Conformal Sterile Drape for Readable Surgical Control Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of medical instruments and control devices into a sterile surgical field poses challenges in maintaining sterility while ensuring optimal usability, as conventional plastic sheets can hinder the operation and readability of control devices.
Innovation Solution
A sterile drape designed to conform to the shape of control devices, providing a snug fit and enhancing usability by allowing clear reading of indicators and unimpeded operation of controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional plastic sheet is used to provide sterile barrier, then sterility is maintained, but usability and readability of control device indicators are hindered
Solution Approach 1:
The sterile drape employs local quality by creating a conforming cavity structure that provides sterile barrier coverage in specific areas while leaving corresponding transparent windows in the same locations to allow visibility of control device indicators. This localized differentiation enables the drape to simultaneously maintain sterility where needed and provide optical access where required.
Solution Approach 2:
The transparent portion of the sterile drape acts as an intermediary element that allows light transmission between the control device indicators and the user's eye while still providing the sterile barrier function. This intermediary structure resolves the contradiction by enabling optical interaction without compromising the sterile boundary.
2Reliability
If a conventional plastic sheet is used to wrap the control device, then sterility is provided, but operational precision and handling are compromised
Solution Approach 1:
The sterile drape is segmented into multiple functional zones: opaque portions providing sterile barrier and transparent portions providing visual access. This segmentation allows different regions of the drape to serve different functions, maintaining sterility where visual access is not needed while preserving operational precision where transparency is provided.
Solution Approach 2:
The drape structure provides local quality by creating a conforming cavity with transparent windows positioned at specific locations corresponding to control device indicators. This localized transparent regions allow precise operation of controls while the rest of the drape maintains sterile barrier integrity.
3Object-affected harmful factors
If a snug fitting drape is used to maintain sterility, then contamination risk is reduced, but readability of indicators and operation of controls becomes difficult
Solution Approach 1:
The transparent portion of the drape serves as an intermediary that allows optical information from indicators to pass through while maintaining the sterile barrier function. This enables the drape to provide a snug fit for contamination protection while simultaneously enabling indicator readability through the transparent windows.
Solution Approach 2:
The drape employs local quality by providing transparent regions at specific locations where indicator visibility is needed while maintaining opaque sterile barrier coverage elsewhere. This localized transparency allows information transmission without compromising the overall sterile enclosure and contamination protection.

AI summary
Systems, devices, and methods provide a sterile drape for a medical implement, such as a control device, to be used within a sterile field during a medical or surgical procedure. The sterile drape can be used to drape or wrap any of various medical implements or instruments in a manner so as to manage aseptic presentation of the instruments within the sterile surgical field. The use of the disclosed systems, devices, and methods can reduce contamination as well as maintain or enhance the usability of the instruments within the surgical field.
