A medical device for use in the creation of a temporary pneumoperitoneum

Abstract

A medical device for use in the creation of a temporary pneumoperitoneum includes a substantially dome-shaped body having a vacuum port providing a fluid passageway between an underside of the dome-shaped body and an upside of the dome-shaped body. A frustoconical port is provide in the domed-shaped body for reception and through passage of one or more pieces of associated medical apparatus therethrough.

1 . A medical device for use in the creation of a temporary pneumoperitoneum, the medical device comprising a substantially dome-shaped body having a vacuum port providing a fluid passageway between an underside of the dome-shaped body and an upside of the dome-shaped body, the dome-shaped body further comprising a frustoconical port for reception and throughpassage of one or more pieces of associated medical apparatus therethrough. 
     
     
         2 . A medical device as claimed in  claim 1  in which the frustoconical port is closed. 
     
     
         3 . A medical device as claimed in  claim 2  in which the frustoconical port is closed with a plug. 
     
     
         4 . A medical device as claimed in  claim 3  in which the plug comprises a penetrable barrier. 
     
     
         5 . A medical device as claimed in  claim 2  in which the frustoconical port is a blind bore formed in the dome-shaped body. 
     
     
         6 . A medical device as claimed in  claim 5  in which there is provided a target located on the upside of the dome-shaped body coincident with and concentric with the frustoconical port. 
     
     
         7 . A medical device as claimed in  claim 5  in which a thickness of the dome-shaped body at a base of the blind bore is less than or equal to 5 mm thick. 
     
     
         8 . A medical device as claimed in  claim 5  in which a thickness of the dome-shaped body at a base of the blind bore is less than or equal to 1.5 mm thick. 
     
     
         9 . A medical device as claimed in  claim 1  in which the frustoconical port opens outwardly in the direction from the upside of the dome-shaped body to the underside of the dome-shaped body. 
     
     
         10 . A medical device as claimed in  claim 9  in which there is provided a second frustoconical port on the dome-shaped body located above and coincident with the first frustoconical port, wherein the second frustoconical port opens outwardly in the direction from the underside of the dome-shaped body to the upside of the dome-shaped body, the pair of frustoconical ports thereby combining to form a substantially hourglass-shaped port for reception and throughpassage of one or more pieces of associated medical apparatus therethrough. 
     
     
         11 . A medical device as claimed in  claim 1  in which the dome-shaped body further comprises another frustoconical port for reception and throughpassage of one or more pieces of associated medical apparatus therethrough. 
     
     
         12 . A medical device as claimed in  claim 11  in which the first frustoconical port is located substantially centrally at an axis of the dome-shaped body and the other frustoconical port is located on a side of the dome-shaped body spaced apart from the first frustoconical port. 
     
     
         13 . A medical device as claimed in  claim 1  in which there is provided an annular flange located at the base of the dome-shaped body. 
     
     
         14 . A medical device as claimed in  claim 1  in which the dome-shaped body is saucer dome-shaped. 
     
     
         15 . (canceled)
