Surgical Guide Cutting Attachment With Sterile Debris Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical guide production apparatuses face challenges in maintaining a sterile environment during intraoperative use, leading to contamination risks and increased sterilization time, which can result in delayed procedures or the need for additional equipment.
Innovation Solution
The integration of a cutting attachment with a protective barrier drape and a surgical guide carrier with an integrated barrier drape, both of which are designed to create a sterile barrier around the cutting area and the surgical guide production process, respectively, to prevent contamination and maintain sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a production apparatus is used to cut holes or incisions in the impression, then the surgical guide can be produced quickly, but debris is created that can contaminate the surrounding sterile area
Solution Approach 1:
A sterile barrier drape is introduced as an intermediary between the cutting element and the surrounding sterile environment. The drape allows the cutting operation to proceed while preventing debris from contaminating the sterile field, thus maintaining both productivity and sterility.
Solution Approach 2:
A flexible sterile barrier drape is used to create a physical separation around the cutting area. This thin film structure allows for movement and manipulation while maintaining the sterile boundary, enabling debris containment without compromising the speed of the procedure.
2Reliability
If the production apparatus is sterilised, then contamination risk is reduced, but the sterilisation procedure creates downtime during which the apparatus cannot be used
Solution Approach 1:
The sterile barrier drape is designed as a disposable component that is discarded after a single use. This eliminates the need to sterilize the entire production apparatus between procedures, as the sterile field is maintained through the single-use drape, thereby reducing downtime while maintaining sterility.
Solution Approach 2:
The system is divided into sterilizable components (the production apparatus) and disposable components (the sterile barrier drape). This segmentation allows the expensive apparatus to be sterilized less frequently while the disposable drape maintains sterility for each individual procedure, reducing overall downtime.
3Loss of time
If certain parts of the production apparatus are not sterilised, then sterilisation time and cost are reduced, but there is a risk that clinicians may accidentally touch non-sterile areas and contaminate the sterile field
Solution Approach 1:
The sterile barrier drape acts as an intermediary that physically separates sterile and non-sterile areas. This visual and physical boundary prevents clinicians from accidentally contacting non-sterile components, maintaining sterility without requiring complete sterilization of the apparatus.
Solution Approach 2:
The flexible sterile barrier drape creates a clear visual boundary between sterile and non-sterile zones. This transparent or translucent film allows clinicians to see where the sterile field begins and ends, preventing accidental contamination while minimizing sterilization requirements.

AI summary
A surgical guide production apparatus and accessories are provided to simplify the process of using the production apparatus within the surgical environment. A cutting attachment is provided for use on a surgical guide production apparatus. The cutting attachment comprises a cutting element, a connector for connecting the cutting element to a drive mechanism of the surgical guide production apparatus so that the cutting element can be driven by the drive mechanism to modify an impression of a surgical site to produce a surgical guide, and a protective barrier. The protective barrier is configured to be positioned around the cutting element to surround a cutting area to help prevent contaminants from entering or leaving the cutting area during modification of the impression.
