a single integrated drape that simultaneously covers the patient, equipment, and provides sterile barriers. This unified drape eliminates the need to separately position multiple drapes, reducing draping time while maintaining comprehensive sterile coverage of all surgical elements including the patient, radiographic equipment, and surgical field.
2Reliability
If radiological equipment is draped to maintain sterility, then contamination is prevented, but the equipment maneuverability is reduced
Solution Approach 1:
The drape is designed with separable sections that allow the radiological equipment to move through designated openings without compromising the sterile field. The segmented design includes a patient portion, equipment portion, and surgical field portion that can be independently positioned and separated, enabling equipment maneuverability while maintaining sterility through controlled access points.
3Measurement precision
If the reference frame is exposed for navigation readability, then navigation accuracy is improved, but sterility is compromised
Solution Approach 1:
The patent introduces a transparent window or translucent material as an intermediary between the reference frame and the sterile field. This intermediary allows navigation system readings to be taken through the barrier, enabling optical penetration while maintaining the sterile seal. The transparent portion permits laser or optical signals to pass through for reference frame detection without breaching sterility.
4Loss of time
If a one-piece drape is used to simplify the process, then draping time is reduced, but adaptability to different surgical configurations is limited
Solution Approach 1:
The one-piece drape incorporates dynamic, adjustable features including elastic sections, expandable panels, and reconfigurable fastening systems that allow the drape to adapt to different patient sizes, surgical approaches, and equipment configurations. The integrated design maintains flexibility through built-in adjustment mechanisms rather than requiring separate drapes for different scenarios.
