Abstract
A smoke evacuation tubing assembly includes a base sheet having an adhesive disposed on a top side thereof. An elongate tubing member is operably coupled with a top side of the base sheet and includes a cross-section with first and second opposing rounded sidewalls and first and second generally planar sidewalls disposed between the first and second opposing rounded sidewalls. A plurality of apertures are defined through the first rounded sidewall. A central axis of each aperture is directed downwardly toward the top side of the base sheet. A cover sheet is operably coupled with the top side of the base sheet and is configured to engage the first generally planar sidewall of the elongate tubing member.
Core Innovation
The disclosed invention relates to a smoke evacuation tubing assembly configured for surgical smoke removal. The assembly includes a base sheet and an elongate linear tubing member operably coupled with a top side of the base sheet, with a cross-section including first and second opposing rounded sidewalls and first and second generally planar sidewalls disposed between them.
A plurality of apertures is defined through the first rounded sidewall, and a central axis of each aperture is directed downwardly. A cover sheet is operably coupled with the top side of the base sheet and is configured to engage a first generally planar sidewall of the elongate tubing member, and in certain configurations one or more base sheet and/or cover sheet portions extend over the plurality of apertures.
The aperture arrangement and interaction with the cover sheet create open and cover-sheet-closed aperture sets, and the apertures can be positioned relative to a midline. The arrangement is intended to provide low-profile access and conformability for use near a surgical incision site while supporting improved smoke removal with reduced impact on surgeon view.
Claims Coverage
The independent claims cover three related embodiments of a smoke evacuation tubing assembly and specify downwardly directed apertures through a rounded sidewall, together with a cover sheet that engages a planar sidewall to control aperture coverage or alignment. Across the independent claims, the inventive features include the base sheet, the elongate tubing member with rounded and planar sidewalls, the downward aperture central axis orientation, and the cover-sheet engagement and/or overlying alignment to define aperture openings and open/closed aperture sets.
Downwardly directed apertures through rounded sidewall with cover-sheet engagement
A smoke evacuation tubing assembly comprising a base sheet; an elongate linear tubing member operably coupled with a top side of the base sheet and including a cross-section with first and second opposing rounded sidewalls; a plurality of apertures defined through the first rounded sidewall, wherein a central axis of each aperture is directed downwardly; and a cover sheet operably coupled with the top side of the base sheet and configured to engage a first generally planar sidewall of the elongate tubing member.
A base sheet with adhesive and rounded/planar sidewall tubing with downward apertures
A smoke evacuation tubing assembly comprising a base sheet including an adhesive disposed on a top side thereof; an elongate tubing member operably coupled with a top side of the base sheet and including a cross-section with first and second opposing rounded sidewalls and first and second generally planar sidewalls disposed between the first and second opposing rounded sidewalls; a plurality of apertures defined through the first rounded sidewall, wherein a central axis of each aperture is directed downwardly; and a cover sheet operably coupled with the top side of the base sheet and configured to engage the first generally planar sidewall of the elongate tubing member.
Coincident openings aligned through base or cover with downward apertures
A smoke evacuation tubing assembly comprising a base sheet; an elongate linear tubing member operably coupled with a top side of the base sheet and including a cross-section with first and second opposing rounded sidewalls; a plurality of apertures defined through the first rounded sidewall, wherein a central axis of each aperture is directed downwardly; and a cover sheet operably coupled with the top side of the base sheet and configured to engage a first generally planar sidewall of the elongate tubing member, wherein one of the base sheet and cover sheet extends over the plurality of apertures and wherein the one of the base sheet and cover sheet defines a plurality of openings that coincide with the plurality of apertures defined through the first rounded sidewall.
Across the independent claims, the core structure is a base sheet coupled to an elongate tubing member having opposing rounded sidewalls, with a plurality of apertures through a rounded sidewall where each aperture central axis is directed downwardly, and a cover sheet configured to engage a planar sidewall. Additional independent-claim scope includes an adhesive on the base sheet and, in another embodiment, the definition of openings in one of the base sheet or cover sheet that coincide with the apertures to achieve controlled passage or coverage.
