Medical Robot Drape Locking Cover for Fast Sterile Reattachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drape units for medical robots fail to adequately isolate clean and unclean areas, leading to difficulties in downsizing the device and inaccuracies during reattachment, which can compromise hygiene and efficiency.
Innovation Solution
A drape unit with a locking cover that includes a slider and a separator main body, where a locking cover is used to maintain the relative positions of the slider and separator main body, ensuring accurate and quick reattachment by covering the through-holes and restricting movement, thereby isolating clean and unclean areas effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drape unit is designed to cover the entire drive section to isolate clean and unclean areas, then isolation effectiveness is improved, but device size increases and downsizing becomes difficult
Solution Approach 1:
The drape unit is divided into a separator main body that covers the drive section and a locking cover that can be detached. This segmentation allows the isolation function to be maintained by the separator main body while the locking cover can be removed when not needed, enabling downsizing of the overall device volume.
Solution Approach 2:
The locking cover is extracted as a separate detachable component from the separator main body. This allows the locking cover to be taken out when not needed for isolation, reducing the volume of the device while maintaining the isolation effectiveness when the locking cover is attached.
2Adaptability or versatility
If the drape unit is made detachable to enable reattachment, then operational flexibility is improved, but alignment accuracy and reattachment speed deteriorate
Solution Approach 1:
The locking cover is designed with predetermined positioning structures that automatically align the separator main body and locking cover relative to each other during attachment. This preliminary positioning action ensures accurate alignment and fast reattachment without requiring complex alignment procedures.
Solution Approach 2:
The locking cover acts as an intermediary component between the separator main body and the external environment. It provides a standardized interface that facilitates quick and accurate reattachment while maintaining the isolation function, thus improving both flexibility and precision.
3Manufacturing precision
If the locking cover is attached to maintain relative positions, then reattachment accuracy is improved, but device complexity increases
Solution Approach 1:
The locking cover incorporates localized positioning structures (such as positioning protrusions or grooves) at specific locations rather than complex positioning mechanisms throughout the entire structure. This local quality approach maintains relative position accuracy while minimizing overall structural complexity.

AI summary
To allow a clean area and an unclean area to be sufficiently isolated from each other and complete attaching a drape unit accurately and in a short time when reattaching the drape unit. An aspect of the present invention is a drape unit with cover, comprising: a drape unit that is disposed between a medical robot and a surgical instrument to transmit power from a power transmission part of the medical robot to the surgical instrument; and a locking cover that can be reattached to the drape unit. The drape unit comprises: a slider having a first engagement portion engaged with the power transmission part and a second engagement portion engaged with the movable part of the surgical instrument; and a separator main body having a through-hole through which a part of the slider is inserted. The separator main body is detachably attached to the medical robot. The locking cover comprises: a main body portion that can cover the entire through-hole; a holding portion that detachably holds a relative position of the main body portion to the separator main body; and a slider holding portion that is provided on the main body portion so as to hold a relative position between the main body portion and the slider and can be engaged with the second engagement portion.
