Surgical Microscope Drape Segmentation for Clean Field Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microscope drapes face challenges in attaching to surgical microscopes without contaminating the clean field, as the band-shaped drapes can touch unclean surfaces, such as the floor, during the attachment process.
Innovation Solution
A microscope drape design featuring a lens cap attached to the objective lens housing, a protective lens tilted to prevent reflection, and a drape main body with a bag-shaped portion and a band-shaped portion that extends from the opening, facilitating easy attachment while preventing contact with unclean surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a band-shaped second drape is used to cover the lower portion of the surgical microscope, then the attachment operation becomes easier, but the drape may touch the floor and become unclean
Solution Approach 1:
The drape main body is divided into a bag-shaped portion for the upper microscope and a separate band-shaped portion for the lower microscope. This segmentation allows the band-shaped portion to be attached independently without dragging across the floor, eliminating contamination risk while maintaining ease of attachment.
Solution Approach 2:
The band-shaped portion acts as an intermediary element that connects the bag-shaped portion to the lower microscope. It can be temporarily held by the operator during attachment, serving as a mediator that prevents direct contact between the drape and unclean surfaces while facilitating the attachment process.
2Reliability
If the drape main body is made to cover the entire surgical microscope, then clean field protection is improved, but the attachment process becomes more complex and time-consuming
Solution Approach 1:
The drape main body is segmented into functionally distinct portions: a bag-shaped portion for covering the upper microscope and housing the lens cap, and a band-shaped portion for covering the lower microscope. This segmentation simplifies the attachment process by allowing each portion to be attached independently in a logical sequence, reducing overall complexity while maintaining comprehensive coverage.
Solution Approach 2:
The lens cap is pre-attached to the bag-shaped portion before draping the microscope. This preliminary action ensures that the lens cap is positioned correctly and protected from contamination during the drape attachment process, streamlining the overall procedure while maintaining clean field protection.

AI summary
A microscope drape capable of further facilitating an attachment operation thereof to a surgical microscope while keeping a clean condition. The microscope drape includes: a lens cap that is attached to and detached from a housing of an objective lens of a surgical microscope; a protective lens that is attached to the lens cap with being tilted with respect to an optical axis of the objective lens to protect the objective lens; and a drape main body that covers the surgical microscope. The drape main body includes: a bag-shaped portion having a bag shape whose one end is formed to be an opening, to which the lens cap is attached; and a band-shaped portion that extends to form a band shape from a portion in a circumferential direction of the opening of the bag-shaped portion.
